---

Instructions

1. Preheat the Oven
   Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
2. Make the Meatball Mixture
   In a large bowl, combine ground beef, breadcrumbs, egg, garlic, parmesan cheese, milk, Italian seasoning, salt, and pepper. Mix until just combined. Do not overmix or the meatballs will be tough.
3. Shape the Meatballs
   Roll the mixture into small meatballs, about 1 to 1½ inches in size, and place them on the prepared baking sheet.
4. Bake the Meatballs
   Bake for 15–18 minutes until cooked through and lightly browned.
5. Heat the Marinara Sauce
   While the meatballs are baking, heat the marinara sauce in a saucepan over medium heat. Once the meatballs are done, add them to the sauce and stir gently to coat.
6. Prepare the Rolls
   Slice the sub rolls lengthwise without cutting all the way through. Place them on a baking dish.
7. Assemble the Subs
   Spoon meatballs and sauce into each roll. Top generously with shredded mozzarella cheese and a sprinkle of parmesan.
8. Add Garlic Butter
   Mix melted butter with garlic powder and brush it lightly over the tops of the rolls.
9. Bake the Assembled Subs
   Bake for 10–12 minutes until the cheese is melted and bubbly and the bread is lightly toasted.
10. Garnish and Serve
    Sprinkle with chopped parsley and serve hot.

Tips for the Best Meatball Subs

Making the perfect meatball sub is easy if you follow a few simple tips:

1. Don’t Overmix the Meat
Overmixing makes meatballs dense instead of tender. Mix just until combined.

2. Use Good Marinara Sauce
A rich, flavorful marinara sauce makes a huge difference. Choose a high-quality store-bought sauce or homemade.

3. Toast the Bread Slightly
Baking the assembled subs prevents soggy bread and gives the sandwich structure.

4. Use Fresh Mozzarella for Extra Melt
Shredded mozzarella melts well, but fresh mozzarella gives an extra creamy texture.

5. Add Cheese Inside and On Top
This creates the ultimate cheesy meatball sub experience.
