Step 1: Prepare the Marinade - In a mixing bowl, whisk together honey, soy sauce, ketchup, olive oil, minced garlic, grated ginger, onion powder, smoked paprika, salt, and black pepper until well combined.
Step 2: Marinate the Chicken - Place the chicken drumsticks in a large resealable bag or shallow dish. Pour the marinade over them, ensuring each piece is coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, or ideally overnight.
Step 3: Load the Slow Cooker - Once marinated, transfer the drumsticks to the slow cooker along with any remaining marinade. Spread them out evenly.
Step 4: Set and Forget - Cover the slow cooker and set it to cook on low for 6-7 hours or on high for 3-4 hours until the chicken reaches an internal temperature of 165°F.
Step 5: Optional Browning - For crispy skin, preheat your oven to broil. Once cooked, transfer the drumsticks to a baking sheet and broil for 3-4 minutes on each side until golden brown.
Step 6: Garnish and Serve - Sprinkle the drumsticks with sesame seeds and sliced green onions before serving warm with your favorite sides.
