Low Calorie Zucchini Chips taste salty, crispy, and a little bit cheesy, like potato chips that decided to clean up their act. They work perfectly for snackers who want something crunchy in under 40–45 minutes, without blowing through their calories for the day. I tested these so many times that my husband now side-eyes regular chips at parties.
Why Low Calorie Zucchini Chips Is Worth It
Low Calorie Zucchini Chips give you that crunchy, salty snack feeling with a fraction of the calories of regular chips. You still get the satisfaction of snacking, but you also sneak in a serving of vegetables without feeling like you ate a salad.
You also need only a few basic ingredients and one sheet pan or air fryer basket. Cleanup stays easy, the process feels simple, and the results taste fancy enough to serve to guests.
“These Low Calorie Zucchini Chips taste like snack food but behave like a veggie, which feels like cheating in the best way possible. ★★★★★”
Ingredients You Need
Zucchini
- 2 medium zucchini, firm and bright green
- Choose smaller zucchini for less water and better crunch.
- Avoid huge zucchini; they hold more moisture and turn soggy.
Seasoning & Coating
- 1–2 tablespoons olive oil or avocado oil
- Spray oil works great and keeps calories lower.
- 2–3 tablespoons grated Parmesan cheese
- Use the finely grated kind; it sticks better than big shreds.
- Shelf-stable “green can” Parmesan works in a pinch and sticks very well.
- 1–1½ teaspoons kosher salt
- Use less if your Parmesan tastes very salty.
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon smoked paprika or sweet paprika
- Smoked paprika gives a “BBQ chip” vibe.
- Optional heat: ¼ teaspoon chili powder or cayenne
Optional Crunch Boost
These add a little texture while still staying light.
- 2 tablespoons panko breadcrumbs (regular or whole wheat)
- Use gluten-free panko if you avoid gluten.
- 1 tablespoon nutritional yeast
- Adds cheesy flavor if you skip dairy.
Equipment
- Sharp knife or mandoline slicer
- Mandoline gives super even slices and more consistent crispiness.
- Large mixing bowl
- Paper towels or clean kitchen towels
- Wire rack (cooling rack) that fits on a sheet pan
- Large rimmed baking sheet
- Parchment paper (if you skip the rack)
- Air fryer (optional, for an alternate method)
- Tongs or spatula
Quick Tips & substitutions
- Slice zucchini 1/8 inch thick for best crunch; thicker slices stay soft.
- Pat slices very dry with paper towels to remove moisture before seasoning.
- Salt slices lightly, wait 10 minutes, then blot again to pull out extra water.
- Use spray oil to coat the slices evenly and keep calories low.
- Swap Parmesan with nutritional yeast for dairy-free zucchini chips.
- Choose smoked paprika and chili powder for a BBQ-style flavor.
- Use Italian seasoning and extra Parmesan for a “pizza chip” flavor.
- Bake on a wire rack set over a sheet pan so air can circulate and crisp both sides.
- Rotate the pan halfway through baking to prevent hot spots.
- Pull chips as they finish; some slices cook faster than others.
- Use yellow squash the same way if you have extra.
- Skip breadcrumbs for gluten-free and lower carb zucchini chips.
- Use an air fryer at 250–275°F for faster, extra-crispy chips.
How to Make Low Calorie Zucchini Chips
Step 1: Slice and prep the zucchini
Wash and dry the zucchini. Trim the ends, then slice into 1/8-inch rounds with a sharp knife or mandoline. Lay the slices in a single layer on paper towels.
Sprinkle a small pinch of salt over the slices and let them sit 10–15 minutes. Blot the tops with more paper towels to soak up released moisture. This step sets you up for crisp, not floppy, chips.
Step 2: Season the slices
Add the dried zucchini slices to a large mixing bowl. Drizzle or spray with oil, then toss until every slice looks lightly coated.
In a small bowl, mix Parmesan, pepper, garlic powder, onion powder, paprika, and any optional spices. Sprinkle the mixture over the zucchini and toss again so the seasoning clings to each slice. If you use panko or nutritional yeast, add them now and toss once more.
Step 3: Arrange on the pan
Place a wire rack on top of a rimmed baking sheet. Lightly spray the rack with oil so the chips release easily.
Lay the zucchini slices in a single layer on the rack. Avoid overlapping or stacking, or they will steam instead of crisp. If you skip the rack, line the sheet pan with parchment and flip the slices halfway through baking.
Step 4: Bake until crisp
Preheat your oven to 225–250°F (low and slow works best). Slide the pan into the center of the oven. Bake 45–70 minutes, depending on thickness and oven quirks.
Check after 35–40 minutes and pull any chips that already turned golden and crisp. Rotate the pan and keep baking until most slices feel dry and crunchy at the edges. They crisp even more as they cool.
Step 5: Air fryer method (alternate)
Set your air fryer to 250–275°F. Arrange seasoned zucchini slices in a single layer in the basket or on the tray. Leave a little space between slices.
Air fry 15–25 minutes, checking often after the 12-minute mark. Shake the basket or flip slices once to encourage even crisping. Pull finished chips as they turn golden and firm.
Step 6: Season to finish
Taste one chip once it cools slightly. Add a tiny pinch of extra salt or more smoked paprika if you want stronger flavor.
You can sprinkle a bit more Parmesan or nutritional yeast while the chips still feel warm so it sticks. Let the chips cool fully on the rack so they stay crisp.
Recipe Variations
- Gluten-free: Skip panko or use gluten-free panko; keep the rest of the recipe the same.
- Dairy-free: Replace Parmesan with nutritional yeast and a pinch of extra salt.
- Low carb / keto: Skip breadcrumbs and use only Parmesan and spices.
- Spicy chips: Add cayenne, chipotle powder, or extra chili powder.
- Herb lovers: Toss with Italian seasoning, dried basil, or dried oregano.
- “Salt & vinegar” style: Toss slices with 1–2 tablespoons vinegar, pat dry again, then season and bake.
- Ranch-inspired: Use garlic powder, onion powder, dried dill, and dried parsley.
- Everything bagel chips: Sprinkle everything bagel seasoning instead of paprika.
Ways to Serve Low Calorie Zucchini Chips
- Serve as a crunchy side with grilled chicken, turkey burgers, or veggie burgers.
- Pack in lunchboxes as a lighter chip alternative.
- Pair with Greek yogurt dip, hummus, or salsa.
- Crush and use as a topping for salads or grain bowls.
- Serve alongside sandwiches, wraps, or lettuce wraps.
- Use as a base for “nachos” with black beans, pico de gallo, and a little cheese.
Storage Success
Let Low Calorie Zucchini Chips cool completely before you store them, or trapped steam will soften them. Store them in an airtight container at room temperature for up to 2–3 days. If they lose some crunch, spread them on a baking sheet and warm them in a 250°F oven for 5–8 minutes to crisp back up. Keep them away from humid spots in the kitchen, since moisture turns them chewy fast.

Instructions
- Wash and dry the zucchini. Trim the ends, then slice into 1/8-inch rounds using a sharp knife or mandoline for even thickness.
- Lay the zucchini slices in a single layer on paper towels. Lightly sprinkle with a pinch of salt and let sit 10–15 minutes to draw out moisture, then blot the tops very well with more paper towels.
- Place the dried zucchini slices in a large mixing bowl. Drizzle or spray with the oil and toss until the slices are lightly and evenly coated.
- In a small bowl, combine Parmesan, salt, black pepper, garlic powder, onion powder, paprika, and optional chili powder or cayenne. Sprinkle this mixture over the zucchini and toss until the seasoning clings to each slice. If using panko and/or nutritional yeast, add them and toss again to coat.
- Set a wire rack on top of a rimmed baking sheet and lightly coat the rack with oil spray. Arrange the seasoned zucchini slices in a single layer on the rack without overlapping so they can crisp instead of steam.
- Preheat the oven to 225–250°F. Place the baking sheet in the center of the oven and bake for 45–70 minutes, rotating the pan halfway through. Begin checking around 35–40 minutes and pull any chips that are already golden and crisp. The chips will continue to crisp slightly as they cool.
- For the air fryer method, preheat the air fryer to 250–275°F. Arrange the seasoned zucchini slices in a single layer in the basket or on the tray, leaving space between slices. Air fry 15–25 minutes, shaking the basket or flipping once, and pull chips as they turn golden and firm.
- Let the chips cool slightly, then taste and add a tiny pinch of extra salt or smoked paprika if desired. Sprinkle with a bit more Parmesan or nutritional yeast while still warm if you like. Cool completely on the rack before serving or storing so they stay crisp.
