In a large bowl, combine the ground turkey, breadcrumbs, Parmesan, minced garlic, beaten egg, chopped parsley, basil, oregano, salt, and pepper. Mix until just combined.
Using your hands, shape the mixture into meatballs, about 1 to 1.5 inches in diameter. Place them on a baking sheet lined with parchment paper.
Drizzle the olive oil over the meatballs, then bake in the preheated oven for about 20-25 minutes or until golden brown and cooked through.
While the meatballs are baking, cook the spaghetti according to the package instructions until al dente. Drain and set aside.
In a large saucepan, heat the marinara sauce over medium heat. Once the meatballs are finished baking, add them to the sauce, gently simmering for 5-10 minutes to mingle the flavors.
In a large serving bowl, combine the cooked pasta with the meatball and sauce mixture, toss gently to coat.
Serve the pasta hot, garnished with fresh basil leaves and an extra sprinkle of Parmesan cheese if desired.
Notes
Serve with extra Parmesan cheese for added flavor.
