01 - Set the oven to 225°F and line two baking sheets with parchment paper.
02 - Pat zucchini slices dry using paper towels to remove excess moisture.
03 - In a large mixing bowl, combine zucchini slices with olive oil, sea salt, black pepper, and optional garlic powder and smoked paprika until evenly coated.
04 - Place the zucchini slices in a single layer on the prepared baking sheets, avoiding any overlap.
05 - Bake for 50 to 60 minutes, rotating the trays halfway through. Monitor during the last 10 minutes to prevent burning until chips turn golden and crisp.
06 - Remove from oven and allow zucchini chips to cool on the baking sheets for 5 to 10 minutes to enhance crispness.
