Cheesy Baked Potato Casserole is a comforting, rich dish combining fluffy potatoes with creamy cheese, sour cream, and a crunchy topping. Perfect for family dinners or potlucks, it can easily be made vegetarian by swapping cream of chicken soup with cream of mushroom.

  • Total Time: 45 minutes
  • Yield: 4–6 servings

Ingredients

Scale
  • 6 large baking potatoes (about 3 lbs), peeled and cubed
  • 1 cup sour cream
  • ½ cup unsalted butter, melted
  • 2 cups shredded sharp cheddar cheese, divided
  • ½ cup chopped green onions or chives (optional)
  • 1 (10.5 oz) can cream of chicken soup (or cream of mushroom)
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • Salt and black pepper to taste
  • 1 ½ cups crushed crispy fried onions (e.g., French’s)
  • 6 slices bacon, cooked and crumbled (optional garnish)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch casserole dish.
  2. Cook potatoes in a large pot of salted water until tender, about 10–15 minutes. Drain well.
  3. In a mixing bowl, combine potatoes, sour cream, melted butter, 1 ½ cups cheddar cheese, green onions (if using), cream of chicken soup, garlic powder, onion powder, salt, and pepper. Mix gently.
  4. Transfer mixture to casserole dish and spread evenly.
  5. Sprinkle remaining ½ cup cheddar cheese and crushed crispy fried onions on top.
  6. Bake 25–30 minutes until bubbly and golden. Garnish with crumbled bacon and extra green onions if desired. Serve hot.

Notes

  • Use Yukon gold or red potatoes for a creamier texture, adjusting cooking time as needed.
  • Can be prepared a day ahead; store covered in the refrigerator and add extra baking time when baking cold.
  • Leftovers keep in an airtight container in the fridge for 3–4 days; reheat in oven or microwave.
  • For a vegetarian version, use cream of mushroom soup and omit bacon or use a plant-based alternative.
