01 - Wash cucumbers thoroughly and slice them into 1/8-inch rounds using a mandoline for uniform thickness.
02 - Place cucumber slices in a large bowl.
03 - Whisk together olive oil and lemon juice in a small bowl. Drizzle over cucumber slices and toss gently to coat evenly.
04 - Combine all ranch seasoning ingredients in a separate bowl. Sprinkle over coated cucumbers, tossing thoroughly for even coverage.
05 - Spread cucumber slices in a single layer on dehydrator trays or parchment-lined baking sheets.
06 - Set dehydrator to 135°F and dry for 2-4 hours, flipping trays halfway through, until chips achieve desired crispness.
07 - Preheat oven to 200°F. Bake for 2-3 hours, flipping halfway, until chips are completely dry and crispy.
08 - Allow chips to cool completely on the trays before serving to ensure maximum crunch.
