Ingredients

• 3 medium potatoes (about 500 g); starchy varieties like the regular Indian aloo or Russet work best
• 1 tbsp oil (sunflower, rice bran or groundnut)
• 1 tsp cornflour (optional, for extra crunch)
• Salt to taste
• Optional seasoning: peri-peri, chaat masala, black pepper, or red chilli and amchur for masala fries

How to make French fries in the air fryer

1. Cut. Peel (or scrub) the potatoes and cut into even 1 cm-thick sticks.
2. Soak. Soak in cold water for 30 minutes (or up to 2 hours). This rinses off surface starch so the fries crisp instead of sticking and going gummy.
3. Dry completely. Drain and dry thoroughly with a clean kitchen towel. This is the most important step.
4. Coat. Toss with oil, then cornflour if using, so every fry has a thin even coat.
5. Air fry. Preheat to 200 °C (400 °F). Add the fries in a loose, nearly single layer and cook for 15–20 minutes, shaking every 5–6 minutes, until deep golden.
6. Season immediately with salt and your choice of masala while hot.

Masala fries (desi style)

Toss hot fries with ½ tsp chaat masala, ¼ tsp kashmiri chilli powder, ¼ tsp amchur and a pinch of black salt. Or go peri-peri: ½ tsp each of chilli flakes, garlic powder and oregano, with a pinch of sugar and salt.

Why soak the potatoes? (crispness and acrylamide)

Soaking does two jobs. It washes off surface starch, so the fries crisp instead of turning gummy, and it reduces acrylamide — a compound that forms when starchy foods are cooked at high heat. The US FDA advises soaking raw potato slices in water for 15–30 minutes before frying or roasting, and cooking them to golden yellow rather than dark brown, because brown areas contain more acrylamide. It also recommends storing potatoes in a cool, dark place rather than the fridge.

Air fryer fries vs deep-fried: the oil difference

This recipe uses 1 tablespoon of oil for about 500 g of potatoes. One tablespoon of cooking oil is roughly 120 kcal and 14 g of fat (USDA FoodData Central), shared across 2–3 servings. Deep frying submerges the fries in oil, and they absorb far more of it. For a side-by-side look, see air fryer vs deep fryer and is an air fryer healthy?

Tips

• Don’t skip the soak. It’s the difference between crisp and limp.
• Batch cook. For 4 people, do two batches and re-crisp the first for 2 minutes before serving.
• Want restaurant-crisp? Par-boil the soaked fries for 3 minutes, dry, then air fry.
• Still soggy? See why are my air fryer chips not crispy?

Frequently asked questions

How long do French fries take in the air fryer?

15–20 minutes at 200 °C (400 °F) for 1 cm fries, shaking every 5–6 minutes.

Do I need to soak potatoes before air frying?

Yes, for the crispiest fries. 30 minutes in cold water removes surface starch. If short on time, at least rinse them well and dry thoroughly.

Can I make fries without oil?

You can, but they’ll be dry and pale. A tablespoon for 500 g of potatoes makes a big difference.
