Cheesy Potato Ingredients

While the obvious ingredient is potatoes we add lots of cheddar cheese, sour cream, butter, soup, and green onions finish out this easy dish.

You can vary these ingredients to suit your taste or use what you have on hand.

  • Cheese: I find that cheddar cheese produces the best sauce with the most flavor, especially if you use extra-sharp but a nice swiss or your fave cheese will work just fine!
  • Potatoes: Almost any kind of potatoes will work for this recipe.
    • In a hurry? Use country style hash browned potatoes in place of boiling your own potatoes.
    • Choose thin skinned potatoes (like Yukon gold or red potatoes) and skip the peeling
  • Canned Soup: Use any kind of condensed “cream of” canned soup in this recipe. I love using homemade condensed mushroom soup to control the salt.

If you want to make your cheesy potato bake more of a one-pot meal, then go ahead and add a cup or two of diced ham or some poached chicken breasts (or leftover roast chicken). Even ground beef would be great in this casserole!

How to Make Cheesy Potatoes (with real potatoes)

This casserole recipe is a simple variation of scalloped potatoes, but with diced potatoes and requires less prep thanks to an easy-to-make sauce. Here’s how easy it is to make cheesy potatoes in the oven:

  1. Boil the diced potatoes until tender.
  2. Melt the butter and mix in the remaining ingredients. Save some cheese to sprinkle on top.
  3. Combine all the ingredients together, including the cooked potatoes, and transfer to a greased casserole dish.
  4. Top with the remainder of the cheese and bake until bubbling and browned.

Don’t cover these cheesy potatoes while baking. You want the top to get golden brown.

Not ready to bake it yet? Cheesy potatoes will keep in the refrigerator for 2-3 days before baking. So make this dish extra easy by taking care of all the prep work the day before! Just pop them in the oven following the recipe and you are ready to enjoy.

Can You Freeze Cheesy Potato Casserole?

Cheesy potatoes come out of the oven tender and delicious! You can make and bake this casserole ahead of time and freeze it as well. Or, freeze the leftovers, if there are any!

Let this dish thaw before baking at 400F for about an hour, or until piping hot and the cheese is nicely browned.
