    I love potatoes, and I love to add anything possible to them. With this casserole, I added EVERYTHING to them. Thank me later!

    Cheesy Potato Casserole

    This was inspired by my other mashed potato casserole recipe on this site and pairs well with this amazing air fryer fried chicken recipe.

    Ingredients

    This recipe is exploding with flavor, but it only uses simple ingredients to make it.

    • Frozen shredded hashbrowns
    • Cream of chicken soup
    • Finely shredded pepper jack cheese
    • Heavy cream
    • Unsalted melted butter
    • Sour cream
    • Grated parmesan cheese, divided
    • Onion powder
    • Garlic powder
    • Mustard powder
    • Salt and pepper to taste
    • Fried onions
    • Ritz crackers
    • Cooked, chopped bacon
    • Paprika
    • Chopped fresh parsley

    See the recipe card at the end of the post for quantities.

    Instructions

    Like any good casserole, this one is easy to make! It only takes a few steps.

    Step 1: Mix the Casserole Ingredients

    Add the frozen hashbrowns, chicken soup, pepper jack cheese, ¼ cup of the parmesan cheese, heavy cream, melted butter, sour cream, onion powder, garlic powder, mustard powder, and salt and pepper to a large mixing bowl. Stir well to combine.

    Step 2: Add to the Baking Dish

    Add the casserole mixture to a lightly greased or sprayed 9x13 casserole dish.

    Step 3: Mix the Topping Ingredients

    Add the fried onions, Ritz cracker crumbs, bacon, remaining parmesan cheese, and paprika to a medium mixing bowl and mix well.

    Step 4: Bake

    Sprinkle the topping over the casserole. Then, bake it uncovered for 45 minutes at 400 degrees.

    Step 5: Serve

    Remove the casserole from the oven and let it cool slightly. Then sprinkle it with chopped parsley and serve.

    Hint: The easiest way to crush the Ritz is to place them in a resealable bag and pound them with a rolling pin.

    Substitutions

    Don't have the correct ingredients on hand or want to change something up? Here are some helpful tips for you to change this cheesy potato casserole.

    • Milk - If you don't have heavy cream, you can use milk.
    • Real Bacon Bits - If you don't have bacon to cook and crumble, you can use pre-packaged real bacon bits.
    • Greek Yogurt - If you don't have sour cream, full-fat Greek yogurt tastes almost the same.

    Want to personalize this pepper jack potato casserole recipe? Here are some of my tried and true tips for changing up this recipe.

    • Spicy - Add red pepper flakes for a spicy kick.

    FAQ

    Do you have questions about this pepper jack potato casserole? Here are some of the most commonly asked questions about cheesy potato casserole.

    How do I reheat potato casserole?

    Depending on the size of the piece you are reheating – cook on 50% power for 2 minutes then give a final 30 second heat on full power. This should ensure the center is warm enough.

    Can I freeze this casserole?

    I don't recommend it. Freezing will change the texture of almost everything in this recipe.

    Do you thaw hash browns for a casserole?

    It is not needed in this recipe, as the extra moisture is actually used and mixes well.

    What is in pepper jack cheese?

    It’s a type of Monterey jack cheese that is stuffed with peppers and seasoning to add plenty of flavor.
