01 - Preheat the oven to 225°F. Line two baking sheets with parchment paper.
02 - Pat the zucchini slices dry thoroughly with paper towels to remove excess moisture.
03 - In a large mixing bowl, toss zucchini slices with olive oil, sea salt, black pepper, and optional seasonings until evenly coated.
04 - Place zucchini slices in a single layer on the prepared baking sheets, avoiding overlap.
05 - Bake for 50 to 60 minutes, rotating the baking sheets midway to ensure even crispness. Monitor closely during the last 10 minutes to prevent burning.
06 - Remove from oven and allow chips to cool on the baking sheets for 5 to 10 minutes to firm up before serving.
