01 - In a large mixing bowl, combine the ground chicken, grated onion, minced garlic, chopped parsley, breadcrumbs, milk, egg, salt, black pepper, oregano, and paprika. Gently fold everything together until just evenly incorporated — avoid overmixing to keep the meatballs tender.
02 - Lightly wet your hands to prevent sticking, then portion and roll the mixture into 16 to 18 uniform meatballs.
03 - Pour the olive oil into a large skillet set over medium heat. Allow the oil to shimmer before adding the meatballs.
04 - Arrange the meatballs in batches with slight spacing between each one. Cook 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 350°F oven for 5 minutes after pan-frying.
05 - Serve the meatballs hot alongside your favorite sauce, over pasta, or as a standalone appetizer.
