Using your Plum Chef Air Fryer Oven, this recipe delivers golden-brown, crispy sweet potato fries with minimal oil — a nutritious alternative to traditional fries. Paired with a smoky, slightly spicy chipotle mayo, this dish is sure to become a favorite.

Sweet potatoes are rich in vitamins and fiber, and when prepared in the air fryer, they become wonderfully crispy without deep-frying. The secret to perfect air-fried sweet potato fries lies in cutting them evenly and arranging them in a single layer for optimal air circulation. With the Plum Chef oven’s FRENCH FRIES function, you get consistent, restaurant-quality results every time.

Whether you're preparing a quick snack, a side dish for dinner, or an appetizer for guests, this recipe is both simple and impressive. Let’s get started!

INGREDIENTS:

For the Chipotle Mayonnaise:

• ½ cup (125 ml) mayonnaise

• ¼ teaspoon (1 ml) fresh lemon juice

• 1 chipotle chile in adobo, finely chopped
  

For the Sweet Potato Fries:

• Olive oil, for spraying

2. Prepare the Sweet Potato Fries: Place the cut sweet potatoes into the Air Fryer Basket. Spray liberally with olive oil, then sprinkle with kosher salt. Toss to coat evenly.

3. Arrange the sweet potato pieces in a single layer in the basket to ensure even cooking and crispiness.

4. Insert the Air Fryer Basket into rack Position 2 of your Plum Chef oven. Select the FRENCH FRIES function and set the temperature to 230°C for 21 minutes. Cook until the fries are golden brown and crispy.

Chef’s Tip: For extra crispiness, make sure the sweet potatoes are thoroughly dried before spraying with oil. Avoid overcrowding the basket — cook in batches if necessary.
