Easy 5-Ingredient Hamburger & Potato Casserole

Preheat the oven to 350°F (175°C).

Cook the ground beef: In a skillet over medium heat, brown the ground beef for 5-7 minutes, breaking it up as it cooks. Drain excess grease and season with salt and pepper. Set aside.

Prepare the potatoes: Peel and thinly slice the potatoes. Layer them at the bottom of a lightly greased 9×13-inch baking dish.

Assemble the casserole: Spread the cooked ground beef over the potato layer. In a bowl, whisk together the cream of mushroom soup and milk, then pour it evenly over the beef and potatoes.

Bake: Cover the dish with foil and bake for 1 hour. Remove the foil, sprinkle cheddar cheese on top, and bake for an additional 15 minutes until the cheese is golden and bubbly.

Rest and serve: Let the casserole sit for 5 minutes before serving.
