Preheat oven to 400°F. In a large skillet, cook ground beef until browned. Add onion and garlic, cooking until softened.
Stir in tomatoes, black beans, corn, chili powder, and cumin. Season with salt and pepper.
In a large baking dish, layer half the potatoes, half the beef mixture, and half the cheese. Repeat layers.
Cover with foil and bake for 45 minutes. Remove foil and bake an additional 15 minutes until potatoes are tender and cheese is melted.
