This style of strip jerky is fairly thin and should take between 2-3 hours depending on the thickness. The jerky will be done when it bends and cracks but does not break in half. Some styles of jerky will take longer than others. In my experience, it usually takes between 2-3 hours. Factors may vary from my oven to yours so cooking times are just approximate. All poultry should be cooked until it reaches an internal temperature of at least 165
