1 (6 pound) bone-in turkey breast
1 (1 ounce) envelope dry onion soup mix
Rinse the turkey breast and pat dry. Cut off any excess skin, but leave the skin covering the breast. Rub the onion soup mix all over outside of the turkey and under the skin. Place in a slow cooker. Cover, and cook on High for 1 hour, then set to Low, and cook for 7 hours.
