These air fryer sweet potato wedges are a quick and easy side dish you’ll come back to over and over again. They’re insanely delicious – perfectly crispy on the outside, tender on the inside, and bursting with flavor. You would never know they are so easy to throw together.
Sweet potato wedges + air fryer = 😍
I love sweet potato wedges. They are packed full of nutrients, and despite the sweet taste, have fewer calories than regular potatoes.
My favourite way to make them is (you guessed it!) in the air fryer! They’re easy to prep, and cook surprisingly quickly (remember to keep an eye on them!) and come out with beautifully crispy edges. Plus, I love that I can scoff them guilt-free knowing they’re not swimming in a vat of oil!

What do you need?
Sweet potatoes
Choose any variety of sweet potato. Elongated sweet potatoes will cut better into traditional wedge shapes than 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. You can use an oil spray for a lighter version.
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.
Cornflour 🇬🇧/ 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 hot paprika for some heat.
Alternatively, use a store-bought seasoning. You need around 2-3 teaspoons of seasoning in total.
Salt
Season the wedges with salt after cooking. Salt will draw the water out of the sweet potato during cooking making them soggy if you add it before cooking. Note: Don’t add extra salt if you are using a seasoning mix that has salt in it already!
Let’s cook these sweet potato wedges in the air fryer!
1
Cut the wedges.
Wash and scrub the sweet potatoes, but don’t peel them. The skin is the crispiest part, so it is important to keep it. Cut the wedges thin – the thinner the wedges, the crisper they will become.
2
Season the wedges.
Pat the wedges dry. Then give them a light dusting of cornflour/ cornstarch, and leave them for around 5 minutes to absorb any moisture remaining on the surface of the wedges. This is optional but will help them to get crispier.
Place the wedges in a large bowl, drizzle with oil and seasoning (but not the salt yet), and toss to coat.
3
Preheat.
Preheat the air fryer to 200°C/ 400°F. Preheating is important for this recipe because the air frying time is relatively short, and so you want it to be up to temperature when you put the wedges in.
If your air fryer doesn’t have a preheat mode, just set it to air fry for 3-4 minutes.
4
Pop the wedges in the air fryer.
Put the sweet potato wedges in the air fryer basket in a single layer if possible or stack the wedges to maximise the outer surface that will be exposed to the hot air.
5
Air fry!
Air fry the sweet potato wedges at 200°C/ 400°F. 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.
Tips for really crispy wedges
- Pat the wedges dry after cutting, but there is no need to soak them. I’ve tested this several times, and soaking made no difference to crispiness.
- To get really crispy sweet potato wedges, give them a light dusting of cornstarch, and leave them for a few 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.
- Don’t add salt till after they are cooked. Adding salt before cooking will draw water to the surface of the wedges during cooking making them soggy.
- Don’t overcrowd! If there are too many wedges in the air fryer they will steam each other and never get crispy.
Variations and serving ideas
- Toss wedges in Cajun seasoning before baking for a kick of spice. Serve with a cooling ranch or blue cheese dip.
- Top the cooked wedges with Parmesan cheese, and fresh herbs.
- Season with chili powder, cumin, garlic powder before cooking for Tex-Mex style wedges. Serve with avocado dip or sour cream.
- Drizzle with maple syrup and add a dash of cinnamon for a sweet touch.
- Spice it up with curry powder, coriander and ginger. Serve with raita.
- Pile with chili or pulled pork, sour cream, salsa, or other toppings for loaded sweet potato nachos.
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 sweet potato wedges in the air fryer – place them in the air fryer basket in a single layer, and air fry at 360°F/ 180°C until warmed through.
Air Fryer Sweet Potato Wedges
Ingredients
- 500 g / 1.1 lb sweet potatoes (approx. 3 medium)
- 2 tablespoon light olive oil
- 1 tablespoon cornflour/ corn starch (optional)
- 1 teaspoon paprika (sweet, smoked, or hot)
- ½ teaspoon onion powder
- ½ teaspoon garlic powder
- ¼ teaspoon fine ground black pepper
- salt (to taste)
Directions
- Wash and scrub the sweet potatoes (but don’t peel them). Cut into thin wedges [Note 1].
- Pat the wedges dry.
- Optional: dust wedges with cornstarch, and leave them for 5 minutes to absorb the remaining surface moisture.
- Place the wedges in a large bowl, drizzle with oil, add the seasonings and toss to coat.
- Preheat the air fryer to 200°C/ 400°F.
- Place wedges in the air fryer basket in a single layer (if possible [Note 2]).
- Air fry the sweet potato wedges for 15-20 minutes at 200°C/ 400°F. Flip them halfway through cooking time to ensure they cook evenly.
- Once the wedges are cooked to your liking, salt them to taste, and enjoy!
Notes
- I halve them lengthwise, quarter them, then cut each quarter into 2-3 wedges.
- 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.
- 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.
