Method
Preparation
- Preheat the oven to 350°F (175°C).
- In a large skillet, cook the ground beef and diced onion over medium heat until browned. Drain excess fat.
- In a bowl, mix together the cream of mushroom soup and milk, seasoning with salt and pepper.
Assembly
- In a greased casserole dish, layer half of the sliced potatoes, followed by half of the cooked beef mixture, and sprinkle half of the cheese.
- Pour half of the soup mixture over the layers. Repeat the layers with the remaining potatoes, beef, cheese, and soup mixture.
- If desired, sprinkle breadcrumbs on top for added crunch.
Baking
- Cover with foil and bake for 45 minutes. Remove foil and bake for an additional 15 minutes, until cheese is bubbly and potatoes are tender.
- Let cool slightly before serving.
Notes
Slice potatoes thin (about 1/8–1/4 inch) for faster cooking. Consider par-cooking potato slices in boiling water for 5 minutes for quicker baking. Drain the beef well to avoid a greasy casserole. Let the casserole rest for 10 minutes after baking to set and slice cleanly. Optional variations include swapping the cream of mushroom soup for cream of chicken or celery, adding veggies like mushrooms or bell peppers, or using ground turkey or shredded cooked chicken.
