Extra-Crunchy Spiral Potato Fries Step-by-step instructions

Before you start

Before starting, ensure the potatoes are boiled and peeled, and measure out all ingredients. Set up a frying station with a deep skillet or Dutch oven, a slotted skimmer, and a paper towel-lined tray for draining.

Have a kitchen thermometer ready to monitor the oil temperature. It's also helpful to shape all the spirals before heating the oil, so frying goes quickly and smoothly. Keep the dough covered with a damp cloth if shaping takes a while to prevent it from drying out.

Instructions

Mash and Season

1. 1Mash the potatoes
   Place the boiled yellow potatoes in a large glass dish or mixing bowl. Mash them thoroughly with a potato masher until completely smooth and lumpless, with a creamy, uniform texture. Make sure there are no remaining chunks, as they will create uneven fries.
   Look for The potatoes should look like a smooth, dense puree with no visible lumps.
   Tip Mash while the potatoes are still warm for the smoothest result; cold potatoes tend to stay lumpy.
2. 2Season the dough
   Add the cornstarch, kosher salt, and black pepper to the mashed potatoes. Use a wooden spoon or your hands to knead everything together until a soft, pliable dough forms. The dough should be smooth, slightly tacky, and hold together without cracking.
   Look for The dough comes together into a soft ball that doesn't stick to your hands.
   Tip If the dough feels too wet, add a little extra cornstarch; if too dry, a drop of water helps.
3. 3Shape the spirals
   Pinch off a small portion of the dough and roll it between your palms into a thin rope about 1/2 inch thick. Twist the rope into a tight spiral or curl, pressing the ends to seal. Repeat with the remaining dough, spacing the spirals on a clean surface.
   Look for Each spiral is uniform in thickness and holds its shape without unraveling.
   Tip Keep the spirals small so they fry evenly and become crunchy all the way through.

At the end of this phase, you should have a smooth, lump-free potato puree that has been seasoned and kneaded into a soft, pliable dough. The dough should be easy to shape and hold together without cracking. When you pinch off a piece and roll it into a rope, it should feel smooth and slightly tacky. The spirals should hold their shape and not unravel. This is the foundation for the perfect fry.

Fry to Golden Crisp

4. 4Heat the oil
   Pour the vegetable oil into a deep skillet or Dutch oven, filling it no more than halfway. Heat over medium-high until the oil reaches 350°F (175°C). Use a kitchen thermometer to check the temperature, or drop a tiny piece of dough into the oil—it should sizzle immediately and rise to the surface.
   Look for The oil shimmers and a dough scrap sizzles and bubbles vigorously on contact.
   Tip Maintain the oil temperature between 325°F and 350°F for the crispiest result.
5. 5Fry the spirals
   Carefully lower a few spirals into the hot oil, working in batches to avoid crowding. Fry for 2 to 3 minutes, turning occasionally, until golden brown and blistered all over. The outer surface will crisp into crunchy ridges while the inside stays tender.
   Look for The fries turn deep golden brown and make a crisp crackling sound as they fry.
   Tip Do not overcrowd the pan; fry in small batches to keep the oil temperature steady.
6. 6Drain the fries
   Use a slotted skimmer to scoop the fried spirals out of the oil, letting excess oil drip back into the pan. Transfer them to a tray lined with paper towels or newspaper to drain. Continue frying the remaining batches the same way.
   Look for The fries are crisp, golden, and make a clinking sound as they tumble onto the tray.
   Tip Drain on paper towels to absorb excess oil and keep the crust shatteringly crisp.

The oil should be shimmering and at the right temperature, and the fries should be frying in small batches. You'll see them turn golden brown and blister, with a satisfying crackling sound. When you scoop them out, they should be crisp and dry, not greasy. The tray will fill with golden spirals that make a clinking sound as they land. The kitchen will smell of warm, fried potatoes—irresistible.

Pile High and Serve

7. 7Pile and serve
   Once all the fries are fried and drained, pile them high in a paper-lined serving basket or on a platter. Serve immediately while they are hot and at their crunchiest. The contrast between the crisp exterior and the soft, pillowy interior is the highlight.
   Look for The fries are piled high, steam rising, with a loud crunch when broken.
   Tip Serve right away—these fries lose their crunch as they cool.

The finished fries are piled high on a paper-lined serving basket, steam rising from the golden spirals. When you break one in half, it snaps with a loud crunch, revealing a soft, tender interior.

The contrast is perfect: shatteringly crisp outside, pillowy inside. Serve immediately while they are at their peak crunchiness. The visual and auditory appeal is undeniable—these fries are ready to impress.

Common mistakes

One common mistake is overworking the dough, which can make it tough. Mix just until the ingredients come together. Another pitfall is frying at too low a temperature, which results in greasy, soggy fries. Keep the oil hot and fry in small batches.

Similarly, overcrowding the pan drops the oil temperature and leads to uneven cooking. Finally, don't skip the cornstarch—it's the key to that extra-crunchy crust. If the dough is too wet, add a little more cornstarch; if too dry, a tiny splash of water helps.

How to tell it’s done

The fries are done when they are deep golden brown and blistered all over, with a crisp, crackling sound when tapped. The internal texture should be tender and fluffy, with no raw potato taste.

To check, break one open—the center should be soft and steamy, while the crust shatters easily. Since there are no raw proteins in this recipe, no internal temperature check is needed. Serve immediately for the best crunch.
