Preheat the Oven
Set your oven to 350°F (175°C). This allows the casserole to bake evenly and ensures the ingredients meld together beautifully.
Prepare the Potatoes
Wash, peel, and slice the potatoes into thin, round slices, about 1/8-inch thick. Consistency is key here, so the potatoes cook at the same rate. Set them aside.
Cook the Ground Beef
In a large skillet over medium heat, brown the ground beef until it’s no longer pink. Break it up into small crumbles as it cooks, and add the diced onions. Cook for another 2-3 minutes until the onions are softened. Drain any excess grease and season with salt, pepper, and any optional spices or herbs.
Prepare the Creamy Sauce
In a medium bowl, mix together the can of cream of mushroom soup and milk until smooth. This mixture will help keep the casserole moist and creamy as it bakes.
Layer the Ingredients
Grease a 9×13-inch baking dish lightly with cooking spray or butter. Start by layering half of the sliced potatoes on the bottom of the dish. Sprinkle a bit of salt and pepper over the potatoes. Add half of the cooked ground beef mixture on top of the potatoes, followed by half of the soup mixture. Repeat with another layer of potatoes, ground beef, and soup.
Add Cheese on Top
Spread the shredded cheddar cheese evenly over the top layer. This will create a delicious golden, bubbly crust as it bakes.
Bake the Casserole
Cover the baking dish with aluminum foil and bake in the preheated oven for 1 hour. After an hour, remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the cheese is melted and slightly browned.
Serve and Enjoy
Let the casserole cool for a few minutes before serving. This dish is great as it is, but you can also garnish with fresh parsley, chives, or green onions for added flavor and a pop of color.
Tips for Success:
Thinly Slice the Potatoes: Thin, even slices help the potatoes cook evenly. Using a mandoline slicer can ensure uniform thickness and reduce prep time.
Add More Veggies: For a boost in flavor and nutrients, you can add veggies like bell peppers, mushrooms, or carrots to the ground beef mixture.
Try Different Cheeses: While cheddar is a classic choice, mozzarella, Monterey Jack, or even pepper jack can add a new twist.
Make Ahead: You can prepare the casserole the night before, cover it tightly, and refrigerate. When you’re ready to bake, let it sit at room temperature for about 15 minutes, then bake as directed.
