Cook on low for 7 to 8 hours (or until an instant read thermometer reads 165F in the thickest part.)
To thicken the sauce and make a glaze for the chicken, transfer the sauce to a small pot on the stovetop. Whisk together the cornstarch and water. Bring the sauce to a bubble and stir in the cornstarch mixture. Simmer for a minute or so until thickened.
Serve chicken over mashed potatoes or rice with some of the sauce and enjoy!
Notes
Boneless thighs or breasts can be used instead, but the cooking time should be cut in half or until an internal temperature reaches 165F.
