Preheat the oven to 375 degrees and line a baking sheet with parchment paper. Prepare the Stove Top Stuffing mix according to the package directions and set it aside to cool slightly.

In a mixing bowl, combine the ground beef, 1/4 cup of the Parmesan cheese, Italian seasoning, egg, milk, and a pinch of salt and pepper. Mix with your hands until the ingredients are evenly distributed.

Divide the meat mixture into four equal portions. Flatten each portion into a patty, place about 2 tablespoons of prepared stuffing in the center, and fold the meat around the stuffing to form a small loaf. Seal the edges well.

Arrange the mini meatloafs on the baking sheet. Spoon marinara sauce over the top of each one and sprinkle with the remaining Parmesan cheese.

Bake for 25 to 30 minutes until the internal temperature reaches 160 degrees. Let the meatloafs rest for 5 minutes before serving.
