Ingredients You’ll Need
Gathering the right ingredients is half the magic here. Each element in this Cheesy Potato Casserole Recipe plays a crucial role in creating the perfect balance of flavors and textures — from the hearty potatoes to the sharpness of cheddar and the crispy topping that seals the deal.
- 4 large russet potatoes, peeled and diced: They give the casserole its soft, comforting base with a mild flavor that soaks up every bit of cheesy goodness.
- 2 cups shredded sharp cheddar cheese: Sharp cheddar adds the perfect kick and creamy meltiness that elevates the dish beyond ordinary.
- 1 cup sour cream: This adds a tangy creaminess that lightens and enriches the sauce beautifully.
- 1/2 cup mayonnaise: Mayonnaise contributes moisture and a smooth texture that helps bind everything together.
- 1/2 cup milk: Milk thins out the sauce just enough for a silky consistency without losing its richness.
- 1/4 cup butter, melted: Butter brings a luscious, rich flavor essential for that decadent mouthfeel everyone loves.
- 1/2 tsp garlic powder: Adds a subtle depth and warmth to the flavor without overpowering.
- 1/2 tsp onion powder: Brings a gentle onion kick that blends seamlessly with the garlic.
- 1 tsp salt: Essential to enhance all the flavors and bring harmony to the dish.
- 1/2 tsp black pepper: Adds a mild spice note that balances the creamy elements perfectly.
- 1 cup crushed cornflakes or breadcrumbs (for topping): This topping provides a satisfyingly crunchy contrast to the creamy potatoes.
- 2 tbsp butter (melted, for topping): Butter coats the topping to ensure it crisps up golden and irresistible.
- Chopped green onions or parsley for garnish (optional): Adds a fresh pop of color and flavor to finish the dish beautifully.
How to Make Cheesy Potato Casserole Recipe
Step 1: Prepare the Potatoes
Start by boiling your diced russet potatoes until they are fork-tender, usually about 10 to 12 minutes. This ensures they’re soft enough to melt in your mouth but still hold their shape when baked. Drain them well and set aside to cool slightly, so they don’t turn mushy when mixed with the sauce.
Step 2: Make the Sauce
In a large bowl, combine the shredded sharp cheddar, sour cream, mayonnaise, milk, and melted butter. Season the mix with garlic powder, onion powder, salt, and black pepper. Give everything a good stir until it’s smooth and creamy. This sauce is the heart of the casserole, packing every bite with rich, tangy, and savory flavor.
Step 3: Combine Potatoes and Sauce
Gently fold the cooked potatoes into the cheesy sauce. Take your time here; you want every potato piece generously coated but still holding together. This step is where the magic truly starts—the potatoes soak up all that creamy goodness, turning into a luscious filling.
Step 4: Assemble the Casserole
Transfer the potato mixture into a greased 9×13-inch baking dish. Spread it out evenly to ensure consistent baking and that each bite will have that perfect balance of creamy and cheesy goodness.
Step 5: Prepare the Topping
Mix the crushed cornflakes or breadcrumbs with melted butter in a small bowl until combined. This topping will add a gorgeous golden crunch that contrasts beautifully with the soft casserole underneath. Sprinkle it evenly on top of the potato mixture.
Step 6: Bake
Pop the casserole into a preheated oven at 350°F (175°C) and bake for 30 to 35 minutes. You’ll want to look for a bubbly, golden-brown top — that’s the sign your Cheesy Potato Casserole Recipe has reached pure perfection.
Step 7: Serve & Enjoy
Once baked, feel free to garnish with freshly chopped green onions or parsley. This final touch not only adds a splash of color but also a mild freshness that completes the dish. Serve it warm and watch everyone dig in happily!

Garnishes
A sprinkle of chopped green onions or fresh parsley adds a lovely visual pop and a touch of brightness against all that creamy, cheesy richness. Besides the herbs, a light dusting of paprika or crumbled crispy bacon can also elevate it to a feast fit for any occasion.
Side Dishes
This casserole pairs beautifully with fresh, crisp salads or roasted vegetables to balance the heaviness with some crunch and freshness. Serve alongside roasted chicken, grilled steak, or even a simple green bean almondine for a complete, satisfying meal.
Creative Ways to Present
Try serving individual portions in ramekins for an elegant presentation at dinner parties, or layer the casserole in a clear glass baking dish to show off the rich layers of cheesy potatoes and crunchy topping. Adding a drizzle of sour cream or hot sauce on the side can also personalize every bite.
Make Ahead and Storage
Storing Leftovers
Place any leftover casserole in an airtight container and store it in the refrigerator for up to 3 days. The flavors meld even more beautifully when reheated, making it perfect for next-day lunches or dinners.
Freezing
This Cheesy Potato Casserole Recipe freezes wonderfully. After assembling (but before baking), cover tightly with foil and freeze for up to 3 months. When ready, bake straight from frozen — just add extra baking time so it heats through completely.
Reheating
Reheat leftovers in a 350°F oven until warmed through and the top is crisp again, usually 20 to 25 minutes. You can also microwave single servings, but the oven helps maintain that lovely crispy topping we all love.
FAQs
Can I use different types of cheese in this casserole?
Absolutely! While sharp cheddar is classic, feel free to mix in mozzarella, Monterey Jack, or even pepper jack for a bit of a spicy twist. Just be sure the cheeses melt well for that perfect creamy texture.
Is it okay to use frozen instead of fresh potatoes?
Fresh russet potatoes work best to hold shape and texture, but if pressed for time, thawed frozen diced potatoes can be used. Just be careful not to overcook so the casserole doesn’t get too mushy.
Can I make this casserole dairy-free or vegan?
The dish relies heavily on dairy for flavor and texture, but you can substitute with plant-based sour cream, vegan cheese shreds, and non-dairy milk alternatives. It won’t be quite the same, but still delicious in its own right!
What can I use instead of cornflakes for the topping?
Breadcrumbs are the perfect alternative for that crunchy topping. You could also try crushed pretzels, panko, or even chopped nuts for a fun twist.
How do I know when the casserole is done baking?
Look for a bubbly surface with a golden-brown, crispy topping. The edges should be set and not jiggly. If you poke it with a fork, you want the potatoes underneath to feel tender but still hold shape.
