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.

Ingredients

45 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)

12 tbsp melted butter (for topping)

Instructions

  • 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.

Notes

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.
