A hearty, budget-friendly casserole featuring layers of seasoned ground beef, thin-sliced potatoes, onions, and a creamy mushroom sauce, topped with melted cheddar cheese.
1 lb ground beef
2–3 russet potatoes, thinly sliced
1 medium onion, thinly sliced
1 can (10.5 oz) cream of mushroom soup
½ cup milk
1½ cups shredded cheddar cheese
1 tsp salt
½ tsp black pepper
½ tsp garlic powder
Optional: sliced mushrooms, bell peppers, paprika
Preheat oven to 375°F. Lightly grease a 9×13″ casserole dish.
Brown ground beef in a skillet with salt, pepper, and garlic powder. Drain fat.
In a bowl, mix cream of mushroom soup with milk.
Layer half the potatoes, onions, beef, and soup mixture. Repeat with remaining ingredients.
Cover with foil and bake for 60 minutes.
Remove foil, sprinkle cheese on top, and bake 15–20 minutes more.
Let rest 10 minutes before serving.
Slice potatoes very thin for even cooking.
Swap soup for homemade white sauce if desired.
Add extra veggies between layers for variety.
