Instructions:
Step 1
Preheat your oven to 350°F (180°C) and lightly grease a round baking dish or casserole dish with butter or oil.
Step 2
Boil the potato chunks in salted water until fork-tender, then drain them thoroughly and mash until smooth.
Step 3
Heat the oil in a large skillet over medium heat. Add the onion and cook for 2 to 3 minutes until softened, then stir in the garlic and cook for another minute.
Step 4
Add the minced meat to the skillet and cook until fully browned, breaking it into small crumbles as it cooks.
Step 5
Season the meat with salt, black pepper, paprika, and oregano, then continue cooking until any excess liquid has evaporated.
Step 6
In a large bowl, combine the mashed potatoes with the butter and stir until smooth and creamy.
Step 7
Add the eggs and milk to the mashed potatoes, mixing well until fully combined. If using flour, stir it in now for a firmer casserole.
Step 8
Fold the cooked minced meat mixture and half of the mozzarella cheese into the potato mixture until evenly distributed.
Step 9
Transfer the mixture into the prepared baking dish and smooth the top with a spatula.
Step 10
Sprinkle the remaining mozzarella and the Parmesan cheese evenly over the casserole.
Step 11
Bake for 30 to 40 minutes, or until the top is golden brown, bubbling, and lightly crisp around the edges.
Step 12
Allow the casserole to rest for 10 minutes before garnishing with chopped parsley, slicing, and serving warm.
Tips and Variations:
Choose Starchy Potatoes
Russet or Yukon Gold potatoes create a smoother, creamier casserole with the best texture.
Brown the Meat Well
Cooking the minced meat until deeply browned adds richer flavor and prevents the casserole from becoming watery.
Add More Vegetables
Mushrooms, spinach, peas, carrots, corn, or diced bell peppers blend perfectly into the meat mixture.
Try Different Cheeses
Cheddar, Gruyère, Monterey Jack, Gouda, or a blend of cheeses creates an even richer and more flavorful topping.
Make It Creamier
Replace part of the milk with heavy cream or sour cream for an extra creamy and indulgent casserole.
Add a Crispy Finish
Top the cheese with seasoned breadcrumbs before baking for an irresistible golden crunch.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 4 days.
Freeze for Later
Freeze individual portions or the entire baked casserole for up to 3 months, then thaw overnight in the refrigerator before reheating until hot throughout.
