Shopping List

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

Zest of 1 lime
1/2 teaspoon chilli powder or mild chilli flakes (adjust to taste)

Fresh cilantro or parsley, chopped (optional garnish)

Instructions

Cooking process: Overhead shot of an air fryer basket arranged in a single layer with evenly spaced

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.
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.
Preheat the air fryer: Set to 390–400°F (200°C) for 3–5 minutes. A hot basket helps the edges crisp up fast.
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.
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.
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.
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.
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.

Keeping It Fresh

Storage: Cool completely, then store in an airtight container in the fridge for up to 3 days.
Reheating: Air fry at 375°F (190°C) for 4–6 minutes to revive the crisp edges. Avoid microwaving if you can—it softens them.
Make-ahead tips: You can cut the wedges a few hours ahead and keep them in cold water in the fridge. Dry thoroughly before cooking.
Freeze: Not ideal.
The texture gets a bit mealy after thawing. If you must, par-cook for 8 minutes, cool, freeze on a tray, then finish from frozen at 390°F, adding a few extra minutes.

Why This is Good for You

Fiber and complex carbs: Sweet potatoes provide sustained energy and help keep you full.
Vitamin A powerhouse: They’re rich in beta-carotene, which supports eye health and immunity.
Lower oil, big payoff: Air frying uses far less oil than deep frying, reducing overall calories and saturated fat.
Zesty finish, less salt: Lime zest and chilli add big flavor, so you can keep the sodium modest without sacrificing taste.

Pitfalls to Watch Out For

Overcrowding the basket: Too many wedges steam instead of crisp. Cook in batches for best results.
Skipping the dry-off: If you soak the wedges, pat them very dry.
Extra moisture fights against browning.
Uneven cuts: Thin pieces burn before thicker ones are tender. Aim for consistent thickness.
Under-seasoning: Sweet potatoes can handle bold flavors. Taste and adjust lime chilli salt at the end.
Cold start: Preheating matters.
A hot basket helps form that caramelized exterior.

Recipe Variations

Garlic-Parmesan Twist: Skip the chilli. Toss hot wedges with 2 tablespoons finely grated Parmesan, extra garlic powder, and a pinch of parsley.
Lemon-Herb: Use lemon zest instead of lime. Finish with chopped dill or thyme and flaky salt.
Maple-Chipotle: Add 1 teaspoon maple syrup and 1/2 teaspoon chipotle powder to the oil mixture.
Finish with lime zest and a little flaky salt.
Coconut-Lime: Use coconut oil instead of olive oil, then finish with lime zest and toasted shredded coconut.
Super-Spiced: Add garam masala or curry powder to the seasoning, then finish with lime and cilantro.
Extra-Crisp: Use the cornstarch plus a second short fry: 390°F for 12 minutes, rest 3 minutes, then another 3–4 minutes until deeply browned.

FAQ

Do I have to peel the sweet potatoes?

No. The skin gets pleasantly chewy and adds fiber and nutrients. Just scrub well.

Peel if you prefer a cleaner look or softer texture.

Can I use regular potatoes instead?

Yes. Russets or Yukon Golds work great. Adjust timing by a couple of minutes and season to taste.

How do I make them less spicy?

Use mild chilli powder, reduce the amount, or skip the cayenne.

You’ll still get plenty of flavor from the lime zest and smoked paprika.

What dipping sauces go well with these?

Try garlic yogurt, chipotle mayo, avocado-lime crema, or a quick tahini-lemon sauce. Ketchup and aioli are classics too.

My wedges aren’t crisp. What went wrong?

Likely overcrowding or too much moisture.

Dry the wedges well, preheat the air fryer, and cook in batches. Cornstarch also helps.

Can I bake them instead of air frying?

Yes. Roast at 425°F (220°C) on a preheated sheet pan for 25–35 minutes, flipping once.

Use convection if you have it.

Is cornstarch necessary?

No, but it adds a thin, crisp coating. If you skip it, make sure the wedges are very dry and don’t skimp on preheating.

How do I scale the recipe for a crowd?

Double or triple the ingredients and cook in waves. Keep finished wedges warm in a low oven (200°F/95°C) on a wire rack so they stay crisp.
