How to Make Thanksgiving Side Dishes Ahead of Time
How to make Thanksgiving side dishes ahead of time is life’s simple pleasure! Here’s how to have pecan pie, homemade cranberry sauce, creamy mashed potatoes, and dinner rolls ready to bake BEFORE the Thanksgiving table is set!
Start Thanksgiving Dinner in October with these easy make-ahead recipes, freezer-friendly casseroles, and simple holiday meal-prep tips!
Did you know you can start making Thanksgiving dinner in OCTOBER?!
Yes, baby! October!
And I’m not talking about buying a can of cranberry sauce and sticking it in the pantry. I’m talking about making your mashed potatoes, macaroni and cheese, sweet potato casserole, and even your homemade dinner rolls WEEKS before Thanksgiving.
Welcome to Holiday Headquarters, where we’re making November the most merrily mundane month of the year!
Here’s the thing about Thanksgiving: It’s one meal. ONE! And somehow, we’ve convinced ourselves that every single dish needs to be made from scratch, on the same day, while we’re also cleaning the house, setting the table, and entertaining everybody.
No, ma’am. Not this year!
I’ve spent years figuring out how to make Thanksgiving dinner ahead of time, and I’m here to tell you that your freezer might just be the best sous chef you’ve ever had.
With a little planning, a few disposable aluminum pans, and some space in your freezer, you can have most of your Thanksgiving side dishes ready to go before November even begins.
And here’s my favorite part: You don’t have to do everything in one day.
Make one casserole this weekend. Double your mashed potatoes when you’re already making them for dinner. Prep your homemade cream of mushroom and onion soup while the cutting board is out.
A little here. A little there.
That’s what I call Future Me Approves!
In this guide, I’ll show you which Thanksgiving side dishes you can freeze, how to store them, when to thaw them, and how to create a Thanksgiving cooking game plan that actually works for your life.
Because the goal isn’t to create a picture-perfect Thanksgiving worthy of a magazine cover.
The goal is to make delicious food, gather your people, and actually enjoy the day.
Let’s stock that freezer, y’all!

How to Make Thanksgiving Side Dishes Ahead of Time
Let’s chat about how chaotic Thanksgiving Day can be! Especially if you are the one making the whole meal!
With a little bit of prep work each week leading up to Thanksgiving, you’ll have your entire Thanksgiving meal ready for Turkey Day! Woo hoo!!
Want to get Thanksgiving started before November?
Come join me for Prepsgiving!
We’re spending October doing the little things that make the holiday season feel a whole lot easier. From cleaning out the freezer to making Thanksgiving side dishes ahead of time, I’m helping you get ready one manageable task at a time.
Because Future You deserves to enjoy Thanksgiving, too!
Join Prepsgiving and make November merrily mundane!
Before you start making your Thanksgiving side dishes, gather a few freezer-friendly supplies!
I love keeping disposable aluminum casserole pans, heavy-duty aluminum foil, freezer-safe bags, and a good roll of plastic wrap on hand.
You’ll also want parchment paper if you’re using my favorite trick for freezing casseroles without tying up your baking dishes.
And don’t forget a permanent marker! Label everything with the name of the dish, the date, and the baking instructions.
Sweetpea’s Tip: You don’t need to buy every single thing at once. Prepsgiving is all about doing a little at a time, using what you already have, and making life easier for Future You.
If you’re a member of Sam’s Club (I would assume Costco has something similar!), pick up the Steam Table Aluminum Foil Pans! They sell a 36-pack for $12.88. I love keeping these on hand when I’m taking something to go, making someone a meal, or prepping food beforehand. They’re the perfect size! (They also have coordinating lids; pick those up, too! They’re an extra $9.98, but worth it!)
You could also order these from Amazon; they’re a bit more expensive, but they come to your home, and you don’t have to think about it!
Get a roll of heavy-duty aluminum foil and some plastic wrap with the dispenser. We’ll wrap the tops of the casseroles in foil and then the entire thing in lots of plastic wrap so it’s ready for the freezer.
P.S. That plastic-wrap dispenser is amazing if you’re like me and a one-lady show! Wrapping these casseroles in plastic wrap is difficult if you’re by yourself!
After these key items, you’ll need the usual kitchen equipment for your big Thanksgiving feast.
Don’t worry! In the email series, you’ll see you don’t have to make all the dishes in one day unless you want to! Each week, you’ll make two make-ahead Thanksgiving side dishes. A little at a time, people!
Your Holiday Headquarters Game Plan
Thanksgiving 2026 is Thursday, November 26.
- October 1–11: Make the plan. Decide on your menu, inventory the freezer, check baking dishes, and start your grocery lists.
- October 12–25: Start stocking the freezer. Make mashed potatoes, macaroni and cheese, cream soup, and sweet potato casserole bases.
- October 26–November 8: Finish the big freezer projects. Prepare dressing components, dinner rolls, and any additional freezer-friendly dishes.
- November 9–22: Organize and delegate. Confirm the guest count, assign dishes, plan oven space, and shop for shelf-stable ingredients.
- November 23–25: Thaw and finish. Move frozen dishes to the refrigerator with enough time to thaw, prep fresh ingredients, and finalize the cooking schedule.
- November 26: Enjoy Thanksgiving! Bake and reheat your prepared dishes, finish the fresh recipes, and gather around the table.
Make-Ahead Thanksgiving Recipes
I love the delicious side dishes that are served with our Thanksgiving turkey!
Classic Sweet Potato Casserole, Thanksgiving Mashed Potatoes, Green Bean Casserole- all the good things.
I’ve started making these three ahead of time, so my Thanksgiving day will be smooth sailing!
I’ll also make apple pie and pumpkin pie ahead of time.
I’ll make up the dinner rolls but leave them unbaked, and I’ll chop all the veggies I need for Grandma’s dressing recipe.
I’ve learned a few hacks that make casserole dish recipes feel helpful and “freshly” made.
For recipes with toppers, like green bean and sweet potato, I’ll hold the toppings back and add them when I bake. Instead of putting these casseroles in a foil pan, I’ll store them in a Ziploc baggie, frozen flat, so they thaw easily. Then, you open the bag and plop it into your baking dish.
Of course, if you don’t want to use a zip-top bag, you can use an airtight container that freezes.
Maybe you want to roast Brussels sprouts for your big menu!
You can make these ahead of time.
I’ve never had success freezing blanched Brussels sprouts and then roasting them. I have successfully sliced and diced the sprouts a few days ahead, then roasted them with bacon and balsamic glaze, like in my favorite Brown Sugar Balsamic Brussels Sprout recipe!
Some “last-minute” recipes, like Grandma’s Dressing, must be made on Thanksgiving day because they require the giblets to make a broth for the bread stuffing.
But when you’ve made several items ahead of time, you’ll have plenty of time to make a couple of last-minute recipes! Woo hoo!
When you’re crafting your holiday menu, consider your oven space.
Do you have one oven and you’ll be fighting for space?
That is okay!! The make-ahead dishes must fit in your oven and bake at the same temperature.
Classic Thanksgiving Recipes to Freeze
Thanksgiving Mashed Potatoes are an excellent side dish to make ahead and freeze. I freeze the creamy mashed potatoes directly in a foil pan and bake the day of dinner.
I refreeze any leftover mashed potatoes in Souper Cubes for nights when I need individual servings!
Fun Fact: I make two pans of mashed potatoes and save one for Christmas dinner. I do this for all the sides I’m making ahead — we typically eat the same meal on Christmas as Thanksgiving!
Besides adding pats of butter on top of your mashed potatoes before baking, I sometimes like to sprinkle a little parmesan cheese on top! This creates a delicious topping that gets golden brown and scrumptious!
Green Bean Casserole is one of those make-ahead recipes that is so easy! Open the canned goods, mix the sour cream and green beans, then plop it into a freezer-safe bag. Freeze it flat, ready to go into the casserole dish.
I store the can of onions elsewhere so no one uses it for the French onion topping for the green bean casserole!
For the sweet potato casserole recipe, I follow the same steps as the green bean casserole. I’ll make the sweet potato portion, freeze it in a baggie, and then plop it into the casserole dish. Then, I can top it with either marshmallow or pecan brown sugar streusel.
Southern Sausage and Cornbread Stuffing is another easy recipe to make ahead, freeze, and bake on the day. I like to pour extra turkey stock over my thawed casserole so it’s not dry.
As for make-ahead turkey gravy, I’ve never done it.
The most important thing on the table for me is the gravy. And I love making it from the turkey I roasted, so all the flavors stay cohesive.
While we love to get a jump start on our holiday cooking, turkey dinner should include a few freshly made items, including gravy!
Make-Ahead Macaroni and Cheese for Thanksgiving
If there’s one Thanksgiving side dish I want you to make ahead of time, it’s Sweetpea’s Ultra Creamy Macaroni and Cheese!
This recipe is everything you want in a Southern baked macaroni and cheese: creamy, cheesy, comforting, and absolutely worthy of a place on your Thanksgiving table.
It’s made with five freshly grated cheeses, evaporated milk, and sour cream. And here’s the best part: There’s no roux to make!
It also freezes beautifully, making it one of my favorite dishes to prep during Prepsgiving.
My rule? If you’re making one batch, make TWO!
You’re already boiling the pasta, grating the cheese, and getting all the ingredients out. Why not make an extra pan to freeze?
You can even divide your macaroni and cheese into smaller portions. That way, if you’re hosting a smaller Thanksgiving dinner, you can pull out exactly what you need instead of making enough macaroni and cheese to feed the entire neighborhood.
Although, let’s be clear. Leftover macaroni and cheese is never a problem at Chez Sweetpea!
How to Freeze Macaroni and Cheese Without Losing Your Favorite Baking Dish
Here’s one of my favorite Future Me Approves freezer tricks!
Ever wanted to freeze a casserole ahead of time but didn’t want your favorite baking dish stuck in the freezer for six weeks?
Enter: parchment paper!
This method works wonderfully for fully baked, cooled casseroles, like my Ultra Creamy Macaroni and Cheese.
- Line your baking dish. Before adding the macaroni and cheese, line a freezer-safe baking dish with enough parchment paper to extend over the sides. Smooth it into the corners as best you can.
- Bake and cool. Prepare and bake the macaroni and cheese as directed. Let it cool, then refrigerate promptly until completely chilled.
- Freeze until solid. Place the cooled casserole, still in its parchment-lined dish, in the freezer until frozen solid.
- Lift it out! Use the parchment paper to help release the frozen casserole from the baking dish. You may need to loosen the edges first.
- Wrap it up. Wrap the frozen casserole tightly in freezer-safe packaging, removing as much air as possible. Label it with the recipe name, date, and reheating instructions.
- Return your baking dish to the cabinet! Your casserole is safely tucked away in the freezer, and your favorite baking dish is ready for another recipe.
When you’re ready to serve, unwrap the frozen casserole, remove the parchment paper, and return it to its original baking dish. Thaw in the refrigerator until completely defrosted, then reheat according to the recipe.
A little tip: Don’t put a frozen casserole directly into a hot glass or ceramic baking dish. Extreme temperature changes can crack certain dishes.
And always check that your parchment paper is suitable for the oven temperature you’re using.
How Far Ahead Can You Make Thanksgiving Macaroni and Cheese?
You can freeze my Ultra Creamy Macaroni and Cheese for up to three months, although I love making it in October for Thanksgiving in November.
It’s one of those recipes that makes the holiday season so much easier.
When you’re ready to serve it, let the casserole thaw completely in the refrigerator. A large, deep casserole may take longer than overnight.
Cover it with foil and reheat at 350°F until hot throughout, reaching 165°F in the center. Uncover near the end if you’d like to refresh that gorgeous cheesy top.
And just like that, you’ve crossed one more dish off your Thanksgiving Day cooking list.
Future You is going to be SO grateful.

Make-Ahead Parker House Rolls for Thanksgiving
Is there anything better than a warm, buttery dinner roll on your Thanksgiving plate?!
Especially when it’s perfect for soaking up every last drop of turkey gravy!
Parker House Rolls are one of my favorite things to make ahead of Thanksgiving. They’re soft, fluffy, buttery, and exactly what you want alongside your turkey, mashed potatoes, and dressing.
And here’s the best part: You can do most of the work ahead of time and still serve freshly baked rolls on Thanksgiving Day!
That’s a Future Me Approves moment if I’ve ever heard one!
How I Freeze Parker House Rolls After the First Rise
Here’s my favorite make-ahead trick for homemade Parker House Rolls!
After the dough has completed its first rise, I roll it out, slather it with honey butter, and roll up each Parker House Roll according to the recipe.
Then, I place the shaped rolls on a parchment-paper-lined baking sheet and flash freeze them for one hour. Once they’re firm, I transfer them to a freezer-safe zip-top bag, squeeze out the excess air, and tuck them into the freezer until Thanksgiving!
When I’m ready to bake, I pull out however many rolls I need, arrange them on a prepared baking sheet, and let them thaw and complete their final rise on the counter. For my rolls, I usually allow about an hour, although the time can vary depending on how frozen the dough is and how warm your kitchen is. Look for rolls that are properly puffy before baking.
Then, I bake according to the recipe, and we’ve got warm, buttery, homemade Parker House Rolls for Thanksgiving dinner!
Future Me Approves! All the mixing, kneading, rolling, and shaping happened weeks ago. All I have to do on Thanksgiving Day is let the rolls rise and pop them into the oven.
And here’s the best part: You don’t have to bake the entire batch! Pull out six rolls for a small dinner or the whole bag for Thanksgiving. Your freezer is doing the heavy lifting, baby!
My Thanksgiving Dinner Roll Game Plan
Here’s how I work Parker House Rolls into my Holiday Headquarters schedule.
Early November: Make sure I’ve got all my ingredients, baking pans, and freezer space ready.
One to two weeks before Thanksgiving: Make and shape the rolls, freeze them until solid, and package them for the freezer.
Thanksgiving morning: Take the rolls out of the freezer and allow plenty of time for them to thaw and complete their rise according to the recipe.
Right before dinner: Bake the rolls while the turkey rests or after the other casseroles come out of the oven.
A little melted butter brushed over the tops, and they’re ready for the bread basket!
Can You Bake Parker House Rolls Ahead of Time Instead?
Absolutely!
If you don’t want to worry about yeast dough rising on Thanksgiving Day, you can also bake your rolls ahead of time, cool them completely, and freeze them in an airtight container.
When you’re ready to serve, thaw and gently reheat them according to your recipe.
You won’t have quite the same fresh-from-the-oven experience, but you’ll still have delicious homemade dinner rolls without the Thanksgiving Day fuss.
And if you’re looking for an even simpler option, buy the frozen dinner rolls at the grocery store!
Nobody is handing out awards for making every single thing from scratch, baby.
The goal is to make Thanksgiving dinner easier, not create more work for yourself.
Because when the turkey is carved, the gravy is ready, and everybody is gathered around the table, nobody cares when you made the dough.
They’re just happy you passed the butter!
Easy Thanksgiving Side Dishes to Prep Ahead
Now, let’s chat about the side dishes you can prep components of on Monday, Tuesday, and Wednesday.
If you like to serve a Thanksgiving Salad Recipe, chop and slice all your salad components earlier in the week. Wash your lettuce, then wrap it in paper towels and store it in an airtight container.
This Autumn Chopped Salad is the best recipe, and it is so easy! You can roast the sweet potatoes on Tuesday, slice the grapes, make the croutons, and wash/dry and chop the lettuce all well before Thursday!
You can blanch fresh green beans as early as Monday morning and roast or sauté them on Thanksgiving Day.
You can chop the onions and celery on Tuesday for Grandma’s Dressing recipe. (I chopped these earlier in the month and froze them, but it’s not quite the same.)
The bread for my Grandma’s Dressing Recipe can be torn on Tuesday and stored in an airtight container, ready for the big bowl and buttery stock on Thursday. Although this is my job every year, I watch the Macy’s Day Parade!
Thawing and Baking Your Make-Ahead Thanksgiving Casseroles
Alright, y’all! You’ve made your casseroles, stocked the freezer, and Thanksgiving week is finally here!
It’s time to put all that Prepsgiving preparation to work.
Start moving your frozen casseroles into the refrigerator several days before Thanksgiving. Smaller portions may thaw within a day, while larger, deeper casseroles can take two days or longer.
And please don’t thaw your casseroles on the kitchen counter!
Keep everything refrigerated at 40°F or below until you’re ready to bake or reheat.
On Thanksgiving Day, remove each casserole from the refrigerator when you’re ready to put it in the oven. Follow the individual recipe’s instructions, allowing additional cooking time if the casserole is still cold.
If you’re reheating a previously cooked casserole, use a food thermometer to make sure the center reaches 165°F.
Here’s my favorite oven-space trick: I can fit two aluminum casserole pans on one half-sheet pan. With two oven racks, I can reheat four casseroles at once!
Just remember that a crowded oven may need additional cooking time, so check the temperature of each dish individually.
And there you have it! All that work you did in October is paying off.
Future You approves!
On Thanksgiving morning, or an hour before you need to cook your casseroles, remove them from the fridge and let them come as close to room temperature as possible.
Your oven will likely have just roasted your turkey, so it will be around 325 325˚-350˚ degrees Fahrenheit.
Heat your casseroles in a cold oven if you’re not baking a turkey. This is my favorite way of heating a thawed casserole!
Otherwise, let your casseroles come to room temperature, then place them in the oven. I prefer to place them on a baking sheet in case anything bubbles.
I can fit two aluminum foil pans on a half-sheet pan and two pans in my oven on two racks. This means I can bake four casseroles at once.
For baking your Thanksgiving dessert recipes, I like to bake pies on Wednesday or while we eat.
People enjoy the main course, so you have plenty of time to bake your desserts.
Depending on your timeline, knowing how to make Thanksgiving side dishes ahead of time will serve you well for years to come!
You’ll always be ready to prepare your Thanksgiving menu ahead of time, and you’ll learn what works for you, your freezer/fridge space, and your oven space.
While this guide walks you through making Thanksgiving side dishes ahead of time, adjust as needed to your preferences!
Food Safety Tips for Make-Ahead Thanksgiving Side Dishes
Now, before we start filling every available inch of freezer space with Thanksgiving casseroles, let’s have a little food safety chat!
Because here’s the thing: Making Thanksgiving dinner ahead of time is supposed to make your life EASIER. And nothing ruins a holiday faster than somebody getting sick from improperly stored food.
Whether you’re freezing mashed potatoes, macaroni and cheese, homemade cream soups, or your favorite casseroles, there are a few important rules to follow.
Cool Your Food Quickly Before Freezing
When you’ve finished cooking a big batch of mashed potatoes or macaroni and cheese, don’t leave it sitting on the counter for hours while you go about your day.
The USDA recommends refrigerating perishable foods within two hours of cooking.
Here’s what I recommend:
- Divide large batches into smaller, shallow containers so they cool quickly.
- Refrigerate promptly rather than waiting for everything to reach room temperature.
- Once the food is thoroughly chilled, package it for the freezer.
- Keep your refrigerator at 40°F or below and your freezer at 0°F or below.
Sweetpea’s Tip: When I’m making multiple casseroles for the freezer, I work in batches. That way, I’m not trying to cool six giant pans of hot food at the same time!
How to Safely Thaw Frozen Thanksgiving Casseroles
This is important, y’all!
Please don’t leave your frozen casseroles on the kitchen counter overnight to thaw.
I know it’s tempting, especially when refrigerator space is at a premium during Thanksgiving week, but the safest and easiest way to thaw your make-ahead side dishes is in the refrigerator.
Here’s my Thanksgiving thawing game plan:
- Check your freezer inventory several days before Thanksgiving.
- Move your frozen casseroles into the refrigerator with enough time to thaw completely.
- Keep them covered and refrigerated at 40°F or below.
- Once thawed, follow the individual recipe’s baking or reheating instructions.
Smaller containers may thaw within a day, while large, dense casseroles can take considerably longer.
And remember, a refrigerator packed tightly with frozen casseroles may not circulate cold air efficiently. Give everything some breathing room!
Future Me Approves: Write your thawing day directly on your Thanksgiving Game Plan. That way, you’re not discovering a solid block of frozen macaroni and cheese on Thanksgiving morning.
Reheat Your Thanksgiving Side Dishes to the Proper Temperature
When reheating previously cooked Thanksgiving side dishes, make sure they reach an internal temperature of 165°F.
And no, we aren’t guessing!
A digital food thermometer is one of my favorite kitchen tools because it takes the guesswork out of cooking and reheating.
A few tips:
- Cover casseroles with aluminum foil while reheating to help retain moisture.
- Check the temperature in the center of the dish, where it takes the longest to heat.
- Bring reheated soups, sauces, and gravies to a rolling boil.
- If you’re reheating a large casserole, allow extra time for the center to become thoroughly hot.
For casseroles assembled with uncooked ingredients, follow the original recipe’s cooking instructions and check that the dish reaches its required safe internal temperature.
How Long Can You Keep Thanksgiving Side Dishes in the Freezer?
Here’s the good news: You can absolutely make many of your Thanksgiving dishes in October and enjoy them in November!
Food kept continuously frozen at 0°F remains safe indefinitely, although the quality can decline over time.
For most cooked leftovers, the USDA recommends using frozen portions within three to four months for the best quality.
That’s why I love our Prepsgiving system. We’re preparing these dishes just a few weeks before Thanksgiving, so they’re ready when we need them.
Be sure to label each freezer container with:
- The name of the dish
- The date you prepared it
- Any special baking or reheating instructions
You can also add a reminder about toppings that need to be added after thawing, such as crispy fried onions or a pecan streusel.
Don’t Forget About the Two-Hour Rule on Thanksgiving Day!
Once you’ve worked so hard to prepare a beautiful Thanksgiving meal, let’s make sure those leftovers are safe, too.
Perishable foods shouldn’t sit at room temperature for more than two hours.
If you’re serving buffet-style, keep hot foods at 140°F or above and cold foods at 40°F or below.
After dinner, divide leftovers into shallow containers and refrigerate them promptly.
Refrigerated leftovers should generally be eaten within three to four days, or frozen for later.
And if you aren’t sure how long something has been sitting out?
When in doubt, throw it out, baby!
I love a good leftover Thanksgiving sandwich as much as anybody, but we’re not risking food poisoning for one.
A Little Preparation Makes a Big Difference
You don’t need a professional kitchen or a culinary degree to make Thanksgiving dinner ahead of time.
You just need a plan, some freezer space, and a few good food safety habits.
That’s what Holiday Headquarters is all about: Doing the work ahead of time so you can actually enjoy the holiday when it arrives.
Because Thanksgiving should be about gathering around the table, not spending the entire day stressed out in the kitchen.
Cook ahead. Freeze safely. Gather your people. Enjoy the day.
That’s a Thanksgiving Game Plan Future You can approve of!
Ready to Make November Merrily Mundane?
If you’ve made it this far, you’re already thinking like a Holiday Headquarters hostess!
And I want you to remember something: You don’t have to make every single dish from scratch. You don’t have to do everything yourself. And you certainly don’t have to spend Thanksgiving Day exhausted in the kitchen.
Make what you can ahead of time. Buy what makes sense. Delegate a dish or two.
Host yourself first, baby!
If you’re ready to get your holiday season organized, come join me for Prepsgiving, where we’re making the holidays easier one manageable task at a time.
Because dinner parties can change the world, and that includes Thanksgiving dinner.
