Zucca Chips North Italia Recipe

North Italia's Zucca Chips are the appetizer that regulars order every single visit without fail — razor-thin rounds of fresh zucchini dipped in a gossamer-light tempura-style batter of flour, cornstarch, sparkling water, and a splash of vinegar, then flash-fried at the right temperature until they emerge shattering-crispy on the outside with a barely-there, tender zucchini interior. The word "zucca" is Italian for squash, and the dish is a celebration of how little a great vegetable needs — just the right cut, the right batter, the right heat, and a generous pinch of flaky salt the moment they come out of the oil. They disappear from the table faster than any other dish North Italia serves, and this copycat version, made correctly with cold sparkling water and properly heated oil, produces the same addictive, paper-thin crunch at home.

Ingredients

For the Zucchini

2 large zucchini (courgettes), washed and dried Choose firm zucchini with no soft spots — the firmer the zucchini, the less water it releases during frying and the crisper the result; medium-large (about 8 inches) is ideal; avoid very large zucchini, which tend to be seedy and watery in the center
- neutral frying oil (vegetable, canola, or peanut) Enough to fill your pot to 1 inch depth; vegetable and canola are the most accessible and have appropriately high smoke points; peanut oil produces a slightly richer result; avoid olive oil, which smokes at frying temperatures and has too strong a flavor
flaky sea salt For finishing immediately after frying — this is not optional; the salt applied to hot chips adheres perfectly and makes the flavor pop in a way that salt added at the table never does

For the Tempura-Style Batter

½ cup all-purpose flour The structural base of the batter — do not substitute self-raising flour or cake flour; all-purpose has the right protein level for a light but cohesive coating
¼ cup cornstarch The key ingredient for exceptional crispiness — cornstarch has less gluten than flour, meaning less chewy coating; it also forms a more glass-like crust when fried; do not reduce this amount
1 tsp baking powder Creates tiny bubbles in the batter as it fries, lightening the coating and adding to the airy, tempura-like texture
1 tsp fine sea salt Seasons the batter itself so the chips taste seasoned from the coating outward
½ tsp black pepper, freshly ground A gentle, barely-perceptible heat in the batter
½ tsp granulated sugar A small pinch that aids browning and adds a subliminal sweetness that balances the salt
¾ cup cold sparkling water (club soda or seltzer) Must be cold — ideally straight from the refrigerator or chilled with ice until just before use; the carbonation creates air bubbles in the batter that expand in the hot oil, producing the light, shattering crust; flat water cannot replicate this effect
1 tsp white wine vinegar or red wine vinegar Adds a microscopic amount of acidity that tightens the gluten in the batter slightly, producing a crisper, less bready coating; also contributes a barely detectable brightness to the flavor

Equipment

1 Mandoline slicer The single most important tool for this recipe — consistent ⅛-inch slices are what separate chips that fry evenly and shatter crisply from thick, uneven pieces that are greasy and soft in the center; a sharp chef's knife works but requires a steady, practiced hand
1 Heavy-bottomed pot, Dutch oven, or deep skillet A heavy bottom retains and regulates heat consistently — oil temperature fluctuations are the main cause of soggy chips; cast iron or enameled cast iron is ideal
1 Instant-read or candy thermometer For monitoring oil temperature precisely at 350–375°F; without this, even experienced fryers can drift into temperatures that produce grease-logged chips (too low) or burnt chips (too high)
2 Medium mixing bowls One for the dry batter components, one for mixing the completed batter
1 Whisk For combining dry ingredients and then incorporating the sparkling water without deflating the bubbles
1 Wire cooling rack set over a baking sheet Crucial for draining — paper towels alone trap steam against the bottom of the chip and cause the underside to go soggy; the rack allows air to circulate on all sides
Tongs or a spider skimmer Cast-iron or stainless-steel pan For lowering chips into the oil and retrieving them safely without splattering
Paper towels Several For an initial quick blot of excess surface moisture before moving to the rack

Method

PREPARE THE ZUCCHINI

Step 1 — Slice the zucchini razor-thin and dry thoroughly. Wash the zucchini under cold water and dry each one completely with a clean kitchen towel — any surface moisture will cause violent splattering when the slice enters the hot oil. Using a mandoline set to its thinnest setting (approximately ⅛ inch / 3mm) or a very sharp chef's knife held at a consistent angle, slice the zucchini into rounds. If using a knife, work slowly and deliberately — uneven thickness is the primary reason home zucca chips turn out inconsistent, with some pieces overdone and others still raw and limp. The target thickness is thin enough that you can just barely see through a slice when held up to light, but not so fragile that it tears when dipped in batter. Lay the sliced rounds on a clean kitchen towel or paper towels in a single layer and press gently to absorb any surface moisture. Allow them to air dry for 5 minutes while you make the batter.

MAKE THE BATTER

Step 2 — Combine the dry ingredientsIn a medium mixing bowl, combine the all-purpose flour, cornstarch, baking powder, salt, pepper, and sugar. Whisk briskly for 30 seconds until everything is uniformly blended — uneven dry mixing means pockets of baking powder or cornstarch in the finished batter, which can produce uneven texture. Set this bowl aside.
Step 3 — Add the cold sparkling water and vinegar — do not overmixPour the cold sparkling water and the vinegar into the dry ingredient bowl. Use a fork or whisk to stir gently — 10 to 12 strokes only. The batter should be smooth but may have a few small lumps, and this is correct. The cardinal rule of tempura-style batters is that they must not be overmixed: overmixing develops gluten in the flour, which produces a thick, chewy, bready coating rather than the sheer, shattering crust you are after. The finished batter should be noticeably thinner than pancake batter — more like cream than a thick batter — and it should look visibly bubbly from the sparkling water. Use the batter immediately after mixing; as it sits, the carbonation dissipates and the gn develops, both of which reduce the crispiness of the finished chips.

FRY THE CHIPS

Step 4 — Heat the oil to the correct temperaturePour enough neutral frying oil into your heavy-bottomed pot or deep skillet to reach a depth of at least 1 inch — 1.5 inches is better for more consistent submersion. Place over medium-high heat and bring to 350°F (175°C), monitoring with your thermometer. This temperature is deliberate: higher than 375°F burns the delicate batter before the zucchini can heat through; lower than 325°F means the batter absorbs oil rather than immediately setting into a crust, producing greasy, limp chips. While the oil heats, set up your draining station: wire cooling rack set over a baking sheet, with the salt close at hand for immediate seasoning.
Step 5 — Dip, shake, and fry in small batches. Working with 5 to 8 zucchini rounds at a time (no more), dip each slice into the batter using tongs or your fingers, lift it out, and shake it firmly once or twice over the bowl to remove any excess batter — the coating should be thin and nearly translucent, not thick and gloopy. Lower the coated slice gently into the oil, laying it away from you to prevent splattering. The chip should immediately begin sizzling actively and floating toward the surface of the oil — this is the sign your oil is at the correct temperature. Fry for 2 to 3 minutes total, turning once about halfway through, until the chips are a uniform light golden color. Do not wait for deep golden-brown — the chips continue to cook and darken on the rack after being removed from the oil. Between each batch, allow the oil to return to 350°F before adding the next — this takes approximately 30 to 60 seconds. Overcrowding the pot drops the oil temperature dramatically and is the single most common cause of soggy, oil-saturated chips.
Step 6 — Drain on a wire rack and season immediatelyRemove each chip from the oil with tongs or a spider skimmer and transfer directly to the wire rack. Do not stack the chips. Give each one a light blot with paper towels if desired, then immediately — while each chip is still glistening hot — season generously with flaky sea salt. The salt applied to a hot chip adheres to the surface and becomes part of the flavor; salt added after the chip cools slides off and sits on the plate. The chips are ready to serve as soon as the current batch is seasoned — they are best within 5 minutes of coming out of the oil, while the batter is at its most shatter-crisp.
Step 7 — Serve immediatelyPile the chips on a warm plate or a shallow bowl lined with parchment and bring them to the table at once. At North Italia, they are served simply — a generous mound of golden chips, nothing else on the plate, with any dipping sauce offered on the side rather than poured over. This keeps the batter dry and crispy for as long as possible. Do not cover or tent the plate, which traps steam and softens the chips within minutes.

Notes

Cold sparkling water is the most important batter ingredient: The carbonation creates air bubbles throughout the batter that expand explosively when they hit the hot oil, producing a coating that is light, shatteringly crisp, and paper-thin rather than thick and bready. Use it straight from the refrigerator or chill it in a glass of ice water for 5 minutes before mixing. Never substitute still water — the texture difference is immediately and dramatically obvious.
Do not overmix the batter — ever: 10 to 12 gentle strokes is the absolute maximum. Overmixing develops gluten strands in the flour that make the coating dense, chewy, and thick. Lumps in the batter are not only acceptable — they are a sign you have not overmixed. The batter should look like thin cream with a few small lumps, not a smooth, uniform paste.
Oil temperature is your quality control: Below 325°F, the batter sits in the oil absorbing fat before it can set — resulting in a greasy, limp chip. Above 375°F, the batter browns and burns before the zucchini heats through. The ideal window is 350–365°F. If you do not have a thermometer, the wooden-spoon test is your guide: drop the handle into the oil and you should see a moderate, steady stream of small bubbles — not a violent boil, not silence.
Season immediately or not at all: Salt applied to a cold chip does not adhere — it sits loose on the surface and falls into the serving bowl. Salt applied the instant the chip comes off the rack adheres to the hot batter surface and becomes genuinely part of the chip. Have the salt in your hand before the first batch is done.
A wire rack is not optional: Draining on paper towels alone traps steam against the underside of the chip, softening it within 2 minutes. A rack elevates the chip so air circulates on all sides, keeping every surface crispy for much longer. Place paper towels under the rack to catch drips, but the chip must sit on the rack, not on the towel.
How to know when the oil is ready without a thermometer: Drop a small piece of zucchini skin or a tiny drop of batter into the oil. At 350°F, it should immediately sizzle, rise to the surface within 2 seconds, and begin frying steadily without violent splattering. If it sinks and stays still, the oil is too cold. If it splatters violently and immediately darkens, the oil is too hot.
Variation — Parmesan dusted: While the chips are still hot from the oil and salted, immediately shower them with freshly grated Parmigiano Reggiano. The heat of the chip begins to melt the cheese onto the surface, adding a savory, nutty depth. This is a popular home adaptation that North Italia regulars have been requesting as a topping since the dish launched.
Variation — Lemon zest finish: Grate fresh lemon zest directly over the hot chips along with the salt. The aromatic oils in fresh lemon zest bloom on the hot surface and provide a bright, citrusy lift that cuts through the fried richness and makes the chips taste even lighter. A small squeeze of lemon juice — just a few drops — over the pile just before serving amplifies this effect.
Variation — Spicy Calabrian: Add ¼ teaspoon of Calabrian chili flakes or a tiny amount of finely minced Calabrian chili paste to the batter along with the dry ingredients. The heat of the chili blooms in the batter as it fries, producing a lightly spicy coating that makes the chips particularly good alongside a cold aperitivo.
Variation — Air fryer method: Coat the zucchini slices in a very thin layer of the dry ingredients only (skip the sparkling water and make a dry dredge instead), spray lightly with oil, and air fry at 400°F for 8 to 10 minutes, flipping halfway. The result is not identical to the fried version — the coating is thinner, more powdery, and less spectacular in crunch — but it is a significantly lighter option that is good in its own right.
Make-ahead tip: The zucchini can be sliced up to 8 hours in advance and stored in the refrigerator in a container lined with paper towels (the paper towels absorb released moisture). The dry batter ingredients can be pre-mixed and stored at room temperature. Do not pre-mix the complete batter — it must be made just before frying, as the carbonation and batter freshness are time-sensitive.
Storage: Fried zucca chips do not store or reheat well. They soften significantly within 30 minutes and become noticeably limp by the hour. For the best experience, fry only what will be eaten immediately. If leftovers are unavoidable, spread on a baking sheet in a single layer and reheat in a 350°F oven for 5 to 7 minutes — this restores some crispness but does not return them to their fresh-from-the-fryer state. Never microwave.
Scaling note: Each large zucchini yields approximately 25 to 35 rounds. Two zucchini serves 4 as a generous appetizer. For a party of 8, use 4 zucchini and double the batter. Fry in sequential batches rather than all at once, and serve each batch immediately as it comes out of the oil rather than holding all chips until the end.
