Instructions

Step 1: Make the Meatball Mixture

In a large bowl, mix together 1 pound ground beef, 1/2 cup breadcrumbs, 1/4 cup whole milk, 1 egg, 1/4 cup grated parmesan cheese, 1 teaspoon garlic powder, 1 teaspoon Italian seasoning, 1 teaspoon salt, and 1/2 teaspoon black pepper. Mix until just combined. Roll into 12 meatballs.

Step 2: Brown the Meatballs

Heat 2 tablespoons olive oil in a large skillet over medium heat. Add the meatballs and cook for 6 to 8 minutes, turning often, until browned on all sides.

Step 3: Cook the Onion and Garlic

Move the meatballs to one side of the skillet. Add the diced onion and cook for 3 minutes until soft. Add 3 cloves minced garlic and cook for 30 seconds.

Step 4: Simmer in Sauce

Pour in 1 jar marinara sauce. Stir gently and simmer for 20 minutes until the sauce thickens and the meatballs are fully cooked.

Step 5: Toast the Rolls

Brush 6 hoagie rolls with 2 tablespoons melted butter. Place them on a baking sheet and toast at 400 degrees for 5 minutes until golden.

Step 6: Build the Subs

Place 2 meatballs into each toasted hoagie roll. Spoon extra marinara sauce on top. Add shredded mozzarella cheese.

Step 7: Melt the Cheese

Bake the subs at 400 degrees for 3 to 5 minutes until the mozzarella cheese melts. Sprinkle with chopped parsley before serving.
