These mini meatloaf muffins are almost too cute to eat! They have all the classic flavors you love in a bite-sized, hand-held portion.
Preheat your oven to 425°F. Grease a muffin pan and set aside.
In a small bowl, whisk together the ketchup, chili sauce, brown sugar, and Dijon mustard until well combined. Set aside.
Heat the oil in a skillet over medium heat. Sauté the diced onion until softened, about 3 to 4 minutes. Remove from heat and let the onions cool.
In a large mixing bowl, combine the ground beef, cooled onions, bell pepper, barbecue sauce, Worcestershire sauce, breadcrumbs, egg, parsley, salt, and pepper. Mix until just combined, being careful not to overwork the meat.
Divide the meat mixture into 10 portions. Take each portion, flatten it slightly, and place a cube of mozzarella in the center. Fold the meat around the cheese and shape into a ball, then place it in a muffin well. Repeat for the remaining portions.
Spoon the prepared glaze evenly over the tops of each meatloaf muffin.
Bake uncovered for 20-25 minutes, or until the internal temperature reaches 160°F. Allow the meatloaf muffins to rest for 5 minutes before serving.
Garnish with additional fresh parsley, if desired, and serve hot. Enjoy!
