For the perfect snack or side dish, you’ve got to make air fryer sweet potato fries. Crispy on the outside and soft and sweet on the inside, these fries are really tasty.
We like sweet potato fries out of the air fryer with a creamy dipping sauce like mayonnaise or a nice garlic aioli!

Ingredients

Here are the ingredients needed to make these fries in the air fryer. It doesn’t take too much to create delicious fries in no time at all!
- Sweet potatoes – Use either 2 medium sweet potatoes or one large one, about 1 pound total.
- Avocado oil – Alternatively use canola oil, sunflower oil or vegetable oil.
- Salt – To add flavor; add more or less to taste.
- Garlic powder – To add extra flavor.
- Paprika – For flavor; feel free to skip if you don’t like paprika.
- Ground Pepper – For flavor; a little goes a long way.
- Corn starch – Optional, but can help with crispiness.
Recipe Tips & Substitutions
Before you air fry sweet potato fries, be sure to check out our recipe tips and/or modifications so that you achieve the best results!
- You can cut the sweet potato fries thick or cut them thin. Just remember that thicker fries will likely not be as crispy and will take longer in the air fryer whereas thinner cut fries will take less time and will end up getting crispier.
- Cut the sweet potato fries evenly so that they are done cooking at the same time.
- Shake the air fryer basket regularly during cooking so that the sweet potato fries can cook and crisp evenly.
- We use avocado oil in the air fryer because it has a high smoke point and do not recommend using virgin olive oil due to its low smoke point.
- Make sure not to overcrowd your air fryer. If you have a very small one, you might have to cook the fries in two batches.
- If you only have frozen sweet potato fries, you can air fry those, too – it’s just a slightly different recipe that we have!
Step by Step Instructions
If you are wondering how to make sweet potato fries in the air fryer and want some visual step-by-step instructions, you can find the recipe process photos below.
This way, if you have any questions about how we make ours, you have visuals to refer to!
Peel the sweet potato if you don’t like eating it with the peel on.
Otherwise, just wash the sweet potatoes and then pat them dry well. This is important since you don’t want extra moisture to get into the air fryer.
Instead of using two medium-sized sweet potatoes, you can also use one large sweet potato.

Cut the sweet potatoes lengthwise into large slices between ¼ and ½ inch thick.

Next, lay the slices down flat and cut them into fries about a ¼ to ½ inch thick. You can cut your fries thicker, but this will affect cooking time.
In the photo above, we made thinner cut sweet potato fries.
Keep in mind that thin fries will likely end up crispier than thick fries and need a little bit less time in the air fryer.

Place the sweet potato fries into a mixing bowl. Then also add oil, salt, pepper, garlic powder, and paprika to the bowl.
We also added corn starch, but this is optional (it can help with crispiness).

Toss well until the fries are evenly coated.
Of course you can always modify the spices you use to adjust the flavor according to your personal preferences.

Preheat the air fryer to 385 degrees Fahrenheit.
When it is hot, evenly spread the sweet potato fries onto the tray. If they don’t all fit, it’s better to fry them in two batches – otherwise they might not cook evenly nor get crispy.

Cook the fries for 13-16 minutes for 1/4 inch fries. Shake the tray every 5 minutes for even cooking. If you cut thicker fries, they will may take slightly longer to air fry.
Keep an eye on the sweet potato fries towards the end since they can get dark quite quickly.
Since every air fryer is different, your cooking time might vary slightly!

When they are done to your liking, remove the sweet potato fries from the air fryer and serve them with your favorite dipping sauce.
Storage Tips
Sweet potato fries in the air fryer are best served fresh while they are warm and crispy.
If you have any leftovers, you can store them in a sealed container and put them in the fridge. They will last for about 3-4 days but they are best eaten as soon as possible.
This is because sweet potato fries generally still have a bit of moisture content in them. Left in a sealed container, they inevitably will get a little mushy but they still taste great.
You can reheat them in the air fryer to get some of the crispiness back or just microwave them – but, again, the microwave will definitely not make them crispy!
