Preheat oven to 170 degrees.

Add green beans and oil to a mixing bowl and toss to coat beans. Evenly spread green beans on a large, parchment lined or non-stick, baking sheet.

Dry beans in the oven for 8 hours or until all beans are crunchy. Turn off the oven and allow to cool completely before storing in an airtight container.

Optional Dehydrator Instructions: Dry at 170 degrees for 8 hours or until crunchy.

*I usually dry my green beans in the oven overnight.
