One tablespoon of oil for one kilo of potatoes, and the rest is soaking and the right sequence. Homemade french fries from the air fryer get truly crispy on the outside if you wash off the surface starch beforehand and cook them in two temperature stages. Without these two steps, they become leathery.
Why this works
When cutting, starch escapes from the damaged cells to the surface. In the appliance, it gelatinizes into a tough, glassy layer that prevents water from escaping, and the result is leathery on the outside and steamy on the inside. Thirty minutes in cold water washes off this starch, and that is the biggest single lever of the whole recipe. The second rule is the two-stage process. At 160 °C, the potato cooks through on the inside and loses water without the surface browning yet. Only then does the second stage at 200 °C bring the dry surface over the roasting threshold. Conversely, if it were hot right away, the crust would be done before the core is cooked. And the basket must only be two-thirds full because the air must circulate between the sticks. A full basket is a steamer.
Step-by-step instructions
- 1
Cut and soak
Peel the potatoes and cut them into even sticks with an edge length of about one centimeter. Place them in cold water for thirty minutes. The water becomes visibly cloudy, and exactly this starch is the reason for leathery fries.
- 2
Pat really dry
Drain the sticks and dry them thoroughly with a kitchen towel. Residual water turns into steam in the appliance, and steam is the opposite of crust. Only then mix with the oil and paprika powder until all sticks shine.

First stage: 160 °C
Put the fries in the basket, filled to a maximum of two-thirds, and cook them for fifteen minutes at 160 °C. They are pale and soft afterwards, which is exactly right. In this phase, the potato loses water without the surface closing yet.
- 4
Second stage: 200 °C
Turn up to 200 °C and give another eight to ten minutes, shaking vigorously twice. Now they brown quickly. Salt only afterwards, because salted beforehand, the fries draw water and become soft.
Our best tips
- The thirty minutes of soaking are the biggest lever. Without it, the surface starch gelatinizes and the fries become leathery instead of crispy.
- Fill the basket only two-thirds full. The air must circulate between the sticks, because a full basket is a steamer with a fan.
- Salt only at the end. Salted beforehand, it draws water to the surface and works against everything you just did.
Tasty variations
In the oven
At 220 °C convection on a hot tray, twenty minutes, turning halfway through. Also possible in two stages, but the crust remains thinner, because the oven lacks the air speed.
Sweet potato fries
Sweet potatoes contain less starch and more sugar. Do not soak, but fold in one tablespoon of cornstarch and cook at 180 °C in one stage for fifteen minutes. Otherwise, the sugar browns too early.

Calculated from the ingredients – how we do it
We add up reference values for every ingredient and divide by the number of servings. These assumptions are baked in:
- Reference values per 100 g – for the raw ingredient, exactly as listed.
- Tinned goods count at drained weight, bone-in meat at purchase weight: you eat about 70 per cent of a chicken thigh and leave the rest.
- Water evaporates as you cook. The energy stays in the pot, the weight does not – so the figure is per serving, not per 100 g of finished dish.
- Anything listed without a quantity – “salt and pepper” – is not counted.
A guide value, not a lab measurement: no two onions weigh the same, and fat content varies from pack to pack.
Frequently asked questions
Which potatoes are best?
Mostly waxy ones. Waxy ones have too little starch for a fluffy interior, and floury ones fall apart at the edges. If only floury ones are available, shorten the soaking to fifteen minutes, because they release a lot of starch anyway.
Can I prepare the fries in advance?
Yes, up to the first stage. After the fifteen minutes at 160 °C, let them cool down and refrigerate for up to a day. The second stage then only takes eight minutes, so when eating for guests, everything is ready in eight minutes instead of twenty-five.
Why do my fries get soft as soon as they are on the plate?
They are lying too close together or on a plate under which steam accumulates. After cooking, briefly place on a wire rack or a kitchen towel, do not stack, and eat immediately. A french fry keeps its crust for about five minutes, which is not a question of preparation.
