Let's be clear-eyed about sweet potato fries: they are notoriously, almost comically hard to get crisp. The same sugars that make them delicious are the ones that want to burn and weep, and the high moisture inside fights the crust every step of the way. Restaurants cheat with a coating and a deep fryer at a temperature your home oven can't safely hold. So if you've made limp, sad sweet potato fries before, the fault was never yours — the vegetable is just stubborn.

The air fryer doesn't magically fix physics, and I won't tell you these come out exactly like a fryer's. But two whole-food moves get you genuinely close: a soak to pull out surface starch, and a light dusting of cornstarch to build a thin shell that shatters. Beyond that it's just oil, salt, and a little smoke from the paprika — a side made of food you can name, which is the whole point around here. The non-negotiable rule is space. Pile them deep and they steam each other into mush; give them a single roomy layer and they brown.

Cook them in the air fryer we lean on for vegetables and shake the basket often — movement is what gets every side browned.

Ingredients

×6
  • 2large sweet potatoes — peeled, cut into 1/4-inch sticks
  • 1 tbspcornstarch — or arrowroot
  • 1.5 tbspolive oil
  • 3/4 tspfine sea salt
  • 1/2 tspsmoked paprika
  • 1/4 tspgarlic powder

Method

  1. 01

    Cut the sweet potatoes into even quarter-inch sticks. Soak them in cold water for 15 minutes if you have time, then drain and dry them very well — pulling out surface starch is the secret to fries that crisp instead of steam.

  2. 02

    Toss the dried sticks with the cornstarch first, then the oil, paprika, garlic powder, and salt. The cornstarch is what gives you a crackly shell over a soft center.

  3. 03

    Air fry at 380°F for 18 minutes, shaking the basket two or three times, until the edges are browned and crisp. Work in batches so they're never piled deep — crowding is the only real enemy here.

  4. 04

    Tip onto a plate and salt again while hot. Sweet potato fries go soft quickly, so this is a serve-now situation.
