How thinly you slice your zucchini will affect how long it'll take in the oven. We recommend checking on the chips after about an hour, though it'll almost definitely take longer than that. If you're using an air fryer, they'll cook much faster, but you'll need to work with much smaller batches. Got a mandolin? Now is the time to use it.
