Prep the Zucchini: Using a mandolin slicer or food processor, carefully slice your zucchini very thinly, aiming for about 1/8 inch thick.
Draw Out Moisture: Arrange the thin zucchini slices in layers within a colander or sieve, sprinkling a little salt (about 1/4 teaspoon total) between each layer. Let them sit for a full hour to naturally release excess water.
Get Ready to Bake: While the zucchini drains, preheat your oven to a low 225°F (107°C) and line two large baking sheets with parchment paper.
Dry & Arrange: Pat the zucchini slices thoroughly dry using a clean tea towel. Then, spread them out in a single layer on your prepared baking sheets, ensuring none of the slices are touching.
Lightly Oil & Season: Lightly mist the tops of the zucchini with avocado oil spray, or gently brush with a small amount of liquid oil. In a small spice shaker, combine the smoked paprika, ground black pepper, and the remaining salt. Sprinkle this flavorful mixture evenly over all the zucchini slices.
Bake to Crisp Perfection: Bake for 70 to 90 minutes, or until the chips are completely dry, lightly browned, and wonderfully crisp. For even baking, rotate the sheets halfway through. If some chips crisp up sooner, carefully remove them and let the others continue baking.
Cool & Enjoy: Sprinkle with additional salt to taste if desired. Serve immediately for the best crunch.
