Carefully trim any excess skin or fat from the chicken legs, if desired. Pat them dry with paper towels. This helps the sauce adhere better.
Arrange the sliced yellow onion at the bottom of your 6-quart slow cooker. This creates a bed for the chicken and adds flavor.
Place the trimmed chicken legs in a single layer over the onions in the slow cooker. Try not to overcrowd the pot.
Pour the BBQ sauce evenly over the chicken legs. Using a spoon or brush, ensure each leg is well coated with sauce.
Sprinkle the garlic powder and salt evenly over all the chicken legs.
Cover the slow cooker and cook on high for 3-4 hours, or on low for 6-7 hours, until the chicken is tender, juicy, and falls off the bone. Internal temperature should reach 165°F (74°C).
Carefully remove the chicken legs from the slow cooker and serve hot with your favorite side dishes. Enjoy your fall-off-the-bone deliciousness!
Notes
For an extra kick, add a pinch of cayenne pepper or a dash of hot sauce to the BBQ sauce before pouring over the chicken. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. This recipe pairs wonderfully with mashed potatoes, rice, or a simple green salad.
