You certainly can make jerky without a dehydrator, although a dehydrator is the easiest to use. Another option is using your oven. Just follow these steps: • Preheat oven to 175 degrees F • Place jerky on a wire rack, with a foil-lined tray underneath. Allow room for air circulation between the jerky pieces. • Bake until dry and leathery, 3 to 4 hours.
