In a large mixing bowl, gently combine the ground turkey with breadcrumbs, milk, chopped parsley, minced garlic, and the beaten egg. Use your hands or a spoon to fold everything together just until combined—avoid overmixing to keep the meat tender.
Season the mixture with salt, pepper, and red pepper flakes, then give it a gentle fold. Taste a small amount of the mixture and adjust the seasoning if needed.
Using your hands, shape the mixture into uniform meatballs about 1.5 inches in diameter. Place them on a plate or tray as you go.
Heat a skillet over medium heat and add two tablespoons of olive oil. Once shimmering, carefully add the meatballs, not overcrowding the pan. Brown them on all sides for about 4-5 minutes, until they develop a golden exterior and a slight sizzle.
Transfer the browned meatballs to a baking sheet or dish and place them in a preheated oven at 180°C (350°F). Roast for an additional 10-12 minutes, or until they reach an internal temperature of 74°C (165°F) and are firm to the touch.
Once cooked, remove the meatballs from the oven and let them rest for about 5 minutes. This allows the juices to redistribute, ensuring they stay moist and tender.
Serve the juicy turkey meatballs with your favorite sauce, over pasta, or on their own garnished with extra herbs. Enjoy the tender, flavorful bites with a crispy exterior and moist interior.
