Start by preheating your oven to 375°F. Grab a 9x13 inch baking dish and give it a good coating of cooking spray.

In a large skillet, brown the ground beef with the diced onions and garlic until the meat is no longer pink. Drain off any excess fat, then season with salt and pepper.
03 -
Create your first layer by arranging sliced potatoes across the bottom of your prepared baking dish. Top this with half of your seasoned ground beef mixture.
04 -
Whisk together the cream of mushroom soup, cream of chicken soup, regular milk, and evaporated milk until smooth. Pour half of this creamy mixture over your beef layer and sprinkle with half the cheese.
05 -
Repeat the layers once more, finishing with the remaining cheese on top for that perfect golden crust.
06 -
Cover the dish with foil, making sure to tent it slightly so it doesn't stick to the cheese. Bake for 1 hour, then remove the foil and bake for another 30 minutes until bubbly and golden.

Let your casserole rest for 10 minutes on a wire rack before serving. This helps everything set up nicely for perfect portions.
