Cheesy Potato Casserole is a comforting, creamy dish featuring thinly sliced potatoes layered with onions, sour cream, and melted cheddar cheese, topped with a crunchy buttery crust made from cornflakes or crushed crackers. Perfect for family dinners, holidays, or potlucks.
4–5 large potatoes, peeled and thinly sliced
1 medium onion, finely chopped
2 cups shredded cheddar cheese (or cheddar-mozzarella blend)
1 cup sour cream
1 can cream of chicken soup (or cream of mushroom for vegetarian)
½ cup milk
¼ cup melted butter
Salt and pepper to taste
½ cup grated Parmesan cheese (optional)
1 cup cornflakes or crushed Ritz crackers (for topping)
1–2 tbsp melted butter (for topping)
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
Mix sour cream, cream soup, milk, melted butter, salt, and pepper in a large bowl.
Layer half the potatoes in the dish, then half the onions and cheese.
Pour half the sour cream mixture over the layers. Repeat with remaining potatoes, onions, cheese, and sour cream mixture.
Combine cornflakes or crackers with melted butter and Parmesan if using; sprinkle evenly on top.
Cover with foil; bake 45 minutes. Remove foil and bake 15-20 more minutes until potatoes are tender and topping golden.
Let cool a few minutes before serving.
Mix in green onions or chives for freshness.
Substitute sour cream with Greek yogurt for tanginess.
Use sweet potatoes for a twist.
Try crushed fried onions as topping instead of cornflakes/crackers.
Broil 2-3 minutes at the end for extra crispy topping.
Use gluten-free soup and toppings to keep recipe gluten-free.
