Rinse and dry chicken legs after removing skin...pat dry with paper towels, don't skip this step! Place legs on a plate or tray.
In a small bowl, combine the garlic, onion powder, paprika, celery salt or seed and Italian seasoning.
Lightly drizzle olive oil over the chicken legs...just a small amount.
Sprinkle the spice mixture evenly over each leg as you place it into the Crockpot. Sprinkle and rub on all sides of the chicken leg.
After all legs are in the Crockpot, I like to add a dash or two of freshly ground black pepper.
Place lid on Crockpot and cook on HIGH for 1 hour. After 1 hour, switch to LOW and let chicken continue to cook for 3-4 hours or until done.
Feel free to adjust spice amounts and types...especially if you are trying to lower your salt intake!
