Ingredients

Scale

Beef Mixture

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

Potatoes

  • 2 cups thinly sliced russet or Yukon gold potatoes

Sauces and Dairy

  • 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)
  • 1 1/2 cups shredded cheddar cheese

Garnish

  • Fresh parsley, for garnish

Instructions

  1. Brown the beef and onions: In a large oven-safe skillet or pot, cook the ground beef over medium heat until browned, breaking it apart with a spatula. Add the chopped onion and cook until softened, about 3-4 minutes. Drain excess fat if necessary.
  2. Season and add potatoes: Stir in salt, black pepper, and paprika. Layer the thinly sliced potatoes evenly over the beef and onions in the skillet.
  3. Combine soup and dairy: In a separate bowl, mix together the cream of mushroom soup, whole milk or heavy cream, and sour cream if using. Pour this creamy mixture evenly over the layered potatoes and beef.
  4. Add cheese: Sprinkle the shredded cheddar cheese evenly over the top of the casserole.
  5. Simmer to cook potatoes: Cover the skillet with a lid or foil and cook on low heat on the stovetop for about 30-40 minutes, or until the potatoes are tender when pierced with a fork. Alternatively, transfer the skillet to a preheated 350°F (175°C) oven and bake for 35-45 minutes.
  6. Garnish and serve: Once cooked and bubbly, remove from heat and garnish with fresh parsley. Let it rest for 5 minutes before serving to allow the casserole to set.

Notes

  • Use thinly sliced potatoes for faster and even cooking.
  • Heavy cream will yield a richer casserole compared to whole milk.
  • The sour cream is optional but adds extra creaminess and tang.
  • Covering the pot properly ensures the potatoes steam and become tender.
  • If baking, use an oven-safe skillet or transfer to a baking dish.
  • Leftovers can be refrigerated for up to 3 days and reheated gently.
