Preheat oven to 225 degrees Fahrenheit. Line two large baking sheets with parchment paper.

Slice your zucchini into super thin slices with a knife or mandolin.

After you slice your zucchini, place the slices on a sheet of paper towels and take another paper towel to draw out excess moisture.

Arrange zucchini on the baking sheet and spray with cooking spray.

Season very lightly since they will shrink and have strong flavors.

Bake for 2+ hours until they start to brown and aren’t soggy and are crisp.
