Homemade french fries in the air fryer come out crisp on the outside and fluffy inside, with far less oil than deep frying. You will cut the potatoes, soak off excess starch, dry them thoroughly, and cook them in two stages. The whole process takes about 30 minutes of active and cooking time.

What You Need Before You Start

Russet potatoes give the best texture because their high starch content produces a fluffy interior. Yukon Gold works too, though the fries will be a little creamier and less crisp. You also need a small amount of neutral oil and a way to dry the cut potatoes well.

  • 2 large russet potatoes (about 1 pound)
  • 1 tablespoon neutral oil such as avocado, canola, or vegetable oil
  • 1/2 teaspoon fine salt, plus more to taste
  • A sharp knife or a fry cutter
  • A large bowl of cold water
  • Clean kitchen towels or paper towels

How to Cut and Prep the Potatoes

Peel the potatoes and cut them into sticks about 1/4 inch thick. Uniform sizes matter more than the exact width, because thin pieces burn while thick ones stay soft. Work in batches and keep the cut fries in cold water as you go so they do not discolor.

Soak the fries in cold water for at least 30 minutes, and up to 2 hours if you have time. Soaking pulls out surface starch, which is what causes sticking and uneven browning. Change the water once if it turns cloudy.

Dry the Fries Completely

Drain the fries and pat them dry with towels until no moisture remains on the surface. Any water left on the potatoes will steam them in the basket instead of crisping them. Spread them on a towel for 10 minutes if you are unsure.

How to Cook Homemade French Fries Air Fryer Style

Toss the dry fries with the oil and salt in a bowl until every piece has a thin, even coat. Arrange them in a single layer in the basket, leaving gaps between pieces. Cook in batches if needed, because crowding blocks airflow and produces soggy fries.

  1. Preheat the air fryer to 380°F for 3 minutes.
  2. Cook the fries at 380°F for 12 minutes, shaking the basket every 4 minutes.
  3. Increase the heat to 400°F and cook for another 6 to 10 minutes, shaking every 3 minutes, until golden and crisp.
  4. Remove the fries and season with a little more salt while they are hot.

Air fryer models vary in power, so start checking at the lower end of the time range. Fries are done when the edges are deep golden and a fry bends slightly without breaking.

Cooking Time Reference

Fry Thickness First Stage (380°F) Second Stage (400°F)
1/4 inch sticks 12 minutes 6 to 10 minutes
3/8 inch wedges 15 minutes 8 to 12 minutes
1/8 inch shoestrings 8 minutes 4 to 6 minutes

Common Mistakes to Avoid

  • Skipping the soak. Surface starch causes fries to stick together and brown unevenly.
  • Leaving the fries wet. Moisture steams the potatoes, so dry them thoroughly before oiling.
  • Overcrowding the basket. Cook in batches so hot air can circulate around each piece.
  • Using too much oil. One tablespoon for two potatoes is enough, and extra oil makes them greasy.
  • Salting before cooking. Salt can draw out moisture, so season right after the fries come out.

A mandoline or fry cutter makes uniform sticks much faster than cutting by hand. A digital thermometer helps you confirm your air fryer is holding the correct temperature. For frying batches, a large salad spinner works well for drying soaked potatoes quickly. View on Amazon View on Amazon

FAQ

Do I need to parboil potatoes before air frying?

No, parboiling is not required. Soaking in cold water and drying well gives good results. Parboiling can make fries even fluffier, but it adds a step and extra mess.

Can I make homemade french fries in the air fryer without oil?

You can use a very light spray or skip oil entirely, but the fries will be drier and less golden. A small amount of oil helps them brown evenly and taste richer.

Why are my air fryer fries soggy?

Soggy fries usually mean the potatoes were not dried enough or the basket was overcrowded. Dry them thoroughly and cook in a single layer, shaking halfway through. For reheating leftovers, see Reheating Fries in Air Fryer: A Step-by-Step Guide for Crispy Results.

Conclusion

Homemade french fries in the air fryer are simple once you master the soak, dry, and two-stage cook. Start with russet potatoes and cut them evenly for the most consistent results.
