Making french fries in air fryer baskets gives you that crave-worthy combination of a crisp, golden exterior and a fluffy interior using only a fraction of the oil deep frying requires. With the right potato, a quick soak, and the proper temperature, homemade air fryer fries rival anything from a drive-through—without the greasy aftermath or the giant pot of hot oil. This guide walks you through every step, from choosing and cutting the potatoes to seasoning, timing, and keeping batches crisp.

Air fryers are essentially compact convection ovens: a heating element and a powerful fan circulate very hot air around the food, browning the surface quickly while the inside cooks through. Because the air does the work, you need only a light coating of oil to get a satisfying crunch. If you are shopping for a machine, our roundup of the best air fryers for every kitchen and budget covers basket and oven styles in detail.

Choosing the Right Potato

The potato variety matters more than almost anything else. Russet potatoes are the classic choice because they are high in starch and low in moisture, which produces fluffy insides and crisp edges. Yukon Golds work well too and have a slightly buttery, creamy texture, though they brown a touch faster. Waxy potatoes like red or new potatoes hold together but never get as crisp, so they are best reserved for roasting.

Plan on roughly one medium russet (about 8 ounces) per person as a side. For an alternative root vegetable that crisps beautifully, see our dedicated guide to air fryer sweet potato fries.

Ingredients

  • 2 large russet potatoes (about 1 pound)
  • 1 to 1.5 tablespoons neutral oil (avocado, canola, or vegetable)
  • 3/4 teaspoon fine salt
  • 1/2 teaspoon garlic powder (optional)
  • 1/4 teaspoon black pepper or paprika (optional)

How to Cut Even Fries

Uniform sticks cook evenly, so take a minute to cut carefully. Slice each potato lengthwise into planks about 1/4 to 3/8 inch thick, stack the planks, and cut them into matchsticks of the same width. You can leave the skin on for extra texture and nutrients or peel it—both work. Thinner fries crisp faster but can burn; thicker fries stay fluffier inside but take longer. Aim for consistency above all.

The Soak: The Secret to Crispiness

Soaking cut potatoes in cold water for 30 minutes (or up to a few hours) rinses away surface starch that would otherwise cause fries to stick together and brown unevenly. After soaking, this is the step most people skip and then wonder why their fries turned out soft: dry the fries thoroughly. Pat them between clean kitchen towels or paper towels until no moisture remains. Surface water turns to steam and prevents crisping, so dry potatoes are essential.

Step-by-Step Air Frying

  • Step 1 — Season: Toss the dried fries in a bowl with the oil and salt until every stick is lightly and evenly coated. Use just enough oil to make them glisten; too much causes sogginess.
  • Step 2 — Preheat: Preheat the air fryer to 380°F (193°C) for a few minutes. A preheated basket starts the crisping immediately.
  • Step 3 — Cook in a single layer: Add the fries in a single layer with a little space between them. Overcrowding traps steam and is the number one cause of limp fries—cook in two batches if needed.
  • Step 4 — Shake and finish: Air fry for about 15 to 20 minutes total, shaking or tossing the basket every 5 minutes for even browning. The fries are done when deep golden and crisp; thicker cuts may need a couple of extra minutes.
  • Step 5 — Season again: Salt fries the moment they come out while the surface is hot, so the seasoning sticks. Serve right away.

Single Batch vs. Double Fry

Traditional restaurant fries are fried twice: once at a lower temperature to cook the interior, then again hot to crisp the outside. You can mimic this in the air fryer for an even crispier result. Cook the fries first at 330°F (165°C) for about 8 to 10 minutes to soften them through without much browning, let them rest for a few minutes, then crank the heat to 400°F (204°C) and finish for another 6 to 10 minutes until deeply golden. The brief rest between stages lets surface moisture escape, and the high final blast delivers that signature crackle. For a weeknight side, a single 380°F pass is perfectly good; save the double-fry method for when you want fries that taste like they came from your favorite diner.

Keeping Batches Hot and Crisp

If you are cooking multiple batches, hold finished fries on a wire rack set over a baking sheet in a 200°F (93°C) oven. A rack keeps air circulating underneath so the fries stay crisp instead of steaming on a plate. When all batches are done, you can return everything to the air fryer for one final two-minute blast to reheat and re-crisp.

Flavor Variations and Dips

  • Garlic parmesan: Toss hot fries with grated parmesan, minced garlic, and chopped parsley.
  • Cajun: Add Cajun or Creole seasoning to the oil before cooking.
  • Truffle: Finish with a drizzle of truffle oil and flaky salt.
  • Loaded: Top with cheese, bacon bits, and a dollop of sour cream.

Frequently Asked Questions

Do I have to soak the potatoes?

Soaking is not strictly required, but it noticeably improves crispiness by removing excess surface starch. If you are short on time, at least rinse the cut potatoes under cold water until it runs clear and dry them very well before seasoning.

Can I use frozen fries in the air fryer?

Absolutely. Frozen fries are already blanched and oiled, so skip the oil and soak. Cook them straight from frozen at 400°F (204°C) for about 12 to 16 minutes, shaking halfway through.

Why are my air fryer fries soggy?

The three usual causes are wet potatoes, too much oil, or an overcrowded basket. Dry the fries thoroughly, use only a light coat of oil, and cook in a single layer with space between the sticks.

What kind of oil is best?

Use a neutral oil with a high smoke point such as avocado, canola, or vegetable oil. These tolerate the high air fryer temperature without burning or imparting an off flavor.

How do I keep fries warm for serving?

Hold them on a wire rack in a 200°F (93°C) oven, then give all the fries a final short blast in the air fryer just before serving to bring back maximum crispness.
