Creating the fantastic Stuffed Italian Meatloaf is simple if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.

2. Prepare Meat Mixture: In a large bowl, combine the ground beef, Italian bread crumbs, egg, Parmesan cheese, Italian seasoning, garlic powder, salt, and pepper. Mix well until all ingredients are evenly incorporated.

3. Form the Meatloaf: Transfer the meat mixture onto the prepared baking sheet. Shape it into a rectangular loaf, about 10 inches long and 5 inches wide.

4. Prepare the Stuffing: In a separate bowl, mix together the mozzarella cheese, sun-dried tomatoes, and fresh basil.

5. Add Stuffing: Create a small indent or well in the center of the meatloaf. Spoon the stuffing mixture into the well, spreading it evenly.

6. Seal the Loaf: Carefully fold the sides of the meatloaf over the stuffing to seal it. Pat down to ensure it holds its shape.

7. Top with Marinara: Spread the marinara sauce evenly over the top of the meatloaf.

8. Bake: Place the meatloaf in the preheated oven and bake for about 1 hour, or until the internal temperature reaches 160°F (70°C).

9. Rest the Meatloaf: Once cooked, remove the meatloaf from the oven and let it rest for 10 minutes before slicing. This allows the juices to redistribute, keeping it moist.

10. Garnish: If desired, garnish with fresh basil leaves before serving.
