Baked Potato and Meat Casserole with Creamy Spinach and Mushroom Sauce

Preheat your oven to 180°C (356°F).
Grease a large baking dish with a little butter or oil.
Begin layering the casserole by placing a layer of sliced potatoes on the bottom of the dish. Lightly season the potato layer with salt and pepper.
Spread half of the meat mixture over the potatoes, pressing it down gently to form an even layer.
Add another layer of potatoes on top of the meat, followed by the remaining meat mixture.
Finish with a final layer of potatoes on top.
Pour the creamy spinach and mushroom sauce over the top layer, ensuring that the sauce covers the potatoes completely.
5. Bake the Casserole:
Cover the baking dish with foil and place it in the preheated oven.
Bake the casserole for 30-35 minutes, or until the potatoes are tender and the meat is cooked through.
Remove the foil and bake for an additional 10-15 minutes, or until the top is golden brown and bubbling.
Once baked, let the casserole rest for 5-10 minutes before serving.
Cooking Tips:

Potato Preparation: To ensure even cooking, slice the potatoes as evenly as possible. A mandoline slicer is a great tool for getting consistent slices.
Creamy Sauce Consistency: If the sauce is too thick, you can add a splash of milk or broth to loosen it up before pouring it over the casserole.
Cheese Choices: Feel free to experiment with different types of cheese. Cheddar, Gruyère, or even gouda would work well in this dish, adding a unique flavor.
Meat Options: You can use beef for more flavor, or swap in chicken or turkey for a lighter option.
Adding Vegetables: You can add extra vegetables to the meat mixture, such as grated carrots or bell peppers, to increase the nutritional value of the dish.
Storage:
Refrigeration: Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
Freezing: This casserole can also be frozen. Once cooled, wrap it tightly in plastic wrap and foil. Freeze for up to 1 month. To serve, thaw overnight in the fridge and reheat in the oven until heated through.
