How to tell it’s done

Exterior is deep orange-brown and crisp; centre is fluffy when bitten. Bend a fry between fingers — it should hold its shape.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. Toss with 1 tbsp olive oil — sweet potatoes have very low natural fat.

2. 2

   Season

   Season with salt, smoked paprika, garlic powder, cumin, cayenne (optional).

3. 3

   Load

   Arrange 2 medium sweet potatoes (about 1 lb), cut into ¼-inch fries for best convection airflow.

4. 4

   Cook

   Set the air fryer to 380 °F (193 °C) and cook for 14 minutes total, shaking once at 7 minutes.

5. 5

   Check & rest

   Check the visual doneness cue and serve immediately for best texture.

6. 6

   Store

   Best eaten fresh; reheat at 400 °F for 3 minutes if storing.

Watch out for

• !Sweet potato fries crisp slower than regular potato fries because of the higher sugar content. Resist the urge to crank the temperature above 380 °F — they burn outside before crisping.
• !Soak cut fries in cold water for 30 minutes before cooking to draw out starch; pat completely dry. This is the single biggest crisp-factor.
