Make It at Home: Meatball Marinara 6-Inch Recipe
A homemade version of the Subway Meatball Marinara 6-Inch with similar nutrition and flavor.
Ingredients
- •450g (1 lb) ground beef (80/20 blend)
- •225g (1/2 lb) ground pork
- •1/3 cup Italian-style breadcrumbs
- •1 large egg
- •2 cloves garlic, minced
- •2 tablespoons finely chopped fresh parsley
- •1/4 cup finely grated Parmesan cheese
- •1/2 teaspoon salt
- •1/4 teaspoon black pepper
- •1/2 teaspoon dried oregano
- •680g (24 oz) marinara sauce (one jar)
- •4 Italian-style sub rolls, about 15cm (6 inches) each
- •4 slices provolone cheese
- •Extra grated Parmesan for serving
Instructions
- 1
Preheat the oven to 200C (400F). Line a baking sheet with parchment paper or lightly grease it with cooking spray.
- 2
In a large bowl, combine the ground beef, ground pork, breadcrumbs, egg, minced garlic, parsley, Parmesan cheese, salt, pepper, and oregano. Mix gently with your hands until just combined. Do not overmix, as this makes the meatballs tough.
- 3
Roll the mixture into meatballs about 3cm (1.25 inches) in diameter. You should get 16 to 20 meatballs. Place them on the prepared baking sheet, spacing them about 2.5cm (1 inch) apart.
- 4
Bake the meatballs for 15 to 18 minutes until browned on the outside and cooked through (internal temperature of 74C / 165F).
- 5
While the meatballs bake, warm the marinara sauce in a large saucepan over medium-low heat. Once the meatballs are done, transfer them into the sauce and simmer for 10 minutes to let them absorb the flavors.
- 6
Slice each sub roll lengthwise, cutting about three-quarters of the way through. Place a slice of provolone cheese inside each roll, then set the rolls on a baking sheet. Broil for 1 to 2 minutes until the cheese melts and the bread is lightly toasted. Watch carefully to avoid burning.
- 7
Spoon 4 to 5 meatballs into each roll along with a generous ladle of marinara sauce. Sprinkle with extra grated Parmesan and serve immediately.

What kind of meat is in Subway meatballs?
Subway meatballs are made from a blend of beef and pork. The recipe also includes breadcrumbs, seasoning, and other binding ingredients. The combination of beef and pork gives the meatballs a richer flavor and more tender texture than beef alone would provide. The meatballs are pre-cooked and then held in marinara sauce at the restaurant.
