Ingredients

Units Scale

Beef Mixture

  • 1 lb ground beef
  • 1 small onion, chopped
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp paprika

Potato Layer

  • 2 cups thinly sliced russet or Yukon gold potatoes

Creamy Sauce

  • 1 can (10.5 oz) cream of mushroom soup
  • 1/2 cup whole milk or heavy cream
  • 1/2 cup sour cream (optional for extra creaminess)

Topping

  • 1 1/2 cups shredded cheddar cheese

Garnish

  • Fresh parsley, for garnish

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to ensure it’s ready for baking the casserole.
  2. Cook Beef and Onions: In a skillet over medium heat, brown the ground beef along with the chopped onion. Season with salt, pepper, and paprika, then drain any excess fat to keep the casserole from becoming greasy.
  3. Prepare Creamy Sauce: In a bowl, combine the cream of mushroom soup, milk (or heavy cream), and sour cream. Stir until smooth and well blended.
  4. Layer Beef: Spread the cooked, seasoned ground beef mixture evenly in the bottom of a greased 9×13-inch baking dish.
  5. Add Potato Layer: Arrange the thinly sliced potatoes evenly over the layer of beef to ensure even cooking.
  6. Pour Sauce: Pour the creamy mushroom mixture over the potatoes, spreading with a spatula to cover all the slices evenly.
  7. Add Cheese Topping: Sprinkle the shredded cheddar cheese uniformly over the top of the casserole.
  8. Cover and Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes, allowing the potatoes to cook through and flavors to meld.
  9. Uncover and Finish Baking: Remove the foil and continue baking for an additional 15 minutes, or until the cheese topping is golden brown and bubbly.
  10. Rest and Serve: Let the casserole rest for 5 to 10 minutes before serving to set. Garnish with fresh parsley for a pop of color and added freshness.

Notes

  • Slice potatoes thinly, about 1/8 inch thick, to ensure even and thorough cooking in the casserole.
  • Store leftovers in the refrigerator for up to 4 days or freeze for up to 2 months for later enjoyment.
