Instructions:
1. Prepare the mashed potatoes:
- Boil the chopped potatoes in salted water until tender, about 15 minutes.
- Drain and mash the potatoes, then stir in the butter and milk.
- Season with salt and pepper. Optionally, add 1 beaten egg for extra creaminess. Set aside.
2. Make the meat filling:
- In a large skillet, heat the olive oil over medium heat. Add the chopped onion and garlic, and sauté until soft and translucent, about 5 minutes.
- Add the carrot and celery, cooking for another 5-7 minutes until softened.
- Stir in the ground meat, breaking it apart as it cooks. Cook until browned, about 8-10 minutes.
- Add the tomato sauce, oregano, basil, salt, and pepper. Let the mixture simmer for 10-15 minutes until the sauce thickens slightly.
- Stir in the grated Parmesan and set the filling aside.
3. Assemble the pie:
- Preheat the oven to 180°C (350°F).
- In a greased baking dish, spread half of the mashed potatoes on the bottom.
- Spoon the meat mixture evenly on top of the potatoes.
- Cover with the remaining mashed potatoes, spreading them out to create an even layer.
- Sprinkle the shredded mozzarella (or provolone) cheese on top. Optionally, add a handful of breadcrumbs for extra crunch.
4. Bake the pie:
- Bake in the preheated oven for about 25-30 minutes or until the top is golden brown and the cheese is bubbling.
5. Serve:
- Let the Torta di Carne Macinata e Patate cool for a few minutes before serving. It pairs beautifully with a simple green salad or roasted vegetables!
