How to Make Keto Zucchini Chips in the Air Fryer

  1. Set out a mandolin slicer, a medium bowl, and an air fryer. Adjust the mandolin slicer to slice at 1.5 mm. (On my mandolin this is the third smallest notch.)
  2. Carefully slice the zucchini into thin rounds, paying extra attention as you near the end.

Pro Tip: If your mandolin has a handguard, use it!

Frequently Asked Questions

What spices go well on keto zucchini chips?

We use a simple and delightful combo of salt, pepper, and garlic powder to season the chips. But this recipe is great to tweak with your favorite spices! Try making with cumin and chili powder, Italian seasoning, Cajun french fry seasoning, or just about any other flavors you like.

How long do you air fry zucchini chips?

Total the chips need about 10 minutes total in the air fryer.
Air fry the zucchini slices for 5 minutes at 350°F. Then flip, sprinkle with parmesan, and cook for another 5-6 minutes.

Should zucchini chips be refrigerated?

This recipe offers a wonderful low carb option for chip lovers, but zucchini is so moist, it is not possible to air fry them in a way that makes them storable, like store-bought chips. These little guys need to be made and enjoyed on the same day.

Why are my zucchini chips soggy?

If the chips lack that lovely crunch, it’s possible you did not add quite enough salt or let the zucchini slices sweat out in a bowl for long enough. And be sure to pat the excess moisture from the raw pieces before lightly coating them in oil and spices.

Ingredients

US Customary – Metric

Instructions

  • Set out a mandolin slicer, a medium bowl, and an air fryer. Adjust the mandolin slicer to slice at 1.5 mm. (On my mandolin this is the third smallest notch.)
  • Slice the zucchini into thin rounds, being extra careful when you get close to the end. *If you’re mandolin has a handguard, use it!
  • Place the zucchini chips in the bowl and sprinkle with 1/8 teaspoon of salt. Toss well and allow the zucchini chips to sweat out their moisture for at least 10 minutes.
  • Place a long piece of paper towel on the countertop. Preheat the air fryer to 350°F.
  • Once the zucchini chips have had time to sweat, pour off the excess moisture and lay the zucchini chips in a flat layer on the paper towels. Press them gently to remove as much moisture as possible.
  • Move the zucchini chips back to the bowl. Drizzle with olive oil, then sprinkle with garlic powder, and black pepper. Toss well to coat the zucchini chips in the seasoning.
  • Carefully lay a single layer of zucchini chips in the hot air fryer basket. Air fry the zucchini chips for 5 minutes. Use tongs to flip the zucchini chips over.
  • Sprinkle the tops of the zucchini chips with Parmesan cheese. (This is important because it helps weigh down the zucchini chips so they don’t blow around as they dry out in the air fryer.)
  • Then air fry for another 5 to 6 minutes depending on your machine. Repeat in small batches with the remaining zucchini chips.

Notes

We tested this recipe so many ways in multiple air fryers. Some air fryers have extra-strong blowers and will push the thin chips into one corner causing them to not cook evenly. Flipping the chips and coating them and Parmesan makes a big difference!
This recipe offers a wonderful low-carb option for chip lovers, but zucchini is so moist, that it is not possible to air fry them in a way that makes them storable at room temperature, like store-bought chips. These little guys need to be made and enjoyed on the same day.
