Step-by-Step Instructions
1. Prep the Potatoes
Wash and slice the potatoes into ⅛-inch rounds.
Place them in cold water to prevent browning while you prepare the other ingredients.
2. Cook the Ground Beef
In a large skillet over medium-high heat, cook the ground beef with diced onion and garlic.
Break up the meat as it cooks and continue sautéing until browned.
Drain off any excess fat and set aside.
3. Mix the Sauce
In a medium bowl, whisk together the cream of mushroom soup, half and half, onion powder, salt, and pepper until smooth and creamy.
4. Assemble the Casserole
Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish.
Layer the ingredients in this order:
-
⅓ of the potatoes
-
⅓ of the beef mixture
-
¾ cup cheese
-
⅓ of the soup mixture
Repeat the layers twice more.
Finish with the remaining potatoes, beef, sauce, and top with 1½ cups of cheese.
5. Bake
Cover the dish tightly with foil and bake for 1 hour and 10 minutes.
Remove the foil and bake for another 20 minutes, or until the top is golden and bubbly.
6. Rest and Serve
Let the casserole rest for 15 minutes before serving.
This helps it set and makes slicing easier. Serve warm and enjoy every creamy, cheesy bite.
Tips for the Best Casserole
-
Soak the potatoes: Keeps them from browning and helps them cook evenly.
-
Use freshly shredded cheese: It melts smoother and tastes richer than pre-shredded.
-
Don’t skip the rest time: It helps the layers hold together beautifully.
-
Add veggies: Try mushrooms, bell peppers, or spinach for extra flavor and nutrition.
-
Make ahead: Assemble the casserole the night before and refrigerate. Bake when ready to serve.
