Potato chips are hard to resist, but they aren't exactly doing your body any favors. Baked Zucchini Chips are the answer — thin, crispy slices of zucchini baked low and slow until they turn golden and genuinely crunchy, with a fraction of the carbs and none of the deep frying.
This Baked Zucchini Chips Recipe relies on a simple but essential technique: drawing out the zucchini's natural moisture before baking, then cooking the slices low and slow so they crisp up instead of turning soggy or limp. The result is a homemade chip that actually holds its crunch, seasoned simply with olive oil, salt, and pepper.
This is one of the easiest healthy snack recipes you can make with just one vegetable and a few pantry staples. Whether you're looking for a low carb zucchini chips option to replace store-bought chips or a genuinely crispy baked zucchini chips recipe for an afternoon snack, this one delivers.

Ingredients
- 2 medium zucchini
- 1 teaspoon kosher salt (for drawing out moisture)
- 1 tablespoon olive oil
- ½ teaspoon salt, or to taste
- ¼ teaspoon black pepper
- ½ teaspoon garlic powder (optional)
- ½ teaspoon smoked paprika (optional)
- 2 tablespoons grated parmesan cheese (optional)
Equipment Needed
- Mandoline slicer or sharp knife
- Paper towels
- Baking sheets
- Parchment paper
- Large mixing bowl
- Wire cooling rack (optional, for crisping)
Step-by-Step Instructions
1. Slice the Zucchini
Wash the zucchini and trim off the ends. Using a mandoline slicer or a sharp knife, slice the zucchini into very thin, even rounds, about ⅛ inch thick. A mandoline helps keep the slices consistent, which is important for even baking.
2. Draw Out the Moisture
Lay the zucchini slices in a single layer on paper towels and sprinkle evenly with the kosher salt. Cover with another layer of paper towels and let sit for 15–20 minutes. This step draws out excess water, which is essential for getting a crispy final texture.
3. Pat Dry
After 15–20 minutes, blot the zucchini slices thoroughly with fresh paper towels to remove the surface moisture and much of the salt. There's no need to rinse the slices.
4. Preheat the Oven
Preheat your oven to 225°F. Line two baking sheets with parchment paper.
5. Season the Zucchini
In a large bowl, toss the zucchini slices with olive oil, salt, black pepper, garlic powder, and smoked paprika (if using) until evenly coated.
6. Arrange on the Baking Sheets
Lay the zucchini slices in a single layer on the prepared baking sheets, making sure the slices don't overlap or touch, so air can circulate around each one.
7. Bake Low and Slow
Bake for 1½ to 2 hours, checking periodically after the first hour. The chips won't all crisp up at the same rate, so remove any that are golden and crispy and let the remaining slices continue baking, checking every 10–15 minutes.
8. Cool and Finish
Remove the finished chips from the oven and let them cool completely on the baking sheet — they'll continue to crisp up as they cool. If using parmesan cheese, sprinkle it over the chips while they're still warm so it adheres, then let them cool before serving.
Expert Tips
- Slice the zucchini as thin and evenly as possible. A mandoline slicer makes this much easier than a knife and helps the chips cook and crisp evenly.
- Don't skip the salting step. This draws out the zucchini's natural moisture, which is the key to getting genuinely crispy chips instead of soft, chewy ones.
- Bake low and slow. A lower oven temperature over a longer time allows the moisture to evaporate slowly without burning the chips before they crisp up.
- Check the chips regularly toward the end of baking. Since slices can vary slightly in thickness, some will crisp up faster than others — remove them as they finish rather than waiting for the whole batch.
- Let the chips cool completely before storing. They continue to firm up as they cool, and sealing them while warm can trap moisture and soften them.
- Use parchment paper, not foil. Parchment helps prevent sticking and promotes more even baking than foil.
Common Mistakes to Avoid
- Slicing the zucchini too thick. Thicker slices take much longer to crisp and are more likely to stay soft in the middle.
- Skipping the salting and drying step. Without removing excess moisture first, the chips are far more likely to turn out soggy rather than crispy.
- Overcrowding the baking sheet. Slices that touch or overlap trap steam and won't crisp evenly.
- Baking at too high a temperature. A hot oven can brown the outside of the chips before the inside has had a chance to fully dry out and crisp.
- Storing the chips before they've fully cooled. Warm chips release steam that can soften them once sealed in a container.
Variations
- Parmesan Zucchini Chips: Sprinkle grated parmesan cheese over the chips during the last few minutes of baking for a savory, cheesy crust.
- Spicy Zucchini Chips: Add a pinch of cayenne pepper or red pepper flakes to the seasoning mixture for extra heat.
- Ranch-Style Zucchini Chips: Toss the zucchini slices with a bit of dried dill, onion powder, and garlic powder for a ranch-inspired flavor.
- Breaded Zucchini Chips: Dip the seasoned slices in beaten egg, then coat in seasoned panko breadcrumbs before baking for a crunchier, more indulgent version.
- Air Fryer Version: After salting and drying the slices, air fry at 325°F for 8–12 minutes, flipping halfway through, until crispy.
What to Serve With It
- Tzatziki sauce or Greek yogurt ranch for dipping
- Hummus for a Mediterranean-inspired pairing
- A sandwich or wrap as a lighter side than traditional chips
- A cheese board as a crunchy, low-carb addition
- Marinara sauce for a lighter take on mozzarella sticks
Storage Instructions
Store completely cooled zucchini chips in an airtight container at room temperature for up to 1 week. Adding a paper towel to the container can help absorb any residual moisture and keep the chips crisp longer.
Refrigeration is not recommended, as the added moisture in the fridge tends to soften the chips more quickly.
This recipe is not suitable for freezing, as the texture will not hold up well after thawing.
Reheating Tips
If the chips have softened after a few days, you can re-crisp them in the oven.
- Oven (Best Method): Spread the chips on a baking sheet and warm at 300°F for 5–10 minutes, until crisp again.
- Air Fryer: Reheat at 300°F for 2–3 minutes, checking frequently to avoid burning.
- Avoid the microwave, as it tends to make the chips chewy rather than restoring their crunch.
Frequently Asked Questions
Why aren't my zucchini chips getting crispy? The most common causes are slices that are too thick, skipping the salting and drying step, or baking at too high a temperature. Slice the zucchini as thin as possible, draw out the moisture beforehand, and bake low and slow for the best results.
Do I need a mandoline slicer to make this recipe? A mandoline makes slicing much easier and more consistent, but a sharp knife can also work if you take your time to slice the zucchini as thin and evenly as possible.
How long does it take to bake zucchini chips? Using the low-and-slow method at 225°F, it typically takes about 1½ to 2 hours for the chips to fully crisp up, though exact timing can vary depending on slice thickness and your specific oven.
Can I make this recipe without oil? Yes, though a small amount of olive oil helps the seasonings stick and contributes to a slightly crispier texture. You can reduce the amount or use a light cooking spray instead if you prefer.
Is this recipe keto-friendly? Yes. Zucchini is naturally low in carbohydrates, making these chips a suitable snack for low-carb and ketogenic diets, especially without the optional breaded variation.
Can I use yellow squash instead of zucchini? Yes. Yellow summer squash can be sliced and prepared using the exact same method for a similar crispy chip.
Conclusion

Once you get the hang of slicing and baking them just right, these crispy baked zucchini chips are likely to become a regular replacement for store-bought chips in your kitchen.
