Equipment

  • 9x13-inch baking dish
  • Large skillet
  • Large bowl
  • Aluminum Foil
  • Oven

Ingredients
  

  • 1 pound ground beef 80/20 or 85/15 recommended
  • 4 medium potatoes Russets, thinly sliced
  • 1 medium onion diced
  • 2 cups Cheddar cheese shredded, sharp or mild
  • 1 can cream of mushroom soup 10.5 oz
  • 1 cup milk
  • 1 cup sour cream
  • salt to taste
  • pepper to taste
  • 1 teaspoon garlic powder
  • 1 teaspoon paprika

Instructions
 

  • Step 1: Preheat oven to 350°F (175°C). Grease a 9x13-inch baking dish.
  • Step 2: In a large skillet, brown the ground beef over medium heat, breaking it up as it cooks. Drain off any excess fat.
  • Step 3: Add diced onion, garlic powder, salt, and pepper to the skillet with the beef. Cook for 2-3 minutes until the onion softens.
  • Step 4: In a large bowl, combine the cooked beef and onion mixture with the thinly sliced raw potatoes.
  • Step 5: Add sour cream, cream of mushroom soup, and milk to the bowl. Stir in half of the shredded cheddar cheese. Mix everything well to coat the potatoes and beef.
  • Step 6: Pour the mixture evenly into the prepared baking dish.
  • Step 7: Sprinkle the remaining shredded cheese over the top.
  • Step 8: Cover the dish snugly with aluminum foil. Bake for 30 minutes.
  • Step 9: Carefully remove the foil. Return the dish to the oven and bake uncovered for another 15-20 minutes, or until the cheese is bubbly and golden brown.
  • Step 10: Let the casserole rest for 5-10 minutes before serving to allow it to set slightly.

Notes

Tips for Success: Slice potatoes thinly and evenly. Drain fat from ground beef well. Taste and adjust seasoning before baking. Allow casserole to rest 5-10 minutes after baking. You can brown the beef and mix sauce components ahead of time and store separately in the fridge; add 5-10 minutes covered baking time if starting cold.
Substitutions & Additions: Add peas, corn, or diced carrots. Use Monterey Jack, Colby Jack, or a cheese blend instead of cheddar. Swap cream of mushroom soup for cream of chicken or celery. Use thinly sliced Yukon Golds or frozen O'Brien style potatoes (adjusting bake time). Add a pinch of red pepper flakes for spice. Garnish with fresh parsley, chives, crispy fried onions, or crumbled bacon.
Storage: Store cooled leftovers covered in the refrigerator for 3-4 days. Reheat individual servings in the microwave or cover dish with foil and warm in a 300°F oven. Freeze portions for up to 3 months; thaw overnight in the refrigerator before reheating.
