12 (4 ounce) bone-in chicken drumsticks, with skin
Instructions
Mix ketchup, onion, brown sugar, garlic, vegetable oil, Worcestershire sauce, liquid smoke, salt, and pepper together in a bowl.
Place chicken drumsticks in a slow cooker and drizzle sauce over top. Cook on High for 3 hours.
When the 3 hours are almost up, preheat the oven to 400 degrees F (200 degrees C).
Transfer chicken and sauce to a 9x13-inch baking dish.
Cook in the preheated oven until no longer pink at the bone, the juices run clear, and the skin is browned, about 30 minutes. An instant-read thermometer inserted near the bone should read 165 degrees F (74 degrees C).
