Ingredients

Scale
  • 1 lb ground turkey (93/7 lean-to-fat ratio works best)
  • 1/2 cup plain breadcrumbs (Panko preferred)
  • 1/4 cup milk (whole milk adds richness, any milk works)
  • 1 large egg, lightly beaten
  • 1/4 cup finely grated onion
  • 2 cloves garlic, minced
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon dried oregano
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 tablespoons olive oil (for drizzling)
  • 6 mini slider buns or dinner rolls
  • 1 cup marinara sauce
  • 1 cup shredded mozzarella cheese (low-moisture, part-skim)
  • Optional: fresh basil leaves for garnish

Instructions

  1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
  2. Grate the onion using the small holes of a box grater directly into a large mixing bowl to release the juice.
  3. Add ground turkey, breadcrumbs, milk, beaten egg, minced garlic, Parmesan cheese, oregano, salt, and pepper to the bowl. Mix with your hands until just combined—do not overmix.
  4. Using a 1-tablespoon cookie scoop or your hands, form the mixture into 24 to 30 mini meatballs (about 1 inch in diameter). Place them on the prepared baking sheet, spacing about an inch apart.
  5. Lightly drizzle the meatballs with 2 tablespoons of olive oil.
  6. Bake for 16 to 18 minutes, until golden brown and cooked through (internal temperature should reach 165°F / 74°C).
  7. While the meatballs bake, warm the marinara sauce in a small saucepan over medium-low heat.
  8. Split the mini slider buns in half and toast them on a separate baking sheet in the oven for the last 2 to 3 minutes of baking time, until lightly golden.
  9. Remove meatballs from the oven. Place 4 to 5 mini meatballs on the bottom half of each toasted bun. Spoon about 2 tablespoons of warm marinara sauce over the meatballs. Top with a generous sprinkle of shredded mozzarella cheese.
  10. Return the assembled subs to the oven for 2 to 3 minutes, just until the cheese is melted and bubbly.
  11. Remove from the oven and let cool for 5 minutes before packing into lunchboxes.

Notes

For meal prep, store components separately: meatballs and sauce in one container, buns in another, cheese in a baggie. Assemble fresh each morning to avoid soggy buns. The grated onion is key for moisture—do not skip. For gluten-free, use gluten-free breadcrumbs and buns. For dairy-free, use dairy-free Parmesan and skip mozzarella. Meatballs freeze well for up to 3 months.
