Crispy on the outside, soft and fluffy on the inside — that’s the gold standard for perfect French fries. Traditionally, deep frying was the only way to get that irresistible crunch. But with the rise of air fryers, you can now enjoy guilt-free fries with the same satisfying texture and flavor — minus the mess and excess oil.
Here’s how to make perfectly crispy French fries in an air fryer, every single time.
Air fryers work by circulating hot air rapidly around the food, mimicking the crispy results of deep frying but using up to 90% less oil. The result? Healthier fries that are golden brown and delicious — with no greasy aftertaste.
Russet potatoes are ideal because they have a high starch content and low moisture — perfect for crisping up. Wash, peel (if desired), and cut them into even sticks, about ¼ to ½ inch thick.
Soaking is the secret to restaurant-style fries. Place the cut potatoes in cold water for at least 30 minutes (up to 2 hours). This removes excess starch and helps them crisp up beautifully.
After soaking, drain and pat the fries dry with a clean towel. Moisture is the enemy of crispiness in the air fryer.
Toss the dry fries in a bowl with 1–2 tablespoons of oil and your chosen seasonings. Don’t skip the oil — it helps with browning and enhances flavor.
Some air fryers don’t need preheating, but if yours does, set it to 375°F (190°C) for 3–5 minutes.
Spread the fries in a single layer in the basket. Avoid overcrowding, or they’ll steam instead of crisp. Cook in batches if necessary.
Cook at 375°F (190°C) for 15–20 minutes, shaking the basket every 5 minutes for even browning. Cooking times can vary by model and fry size, so keep an eye on them in the last few minutes.
As soon as they come out, toss with a little extra salt or finishing seasoning if desired. Serve hot for the best taste and texture.
