Air fryer fries cook in 10–18 minutes at 380–400°F, based on cut, frozen vs fresh, and basket load.
If you’ve ever pulled fries out too pale or too dark, the clock usually isn’t the real problem. It’s the cut, the starting temperature, and how much air can move around each piece. Get those right and the timing gets steady.
This guide gives you reliable time ranges for frozen and fresh fries, plus a simple way to adjust when you change thickness, temperature, or batch size. If you only want one takeaway, start at 390°F, shake once, and plan on 12–15 minutes for most frozen “regular cut” fries.
Fries Cook Time In An Air Fryer By Cut
Use this table as your starting point. Times assume a single layer in a preheated basket with a quick shake halfway through. If you stack fries or crowd the basket, add time in small steps and shake twice.
| Fries type | Temp | Time range |
|---|---|---|
| Frozen shoestring | 390°F | 8–12 min |
| Frozen regular cut | 390°F | 12–15 min |
| Frozen crinkle cut | 390°F | 13–17 min |
| Frozen steak fries | 400°F | 16–22 min |
| Frozen waffle fries | 390°F | 10–14 min |
| Fresh-cut fries (¼ inch) | 380°F | 16–22 min |
| Fresh-cut thick fries (½ inch) | 370°F | 22–30 min |
| Sweet potato fries (frozen) | 380°F | 10–16 min |
Why cut size changes time so much
Thin fries cook fast because heat reaches the center quickly and surface moisture escapes early. Thick fries take longer since the inside needs more time to soften while the outside dries and browns.
Surface area also controls crispness. Shoestring fries have lots of surface, so they can turn crisp with less total time. Steak fries have less surface per bite, so they need more time to dry on the outside.
Frozen vs fresh starts on different footing
Most frozen fries are par-cooked. That means the inside is partly cooked already and the outside often has a light oil coating. In an air fryer, that head start shortens the cook time and helps browning.
Fresh potatoes start raw and wet. If you skip prep, you can end up with fries that look brown before the middle gets tender. A short soak and a good dry fix that.
How Long Do Fries Cook In Air Fryer? With Cut And Temperature
The honest answer is a time band, not one number. Air fryers run hot or mild, baskets vary in depth, and your fries may start icy cold or room temp. Use the steps below to lock in a repeatable routine.
Frozen fries timing routine
- Preheat the air fryer for 3–5 minutes.
- Add fries in a loose layer. A little overlap is fine, piles are not.
- Cook at 390°F for the time range in the table.
- Shake at the halfway mark. Tap the basket so stuck pieces break free.
- Finish in 1–2 minute bursts until the color and crunch match what you like.
Most frozen fries land in the 10–18 minute window. Shoestring fries sit at the low end. Steak fries sit at the high end. If your air fryer has a small basket, you may get better fries by cooking two smaller batches instead of one crowded batch.
If your fries start straight from the freezer, expect the first shake to look stiff and pale. That’s normal. After shaking, spread them again and keep cooking. Basket-style air fryers can run a bit faster than oven-style models, so check two minutes early the first time. Jot the final time down.
Fresh-cut fries timing routine
- Cut potatoes to an even size so they finish together.
- Soak in cold water for 20–30 minutes, then drain.
- Dry well with a towel. Wet fries steam and soften.
- Toss with 1–2 teaspoons oil per pound of potatoes, plus salt after cooking.
- Cook at 370–380°F, shaking every 6–8 minutes, until tender inside and crisp outside.
Fresh fries usually take 16–30 minutes, based on thickness and potato type. If you want a classic fry texture, start at 370°F to cook the center, then raise to 400°F for the last 3–5 minutes to tighten the outside.
Temperature choices that keep fries crisp
Air frying is a balancing act: you want moisture to leave the surface while the inside turns soft. Temperature changes the pace of both.
When 360–370°F makes sense
Use this range for thick, raw fries when you want a soft center. Lower heat gives the inside time to cook before the outside browns too far. It also helps when your fries have sugar on the surface, like some sweet potato cuts, since they color fast.
When 380–390°F is the sweet spot
This range fits most frozen fries and most reheats. It cooks fast without scorching the corners. If you only remember one setting, 390°F is a solid default.
When 400°F is your finishing move
High heat shines at the end. It drives off the last bit of surface moisture, which turns a “good” fry into a crunchy one. Use it after the fries are cooked through, not from the first minute.
Prep steps that change the clock
Small prep moves can shift cook time by several minutes. They also change texture more than any seasoning does.
Preheat or no preheat
Preheating shortens total cook time and improves browning, since the basket starts hot. If you skip it, add 2–4 minutes to the clock and plan on a paler first half of the cook.
Oil: how much is enough
Frozen fries often have oil already. Extra oil can drip and smoke, plus it can make fries feel heavy. For frozen fries, try no oil first. For fresh fries, a small amount helps crisping and keeps salt sticking later.
Soaking fresh potatoes
Soaking pulls some starch from the surface, which helps fries crisp instead of clumping. After soaking, drying is the real make-or-break step. Moisture on the outside turns into steam inside the basket.
Seasoning timing
Salt draws moisture. If you salt raw fries, you can slow browning and soften the surface. Salt right after cooking, then toss. Dry spices like paprika, garlic powder, or chili powder can go on after cooking too, so they don’t burn at the edges.
For a quick food-safety and browning reference, the FDA’s acrylamide and diet guidance notes that darker browning can raise acrylamide levels in starchy foods such as potatoes. Aim for a golden color rather than a dark one.
Doneness checks you can trust
Timers get you close. Your senses finish the job. Use two checks and you’ll stop guessing.
Color check
For classic fries, look for light gold with a few deeper spots on corners. If the fries are still pale and matte, they’re not crisp yet. If they’re dark brown across broad areas, pull them and shorten the next run.
Sound and feel check
Shake the basket. Fries that are crisp sound dry and rattle. Soft fries sound dull and stick together. Also pinch one fry with tongs: a crisp fry resists a little, then snaps. A soft fry bends.
One-bite center check
For thick fries, taste one from the middle of the basket. If the center feels chalky, cook 3–4 more minutes at 370–380°F, then finish hot. If the center is soft, push heat up and chase crunch.
Common problems and fast fixes
If your fries miss the mark, it’s nearly always airflow, moisture, or temperature. Fix the cause and your next batch improves right away.
| Problem | What’s causing it | Fix |
|---|---|---|
| Soggy fries | Basket packed tight, moisture trapped | Cook in smaller batches; shake twice |
| Burnt corners, pale centers | Heat too high from the start | Start at 370°F, finish at 400°F |
| Uneven browning | Fries piled or not shaken | Shake halfway; spread into a looser layer |
| Fries stick together | Wet surface starch | Soak then dry; toss with a little oil |
| Dry, tough fries | Cooked too long at high heat | Lower temp by 10–20°F; pull earlier |
| Soft sweet potato fries | Sugars brown before moisture leaves | Use 375–380°F; cook longer, shake more |
| Smoke or burnt smell | Oil dripping onto hot surface | Skip extra oil; clean basket and tray |
| Salty outside, bland inside | Salt added too early | Salt right after cooking, then toss well |
Batch cooking and holding fries for a crowd
Air fryers are built for airflow, not volume. If you’re feeding more than two people, plan on two to four batches. The trick is keeping early batches crisp while the last batch cooks.
Set your oven to 200°F and place a wire rack on a sheet pan. Lay finished fries on the rack in a single layer. The rack keeps steam from pooling underneath, so the fries stay crisp. Keep them warm for up to 20 minutes, then serve.
If you don’t want to use the oven, leave finished fries in the air fryer basket with the heat off and the drawer cracked open. That vents steam. It won’t hold as long as the rack method, yet it buys you a few minutes per batch.
Seasoning ideas that suit air-fried fries
Air-fried fries have a drier surface than deep-fried fries, so seasoning sticks best right after cooking. Toss in a bowl, not in the basket, so spices coat evenly.
- Classic: salt and black pepper.
- Steakhouse: smoked paprika, garlic powder, pinch of sugar, then salt.
- Herb: dried oregano, parsley, lemon zest, then salt.
- Spicy: chili powder, cumin, pinch of cayenne, then salt.

Reheating leftover fries in the air fryer
Leftover fries can come back to life. Skip the microwave. Use a hot air fryer and a short cook.
- Preheat to 380°F for 3 minutes.
- Spread fries in a loose layer.
- Cook 3–6 minutes, shaking once, until hot and crisp.
Thick fries may take 6–8 minutes. Shoestring fries can go from crisp to dry fast, so check at 3 minutes. If fries were stored with a lid tight on, they may hold extra moisture. Add a minute and shake twice.
