What do you need?

Quantities for all ingredients are given in the recipe card below.

Sweet potatoes

Choose any variety of sweet potato. Ones that are elongated will cut better into traditional wedge shapes than the round-shaped ones.

Oil

I use light olive oil for this recipe, but you can substitute any cooking oil you normally use with your air fryer. Vegetable oil, corn oil, or avocado oil are all good options.

For a healthier version of this recipe, you can use an olive oil spray and just give the wedges a couple of spritzes of oil, or you can add more oil if you want to give the wedges a really crispy exterior.

Tip

When choosing an olive oil spray for your air fryer, look for the type that spritzes rather than an aerosol. The propellant in aerosol oil sprays can damage the non-stick coating of your air fryer.

Cornstarch (optional)

This helps to absorb any remaining surface moisture and will help the wedges to get really crispy. You can skip it if you don’t have any on hand.

Seasoning

The recipe below uses a blend of paprika, garlic powder, onion powder, and black pepper. You can use smoked paprika for a richer smoky flavor, or cayenne pepper for some heat if you like.

Alternatively, use a store-bought seasoning. You need around 3 teaspoons of seasoning in total.

Kosher salt

Use kosher salt or flaked salt season the wedges after cooking. Salt will draw the water out of the wedges

How to make sweet potato wedges in an air fryer

This recipe is very simple to make, but there are a few key steps to getting the sweet potatoes as crispy as possible:

  1. Don’t peel the sweet potatoes. Wash and scrub the sweet potatoes, but don’t peel them. The skin is be the crispiest part, so it is important to keep it.
  2. Cut the wedges thin. The thinner the wedges, the crisper they will become. Thick wedges are never going to get really crispy, so try to cut each sweet potato into 10-12 wedges. I halve them lengthwise, quarter them, then cut each quarter into three wedges.
  3. Pat wedges dry and dust with cornstarch. Pat the wedges dry with paper towels, or on a clean dish towel, then give them a light dusting of cornstarch, and leave them for around 15 minutes. Cornstarch helps to absorb any moisture remaining on the surface of the wedges, and will crisp up nicely as they cook. You can skip this step if you don’t have cornstarch at home, or are pushed for time, but it really will help with crispiness.

Note: There is no need to soak the sweet potato slices first. Air fryer recipes for white potatoes benefit from removing surface starch by soaking before seasoning. However, my testing of this recipe for sweet potato wedges didn’t find any benefit from soaking the wedges.

  1. Oil and season the wedges, but do not salt yet. Save the salt to season the wedges once they are cooked. Adding salt beofre cooking will draw water to the surface of the wedges during cooking making them soggy.
  2. Don’t overcrowd the basket. Place the sweet potato wedges in the air fryer basket in a single layer if possible, but don’t overcrowd them. Overcrowded sweet potato wedges will steam each other and never get crispy!
    If you want to cook more than will fit in a single layer you can stack them up a little in the air fryer basket [see photo below], but arrange them carefully so that the minimum amount of each wedge is touching the one below it. The wedges will only develop crisp outer surface on parts that are exposed to the hot air.
  3. Air fry hot, and flip often. Air fry the sweet potato wedges at 360°F/ 180°C. If you have stacked the wedges in the air fryer basket, then flip them halfway through the cooking time, and at least once more before the cooking time ends. Flip them so that all sides have been exposed to the hot air, helping them to get crispy.

Air fry sweet potato wedges for 15-20 minutes until golden brown. If they are stacked up, flip any that are touching other wedges halfway through the cooking time so that they cook evenly.

Serving

When the sweet potato wedges have finished cooking, season them with salt to serve.

Air fried sweet potato wedges are great served as a snack with your favorite dipping sauce, or as a quick and easy side dish to steak, grilled chicken, or fish.

Storage and reheating

Store any leftover sweet potato wedges in an airtight container in the refrigerator and use within three days.

You can reheat these wedges in the air fryer – place the wedges in the air fryer basket in a single layer, and air fry at 360°F/ 180°C until warmed through.

How to cook sweet potato wedges in an air fryer.

Ingredients

  • 1 lb / 450g sweet potatoes (approx. 2 medium)
  • 1 tablespoon light olive oil
  • 1 tablespoon cornstarch (optional)
  • 1 teaspoon paprika
  • 1 teaspoon onion powder
  • ½ teaspoon garlic powder
  • ¼ teaspoon fine ground black pepper
  • Kosher salt (to taste)

Instructions

  1. Wash and scrub the sweet potatoes (but don't peel them). Cut into thin wedges [Note 1].
  2. Pat the wedges dry.
  3. Optional: dust wedges with cornstarch, and leave them for 15 minutes to absorb the remaining surface moisture.
  4. Mix the oil and seasoning in a large bowl, add the wedges and toss to coat.
  5. Preheat the air fryer to 360°F/ 180°C.
  6. Place wedges in the air fryer basket [Note 2].
  7. Air fry the sweet potato wedges for 15-20 minutes at 360°F/ 180°C. Flip them halfway through cooking time if necessary [Note 3].
  8. Once the wedges are cooked to your liking, salt them to taste, and enjoy!

Notes

  1. I halve them lengthwise, quarter them, then cut each quarter into 2-3 wedges.
  2. If possible, place them in the air fryer basket in a single layer so that they are not touching. If you want to cook more than will fit in a single layer you can stack them up a little in the air fryer basket, but arrange them carefully so that the minimum amount of each wedge is touching the one below it.
  3. If you have stacked the wedges in the air fryer basket, then check them halfway through cooking and if there are any parts that are not crisping up properly then flip them so that all sides have been exposed to the hot air.
