Ingredients
3–4 medium zucchini (about 900g–1.2kg), washed and thinly sliced
2–3 tbsp olive oil or avocado oil
1 tsp fine sea salt or kosher salt (plus extra to finish)
1/2 tsp garlic powder (optional)
1/2 tsp smoked paprika (optional)
1/4 tsp freshly ground black pepper
2 tbsp grated Parmesan cheese (optional; use vegan parm for dairy-free)
1 tbsp cornstarch or arrowroot powder (helps crisping)
1/2 tsp lemon zest (optional, for finishing)
1 tbsp fresh chopped herbs (parsley, chives, or dill) for garnish (optional)
Dipping sauce of choice (optional) — tzatziki, hummus, or marinara
Instructions
Step 1: Preheat oven and prepare equipment — Preheat your oven to 225°C (435°F) for low-and-slow crisping, or to 200°C (400°F) for faster browning. Line 2-3 baking sheets with parchment paper or use a silicone baking mat. Place a cooling rack on top of one tray if you want extra airflow under the chips.
Step 2: Slice the zucchini — Trim the ends and use a mandoline set to 1/16–1/8 inch (1.5–3 mm) for uniform thin slices. If you don’t have a mandoline, a very sharp chef’s knife will work; slice as evenly as possible.
Step 3: Remove excess moisture — Place the slices in a single layer on paper towels or a clean kitchen towel. Sprinkle lightly with salt and layer with another towel. Press or let sit 5–10 minutes, then blot dry. For best results, gently toss slices in a bowl with 1 tablespoon cornstarch before oiling to draw moisture out.
Step 4: Season and oil — In a large bowl, whisk oil with garlic powder, smoked paprika, black pepper, and a pinch of salt. Add zucchini slices and toss very gently to coat evenly but not soggy. Sprinkle optional grated Parmesan and toss just to adhere.
Step 5: Arrange and bake — Lay each slice flat on the prepared sheets leaving small gaps; do not overlap. For extremely crisp chips, place slices on a wire rack set over the sheet so air circulates under them. Bake for 25–40 minutes depending on oven and slice thickness, turning once at 12–20 minutes for even browning. Watch carefully toward the end to prevent burning.
Step 6: Cool and crisp — Remove from oven when edges are golden and centers look dry. Transfer to a cooling rack (do not leave on hot tray) and let cool 5–10 minutes — they will firm up as they cool. If needed, sprinkle a touch of salt and lemon zest while still warm.
Step 7: Serve or store — Serve warm or at room temperature with your favorite dip. Store completely cooled chips in an airtight container with a paper towel to absorb residual moisture for up to 2 days (best eaten the same day).
Variations
- Parmesan-Herb Zucchini Chips — Toss slices with Parmesan and Italian seasoning before baking. Finish with extra grated Parmesan and chopped parsley for an herbaceous, savory chip.
- Spicy Chili-Lime — Mix oil with chili powder, cayenne, and lime zest. After baking, sprinkle with extra lime zest and a squeeze of lime for a tangy kick.
- Ranch-Style — Add ranch seasoning (dried dill, garlic powder, onion powder, and buttermilk powder) to the oil for chips that taste like classic ranch-flavored snacks. Serve with ranch dip.
- Panko-Crusted Zucchini Chips — For a crunchier texture, dredge slices in beaten egg or a thin yogurt wash, then press gently into panko breadcrumbs and bake until golden. This is less crispy-but-dry and more sturdy for dipping.
- Parmesan + Smoked Paprika — A combination that mimics smoky cheese crackers. The smoked paprika adds depth that pairs well with a peppery parmesan.
- Seasoned Salt & Vinegar — Lightly brush with oil, bake, then toss with malt vinegar spray and seasoned salt while still slightly warm for that tangy chip experience.
Each variation can be tuned by changing spices, using nutritional yeast for a vegan cheesy flavor, or swapping starches (rice flour, chickpea flour) for dietary needs.
Cooking Note
Zucchini contains a lot of water — the single biggest challenge in making crisp baked zucchini chips is moisture. Drawing off as much surface and internal moisture as possible before baking is crucial. Salt helps extract water, but you must blot thoroughly; otherwise, salt will sit on the surface and create a briny, soggy result. For the driest chips, after salting and blotting, lay slices on a cooling rack to air-dry for 10–20 minutes while your oven preheats — any extra drying time helps.
Thickness affects both texture and timing. Slices thinner than 2 mm yield cracker-like chips; thicker slices yield tender centers with crisp edges. Uniformity is essential, so use a mandoline or very steady knife work. Use a light dusting of cornstarch it forms a micro-crust when heated, improving crispness. Don’t over-oil; a light sheen is enough. Consider using a convection oven setting or an oven-safe wire rack to improve airflow. Finally, remove chips from the hot tray immediately to a cooling rack; trapped steam on a hot pan will soften and ruin your crisp work.
Serving Suggestions
Serve baked zucchini chips as an appetizer or snack with a trio of dips to please a crowd: cool tzatziki, smoky roasted red pepper hummus, and a spicy sriracha-yogurt dip are all excellent choices. For a light lunch, pile them alongside a big green salad or use them as a crunchy side to grilled fish or chicken. They also make an adventurous topper for soups — crumble chips over tomato or roasted red pepper soup for a crisp contrast.
For party platters, mix plain and seasoned varieties, arrange in a bowl with fresh herb sprinkles, and add small spoons of dips so guests can sample. For kids’ lunchboxes, pack chips in a separate small container and include a mild ranch or yogurt dip — the chips add texture and a fun twist without deep-fried oil.
Helpful Tips
- Uniform slicing: Use a mandoline for even thickness. Uneven slices bake unevenly; some may burn while others remain soggy.
- Pat dry thoroughly: Use layered paper towels and press gently, or salt and air-dry. Less moisture = more crunch.
- Don’t over-oil: A light mist or thin toss in oil is enough. Excess oil makes chips limp.
- Single layer is essential: Overlapping slices trap steam and prevent crisping. Bake in multiple batches if needed.
- Use wire racks: Elevate slices on a rack to allow airflow underneath. This mimics frying by letting hot air circulate.
- Temperature & time: Start with 200°C (400°F) and monitor. Convection ovens often need less time; check earlier.
- Flip for even color: If baking directly on parchment, flip slices halfway to get color both sides.
- Finish while warm: Add final salt, lemon zest, or cheese while chips are hot so toppings adhere.
- Cool fully before storing: Only store once fully cooled to avoid trapped steam. Use an airtight container with a paper towel.
- Re-crisping: If chips lose crispness, reheat 3–5 minutes in a hot oven (200°C / 400°F) to re-crisp.
Tips for the Best Baked Zucchini Chips
To get the absolute best chips, combine multiple tactics: thin, uniform slices; salt-and-blot drying; a light starch dusting; and elevated baking on wire racks. Choose mature but not overly large zucchini very large fruit can be watery and seedy. Preheat the oven thoroughly and use convection if you have it. Avoid sugar-based glazes or high-moisture marinades that will steam.
If aiming for extra crunch, sprinkle a small amount of panko mixed with Parmesan on some slices for texture contrast. Remember that chips continue to firm as they cool, so remove them from the oven just shy of the browning you expect. Finally, reserve salt or lemon finish for after baking to keep the surface dry during cooking.

FAQs
Q: Can I air-fry zucchini chips instead of baking?
A: Yes. Air fry at 180–190°C (360–375°F) for 8–12 minutes, checking and shaking halfway. Expect very crispy results but work in single layers and avoid overloading the basket.
Q: How thin should I slice the zucchini?
A: Aim for 1–2 mm for cracker-like chips. Thicker slices (3–4 mm) will be crisp at the edges and a touch tender in the center.
Q: Can I make these gluten-free or vegan?
A: Absolutely. Use cornstarch or arrowroot and skip Parmesan. For panko variations, choose gluten-free panko. Use vegan cheese for a cheesy flavor.
Q: How do I store leftovers?
A: Store completely cooled chips in an airtight container at room temperature with a paper towel to absorb moisture. Best consumed within 1–2 days. Re-crisp briefly in the oven if needed.
Q: Why didn’t my chips get crispy?
A: Most likely reasons: slices too thick or uneven, not dried enough before baking, too much oil, or left on the hot pan to cool (trapped steam). Use the drying, light starch, and rack methods to fix this.
Q: Can I season after baking?
A: Yes — finish with flaky sea salt, lemon zest, or a dusting of seasoning blends while chips are still warm so they adhere.
