01 - Preheat the oven to 225°F. Line two baking sheets with parchment paper.
02 - Pat the zucchini slices dry using paper towels to remove excess moisture.
03 - In a large bowl, toss the zucchini slices with olive oil, sea salt, pepper, and optional seasonings until evenly coated.
04 - Lay zucchini slices in a single layer on the prepared baking sheets, ensuring no overlap.
05 - Bake for 50 to 60 minutes, rotating the baking sheets halfway through. Monitor carefully during the last 10 minutes to prevent burning.
06 - Remove from the oven and cool on the baking sheets for 5 to 10 minutes to allow further crisping before serving.
