In large glass or plastic bowl, add all ingredients and stir until well blended.
Place beef slices in seasoning mixture and stir until all pieces are coated.
Cover bowl with plastic wrap and place in refrigerator.
Let beef slices marinate for 24-48 hours.
Shake off excess marinade and lay slices on dehydrator trays making sure slices don't touch.
Process at 160° F for 10 hours or until desired doneness. Check for desired consistency about half way through the cycle. Thinner slices may need less processing time.
No need to turn meat when using a dehydrator.
Let jerky cool completely before storing.
