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. Whisk together olive oil and lemon juice in a small bowl, then drizzle over the cucumber slices and toss gently to coat evenly.
03 - Combine all ranch seasoning ingredients in a separate bowl. Sprinkle the seasoning blend over the coated cucumber slices, tossing thoroughly to ensure even distribution.
04 - Arrange seasoned cucumber slices in a single layer on dehydrator trays or baking sheets lined with parchment paper, ensuring pieces do not overlap.
05 - Dehydrator method: Set to 135°F and dry for 2-4 hours, flipping halfway through until crisp. Oven method: Preheat to 200°F and bake for 2-3 hours, flipping halfway, until chips are dry and crispy.
06 - Allow chips to cool completely on the trays before serving to achieve maximum crunch texture.
