Creating delicious Cheesy Meatball Subs is easier than you might think! Follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).

2. Mix the Meatball Ingredients: In a large bowl, combine the ground beef, breadcrumbs, Parmesan cheese, parsley, egg, minced garlic, salt, black pepper, oregano, and basil. Mix until well blended.

3. Form the Meatballs: Shape the mixture into meatballs, about 1 to 1.5 inches in diameter. You should get around 20 meatballs depending on size.

4. Brown the Meatballs: In a large skillet over medium heat, add a little olive oil. Cook the meatballs in batches until they’re browned on all sides. This should take about 5-7 minutes.

5. Simmer in Sauce: Once browned, add the marinara sauce to the skillet. Cover and let them simmer for about 15–20 minutes, until they’re cooked through.

6. Prepare the Rolls: While the meatballs are cooking, cut the sub rolls in half lengthwise, but don’t cut all the way through. You want them to hold their shape.

7. Assemble the Subs: Remove the meatballs from the sauce and place a few in each sub roll. Spoon some marinara sauce over the meatballs.

8. Add the Cheese: Generously top each sub with shredded mozzarella cheese.

9. Bake: Place the assembled subs on a baking sheet and bake in the preheated oven for about 10–15 minutes, or until the cheese is melted and slightly golden.

10. Serve Immediately: Once done, remove from the oven and let them cool for a couple of minutes. Then, serve hot and enjoy!
