Crispy Homemade Air Fryer French Fries (Russet Technique)
Cold-water soak + double-fry method for steakhouse-crispy fries.
Method · 10 steps
- 1
Cut russets into even 1/4-inch-thick fries (don't peel — the skin crisps up beautifully).
- 2
Submerge fries in a bowl of ice-cold water for 10-15 minutes. Change the water once if it gets cloudy — this pulls out starch that otherwise makes fries gummy.
- 3
Drain fries and spread on a clean kitchen towel. Pat EXTREMELY dry — any surface water will steam them.
- 4
Transfer dry fries to a large bowl. Sprinkle with cornstarch and toss until every fry has a light dusty coating.
- 5
Drizzle with avocado oil, salt, garlic powder, paprika, and pepper. Toss until evenly coated.
- 6
Preheat the air fryer to 325°F for 3 minutes.
- 7
Par-cook at 325°F: spread fries in a single layer (work in two batches if needed) and cook 10 minutes, shaking the basket at 5 minutes. Fries should look pale, tender, and slightly dry — no color yet.
- 8
Crank temperature to 400°F. Cook fries 8-10 more minutes, shaking at 4 minutes and 7 minutes. Watch closely from minute 8.
- 9
Fries are done when deep golden brown and crispy-sounding when the basket rattles. If they're still pale, give them 2 more minutes.
- 10
Immediately transfer to a bowl lined with paper towels. Toss with a big pinch of finishing salt while they're still piping hot — the salt sticks to hot surfaces only.
Chef's notes
- →Two temperatures is what separates amateur fries from crispy fries. Low first to cook the inside, high to crisp the outside.
- →Cornstarch dusting is the secret from restaurant kitchens — creates a crackly outer shell in under 10 minutes.
- →Soak in ice water, pat bone dry. Wet fries steam in the air fryer and never crisp — this is the #1 home-cook mistake.
Storage
Best fresh. Leftover fries re-crisp at 400°F for 3-4 minutes (never microwave — they turn limp).
