Preheat your oven to 250°F (120°C). This low temperature helps the zucchini slices to slowly dehydrate and crisp up without burning. Ensure even baking for a perfect crunch.

Wash and dry your zucchinis thoroughly. Slice them into thin rounds using a sharp knife or mandolin, aiming for about 1/8-inch thickness. Consistent slices help ensure even baking.

Lay zucchini slices on a paper towel, sprinkle lightly with salt, and let sit for 10 minutes. Salt draws out moisture. Pat slices gently with another paper towel to soak up excess water.

In a large bowl, toss zucchini slices with olive oil until evenly coated. Add salt, garlic powder, smoked paprika, black pepper, and grated parmesan if desired. Toss again to mix seasonings.

Line a baking sheet with parchment paper. Arrange zucchini slices in a single layer, avoiding overlap. Bake at 250°F (120°C) for 1.5 to 2 hours, flipping halfway through, to allow even crisping.

After about 90 minutes, check your chips. They should be golden brown and crispy. If still soft, continue baking. Once done, remove from the oven and cool for 5 minutes to firm up.
