Cheesy Hamburger Potato Casserole

Step 3: Make the Creamy Sauce

In a medium bowl, combine the sour cream, milk, salt, black pepper, and Dijon mustard. Whisk until smooth. This mixture will make the casserole creamy and help the potatoes cook evenly in the oven.

Step 4: Assemble the Casserole

1. Preheat your oven to 375°F (190°C).
2. Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
3. Spread half of the sliced potatoes evenly at the bottom of the dish.
4. Pour half of the creamy sauce over the potatoes, spreading it evenly.
5. Layer half of the cooked ground beef over the sauce.
6. Repeat the layers with the remaining potatoes, sauce, and beef.

Step 5: Add the Cheese

Sprinkle the shredded cheddar cheese evenly on top of the final layer. Add the Parmesan cheese for extra flavor and a golden crust.

Step 6: Bake

Cover the casserole with aluminum foil and bake in the preheated oven for 40 minutes. Remove the foil and bake for an additional 15–20 minutes, or until the cheese is bubbly and golden brown, and the potatoes are tender when pierced with a fork.

Step 7: Serve

Let the casserole cool for 5–10 minutes before serving. Garnish with chopped parsley if desired. Serve as a standalone dish or with a simple green salad for a complete meal.

Tips for the Perfect Casserole

• Cheese Options: Mix cheddar with Monterey Jack or mozzarella for extra gooeyness.
• Potato Variety: Yukon Gold or red potatoes work best because they hold their shape while baking.
• Make Ahead: Assemble the casserole a day in advance, cover, and refrigerate. Bake just before serving.
• Extra Flavor: Add cooked bacon, sautéed mushrooms, or bell peppers for a richer taste.
