How to Make Cheesy Potato Casserole

Making this potato casserole is no sweat at all. After you sauté the onions, essentially all you have to do is mix the other ingredients together, add the topping, and then bake it.

Let’s get started!

Prep: Preheat the oven to 350°F. Grease a 13×9 dish.

Sauté Onions: In a large sauté pan over medium-high heat, melt butter. Add onion and cook until translucent, about 5-7 minutes. Add garlic and cook for 30 seconds. Remove from heat.

Mix Other Ingredients: In a large bowl, combine all remaining ingredients: sour cream, cream of chicken soup, 1/2 cup melted butter, black pepper, shredded hash brown potatoes and shredded cheddar cheese; stir until well blended. Fold in cooked onion mixture. Pour into prepared baking dish.

Add Topping: In a medium sized bowl, combine ritz crackers and melted butter. Sprinkle evenly over the top of the casserole.

Bake: Bake for 40 to 45 minutes, or until bubbly and the top is browned. Serve hot!

Tips for Success

Super easy, right? Here are some tips to help you with this cheesy potato casserole just in case, though.

  • For Using Fresh Potatoes: if you use fresh potatoes, you’ll want to peel them, cut them into cubes, and parboil them before proceeding with the recipe.
  • Make It Ahead: if you hold off on adding the topping, you can refrigerate the uncooked casserole and then bake it with the topping when you’re ready to eat.
  • Add Meat: this can easily be served as a main course if you add in some ham or chicken.

Variation Ideas

Though this casserole is already pretty fantastic, there are a couple of substitutions or add-ins that you may want to consider. Here are some ideas to get you started:

  • Use Potatoes: you can used cubed potatoes instead of hash browns if you want.
  • Crushed Chips vs Crackers: you could crumble some crushed chips on top (like Lays) instead of using Ritz Crackers.
  • Add Bacon: who doesn’t love bacon bits in a casserole?
  • Add Veggies: you could try broccoli, peas, etc.

How to Store and Reheat Leftovers

You can refrigerate this potato casserole in an airtight container for about 2-3 days. You could also freeze it, but I would omit the crushed topping until you’re ready to bake it again.

To reheat these leftovers, pop them in the toaster oven at 350°F for a couple of minutes, or simply put them in the microwave for 30 seconds to a minute.
