Ingredients

Scale

Meatballs

  • 1 pound lean ground beef
  • ¼ cup Italian bread crumbs
  • ¼ cup grated parmesan cheese (pre-grated from the jar)
  • ¼ cup yellow onion (minced, about ¼ small onion)
  • 2 teaspoons garlic (minced, about 2 cloves)
  • 1 egg
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1 teaspoon salt
  • ½ teaspoon pepper
  • 8 ounces mozzarella cheese (diced into ½ inch pieces)

Additional

  • Marinara sauce (quantity as desired, approximately 2 cups recommended)
  • Spaghetti noodles (enough to serve 4 people, about 12 ounces dry)

Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees Fahrenheit and line a baking sheet with parchment paper to prevent sticking and facilitate easy cleanup.
  2. Mix Ingredients: In a large bowl, combine the ground beef, Italian bread crumbs, grated parmesan cheese, minced yellow onion, minced garlic, egg, dried oregano, dried basil, salt, and pepper. Use your hands or a spoon to mix everything until just combined, taking care not to overmix which can make the meatballs tough.
  3. Form Meatballs: Take about 1½ tablespoons of the meatball mixture and flatten it slightly in your hand. Place one piece of diced mozzarella cheese in the center and then mold the meat around the cheese to form a smooth 1-inch diameter ball, ensuring the cheese is completely enclosed to prevent leakage during baking.
  4. Bake Meatballs: Arrange the formed meatballs evenly spaced on the prepared baking sheet. Bake in the preheated oven for 15-20 minutes, flipping the meatballs halfway through cooking to ensure even browning and thorough cooking inside.
  5. Cook Spaghetti: While the meatballs bake, prepare the spaghetti noodles according to the package directions until al dente. Drain and set aside.
  6. Combine with Sauce: Once the meatballs are baked, transfer them to a large saucepan or pot. Pour marinara sauce over the meatballs and cook over medium-high heat until the sauce is warmed through and the meatballs are well coated, stirring gently to avoid breaking them.
  7. Serve: Serve the mozzarella stuffed meatballs and sauce hot over the prepared spaghetti noodles for a delicious, comforting meal.

Notes

  • For a spicier version, consider adding red pepper flakes to the meat mixture or marinara sauce.
  • Use fresh mozzarella for a creamier cheese center, but dry it well before dicing to minimize moisture.
  • Make sure to seal the meat tightly around the cheese to avoid cheese leaking during baking.
  • Leftover meatballs can be refrigerated for up to 3 days or frozen for up to 3 months.
  • Use gluten-free bread crumbs to make this recipe gluten-free friendly.
