Making restaurant-quality Air Fryer Veggie Chips at home is surprisingly simple when you know the secret to extracting moisture. There is nothing quite like the deeply satisfying crunch of perfectly dehydrated, brightly colored root vegetables and squash. By utilizing your air fryer’s convection power, you can achieve that irresistible, light crispness without deep-frying.
This method yields gorgeously crinkled, slightly curled sweet potato slices with a deep orange hue, accompanied by crispy dark purple beet chips and lightly browned green zucchini slices. Each delicate vegetable round boasts a slight, flavorful char on the edges. Finished with a minimal misting of olive oil and speckled with coarse white sea salt flakes, these chips look stunning piled high in a rustic ceramic bowl.

Why You Will Love These Rainbow Air Fryer Veggie Chips
Unmatched Visual Appeal: The vibrant deep orange, dark purple, and earthy green tones create a stunning mosaic that makes healthy snacking feel gourmet.
Incredible Textural Contrast: Experience the satisfying snap of crispy beets, the delicate crunch of lightly browned zucchini, and the slightly curled, crinkled edges of perfectly roasted sweet potatoes.
Light & Greaseless: A mere whisper of olive oil provides a glistening finish and binds the coarse sea salt without leaving a heavy, oily residue on your fingers.
Customizable Char: You control the cooking time to achieve just the right amount of rustic, caramelized char along the very edges of each chip.
Essential Components for the Perfect Crunch
Sweet Potatoes: You will need 1 medium (about 8 oz / 225g) sweet potato to provide those beautiful, deep orange chips. Their natural sugars caramelize perfectly in the high heat of the air fryer.
Beets: Grab 1 medium (about 6 oz / 170g) red beet for a striking, dark purple contrast. Beets offer an earthy, robust flavor that deepens intensely as they crisp up.
Zucchini: Use 1 medium (about 7 oz / 200g) green zucchini, sliced thin. Because zucchini holds so much water, it requires careful moisture extraction to achieve a lightly browned, crispy green chip.
Olive Oil Spray: Keep 1 tbsp (15ml) of high-quality extra virgin olive oil in a fine mist sprayer. This light misting creates the glossy finish necessary to conduct heat evenly without making the chips soggy.
Coarse White Sea Salt Flakes: Measure out 1 tsp (5g) of flaky sea salt (such as Maldon). These large, bright white crystals stick beautifully to the misted oil, providing dramatic visual contrast and a bursting, clean, salty crunch.
Kosher Salt (For Sweating): Keep 1 tsp (5g) of standard kosher salt on hand to draw the excess water out of your moisture-heavy vegetables before they ever touch the air fryer basket.

Crucial Tools for Wafer-Thin Vegetable Slices
To master these Air Fryer Veggie Chips, uniformity is your absolute best friend. A high-quality kitchen mandoline is strictly required to slice the vegetables to a precise 1/16-inch (1.5mm) thickness. If you want the sweet potatoes to have a beautiful, ruffled texture, attach a crinkle-cut blade specifically for the orange tubers.
You will also need a large roll of highly absorbent paper towels or a set of clean, lint-free kitchen tea towels. Extracting surface moisture is non-negotiable for achieving a loud, snappy crunch. Finally, ensure your air fryer basket is immaculately clean so the delicate slices do not stick to old residue.
Step-by-Step Guide to Crispy Air-Fried Root & Squash Chips
Prepping and Purging Moisture (The Secret Step)
Wash and dry all your vegetables thoroughly. Using your mandoline, slice the sweet potato (using a crinkle blade if desired), the beet, and the zucchini into uniform 1/16-inch (1.5mm) rounds. Keep the vegetable types in separate piles, as they will require different cooking times.
Lay the zucchini and beet slices flat on a layer of paper towels. Sprinkle them lightly with the standard kosher salt to initiate the “sweating” process. Let them sit for 15 minutes to draw out the excess water, then firmly pat them completely dry with another paper towel.
While the other vegetables sweat, submerge your sweet potato slices in a bowl of ice-cold water for 15 minutes. This draws out the excess surface starches that can cause burning. Drain them, rinse thoroughly, and pat them aggressively dry until absolutely no moisture remains on the surface.
The Air Frying Process for Maximum Crispiness
Preheat your air fryer to 300°F (150°C). Working in batches by vegetable type, arrange the dried slices in a single, uncrowded layer in the basket. Lightly mist the tops with the olive oil spray.
Air fry the sweet potatoes for 12-15 minutes, flipping halfway through, until they are slightly curled, crinkled, and deep orange with a faint char on the edges. Remove them to a wire cooling rack; they will crisp further as they cool.
Next, air fry the beets for 12-14 minutes, watching carefully so their dark purple hue doesn’t turn black. Finally, air fry the zucchini slices for 8-10 minutes, looking for a lightly browned green finish with crisp edges.
Once all the vegetables are cooked and cooling on the wire rack, give them one final, incredibly light mist of olive oil. Immediately sprinkle generously with the coarse white sea salt flakes so they adhere securely to the glistening surface. Pile haphazardly in a rustic ceramic bowl to serve.
Pro Tips for Achieving that Perfect Edge Char
Never Overcrowd: Overlapping slices will cause the vegetables to steam rather than fry. Always work in single-layer batches for that perfect crunch.
Watch the Zucchini: Because of its delicate cellular structure, zucchini transitions from beautifully browned to severely burnt in less than 60 seconds. Keep a vigilant eye on the final batch.
The Wire Rack Cool-Down: Do not skip moving the hot chips directly to a wire cooling rack. Air circulation underneath the chips prevents condensation from turning your crispy masterpieces soggy.
Mind the Mandoline: If your slices are thicker than 1/16-inch (1.5mm), the outside will burn before the inside fully dehydrates. Precision slicing is the key to perfect Air Fryer Veggie Chips.
Keeping Your Chips Crispy: Storage Secrets
If you somehow have leftovers, complete cooling is mandatory before storage. Even the slightest hint of residual warmth will create steam inside a container, instantly ruining your crispy texture. Let them sit at room temperature on the wire rack for at least 45 minutes.
Store the completely cooled chips in an airtight glass jar or container at room temperature for up to 3 days. Do not refrigerate them, as the humidity of the fridge will make them limp. If they lose a bit of their crunch, pop them back into a 350°F (175°C) air fryer for 1-2 minutes to revive them.
Pairing Suggestions for Your Crispy Snack
These salty, crunchy chips are incredibly versatile. Serve them alongside a hearty sandwich like a cheesy chicken avocado melt for a dynamic lunch pairing. The crisp, earthy flavors of the beet and sweet potato effortlessly cut through rich, savory lunch meats.
They also make a phenomenal side dish for robust dinners. Try serving a handful next to some spicy loaded taco potato bowls for an extra layer of dipping crunch. If you’re hosting a casual brunch or lunch, pair these colorful chips with a warm, comforting cottage cheese veggie bake for a balanced, vibrant spread.
Frequently Asked Questions About Air Frying Vegetables
Sogginess usually occurs for three reasons: overcrowding the air fryer basket, failing to sweat out the excess moisture with salt before cooking, or slicing the vegetables too thickly. Always use a mandoline for 1/16-inch slices and cook in a single layer.
While you can attempt to use a very sharp chef’s knife, a mandoline is highly recommended. It guarantees uniform thickness, ensuring that all chips dehydrate and crisp up at the exact same rate without half the batch burning.
Yes! Allow them to cool completely on a wire rack—any residual heat will cause condensation and ruin the crispness. Once fully cooled, store them in an airtight glass jar at room temperature for up to 3 days.
Soaking sweet potatoes in ice-cold water draws out excess surface starches. If left on the potato, these starches can cause the edges of the chips to burn rapidly in the air fryer before the center has time to become crispy.
Zucchini cooks much faster than root vegetables like beets and sweet potatoes due to its delicate cellular structure. Always air fry your vegetables in separate batches according to their specific cooking times to prevent burning.
