Air fryer sweet potato fries are the perfect balance of sweet and savoury with an irresistibly crispy finish—without the heavy oil of deep frying. They’re healthier, quick to make, and a great side dish for burgers, sandwiches, or even as a snack with your favourite dip.

Ingredients

  • 2 medium sweet potatoes (about 500 g), peeled and cut into thin fries
  • 1–2 tablespoons olive oil
  • ½ teaspoon smoked paprika (or regular paprika)
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 teaspoon cornstarch (optional, for extra crispiness)

How to Make Air Fryer Sweet Potato Fries

  1. Prepare the potatoes: Peel and cut sweet potatoes into thin, even fries (about ¼ inch thick).
  2. Soak (optional): For maximum crispiness, soak the cut fries in cold water for 30 minutes, then pat completely dry.
  3. Season: Place fries in a bowl, drizzle with olive oil, sprinkle with cornstarch (if using), and toss with paprika, garlic powder, onion powder, salt, and pepper.
  4. Preheat air fryer: Heat the air fryer to 200°C (400°F) for 3 minutes.
  5. Cook: Arrange fries in a single layer in the basket (work in batches if needed). Cook for 12–15 minutes, shaking halfway through, until golden and crisp.
  6. Serve: Sprinkle with a little extra salt and serve hot with dips like garlic mayo, ketchup, or sriracha aioli.

You Must Know

  • Even cuts = even cooking: Thin, uniform fries crisp up better.
  • Don’t overcrowd: Too many fries in the basket will steam instead of crisp.
  • Cornstarch trick: A light dusting helps mimic restaurant-style fries.

Topping Variations

  • Spicy: Add cayenne or chilli powder.
  • Sweet & Savoury: Toss with cinnamon and a pinch of brown sugar.
  • Herby: Mix with dried rosemary or thyme before air frying.
  • Cheesy: Sprinkle with grated parmesan after cooking.

Make It a Meal

Pair your sweet potato fries with:

  • Burgers (beef, chicken, or veggie)
  • Grilled sandwiches like air fryer grilled cheese
  • BBQ chicken or ribs
  • Fresh salad bowls

Pro Tips

  • Preheat your air fryer every time for crispier results.
  • Shake the basket halfway through for even browning.
  • If cooking multiple batches, keep finished fries warm in a 90°C oven until serving.

Recipe FAQs

Q: Can I make these without oil?
Yes, but they’ll be less crispy. Use at least a light spray of oil for the best texture.

Q: How do I reheat leftovers?
Reheat in the air fryer at 180°C (360°F) for 3–4 minutes until hot and crispy again.

Q: Can I leave the skin on?
Absolutely! Just scrub the sweet potatoes well and cut into fries—skins add extra fibre and texture.

  3. Toss fries with oil, salt, garlic powder, black pepper and paprika.

  1. Peel each sweet potato and slice into even 1/4-inch thick planks, then into 1/4-inch thick fries.

  3. Toss sweet potatoes with 1 teaspoon of the oil in a clean, dry bowl, then transfer all to the air fryer basket.
  4. Place basket in air fryer (no need to preheat) and air fry 350F degrees 8 minutes, then shake and cook, 5 more minutes.
