Air Fryer French Fries From Scratch
Crispy air fryer fries made from raw Russet potatoes using a two-temperature method — a low run to cook the interior through, then a high blast to shatter the crust. The cold-water soak and aggressive drying step are what separate these from fries that look golden but bend.

Most air fryer fry recipes skip two things that actually matter: a proper soak and a complete dry. This version does both — and uses a two-temperature cook to guarantee a centre that is cooked through before the outside seizes. The result is a fry that holds its crunch past the first minute on the plate.
Worth Knowing Before You Cook
After the 30-minute soak, the fries must be bone-dry to the touch before the oil goes on. Any residual surface moisture creates a “steam jacket” inside the basket that prevents the starch from shattering when you bite in — even a small amount of dampness will produce a flexible, tough fry rather than a crisp one. Pat with a lint-free towel, then leave the sticks on the towel for two minutes before oiling; that extra air-dry step makes a visible difference.
Ingredients
Equipment
Method
- Peel and cut the potatoes into 1cm thick sticks, keeping cuts as uniform as possible.
- Soak the cut sticks in a large bowl of cold water for 30 minutes.
- Drain the potatoes and pat thoroughly with a lint-free towel until completely dry. Leave the sticks on the towel for a further 2 minutes to air-dry before oiling.
- Toss the dried sticks in a bowl with 1 tablespoon of oil until every surface is lightly coated.
- Preheat the air fryer to 160°C (320°F) for 3 minutes with the basket empty.
- Arrange the fries in a single layer in the preheated basket — do not stack or overlap.
- Air fry at 160°C (320°F) for 15 minutes to cook the interior through without browning the outside.
- Shake the basket firmly to redistribute the fries.
- Raise the temperature to 195°C (385°F) and air fry for 12 minutes, shaking every 4 minutes, until deep golden brown and audibly crisp when tapped.
- Season immediately with 1/2 teaspoon fine sea salt while the surface oil is still hot so the salt adheres.
Notes
Why This Recipe Works
Soaking draws out the simple sugars that would burn before the centre cooks through, and drying completely before oiling means the starch gelatinises in dry heat rather than steam — which is the difference between a crust that shatters and one that flexes.
- A 30-minute cold soak removes excess surface starch and simple sugars that would scorch at high heat.
- A two-temperature cook — 160°C (320°F) then 195°C (385°F) — guarantees the interior is cooked through before the crust sets.
- Preheating the basket before loading means the fries hit dry heat immediately, not a cold surface warming up around them.
Pro Tips
- After towel-drying, leave the sticks on the towel for a further 2 minutes before oiling — that air-dry window makes a visible difference to the final crust.
- Use Russet or Sebago potatoes only. Waxy varieties (Kipfler, Dutch Cream) have too little starch and produce a dense, pithy result.
- A single layer in the basket is non-negotiable. If your air fryer is smaller than 6L, cook in two batches rather than stacking.
- Season immediately out of the basket while the surface oil is still hot — salt will not adhere once the fries cool.
What Can Go Wrong
If the fries are limp and soggy…
Surface moisture remained after soaking. Pat aggressively with a lint-free towel next time, then leave the sticks on the towel for 2 minutes before oiling. Even a small amount of dampness creates a steam jacket in the basket that stops the crust forming.
If the outside is dark but the centre is still raw…
The 160°C (320°F) softening phase was skipped or the temperature jumped to high heat too soon. The two-step method is not optional — the low phase is what cooks the interior through before the crust sets at high heat.
If the fries are pale and soft despite correct timing…
The preheat step was skipped. Step 5 is not optional — run the empty basket at 160°C (320°F) for 3 minutes before loading the fries. Fries placed into a cold basket start cooking unevenly before the element stabilises.
Storage & Reheating
Cool completely before storing — do not seal while warm or trapped steam will undo the crust. Keep in an airtight container in the fridge for up to 2 days.
To reheat, air fry at 190°C (375°F) for 3–4 minutes until sizzling and the crust has returned. Do not microwave — it reintroduces exactly the steam problem the drying step was designed to prevent.

FAQ
Do I really need to soak the potatoes?
Yes, if you want a proper crust. Skipping the soak leaves excess simple sugars on the surface that burn at high heat before the centre is cooked through. Thirty minutes is the minimum — longer does not hurt.
Can I use a different potato variety?
Russet and Sebago both work well. Avoid waxy varieties like Kipfler or Dutch Cream — their low starch content produces a dense, pithy fry that will not crisp properly regardless of temperature or timing.
Can I make a larger batch?
Yes, but cook in separate batches rather than stacking. A single layer is non-negotiable — overcrowding traps steam and prevents the crust from forming. If your basket is smaller than 6L, one large potato per batch is the practical limit.
