Instructions

1
Cut the russet potato into fry shapes, about 1/4 to 1/2 inch thick.
2
Bring a pot of water to a boil and add the baking soda.
3
Carefully add the cut potatoes to the boiling water and boil for 10 minutes. The potatoes will look slightly broken down on the exterior.
4
Drain the potatoes and toss them in a bowl with olive oil to coat.
5
Arrange the oiled fries in a single layer on a wire rack and place in the refrigerator to dry for at least 30 minutes.
6
Place the chilled fries into the air fryer basket.
7
Perform the first fry at 330°F (165°C) for 15 minutes.
8
Remove the fries from the air fryer and let them rest and cool for about 15 minutes.
9
Return the fries to the air fryer for the second fry at 380°F (193°C) for 7 minutes, or until golden brown and crispy.
10
Remove the finished fries from the air fryer, season immediately with salt, and toss to coat.

Tips & Notes

Pro tips

Soak cut potatoes in ice water for 30 minutes before boiling to remove excess starch and ensure more even cooking.
Do not skip the chilling step between fries—cold potatoes fry crispier because moisture won't escape as steam during the second fry.
Cut fries to uniform thickness (about ¼-inch) so they cook evenly and reach doneness at the same time.
Pat fries completely dry after the first fry before chilling and before the second fry to prevent oil splattering and maximize crispness.

Substitutions

Russet potato → Yukon Gold (yields fluffier interior, slightly less crispy exterior)
Olive oil → Vegetable or peanut oil (neutral flavor, higher smoke point for consistent frying)

Storage & make-ahead

Store cooled fries in an airtight container at room temperature for up to 1 day; reheat in a 350°F oven for 5-7 minutes to restore crispness.

Equipment

deep-fry thermometer · heavy-bottomed pot or Dutch oven · slotted spoon or spider strainer

Common Questions

Why do you boil potatoes before frying french fries?

Boiling breaks down the potato's surface starch and gelatinizes it, allowing the fries to absorb less oil during frying and become crispier on the outside while staying fluffy inside.

What does baking soda do in french fries?

Baking soda raises the pH of the boiling water, helping soften the potato surface faster and create a more alkaline exterior that browns and crisps more effectively during frying.

How long should you chill the fries before the second fry?

Chill the blanched and fried fries for at least 15-30 minutes in the freezer to ensure a crispy exterior develops during the final fry without overcooking the interior.
