There is so much you can do with zucchini, from Zucchini Boats to Zucchini Cakes. But I think these oven-baked zucchini chips might just be my favorite. Who knew you could turn zucchini into crispy chips for snacking?! 

While you won’t mistake these for potato chips, they are an excellent swap for when you’re trying to cut back on carb-heavy snacks and work some extra veggies into your life. They’re paleo-friendly, keto, naturally gluten-free, vegan, and they pretty much fit perfectly into every possible diet since they’re only made with zucchini, oil, and salt.

The next time you find yourself with an abundance of zucchini to use up, you know what to do with it: make zucchini chips!

What You’ll Need

While you only need 3 ingredients for this recipe, you can also add seasonings, flavored salts, etc.

  • Zucchini – Look for one that is large but not too large. The baseball-bat-sized zucchini you harvest at the end of August is not going to work here!
  • Olive oil
  • Kosher salt

How do you make thin sliced zucchini?

I highly recommend using a mandoline slicer; if yours has thickness settings, set it to 2, otherwise, aim for 1/8-inch. It’s very difficult to cut thin, uniform slices of zucchini with a knife.

How to Make Oven-Baked Zucchini Chips

This is one of those recipes that comes down to technique. Follow these instructions closely and you’ll have perfectly crisp zucchini chips!

Prepare. Preheat your oven to 225ºF and line two large baking sheets with silicone baking mats or parchment paper.

Blot the zucchini dry. After you slice your zucchini, place the slices on a sheet of paper towels. Place another paper towel on top and press down to absorb any excess liquid. 

Oil and season the zucchini. Line the zucchini slices on the prepared baking sheet. Don’t overlap them, but they can be very close, as they’ll shrink when they bake. Brush the slices with oil, then sprinkle them with salt.

Bake. Place the baking sheet in the oven and bake the zucchini for 2+ hours, or until they start to brown, feel dry, and seem crisp. 

Cool. Let the zucchini chips cool on the baking sheet, then serve.

Can you make zucchini chips in a dehydrator?

Yes, zucchini chips can be made in a dehydrator, but you’ll need to follow the directions for your food dehydrator to make them. This recipe was developed for making baked zucchini chips in the oven.

Tips for Success

Again: technique is everything here. These tips will help you nail it.

  • Cut thin, uniform slices. Thinly sliced zucchini rounds are a must. Thick slices won’t get crispy, and if your slices are uneven, you’ll have some chips that are burnt while others are still soggy.
  • Be conservative with the salt. Use less salt than you think; the zucchini slices will shrink in the oven, so they can easily get too salty.
  • Don’t walk away. Once you’re nearing the 2-hour mark, you’ll need to keep a close eye on the chips to make sure they don’t burn.
  • Don’t rush them. Bake the zucchini chips until you see that most liquid has cooked off. If you don’t do this, the zucchini will stick to the parchment paper or your chips will be soggy. You’ll also need to let the zucchini chips cool on the pan before removing them.

How to Store

Keep zucchini chips in an airtight container at room temperature for no more than 3 days.

Ingredients 

  • 1 large zucchini
  • 2 tablespoon olive oil
  • Kosher salt

Instructions

  • Preheat oven to 225 °F. 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 aren’t soggy and are crisp.
  • Let cool before removing and serving.
  • Keep in an airtight container for no more than 3 days.

Do you put the oil on both sides?

i just brushed one side but you can do both if you want. it just might be really oily. also, friendly reminder to check comments first - sometimes it takes me awhile answer questions and the comments section can be helpful as others may have already asked. i noticed someone asked this same question right under you :)

Just made these and they turned out great. They also disappeared in less than 5 minutes, so no storage problems :) A couple of things I did differently: After I sliced them on my mandoline and they were dry, I put them in a plastic bag with half the oil. Twisted the bag to capture the air like a balloon and tossed gently until the oil was evenly distributed. Next I laid the slices on a lightly oiled stainless cooling grid that was placed on a cookie sheet. They were bakd at 250 for one hour and came out light brown and crispy critter, in other words, PERFECT! None of the chips stuck. Thanks for the idea!

I'm looking for the actual thickness you sliced them. You mention a setting on your mandoline, but mine has different settings. You mention a video that shows how thick but I'm not finding the video??? Thanks!
