Baked Potato and Meat Casserole with Creamy Spinach and Mushroom Sauce

Step 2: Prepare the Creamy Spinach and Mushroom Sauce

1. In a saucepan, melt butter over medium heat. Add mushrooms and cook until softened, about 5 minutes.
2. Stir in chopped spinach and cook until wilted.
3. Sprinkle flour over the mixture, stirring constantly for 2 minutes to eliminate the raw taste of flour.
4. Gradually pour in milk, whisking continuously to prevent lumps.
5. Season with nutmeg, salt, and white pepper. Let the sauce thicken for 5-7 minutes, then remove from heat.
6. Stir in Parmesan cheese until melted and smooth.

Step 3: Assemble the Casserole

1. Preheat your oven to 375°F (190°C).
2. Grease a baking dish and layer half of the potato slices on the bottom.
3. Spread the cooked meat mixture evenly over the potatoes.
4. Pour half of the creamy spinach and mushroom sauce over the meat.
5. Add the remaining potato slices on top and pour the remaining sauce to cover completely.

Step 4: Add Toppings and Bake

1. Sprinkle the mozzarella and cheddar cheese evenly over the top of the casserole.
2. Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes.
3. Remove the foil and bake for an additional 15-20 minutes, or until the cheese is bubbly and golden.

Serving Suggestions
Let the casserole rest for 10 minutes before serving. Pair it with a fresh green salad or steamed vegetables for a complete meal.

Tips for Success

1. Slice Potatoes Evenly: Use a mandoline slicer for uniform slices, ensuring even cooking.
2. Meat Options: Swap ground beef with ground turkey, lamb, or diced tofu for a vegetarian version.
3. Cheese Variety: Experiment with Gruyère or Gouda for a unique twist.

This baked potato and meat casserole with creamy spinach and mushroom sauce is bound to become a family favorite, combining layers of flavor and comfort in every bite. Enjoy!
