01 - Combine ground turkey, breadcrumbs, egg, Parmesan, garlic, onion, parsley, oregano, salt, pepper, and milk in a large bowl. Mix gently until just combined to avoid toughening the texture.
02 - Form the mixture into 16 evenly sized meatballs, approximately the size of golf balls.
03 - Heat 2 tablespoons olive oil in a large skillet over medium heat. Add the meatballs and brown on all sides for 5 to 7 minutes without fully cooking through. Remove and set aside.
04 - In the same skillet, heat 2 tablespoons olive oil. Add minced garlic and sauté for 1 minute until fragrant.
05 - Add crushed tomatoes, dried basil, oregano, sugar, salt, pepper, and optional red pepper flakes. Stir well and bring to a gentle simmer.
06 - Return meatballs to the skillet, nestling them into the sauce. Cover and simmer on low heat for 20 to 25 minutes, ensuring meatballs are fully cooked and sauce has thickened.
07 - Taste and adjust seasoning as needed. Garnish with fresh basil if desired and serve warm over pasta or preferred accompaniment.
