Preheat your oven to 375°F (190°C) and lightly grease a muffin tin.
In a large bowl, combine ground beef, ground pork, breadcrumbs, Parmesan cheese, onion, milk, egg, garlic, Worcestershire sauce, salt, and pepper. Mix until well combined but do not overwork the meat.
Take a small portion of the meat mixture and flatten it in the palm of your hand. Place a small amount of shredded mozzarella cheese in the center and wrap the meat around the cheese, forming a ball. Place each meatball in a muffin tin compartment.
In a small bowl, mix ketchup and brown sugar until well combined.
Brush the tops of each meatloaf bite with the ketchup and brown sugar mixture.
Bake in the preheated oven for 20-25 minutes, or until the meat is fully cooked and the cheese is melted.
Allow the meatloaf bites to cool slightly before removing from the muffin tin. Serve warm.
Variations & Tips
For a lighter version, try substituting ground turkey or chicken for the beef and pork. You can also experiment with different cheeses, such as cheddar or pepper jack, to change up the flavor profile. For an extra kick, add some finely chopped jalapeños or red pepper flakes to the meat mixture. If you’re looking to incorporate more vegetables, consider adding finely chopped bell peppers or shredded zucchini. For a gluten-free option, use gluten-free breadcrumbs.
