Ingredients
  

  • 2 medium sweet potatoes (about 1.5–2 lbs total)
  • 1–1.5 tablespoons olive oil or avocado oil
  • 1 teaspoon cornstarch (optional, for extra crispness)
  • 1 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika
  • 1/4 teaspoon ground cumin (optional)
  • 1/2 teaspoon fine sea salt, plus more to taste
  • Freshly ground black pepper
  • Zest of 1 lime
  • 1/2 teaspoon chilli powder or mild chilli flakes (adjust to taste)
  • Pinch of cayenne (optional, for extra heat)
  • Lime wedges, for serving
  • Fresh cilantro or parsley, chopped (optional garnish)

Method
 

  1. Prep the potatoes: Scrub sweet potatoes well. You can peel them or leave the skin on for extra texture. Slice into even wedges about 3/4 inch thick so they cook uniformly.
  2. Soak (optional but helpful): For maximum crispness, soak the wedges in cold water for 15–20 minutes to remove some surface starch. Drain and pat very dry with a clean towel.
  3. Preheat the air fryer: Set to 390–400°F (200°C) for 3–5 minutes. A hot basket helps the edges crisp up fast.
  4. Season the wedges: In a large bowl, toss wedges with oil. Sprinkle over cornstarch, garlic powder, smoked paprika, cumin (if using), 1/2 teaspoon salt, and black pepper. Toss until evenly coated and no dry patches remain.
  5. Arrange in the basket: Place wedges in a single layer with a little space between each piece. Work in batches if needed. Don’t overcrowd—that’s key for crispness.
  6. Air fry: Cook for 14–18 minutes, shaking the basket or flipping wedges halfway. They’re done when edges are caramelized and centers are tender.
  7. Make the lime chilli salt: In a small bowl, mix lime zest, chilli powder or flakes, and a pinch of cayenne with a little fine sea salt. Taste and adjust heat and salt.
  8. Finish and serve: Transfer hot wedges to a bowl. Sprinkle with the lime chilli salt while they’re still steaming, and toss gently. Serve with lime wedges and fresh herbs if you like.
