Begin by seasoning your chicken drumsticks thoroughly. In a large bowl, sprinkle salt, pepper, garlic powder, and onion powder evenly over the chicken legs. Make sure to rub the spices into the meat for enhanced flavor. Allow the seasoned chicken to sit for about 15 minutes to absorb the spices.

Once your chicken is seasoned, place the drumsticks into the crockpot in a single layer if possible. This ensures even cooking and allows the flavors to infuse beautifully. If desired, you can also layer in some chopped vegetables like carrots or potatoes at this stage. Close the lid to keep all the heat and moisture locked in.

Set your slow cooker to low heat and let the chicken legs cook for 6 to 7 hours, or you can opt for high heat for 3 to 4 hours. The slow cooking will render the meat tender, with an internal temperature reaching 165°F. Check occasionally to resist the urge to lift the lid.

Once your crockpot chicken legs are perfectly cooked, carefully remove them from the slow cooker. Let them rest for about 5 minutes on a plate, which helps retain their juices and moisture. Serve them with your favorite sides, such as creamy mashed potatoes or a fresh salad.
