Prep: Preheat the oven to 225 degrees Fahrenheit and line two cookie sheets with parchment paper. Set aside.
Slice: Slice your zucchini and thoroughly pat slices dry with a paper towel.
Whisk: In a large bowl, whisk together olive oil, salt, black pepper, and paprika if using.
Toss: Toss zucchini slices in olive oil and stir until all slices are coated with olive oil.
Place on Baking Sheet: Transfer zucchini slices to prepared cookie sheets. Be sure to space evenly over baking sheet so that no slices are overlapping.
Bake: Transfer both baking sheets to the oven and bake for 1 hour and 15 minutes to 2 hours (baking time can vary depending on your oven). Once your slices have been baking for 1 hour and 15 minutes, be sure to check them every 10 minutes, so they do not burn. Zucchini chips will be golden brown and crisp when finished.
