01 - In a large mixing bowl, combine ground chicken, grated onion, minced garlic, chopped parsley, breadcrumbs, milk, egg, salt, black pepper, oregano, and paprika. Mix gently until just combined—avoid overmixing to keep the meatballs tender.
02 - Lightly wet your hands to prevent sticking and shape the mixture into 16 to 18 equal-sized meatballs, approximately 1.5 inches in diameter.
03 - Heat olive oil in a large skillet over medium heat until the oil shimmers. Arrange the meatballs in batches, spacing them about 1 inch apart to ensure even browning.
04 - Cook the meatballs for 5 to 7 minutes per side until golden brown and fully cooked through, reaching an internal temperature of 165°F. For extra juiciness, transfer to a preheated oven at 350°F for an additional 5 minutes.
05 - Serve hot alongside your favorite sauce, over pasta, or as a standalone appetizer.
