How to Make Cheesy Potato Casserole

This cheesy potato casserole is so simple! Since we’re starting off with frozen hash browns, it’s really easy to make the potato mixture. Once that’s ready, you can add the potato chip topping and bake. No hassle, just cheeeeeesy potatoes. 

Here’s a simple overview for this amazing hash brown potato casserole:

  1. Let the frozen hash browns thaw partially before starting. 
  2. Heat butter and oil in a medium skillet, than saute the onions.
  3. Whisk together melted butter, celery and mushroom soups, grated cheese, and sour cream, then add in the sauteed onions and stir.
  4. Mix in the hash browns, pour the potato mixture into the prepared casserole dish, and add the potato chip topping.
  5. Bake for 45-55 minutes at 350°F.

When it’s done, the potato chips will be browned, but make sure they don’t burn. Let the cheesy potato casserole cool for about 5 minutes before serving. Check the recipe card below for more detailed instructions.

Can you make cheesy potato casserole ahead of time?

Yes! I love easy recipes for the holidays, and nothing is easier than something you can make ahead of time! Just follow the recipe as written to prepare the potatoes, but hold off on cooking them or adding the topping. That will be done later on. Once you have the cheesy potato casserole mixture in the baking dish, cover in with plastic wrap and store it in the refrigerator until you’re ready to bake (up to 48 hours).

When it’s time to cook, set the casserole out at room temperature for about 30 minutes ahead of time. This is a great time to preheat the oven and make the potato chip topping. Add it on top of the potatoes and bake at 350°F. Add 5-10 minutes to the cooking time listed in the recipe card if needed.

I love that this is another make ahead side dish you can add to the holiday menu, along with Make Ahead Mashed Potatoes and Make Ahead Turkey Gravy.

  • 2 cups sour cream
  • 2 cups grated sharp cheddar cheese – divided
  • 1 1 lb. 14 oz. package frozen shredded hash browns, partially thawed


  • 2 cups crushed ruffle potato chips
  • ¼ cup unsalted butter melted

  1. Heat oven to 350°F and spray a 9×13 or a 2 quart baking dish with nonstick spray.
