Let’s get started.

How to Make Hash Brown Casserole with Sour Cream

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

Cream of Mushroom Soup — if you’ve ever seen a recipe for funeral potatoes, you’ll notice it calls for cream of chicken soup. Use whatever cream soup you have on hand! I don’t think you can go wrong here! Cream of celery soup, creamy of cheddar soup, or anything of the sort. Yum!!

Frozen Potatoes — Grab some Southern-Style Hashbrowns from your grocer’s freezer section. These are the cubes of brown potatoes! The diced potatoes. Sometimes they even have onions and peppers in the mix. If you can only find shredded hash browns, those will work fine too! You’ll get a more Cracker Barrel Hashbrown Casserole style cheesy casserole, but you really cannot go wrong with this recipe! 

​Pro Tip: Keep a bag of frozen hash browns in your fridge at all times. This recipe mixes up in less than 10 minutes, and it’s an easy side dish the entire family will love! You can serve it as a dinner side dish, or the perfect breakfast casserole.

Sour Cream — Sour cream is one of the best ways to make a delicious casserole. It creates a creamy sauce with the cheddar cheese and cream of mushroom soup. And, potatoes and sour cream are synonymous!

Cheese — Shredded cheddar cheese is super yummy in this comforting side dish recipe, but feel free to use different cheeses. It’s the perfect way to use up the leftover bags of cheese in your fridge, too! 

Melted Butter — Cheesy hashbrown casserole recipe isn’t complete without half a cup of butter that’s been melted. 

You’ll need something for the top of the casserole, and in these pictures, I used a combination of crushed potato chips, fried onions, and extra cheese. Some people use crushed cornflakes, which makes for a super crunchy topping! 

Mixing Up the Potato Casserole

This is a dump-it-in, mix-it-up-and-bake-it kind of casserole dish. I prefer to mix everything up in a large bowl, but people do just mix it up in their baking dish, which makes for effortless cleanup!

Take your cream of mushroom soup, sour cream, and cheese and mix them up so they’re evenly combined. 

Dump in your potatoes — I like to thaw mine out the night before, but straight from the freezer works just fine.

Gently combine hash browns and the cheesy mixture together. I like to fold everything in since the potatoes are delicate, especially if they’re thawed. 

At this point, you may have noticed we haven’t added any seasoning. Mainly because the cream of mushroom soup is salty, and it’s best to add extra after it’s cooked, right at the table.

You can add a generous grind of black pepper! Or some garlic powder and onion powder. Fresh sliced green onions would be nice, too, and add a little color.

Once your simple ingredients are mixed well, dump this into a casserole dish that’s been sprayed with cooking spray. 

​Smooth it out, and move on to making your crunchy casserole topping.

If you are making this casserole ahead of time, which you can do up to 3 days in advance, cover it with plastic wrap and store it in the fridge.

Crunch Topping for Hash Brown Casserole Recipe with Sour Cream

Here’s where you can get fancy, or plain, whatever you want!

I mixed crushed potato chips, fried onions, and extra shredded cheese to make my topping.

However, if you want to top your comfort food dish, do it!! It’s one of the best things about this recipe, and the measurements are in the full printable recipe below.
