Ingredients
Here’s what you’ll need to make this delicious casserole:
-
1 lb (450g) ground beef
-
4–5 medium potatoes, thinly sliced
-
1 small onion, finely chopped
-
2 cloves garlic, minced
-
2 cups shredded cheddar cheese
-
1 ½ cups milk
-
1 cup heavy cream
-
2 tablespoons butter
-
2 tablespoons all-purpose flour
-
1 teaspoon salt (or to taste)
-
½ teaspoon black pepper
-
½ teaspoon paprika
-
Optional: 1 cup frozen peas or corn
Instructions
Step 1: Prepare the Oven and Dish
Preheat your oven to 180°C (350°F). Lightly grease a 9×13-inch baking dish and set it aside.
Step 2: Cook the Ground Beef
In a large skillet over medium heat, cook the ground beef until browned. Add the chopped onion and cook until softened, about 3–4 minutes. Stir in the garlic and cook for another minute. Season with salt, pepper, and paprika. Drain excess fat if needed and set aside.
Step 3: Make the Creamy Cheese Sauce
In a saucepan, melt the butter over medium heat. Stir in the flour and cook for about 1 minute to form a roux. Gradually whisk in the milk and cream, stirring constantly to prevent lumps. Continue cooking until the mixture thickens.
Remove from heat and stir in 1 ½ cups of the shredded cheese until melted and smooth. Adjust seasoning if needed.
Step 4: Layer the Casserole
Arrange a layer of sliced potatoes at the bottom of the prepared baking dish. Add a portion of the cooked beef mixture, then pour some of the cheese sauce over it. Repeat the layers until all ingredients are used, finishing with a generous layer of sauce on top.
Step 5: Add Final Cheese Layer
Sprinkle the remaining shredded cheese evenly over the top.
Step 6: Bake
Cover the dish with foil and bake for 45 minutes. Then remove the foil and bake for an additional 20–25 minutes, or until the potatoes are tender and the top is golden and bubbly.
Step 7: Rest and Serve
Allow the casserole to rest for 10 minutes before serving. This helps the layers set and makes it easier to slice.
Tips for Success
-
Slice potatoes evenly: Thin, uniform slices ensure even cooking. A mandoline slicer works great for this.
-
Don’t skip the resting time: It helps the casserole firm up and enhances the texture.
-
Use good-quality cheese: Freshly shredded cheese melts better than pre-packaged varieties.
-
Season each layer: This builds flavor throughout the dish.
Variations and Add-Ins
This casserole is incredibly adaptable. Here are a few ideas to make it your own:
-
Add vegetables: Mushrooms, spinach, or bell peppers work beautifully.
-
Swap the protein: Use ground chicken or turkey instead of beef.
-
Spice it up: Add chili flakes or jalapeños for a kick.
-
Different cheeses: Try mozzarella, Monterey Jack, or a blend for a new flavor profile.
-
Cream of soup shortcut: Replace the homemade sauce with canned cream of mushroom or cheddar soup for a quicker version.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, cover and warm in the oven at 175°C (350°F) until heated through, or microwave individual portions.
This casserole also freezes well. Wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Serving Suggestions
Serve this Cheesy Ground Beef Scalloped Potato Casserole with a simple green salad or steamed vegetables for a complete meal. Garlic bread or dinner rolls also pair wonderfully to soak up the creamy sauce.
