Instructions:
- Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
- In a large bowl, combine the ground beef, bread crumbs, Parmesan cheese, parsley, onion, egg, garlic powder, salt, and pepper. Mix until well combined.
- Take a small amount of the meat mixture and flatten it in your hand. Place a cube of mozzarella cheese in the center and carefully form the meat around the cheese, shaping it into a ball. Repeat with the remaining meat mixture and cheese.
- Place the meatballs on the prepared baking sheet and bake for 20-25 minutes, or until cooked through.
- While the meatballs are baking, heat the marinara sauce in a saucepan over medium heat until warmed through.
- Serve the meatballs with the marinara sauce. Enjoy your delicious Baked Mozzarella Stuffed Meatballs!
