AIR FRYER 101
Air Fryer French Fries: Frozen Bag or Fresh-Cut, Crispy Every Time
Frozen fries at 400°F with zero added oil, fresh-cut russets that beat the drive-thru, a time chart for every cut, and the shake rule that makes all of it work.
French fries are the air fryer's signature move — the dish that has sold more baskets than every other recipe combined. Frozen fries come out crispier than a sheet pan could ever manage, with no added oil and no preheating a 425°F oven in the middle of summer.
Below: the frozen-bag method (the easy win), a time chart by cut, real fresh-cut fries from russet potatoes, the two rules that decide crispy versus soggy, and how to bring last night's takeout fries back from the dead.
Frozen french fries in the air fryer: the easy win
Frozen fries were par-fried in oil at the factory, which is why they need nothing from you but heat. Step 1 — Preheat the air fryer to 400°F for 2 to 3 minutes. Step 2 — Add the frozen fries straight from the bag in a single layer; no thawing, no oil. Step 3 — Cook 10 to 15 minutes depending on the cut, shaking the basket at the 5-minute mark and again around 10. Step 4 — Go until deep golden, not pale yellow — the color difference is the flavor difference.
Salt after cooking, not before. Salt won't stick to a frozen surface, and whatever doesn't stick ends up scorched on the bottom of the drawer. Shake the hot fries with salt in a bowl and they're coated evenly in seconds.
Frozen fry times by cut: crinkle, waffle, steak, shoestring
All at 400°F, shaking twice: shoestring and other thin cuts take 8 to 10 minutes, regular straight-cut fries take 10 to 13, crinkle cut takes 12 to 15, waffle fries take 12 to 15, and thick steak fries take 14 to 16. Seasoned or batter-coated fries crisp fastest for their size — start checking those around 10 minutes.
Treat every number as a starting point. Wattage, basket size, and how full you load it all move the time, so check two minutes before the low end on your first bag of a new cut. Ignore the oven directions on the bag entirely — the air fryer runs faster and needs no preheated sheet pan.
Fresh-cut french fries from russet potatoes
Step 1 — Cut russets into quarter-to-half-inch sticks, skin on. Russets are the fry potato: high starch, low moisture, fluffy interior. Step 2 — Soak the cut fries in cold water for 30 minutes to pull surface starch, which is what separates crisp fries from gummy ones. Step 3 — Drain and dry them completely with a towel; wet fries steam. Step 4 — Toss with about a tablespoon of oil per two potatoes, plus salt.
Step 5 — Air fry at 380°F for 15 to 18 minutes, shaking every 5, working in batches if needed. Step 6 — Finish at 400°F for the last 2 to 3 minutes to set the final crisp. If you cooked in batches, dump everything back in together for the finishing blast so the whole pile lands on the table hot.
The two rules: shake the basket, keep a single layer
The shake rule: at least twice per cook, three times for fresh-cut. The fries pressed against the basket floor and the ones buried in the middle are living in different climates, and shaking rotates everyone through the good seats. Skipping the shake is the number one reason for half-crispy, half-limp results.
The single-layer rule: piled fries steam each other, and steam is the enemy. A little overlap is fine for frozen fries, but fresh-cut fries want one true layer with air between them — cook two batches rather than one bad one. And season over a bowl, never over the basket: stray oil and salt burn onto the drawer below and mean you have to clean your air fryer far more often than anyone wants.
How to reheat fries in the air fryer
Leftover fries are where the air fryer performs an actual miracle. Spread them in a single layer, air fry at 350°F for 3 to 4 minutes, and shake once — they come back shockingly close to fresh, with none of the microwave's steamed-cardboard texture. No oil needed; a quick spray helps only if the fries were sad and dry to begin with.
Thick steak fries and waffle cuts may want an extra minute. Just don't wander off — reheating rides the line between revived and burnt, and the window is about 60 seconds wide.
Seasoning upgrades and what to serve them with
Once plain salted fries are automatic, upgrade: garlic powder, smoked paprika, and salt is the house blend; grated parmesan and parsley tossed on hot fries is the fancy one; cajun seasoning is the one people ask about. Add cheese and delicate herbs after cooking so they melt and cling instead of burning.
Fries want a main, and the basket has one ready: air fryer chicken tenders come out of the same machine in about 12 minutes, so run the fries first and let them rest while the tenders cook. Every time in this guide assumes a basket-style unit like the Ninja air fryer; oven-style models tend to run a minute or two longer.

How long do you cook frozen french fries in an air fryer?
10 to 15 minutes at 400°F for most cuts, shaking twice: 8 to 10 minutes for shoestring, 10 to 13 for regular cut, 12 to 15 for crinkle and waffle, 14 to 16 for steak fries. Cook until deep golden and salt after.
Do you need oil for frozen fries in the air fryer?
No. Frozen fries were par-fried at the factory and already carry the oil they need. Straight from the bag to the basket, 400°F, done.
What temperature is best for french fries in an air fryer?
400°F for frozen fries. For fresh-cut, run 380°F for most of the cook so the inside gets fluffy, then finish at 400°F for the last 2 to 3 minutes to crisp the outside.
Why are my air fryer fries soggy?
Almost always overcrowding or under-shaking — piled fries steam each other. For fresh-cut fries, add two more culprits: skipping the 30-minute cold-water soak and not drying the potatoes completely before oiling.
Can you make homemade french fries in an air fryer?
Yes. Cut russets into quarter-to-half-inch sticks, soak in cold water 30 minutes, dry completely, toss with a light coat of oil, then air fry at 380°F for 15 to 18 minutes with a 400°F finish for the final 2 to 3.
How do you reheat french fries in an air fryer?
350°F for 3 to 4 minutes in a single layer, shaking once. They come back crisp instead of chewy — the microwave can't compete.
