Transform your fries with a simple hot water trick
Coming home to a plate of soggy, undercooked fries from your air fryer can be disappointing. But fear not, because a simple hot water bath can work wonders and elevate your crispy fry game.
Why your fries often remain soft
Potatoes contain a high amount of starch, which clings to their surface when cut into batons. As they cook, this starchy coating forms a humid layer, preventing hot air from creating a crispy crust. The result? Fries that are slightly spongy and unappetizing.

The hot water magic that changes everything
Submerging your cut potatoes in hot water extracts the excess starch from their surface rapidly. The water will turn cloudy, but that's just the starch dissolving. After draining and drying, the surface will dry better in the air fryer, browning and crisping up beautifully on the outside while keeping the inside tender.
Recipe and step-by-step method
Total Time: Approximately 25-30 minutes
Trempage Time: 10-15 minutes
Ingredients and Materials:
- 600-800g Potatoes (Bintje, Agria, or Charlotte varieties) - 3-4 pieces
- 1 Liter Hot Water (70-80°C)
- 1-2 tablespoons Neutral Oil (Sunflower or Rapeseed)
- Salt, to sprinkle after cooking
- Clean Cloth or Paper Towels for drying
Instructions:
- Eyeball and slice potatoes into uniform batons, about 1 cm thick. Uniform pieces brown more evenly.
- Heat 1 liter of water to 70-80°C, not quite boiling.
- Soak the potato batons in the hot water for 10-15 minutes, until the water turns cloudy.
- Drain the potatoes carefully and pat each piece dry with a clean cloth or paper towels. Excess moisture hinders crispiness.
- In a bowl, toss the dried potatoes with 1-2 tablespoons of neutral oil to lightly coat.
- Preheat the air fryer to 180°C, if possible.
- Arrange the potatoes in a single layer in the air fryer basket, without overcrowding.
- Cook at 180°C for 15-20 minutes, shaking the basket halfway through for even browning.
- Remove, sprinkle with salt to taste, and serve hot.
Additional tips for even better fries
Never overcrowd the basket. Hot air needs to circulate freely for crisp results. Cook in batches if necessary.
Choose high-starch potato varieties for the best browning.
Season after cooking to prevent burnt spices.
Swap 1 tablespoon of neutral oil with an aromatic oil after cooking for extra flavor. A drizzle of garlic oil just before serving is divine.
Preheat the air fryer 2-3 minutes to help the crust form faster.
For exceptionally crispy fries, increase the temperature by 2-3°C at the end and monitor closely.
