👩‍🍳 How to Make Air Fryer Sweet Potato Fries

Step 1: Preheat the Air Fryer

Preheat your air fryer to 375°F (190°C). Preheating helps ensure even cooking and crispier results.

Step 2: Cut the Sweet Potatoes

Slice the sweet potatoes into ¼-inch-wide strips. Try to keep them uniform so they cook evenly.

Step 3: Season the Fries

Place the cut fries in a large bowl. Add the oil and toss thoroughly to coat.

Sprinkle in onion powder, paprika, salt, and pepper. Toss again until evenly coated.

Step 4: Air Fry

Arrange the fries in a single layer in the air fryer basket. Do not overcrowd. Cook in batches if necessary.

Air fry for 15–20 minutes, shaking the basket halfway through cooking.

Step 5: Serve

Remove once golden and crispy. Sprinkle with extra salt if desired and serve immediately.

The Secret to Crispy Air Fryer Sweet Potato Fries

Sweet potatoes contain more natural sugars and moisture than regular potatoes, which makes them more prone to softness rather than crispiness. Here’s how to guarantee crispy Air Fryer Sweet Potato Fries:

1. Cut Evenly

Uniform fries cook evenly and crisp better.

2. Soak in Cold Water (Optional but Recommended)

Soak cut fries in cold water for 30 minutes. This removes excess starch and helps improve crispiness.

After soaking, dry thoroughly with paper towels.

3. Use Just Enough Oil

Too much oil makes fries soggy. A light coating is perfect.

4. Don’t Overcrowd

Air circulation is key. Overlapping fries steam instead of crisp.

5. Shake Halfway Through

This ensures even browning on all sides.

The Science Behind Crispy Air Fryer Sweet Potato Fries

Air fryers circulate hot air rapidly around food. This creates a Maillard reaction — the browning process responsible for crispiness and flavor.

Because sweet potatoes contain natural sugars, they caramelize beautifully when exposed to high heat.

Proper airflow + dry surface + moderate oil = perfect crisp.
