Ingredients You’ll Need
Here’s what you need to make crispy zucchini chips:
Essential Base Ingredients
- 2 medium zucchini (about 400g)
- 1 tsp fine sea salt (for drawing out moisture)
- 1 tbsp olive oil or avocado oil
- ½ tsp garlic powder
- ¼ tsp black pepper
Optional Flavor Boosters
- 2 tbsp grated Parmesan cheese
- 1 tbsp nutritional yeast (vegan alternative)
- ½ tsp dried herbs (oregano, thyme, rosemary)
- ¼ tsp paprika or cayenne for heat
Step-by-Step Instructions
Follow these steps for perfect crispy chips:
Step 1: Prepare the Zucchini
- Wash and dry the zucchini thoroughly.
- Slice into ⅛-inch rounds using a mandoline slicer or sharp knife for even thickness.
- Lay slices on paper towels in a single layer.
- Sprinkle both sides with salt and let sit for 15–20 minutes to draw out moisture.
- Pat completely dry with a clean kitchen towel or paper towels.
Step 2: Season and Coat
- Preheat oven to 225°F (107°C).
- In a mixing bowl, toss the dried zucchini slices with olive oil.
- Add garlic powder, pepper, and any optional seasonings (Parmesan, herbs, paprika).
- Arrange slices on a parchment-lined baking sheet in a single layer.
Step 3: Bake to Perfection
- Bake for 1.5–2 hours, flipping halfway through.
- Check every 30 minutes after the first hour. Remove chips as they become golden brown and crisp.
- Let cool on a wire rack (not the baking sheet!) for maximum crunch.
Optional: For extra crispiness, increase oven to 250°F for the last 10 minutes.
Air Fryer Method
- Preheat air fryer to 250°F.
- Arrange zucchini slices in a single layer in the basket.
- Air fry for 12–15 minutes, flipping halfway.
Expert Tips for Maximum Crispiness
- ✅ Uniform Thickness – Use a mandoline for perfect slices.
- ✅ Don’t Skip Salting – This step removes excess water that makes chips soggy.
- ✅ Low & Slow Wins – High heat browns too fast, leaving chewy centers.
- ✅ Cool on Wire Rack – Prevents steam buildup and sogginess.
Flavor Variations & Substitutions
- Parmesan Herb – Toss with Parmesan and Italian herbs before baking.
- Spicy Kick – Add cayenne, chili powder, and smoked paprika.
- Ranch Style – Mix in onion powder, dill, and chives.
- Asian Twist – Sprinkle with sesame seeds and soy sauce powder.
Dietary Options:

Grandma’s Secret Technique
After salting, cover zucchini slices with a clean towel and press gently to remove even more moisture. Then, transfer chips to a wire rack immediately after baking—this prevents steam from softening them.
FAQ
Why aren’t my zucchini chips crispy?
You didn’t remove enough moisture, or your oven temp was too high. Follow the salting step and bake low and slow.
Can I make zucchini chips without oil?
Yes! Use cooking spray or bake them plain. They’ll still crisp if moisture is removed properly.
How do I keep zucchini chips crispy after baking?
Store in an airtight container with a moisture absorber like a silica packet.
Can I freeze zucchini chips?
No, freezing makes them soggy after thawing. Bake fresh for best results.
