Baked Potato Casserole – a cheesy potato casserole that is great for entertaining, potlucks, or even busy weeknights. Comforting, delicious, and a family favorite.
Cheesy potatoes are a classic for lots of families around the holidays. There is just something about the gooey, cheesy goodness that wins everyone over. My family goes crazy for it with Tangerine Glazed Ham.
Growing up, cheesy potato casserole was not a thing in my family. It wasn’t until I met my husband and his mom made them, then they became a staple for us. Now we make them every year, and the rest of my family makes them as well.

Cheesy Potato Casserole
This baked potato casserole uses a little help from the store with frozen potatoes. But you can definitely dice your own if you want. I can never get them all the same size, so I like the precut ones for stuff like this. And if you want to free up some oven space try the Crockpot Hashbrown Casserole version of this recipe.

- Frozen Hash Browns
- Butter
- Sour Cream
- Cream of Chicken Soup
- Onion
- Garlic Salt
- Black Pepper
- Cheddar Cheese
- Cornflakes
My mother in-law always makes her with the shredded hash browns, but here I went with the diced potatoes. The texture is a little different; I think they hold up a little better to the baking. But they both work really well, so it is personal preference.

How To Make Baked Potato Casserole
- In a large bowl mix together hashbrowns, 1/2 cup melted butter, sour cream, cream of chicken soup, cheddar cheese, onion, garlic salt and black pepper. Mix until everything is well combined.
- Pour into prepared baking dish.
- Sprinkle the cornflakes over the potatoes. Drizzle with the remaining 1/4 cup of butter.
- Bake for 40-45 minutes until hot and bubbly.
The cornflake topping is an optional topping that adds just a little bit of texture. You can mix up what you use as well! Potato Chips and Ritz Crackers are common alternatives. So use whatever you have and like to give it that salty crunch.

Can I Make Ahead Of Time
Absolutely! This is a great recipe to assemble and have ready for you. If you are using the cornflake topping, it is best to add that right before putting in the oven. But you can mix everything else together and keep covered in the fridge for up to 2 days before baking.
Can You Freeze Baked Potato Casserole
Yes! This is one of those dishes that freezes really well. Once it is completely cooled you can store in an airtight container for up to 3 months. Let it thaw in the fridge overnight before reheating. I like to heat at a slightly lower temperature (325º F), so that it helps the sour cream and cream soup to stay together.
