Ingredients You Will Need
For the mashed potatoes:
4 large potatoes (peeled and boiled)
2 tablespoons butter
½ cup warm milk
Salt and pepper to taste
For the meat layer:
400g (14 oz) ground beef
1 small onion (finely chopped)
2 garlic cloves (minced)
½ cup tomato sauce or crushed tomatoes
1 teaspoon paprika (optional)
Salt and pepper to taste
1 tablespoon olive oil
Topping:
1 cup shredded mozzarella or mixed cheese
Step-by-Step Instructions
1. Prepare the Mashed Potatoes
Start by boiling four large peeled potatoes in salted water until they are soft and easily pierced with a fork. Drain them well and transfer to a large mixing bowl. Add the butter and warm milk, then begin mashing using a hand masher or electric mixer until the potatoes are smooth and creamy. Season with salt and pepper to taste. The texture should be soft enough to spread easily, but not runny. Set the mashed potatoes aside while you prepare the meat filling.
2. Cook the Meat Filling
Heat one tablespoon of olive oil in a skillet over medium heat. Once hot, add the finely chopped onion and sauté for about 3 to 4 minutes until it becomes soft and translucent. Add the minced garlic and cook for another minute until fragrant. Add the ground beef to the pan and break it up with a spoon or spatula. Cook until fully browned, which should take around 5 to 7 minutes. Once the beef is cooked, drain any excess fat if necessary. Add the tomato sauce or crushed tomatoes, paprika if using, and season with salt and pepper. Stir well and let the mixture simmer for about 5 to 7 minutes until the sauce thickens slightly and the flavors combine. Remove from heat and let it rest for a few minutes.
3. Assemble the Casserole
Preheat your oven to 180°C (350°F). Take a medium-sized baking dish and lightly grease it with a bit of oil or butter. Start by spreading half of the mashed potatoes evenly across the bottom of the dish, pressing it down gently with a spatula or the back of a spoon. This forms the base layer of your casserole. Spoon the beef mixture over the mashed potatoes, spreading it out into an even layer. Make sure the meat layer reaches all corners of the dish. Top the meat with the remaining mashed potatoes, spreading them out gently and evenly to fully cover the beef. Use a fork or spatula to smooth out the top.
4. Add the Cheese Topping and Bake
Sprinkle the shredded mozzarella or your preferred cheese evenly over the top layer of mashed potatoes. Make sure the cheese is distributed well for a consistent golden finish. Place the baking dish in the preheated oven and bake for 15 to 20 minutes, or until the cheese is melted and golden brown on top. If you want a crispier top, you can switch to broil mode for the last 2 to 3 minutes, but watch it carefully to prevent burning.
Serving Suggestions
Let the casserole rest for 5 to 10 minutes before slicing. This allows the layers to settle and makes it easier to serve clean portions. This dish pairs wonderfully with a simple green salad or lightly steamed vegetables like broccoli or green beans. It’s also delicious on its own, especially with a side of pickles or a spoonful of sour cream.
Storage and Reheating Tips
This casserole stores very well, making it perfect for leftovers or meal prep. Let any remaining portions cool completely before covering and storing in the refrigerator. It will keep fresh for up to 3 days. To reheat, place a portion in the microwave for 1 to 2 minutes, or reheat the entire dish in the oven at 160°C (320°F) for about 15 minutes or until heated through. If freezing, let the casserole cool completely, then wrap tightly with foil or plastic wrap. It can be stored in the freezer for up to one month. Thaw overnight in the fridge and reheat as needed.
