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. Mix gently until just incorporated—do not overwork the mixture or the meatballs will become tough.
02 - Lightly moisten your hands with water to prevent sticking. Portion the mixture and roll into 16 to 18 uniform meatballs, ensuring even sizing for consistent cooking.
03 - Heat the olive oil in a large skillet or frying pan over medium heat until the oil shimmers. Arrange the meatballs in batches, leaving space between each to allow proper browning.
04 - Sear the meatballs for 5 to 7 minutes per side until deeply golden brown and fully cooked through, reaching an internal temperature of 165°F. For added juiciness, transfer to a preheated 350°F oven for 5 minutes to finish.
05 - Serve hot alongside your favorite sauce, over pasta, or as a standalone appetizer with toothpicks for dipping.
