This Air Fryer Sweet Potato Fries Recipe gives you golden, crispy sweet potato fries with minimal oil, bold seasoning, and fluffy centers. Whether you’re preparing a healthy side dish, snack, or meal prep staple, this quick recipe ensures consistent results every time.

Ingredients List

The key to crispy air fryer sweet potato fries is balance—natural sweetness, seasoning depth, and light oil coating.

Main Ingredients:

2 large sweet potatoes (about 1½ pounds)
1–2 tbsp olive oil or avocado oil
1 tbsp cornstarch (crucial for crispiness)
½ tsp salt
½ tsp black pepper
½ tsp smoked paprika
¼ tsp garlic powder

Optional Seasoning Variations:

Cinnamon + pinch of cayenne (sweet heat)
Cajun seasoning for bold flavor
Parmesan + Italian herbs
Chili powder + lime zest

Timing

Prep Time: 10 minutes
Cook Time: 10–14 minutes
Total Time: 20–25 minutes

Compared to oven baking (typically 35–40 minutes), air frying cuts cooking time by nearly 40%.

Step-by-Step Instructions

Step 1: Cut Evenly

Peel (optional) and slice sweet potatoes into evenly sized fries, about ¼-inch thick.

Uniform cuts ensure even cooking.

Step 2: Soak for Extra Crispiness (Optional but Recommended)

Soak fries in cold water for 30 minutes to remove excess starch.

Pat completely dry with paper towels.

Pro Tip: Removing surface starch helps achieve a crispier exterior.

Step 3: Coat Lightly

In a large bowl, toss fries with oil until lightly coated.

Sprinkle cornstarch and seasonings evenly. Toss again to coat.

Cornstarch creates a thin crisp layer during air frying.

Step 4: Preheat Air Fryer

Preheat air fryer to 380°F (193°C) for 3–5 minutes.

Preheating promotes better browning.

Step 5: Air Fry in Batches

Arrange fries in a single layer without overcrowding.

Cook for 10–14 minutes, shaking basket halfway through.

Fries are done when golden brown and slightly crisp at edges.

Step 6: Final Crisp Boost (Optional)

For extra crunch, increase temperature to 400°F (204°C) for last 2 minutes.

Sprinkle additional salt immediately after cooking.
