Easy Cheesy Hash Brown Casserole Recipe

This casserole is for the potato lovin’ people at your table. I’ve served this hash brown casserole for breakfast, brunch and as a side dish for dinner. While hash brown casseroles certainly aren’t a new phenomenon, I wanted to share my recipe inspired by that potluck favorite that’s rotated among church and office dinners for as long as I can remember. You know the one, they’re sometimes called funeral potatoes, topped with buttery cornflakes. There’s nothing wrong with that version at all, but I have always topped my casserole with crushed potato chips. I mean, why not? Just like in recipe for Au Gratin Ranch Potatoes, it’s the crowning touch.

How to Make the Best Cheesy Hash Brown Potato Casserole Recipe

  • Ingredients you’ll need to make this recipe for hash brown casserole: Shredded refrigerated hash browns, sour cream, butter, cream of celery soup, half and half, Parmesan cheese, egg, black pepper, salt, granulated garlic or garlic powder, shredded Colby or cheddar cheese and crushed potato chips for the topping.
  • Kitchen tools you’ll need: Large bowl, measuring cups and spoons, cheese grater, sharp knife and cutting board and 13 x 9 inch baking dish.
  • This recipe can easily be halved for a smaller version.
  • If you prefer, you can substitute thawed frozen shredded hash browns in place of refrigerated hash browns.
  • Likewise, you can use raw shredded potatoes that you’ve made yourself. When doing so, I find it necessary to nuke them in the microwave for a few minutes so that they are partially cooked before combining with the remaining ingredients. You’ll need around 8-10 cups of freshly shredded, par cooked potatoes.
  • This is one dish that I actually prefer making with Colby cheese. If you think you’d like to use cheddar cheese or a different flavor, feel free to adapt.
  • Can you make hash brown casserole the night before? This hash brown potato casserole can be fully assembled ahead of time, up to one day in advance. Spread it into the baking dish, cover with plastic wrap and chill overnight in the refrigerator. Allow it to sit on the counter for 20 minutes or so, to warm just a bit before baking. Add more baking time, as needed.
  • You can reheat single servings of  leftover hash brown casserole in the microwave. You can also reheat it in an oven safe dish in a 350°F oven for 20 minutes or just until heated through. Lay foil on top to prevent overbrowning.
  • You can freeze baked hash brown casserole for up to 1 month. Thaw it in the refrigerator overnight then reheat in a 350°F oven until fully heated through.
