The meatballs are mixed from ground beef, breadcrumbs, egg, Parmesan and parsley, brushed with olive oil and baked at 425°F until they reach 160°F.

They simmer in marinara for 5 minutes, then four go into each toasted roll with sauce and mozzarella for a short return to the oven.

Into the Roll

Assembled once the meatballs are sauced.

  1. The roll

    Split and lightly toasted in the oven.

  2. Meatballs

    Four per roll, straight from the marinara.

  3. Sauce

    Spooned over the meatballs.

  4. Mozzarella

    Scattered on top, then 3 to 5 minutes in the oven.

How to Make It

  1. Meatball mix

    Heat oven to 425°F. Mix ground beef, plain breadcrumbs, large egg, grated Parmesan cheese, chopped parsley, Italian seasoning, kosher salt, and black pepper.

  2. Baked to 160°F

    Shape into 16 meatballs, brush with olive oil, and bake 14 to 16 minutes, until the centers reach 160°F.

  3. Simmered in sauce

    Warm the marinara sauce in a skillet and add the cooked meatballs; simmer 5 minutes.

  4. Rolls toasted

    Split the sub rolls and toast them lightly in the oven.

  5. Filled and melted

    Fill each roll with 4 meatballs and marinara sauce, top with shredded mozzarella cheese, and return to the oven 3 to 5 minutes until the cheese melts.

Why This Recipe Works

  • Baking the meatballs is hands-off and browns them evenly.
  • A short simmer lets the meatballs take on the sauce.
  • Toasting the rolls first keeps them from going soggy.
  • The final bake melts the mozzarella over the top.

Ingredient Notes

Ground beef
One pound, shaped into 16 meatballs.
Marinara sauce
Two cups, warmed in a skillet.
Mozzarella
One and a half cups, shredded.

Success Tips

  • Wet your hands to roll the meatballs smooth and even.
  • Scoop out a little bread from each roll so the meatballs sit in it.
  • Watch the rolls under the cheese; they go from toasted to dark quickly.

Serving Ideas

Serve hot, wrapped in parchment for easier eating.

Storage and Reheating

Refrigerate

Refrigerate meatballs and sauce up to 4 days; assemble subs fresh when possible.
