Step 1: Prepare the Chicken: Pat the chicken drumsticks dry with paper towels. Season generously with salt, pepper, and smoked paprika.
Step 2: Saut Aromatics (Optional): For enhanced flavor, saut the chopped onion and minced garlic in a skillet with a little oil over medium heat until softened, about 5 minutes. This step is optional but recommended for a deeper flavor profile.
Step 3: Combine Ingredients in Slow Cooker: Place the sauted onion and garlic (if using) in the bottom of the slow cooker. Arrange the seasoned chicken drumsticks on top.
Step 4: Prepare the Sauce: In a bowl, whisk together the chicken broth, barbecue sauce, apple cider vinegar, and Worcestershire sauce. Pour the sauce over the chicken drumsticks.
Step 5: Slow Cook: Cover the slow cooker and cook on low for 4-6 hours or on high for 2-3 hours, or until the chicken is very tender and easily pulls away from the bone.
Step 6: Shredding and Serving (Optional): Once cooked, the chicken can be shredded in the slow cooker with two forks and stirred into the sauce for serving. This step is optional, but this is a great way to thicken the sauce.
Step 7: Serve: Serve the chicken drumsticks with the sauce spooned over. Accompany with your favorite sides, such as mashed potatoes, rice, or roasted vegetables.
Optional tips: For a thicker sauce, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir into the slow cooker during the last 30 minutes of cooking. Chicken thighs can be used as a substitution. Any type of barbecue sauce works well.
