Fries are arguably what the air fryer does best. You get crispy, golden results with a fraction of the oil used in deep frying, and they cook significantly faster than oven-baked fries. The trick is not overcrowding the basket — air needs room to circulate for that signature crunch.
Below you will find exact conversion times for every type of fry, from fresh-cut russet to frozen sweet potato. All times assume a preheated air fryer and a single layer of fries with space between them.

|---|---|---|---|---|---|
| Fresh-cut (thin) | 425°F | 400°F | 25 min | 15 min | Soak in water 30 min, pat dry. Shake at 8 min. |
| Fresh-cut (thick) | 425°F | 400°F | 30 min | 20 min | Thicker cuts need longer. Shake twice. |
| Frozen thin fries | 425°F | 400°F | 20 min | 14 min | No oil needed. Shake at 7 min. |
| Frozen thick/steak | 425°F | 400°F | 25 min | 18 min | Shake halfway. May need extra 2 min. |
| Sweet potato fries | 400°F | 375°F | 25 min | 16 min | Light oil. Burns faster — watch closely. |
| Curly fries (frozen) | 425°F | 400°F | 18 min | 12 min | Single layer. Shake at 6 min. |
| Wedges | 400°F | 375°F | 30 min | 20 min | Flip halfway. Season before cooking. |
Soak fresh-cut fries — Soaking raw potatoes in cold water for 30 minutes removes excess starch, which is the secret to restaurant-level crispiness.
Dry thoroughly — After soaking, pat fries completely dry. Moisture is the enemy of crispiness.
Light oil toss — Just 1–2 teaspoons of oil tossed with fresh fries promotes browning. Frozen fries already have oil and usually don't need more.
Single layer, shake often — This is the most important rule. Overcrowding steams fries instead of crisping them. Shake or toss the basket every 5–7 minutes.
