# Step-by-Step Guide:
01 - Preheat oven to 225°F. Line two large baking sheets with parchment paper.
02 - Wash and dry zucchinis. Slice them into thin rounds about 1/8 inch thick using a mandoline or sharp knife.
03 - Pat zucchini slices dry thoroughly with paper towels to eliminate excess moisture.
04 - Toss the zucchini rounds in a large bowl with olive oil, sea salt, black pepper, and optional seasonings until evenly coated.
05 - Place slices in a single layer on the prepared baking sheets, ensuring no overlaps.
06 - Bake for 1 hour, then rotate sheets and flip slices. Continue baking an additional 30 to 40 minutes until golden and crisp.
07 - Allow chips to cool completely on the baking sheets to achieve maximum crispness.
08 - Enjoy immediately or store in an airtight container for up to 2 days.
