Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease a loaf pan.

2. Mix the Meatloaf:

In a large mixing bowl, combine the ground beef, breadcrumbs, ½ cup of shredded mozzarella, Parmesan cheese, eggs, chopped onion, minced garlic, ½ cup of marinara sauce, Italian seasoning, salt, and pepper.
Use your hands to mix the ingredients until well combined, being careful not to overmix.

3. Shape the Meatloaf:

Transfer the meat mixture to the prepared baking sheet or loaf pan, shaping it into a loaf. Press the mixture firmly to ensure it holds together during baking.

4. Bake the Meatloaf:

Spread the remaining ½ cup of marinara sauce evenly over the top of the meatloaf.
Bake in the preheated oven for 45 minutes.

5. Add the Cheese:

After 45 minutes, remove the meatloaf from the oven and sprinkle the remaining ½ cup of shredded mozzarella over the top.
Return the meatloaf to the oven and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly, and the meatloaf is cooked through (internal temperature of 160°F or 70°C).

6. Serve:

Let the meatloaf rest for 5-10 minutes before slicing.
Garnish with fresh parsley and serve hot, with extra marinara sauce on the side if desired.

Tips:

Mix of Meats: You can use a mix of ground beef, pork, and veal for extra flavor and tenderness.
Stuffing Variation: For a twist, you can stuff the meatloaf with a layer of cheese in the middle before baking.

Enjoy your flavorful and cheesy Italian meatloaf!
