What You’ll Need

Here’s a quick overview of what you’ll need to make hash brown casserole. Be sure to scroll down to the recipe card for specific amounts:

  • Frozen Hash Brown Potatoes – These are found in the freeze section of the grocery store.
  • Sauce – When you are making the creamy sauce for this recipe, you are using the cream of chicken soup, sour cream, and mayo. These ingredients come together for a delicious creamy sauce. In a pinch, you can use cream of mushroom soup, but this does give the casserole a different flavor.
  • Cheddar Cheese – Cheddar cheese is my favorite choice but you can use whatever shredded cheese you like.
  • Corn Flakes Cereal – Make sure you are using corn flakes and not frosted flakes. Frosted flakes are sweetened and this is not what you want in your hashbrown casserole.

How to Make Hashbrown Casserole

Combine the Ingredients

Set the oven to 325 degrees and use Pam cooking spray to lightly grease a 13×9-inch baking dish. Add the hashbrowns, cheese, soup, sour cream, mayonnaise, and seasonings into a large bowl and combine until fully incorporated.

Can I Make this Casserole the Day Before?

Yes, this hashbrown casserole can be made ahead if desired. You can prepare all of your ingredients and store the baking dish in the fridge or freezer until you are ready to bake it.

How to Store and Reheat Extras

  • Fridge: Let your casserole cool and then transfer it to an airtight container or cover it tightly with saran wrap. Store in the fridge for up to 4 days.
  • Freezer: Place the casserole in an airtight container and store in the freezer for up to 3 months. Thaw overnight in the fridge before reheating.

You can reheat individual servings in the microwave for a couple of minutes until warmed through. Or you can reheat the entire casserole in an oven preheated to 350F.

The amount of time required to reheat the casserole will depend upon how much food you are reheating at once. If you froze the casserole before baking it, then thaw it overnight in the fridge and bake as directed in the recipe.
