Preheat the oven to 235 degrees fahrenheit or 112 degrees celsius
Next, slice the zucchini into one eighth inch thick discs, it is important that they are as close to the same size as possible so they cook evenly and turn out crispy
Lay the zucchini out between two layers of paper towel and press down, I like to use a rolling pin, this helps to removes excess water
Then spread the zucchini out on a baking sheet with parchment paper with a pinch of sea salt, no oil needed
Bake in the oven for around 1-2 hours. The time depends on how thick your zucchini chips are, just check on them ever 30 or so minutes.
