Peel and slice the onions into large thick slices. Place them at the bottom of a crock pot.
Place the chicken in the crock pot (breast side up). Use a basting brush to rub the olive oil all over the skin of the chicken.
Mix all the seasonings together in a small bowl.
Sprinkle the seasoning mixture over the chicken and use the basting brush to coat the chicken with the seasonings.
Cover and cook on low 4-6 hours, or cook on high for 2-3 hours.
Make sure chicken has reached an internal temperature of 165 degrees F. Remove chicken from crock pot carefully.
Let the chicken sit for 5-10 minutes. Then slice and serve. Enjoy!
