01 - In a large bowl, combine ground chicken, grated onion, minced garlic, parsley, breadcrumbs, milk, egg, salt, pepper, oregano, and paprika. Mix until just combined — do not overmix 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. Add meatballs in batches, spacing them slightly apart to ensure even browning.
04 - Cook for 5 to 7 minutes per side until golden brown and cooked through to an internal temperature of 165°F. For extra juiciness, optionally finish in a preheated oven at 350°F for 5 minutes.
05 - Serve hot with your favorite sauce, alongside pasta, or as appetizers. Pairs well with tomato sauce, tzatziki, or sweet chili dip.
