Preheat oven to 225 degrees. Line two large baking sheets (I used two 17″ baking sheets) with silicon baking mats or parchment paper.

Slice your zucchini on a mandolin. Mine had 1, 2, or 3 for thickness and I used 2.

After you slice your zucchini, place the slices on a sheet of paper towels and take another paper towel and sandwich the zucchini slices and press on them. This helps draw out the liquid so it’ll cook a bit faster.

Line up the zucchini slices on the prepared baking sheet tightly next to each other in a straight line, making sure not to overlap them.

In a small bowl, pour your olive oil in and take a pastry brush to brush the olive oil on each zucchini slice.

Sprinkle salt throughout the baking sheet. Do NOT over-season, in fact, it’s better to use less salt initially because the slices will shrink; so if you over-season, it’ll be way too salty! You can always add more later.

Bake for 2+ hours until they start to brown and are crisp.

Let cool before removing and serving.

Keep in an airtight container for no more than 3 days. (Hahaha, that;s a really good joke! These will disappear so fast, you'll wonder why you didn't make more)
