Ingredients for Cheesy Potato Casserole
The beauty of this recipe lies in its simplicity. You’ll need a few basic ingredients to make this dish:
- 4 medium-sized potatoes, peeled and thinly sliced
- 2 cups shredded cheddar cheese
- 1 cup sour cream
- 1/2 cup milk
- 1 can (10.5 oz) cream of mushroom soup
- 1 tablespoon butter, melted
- 1/2 teaspoon garlic powder
- Salt and pepper to taste
- 1 cup crushed cornflakes (for topping)
- Fresh parsley (optional, for garnish)
These ingredients come together to form a rich, creamy, and cheesy casserole that’s perfect for any time of year. The potatoes absorb the creamy sauce, while the melted cheese binds everything together. The cornflake topping adds a delicious crispy texture that’s irresistible.
Step-by-Step Cheesy Potato Casserole Recipe
This cheesy potato casserole is incredibly easy to prepare. Follow these simple steps for a cheesy, golden brown delight.
Step 1: Prepare the Potatoes
Start by peeling and thinly slicing the potatoes into rounds. You can use a sharp knife or a mandoline slicer for even slices. Place the sliced potatoes into a large bowl of water to prevent browning while you prepare the other ingredients.
To ensure even cooking, try to slice the potatoes uniformly. Thin slices (about 1/8-inch thick) work best as they cook evenly and absorb the sauce nicely.
Step 2: Make the Creamy Sauce
In a separate bowl, combine the sour cream, milk, cream of mushroom soup, melted butter, garlic powder, salt, and pepper. Stir until the mixture is smooth and well combined. This sauce will give the casserole its creamy texture and rich flavor.
If you want a richer sauce, you can use heavy cream instead of milk. You can also swap the cream of mushroom soup with cream of chicken or vegetable soup for different flavors.
Step 3: Layer the Casserole
Grease a 9×13-inch baking dish with a bit of butter or cooking spray. Begin layering the sliced potatoes in the dish, spreading them out evenly. Pour about half of the creamy sauce over the potatoes, then sprinkle one cup of shredded cheddar cheese on top. Repeat the layering with the remaining potatoes, sauce, and cheese.
Be sure to press the layers down lightly to ensure the casserole holds together during baking. If you like, you can add a layer of crispy bacon or sautéed onions for added texture and flavor.
Step 4: Add the Crunchy Topping
For that crispy, golden topping, sprinkle crushed cornflakes over the top of the casserole. This adds a delightful crunch that contrasts beautifully with the creamy potatoes. If you don’t have cornflakes, you can substitute with crushed Ritz crackers or panko breadcrumbs.
For an extra cheesy topping, sprinkle more cheese on top of the cornflakes. The cheese will melt and blend with the crispy topping, creating a perfect crust.
Step 5: Bake the Casserole
Preheat your oven to 350°F (175°C). Cover the casserole with aluminum foil and bake it for 45-50 minutes, or until the potatoes are tender. After that, remove the foil and continue baking for an additional 10-15 minutes to allow the cheese to become bubbly and the topping to crisp up.
If you like a softer casserole, you can bake it for a bit longer with the foil on. For a crunchier topping, uncover the casserole earlier in the baking process.
Step 6: Rest and Serve
Once the casserole is done baking, remove it from the oven and let it rest for about 5-10 minutes. This will allow the flavors to meld together, and it will make it easier to cut. Garnish with fresh parsley if desired, and serve hot!
Resting the casserole also allows the sauce to thicken slightly, making it easier to serve in neat, cohesive slices.
Pro Tips for the Perfect Cheesy Potato Casserole
- Use Russet Potatoes: Russet potatoes work best for this dish because they’re starchy and become tender when baked. You can also use Yukon Gold potatoes for a creamier texture.
- Add Extra Flavor: Feel free to add some extras to the casserole like cooked bacon, sautéed onions, or even a mix of different cheeses such as mozzarella or gouda.
- Don’t Overcrowd: If you’re making a large batch, consider using two smaller casserole dishes to ensure even cooking. This also helps with browning and crisping the top.
How to Store and Reheat Leftovers
If you have any leftovers, don’t worry! This cheesy potato casserole stores well and can be enjoyed the next day.
- Refrigerate: Store the casserole in an airtight container in the fridge for up to 3-4 days. It reheats wonderfully and still tastes great.
- Reheat: To reheat, cover the casserole with foil and place it in a preheated oven at 350°F (175°C) for about 20-25 minutes, until heated through. You can also reheat individual portions in the microwave.
If you’re reheating leftovers, try not to overcook them to avoid drying out the casserole. You can always add a little extra cheese or sour cream to bring back the creaminess.
Ways to Customize Your Cheesy Potato Casserole

The beauty of this dish is that you can easily make it your own by adding or changing a few ingredients. Here are some ideas:
- Meat Lovers: Add crumbled cooked sausage, bacon bits, or ground beef to the layers for a heartier dish.
- Vegetable Option: For a more colorful casserole, consider adding some vegetables such as broccoli, spinach, or bell peppers between the layers. You can also sneak in some grated carrots or zucchini for added nutrition.
- Spicy Twist: Add some diced jalapeños or a dash of hot sauce to the sauce for a spicy kick. You can also sprinkle some chili powder or cayenne pepper on top for extra heat.
- Herb Infusion: Fresh herbs such as thyme, rosemary, or parsley can be sprinkled throughout the casserole to add a fresh, aromatic note.
