Ingredients

Scale
  • 1.5 lbs russet potatoes, peeled and thinly sliced (about 1/8-inch thick)
  • 1 lb lean ground beef (85/15 or 90/10)
  • 1 medium yellow onion, diced
  • 3 cloves garlic, minced
  • 1 (10.5 oz) can condensed cream of mushroom soup (or cream of chicken)
  • 1 cup beef broth
  • 1 cup sour cream
  • 2 cups shredded cheddar cheese, divided
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon dried thyme
  • Salt and black pepper to taste
  • 1 tablespoon olive oil
  • Fresh parsley or chives for garnish (optional)

Instructions

  1. Preheat oven to 375°F (190°C). Peel and thinly slice potatoes. Rinse slices in cold water and pat very dry with a clean kitchen towel.
  2. Heat olive oil in a large skillet over medium-high heat. Add diced onion and cook for 3-4 minutes until softened. Add ground beef, breaking it up, and cook until no pink remains.
  3. Stir in minced garlic, smoked paprika, thyme, salt, and pepper. Cook for 1 minute until fragrant.
  4. Reduce heat to low. Add condensed soup, beef broth, and sour cream to the skillet. Stir until smooth and simmer for 2-3 minutes. Remove from heat and stir in 1 cup of shredded cheddar until melted.
  5. Spread about 1/2 cup of the beef sauce in the bottom of a 9×13 inch baking dish. Arrange half the potato slices in an even, slightly overlapping layer. Pour half the remaining sauce over the potatoes.
  6. Repeat with the final layer of potatoes and the rest of the sauce. Cover the dish tightly with aluminum foil.
  7. Bake, covered, for 40 minutes. Carefully remove foil, sprinkle the remaining 1 cup of cheddar cheese over the top, and bake uncovered for 10-15 more minutes until cheese is bubbly and golden.
  8. Let the casserole rest for 10 minutes before serving. Garnish with fresh parsley or chives if desired.

Notes

For best results, ensure potato slices are patted dry to prevent a watery sauce. Letting the casserole rest before serving allows the layers to set for neat slices. This dish can be assembled a day ahead and refrigerated before baking, or frozen for up to 3 months (thaw in fridge before baking).
