Belgian-Style Air Fryer Frites

The secret to authentic Belgian fries (frites) lies in a two-stage cooking process and achieving the right internal texture. Traditionally this means double-frying in beef tallow (blanc de bœuf). Replicating it in an air fryer is a challenge, because air fryers dry out the surface of food through convection rather than flash-sealing it with hot oil. With a starch-building par-boil and a two-stage fry, though, you can get incredibly close.

  • Time: About 1 hour
  • Difficulty: Medium
  • Serves: 2-3

Ingredients

  • 800g floury potatoes (Maris Piper or Russet), cut into 1-1.2cm thick batons
  • 1 tbsp white vinegar
  • 1 generous pinch salt (for the par-boil water)
  • 1-2 tbsp high-smoke-point oil (duck fat or melted beef tallow for the most authentic flavour, or peanut or vegetable oil)
  • Fine sea salt, to finish

Method

1. Cut and rinse

  1. Cut the floury potatoes800g floury potatoes (Maris Piper or Russet), cut into 1-1.2cm thick batons into thick batons, about 1-1.2cm thick. Authentic Belgian frites are never shoestrings.
  2. Rinse thoroughly in cold water to remove excess surface starch, until the water runs completely clear.

2. The acid par-boil

  1. Place the fries in a pot of cold water and add the vinegar1 tbsp white vinegar and a generous pinch of salt.
  2. Bring to the boil and simmer for exactly 8-10 minutes, until the edges are slightly soft but the interior still holds its shape.
  3. Drain thoroughly.

☘ Tip

Par-boiling with a touch of vinegar1 tbsp white vinegar structurally strengthens the pectin on the outside of the potato, preventing it from breaking apart, while drawing out loose starches to create a textured surface that crisps up beautifully in circulating air.

3. Rough up and dry

  1. Return the drained potatoes to the warm pot and give them a gentle shake to rough up the edges slightly — this creates micro-texture for extra crispness.
  2. Spread them out on a clean tea towel or cooling rack and let them air-dry completely. They must be dry to the touch before entering the air fryer.

4. The fat coat

  1. Toss the dry potatoes in a bowl with the oil.
  2. Ensure every baton is thinly but evenly coated.

5. Stage 1: the blanching fry

  1. Air fry at 160°C for 15 minutes to cook the potato through without browning the outside, shaking the basket every 5 minutes.
  2. They should look pale, dry, and slightly blistered, but not yet golden.
  3. Take them out and let them rest for 5 minutes.

6. Stage 2: the crisp fry

  1. Crank the air fryer up to 200°C and return the fries to the basket.
  2. Air fry for 10-12 minutes, until deeply golden brown and audibly crispy when shaken.
  3. Toss immediately with fine sea saltFine sea salt, to finish.

☘ Tip

The crowding rule: Do not overload the air fryer basket. If the batons are piled three layers deep, they will steam instead of fry, leaving you with soggy edges. Work in batches if making a large portion.
