How to Make Easy Cheesy Cauliflower Casserole

keto loaded cauliflower casserole

​First, let’s gather the ingredients we’ll need for this recipe.

Cauliflower — You can use cauliflower florets, the whole head of cauliflower, riced cauliflower, frozen cauliflower… ((Anyone starting to feel like Bubba and shrimp?!))

However you want your cauliflower, you’ll need it steamed so it’s soft and ready to bake. I just steam two bags of frozen cauliflower on the stovetop. The steamed cauliflower makes the most perfect side dish. If you’re using cauliflower rice, this will act more like a grits casserole! Yum. 

​Side Note: I haven’t tried this recipe with mashed cauliflower, I bet it would be wonderful!! 

Cheddar Cheese — You’ll need lots of shredded cheese for this keto diet-friendly loaded cauliflower casserole recipe. I shredded my cheese using this countertop grater, and it’s THE best way to shred cheese!! So easy! I prefer sharp cheddar cheese, but use what you have! And if you have bags of pre-shredded cheese with a little leftover, use them up. This is a great casserole to use up any remaining cheese you have on hand.

Ranch Powder — if you’re not a fan of ranch feel free to leave this out! But, it’s an easy way to pack in flavor without opening a lot of seasoning jars!

House Seasoning — another cheeky way I give lots of flavor to a dish is to use my homemade spice blend. It’s equal parts kosher salt, garlic powder, and onion powder. Add in as much black pepper as you like, then shake it up! Keep it in a jar in your spice cabinet, or better yet, by your stovetop. You won’t believe how much time this saves you!

Bacon — I used the pre-cooked Bacon Bits from Great Value because I’m fancy. It was so easy to toss in this little bag of chopped-up crispy bacon!!

Sour Cream — It’s not a cheesy loaded cauliflower casserole without it! Plus, it binds everything together to create a creamy cheese sauce, right in the casserole dish.

Green Onions — I love fresh sliced green onions. It adds a bright fresh extra flavor to a keto cauliflower casserole recipe. And! It’s one of the main flavors of a loaded baked potato, so you can’t leave it out! Unless you just *really* want to.

Baking this Cauliflower Dish

keto cauliflower bake

This is one of those more than easy, perfect keto recipe ideas. 

When you have all of your ingredients ready to go, this keto cauliflower bake comes together in less than 30 minutes. 

For this tasty casserole, here’s the game plan for ingredient prep:

First, get your cauliflower steaming. Either in the microwave or on the stovetop.

Shred your cheese onto a plate, or paper towel.

Next, you’ll add most of the cheese to a large bowl. Reserve as much cheese as you want for the top of the keto-loaded cauliflower casserole.

On top of the shredded cheese in the bowl, add in your ranch powder, house seasoning, and half of the bacon bits bag. (If you’re using fresh bacon, use 4 slices.)

Give these ingredients a good mix before adding in the sour cream.

After you’ve plopped in your sour cream, snip in your green onions using some clean kitchen scissors. Then stir all of that together!

In the large mixing bowl, dump your steamed cauliflower. I like to give it a little drain in a colander, to be sure I don’t add any extra water to their keto casserole recipe. 

Pour it into a greased baking dish and bake at 350˚ for 15-20 minutes. Since the cauliflower is hot going into your mixing bowl, it’s just melting the cheese and cooking everything through in the preheated oven. 

If you want that *extra* golden brown crunchy, cheesy top of your casserole, broil the top on high for a couple of minutes, keeping a close eye!

​Any leftovers should be stored in an airtight container in the fridge. In the recipe card, I tell you how to reheat this recipe.

The ketogenic diet, or keto, refers to a way of eating that can be described as low-carb, high-fat, and moderate protein.

Frequently Asked Questions

Why does cauliflower go watery in the oven?

Cauliflower is full of water! While it’s rich in fiber and considered a cruciferous vegetable it can hold a lot of water. That water is released when it’s cooked. If it’s overcooked, even more water comes out. With a simple cauliflower casserole like this, you want that extra soft cauliflower. So, steam the vegetable, then drain it well before adding to your ingredients!

Can I add cream cheese to my cauliflower casserole?

You can if you’d like a super-rich cheese sauce!

  1. I don’t think you have the right measurement for the house Seasoning mix…(1/4 cup).

    1. Yes, that is the correct measurements. The point is to make a big jar, and use it often. It’s a time saving spice blend recipe!
