In a large skillet over medium heat, cook ground beef with diced onions and garlic until beef is browned and no longer pink. Drain any excess grease and season with salt and pepper.

Layer thinly sliced potatoes across the bottom of the prepared baking dish. Add half of the cooked beef mixture over the potatoes.

Repeat with another layer of potatoes, remaining beef, and the rest of the soup mixture. Finish with the remaining cheese on top.

Remove foil and continue baking for 30 minutes until the top is golden and bubbly.
