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

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)

Cheese and Garnish

  • 1 1/2 cups shredded cheddar cheese
  • Fresh parsley, for garnish

Instructions

  1. Cook the beef and onion: In a large skillet or oven-safe pot over medium heat, brown the ground beef alongside the chopped onion, stirring occasionally until the beef is fully cooked and the onion is soft, about 5-7 minutes. Drain excess fat if necessary.
  2. Season the beef mixture: Add salt, black pepper, and paprika to the cooked beef and stir well to combine the flavors evenly.
  3. Prepare the creamy sauce: In a bowl, mix the cream of mushroom soup, whole milk or heavy cream, and sour cream (if using) until smooth.
  4. Layer the potatoes and beef: In the same pot or transfer to a casserole dish, spread a layer of thinly sliced potatoes evenly over the beef mixture.
  5. Add the creamy sauce: Pour the prepared creamy sauce over the potatoes, ensuring it covers the layers well for even cooking.
  6. Top with cheese: Sprinkle the shredded cheddar cheese evenly over the entire casserole.
  7. Bake the casserole: Preheat the oven to 375°F (190°C). Cover the casserole with foil and bake for 40 minutes. Then remove the foil and bake for an additional 15 minutes or until the potatoes are tender and the cheese is bubbly and golden brown.
  8. Garnish and serve: Remove from the oven and let cool slightly before garnishing with fresh parsley. Serve warm as a hearty main dish.

Notes

  • For best results, use thinly sliced potatoes to ensure they cook through evenly during baking.
  • Sour cream is optional but adds extra creaminess and tang to the sauce.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
  • You can substitute cream of mushroom soup with cream of chicken or celery soup if preferred.
  • To make this dish gluten-free, confirm that the cream of mushroom soup is gluten-free or prepare a homemade sauce.
