01 - Preheat the oven to 225°F (110°C) and line two baking sheets with parchment paper.
02 - Pat the zucchini slices dry using paper towels to remove excess moisture.
03 - In a large mixing bowl, toss the 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, making sure slices do not overlap.
05 - Bake for 50 to 60 minutes, rotating the baking sheets halfway through. Monitor closely during the final 10 minutes to prevent burning.
06 - Remove from oven and allow the chips to cool on the baking sheets for 5 to 10 minutes to enhance crispness.
