Ingredients

• 1 1/2 lbs ground beef
• 1 yellow onion, finely diced
• 4 lbs russet potatoes, peeled and sliced 1/4-inch thin
• 2 cups cheddar cheese, grated
• 1 (10.75 oz) can condensed Cheddar soup
• 1 (12 oz) can evaporated milk
• 1/2 cup milk
• 1/2 teaspoon garlic powder
• Kosher salt and freshly ground black pepper, to taste

Instructions

1. Preheat the Oven: Preheat your oven to 350°F. Spray a 9×13-inch baking dish with nonstick spray and set aside.
2. Cook the Beef and Onion: In a large skillet over medium-high heat, add the ground beef and diced onion. Season with salt and pepper. Cook until the beef is no longer pink, breaking it up with a wooden spoon as it cooks. Drain any excess fat and set the beef mixture aside.
3. Layer the Potatoes and Beef: Arrange a single layer of the peeled and sliced potatoes at the bottom of the prepared baking dish. Season with a sprinkle of salt and pepper. Top with 1/4 of the cooked beef mixture and 1/4 of the grated cheddar cheese. Repeat these layers three more times, ending with a layer of cheese on top.
4. Prepare the Cheese Sauce: In a small bowl, whisk together the condensed Cheddar soup, evaporated milk, milk, and garlic powder until smooth and well combined.
5. Add the Cheese Sauce: Pour the cheese sauce evenly over the layered ingredients in the baking dish, ensuring it covers the top layer completely.
6. Bake the Casserole: Cover the baking dish tightly with aluminum foil. Place it in the preheated oven and bake for 60 minutes. After 60 minutes, remove the foil and continue baking for an additional 15 minutes, or until the top is golden brown and bubbly.
7. Serve and Enjoy: Remove the casserole from the oven and let it sit for a few minutes before serving. Enjoy the cheesy, comforting flavors of this hearty dish!

Tips and Variations

• Vegetable Add-ins: Add some diced bell peppers or mushrooms to the beef mixture for an extra layer of flavor and nutrition.
• Spice it Up: For a bit of heat, sprinkle some red pepper flakes or add a diced jalapeño to the beef mixture.
• Creamier Sauce: For an even richer sauce, substitute half of the milk with heavy cream.
• Cheese Variety: Mix in other types of cheese like mozzarella, Monterey Jack, or Colby for a different flavor profile.
