The exact cook time can vary. Read below for our tips!
Air fryer sweet potatoes are a great snack or simple side dish! Crispy on the outside and soft on the inside, these fries are quite easy to make and you can season them however you like.
We like sweet potato fries out of the air fryer with a creamy dipping sauce like mayonnaise or aioli, but there are lots of options!
Ingredients
Here are the ingredients needed to make these fries in the air fryer:
- 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
- You can cut the sweet potato fries thick or 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.
- Don’t overcrowd your air fryer. If you have a very small one, you may have to cook the fries in two batches.
- Shake the air fryer basket regularly during cooking so that the sweet potato fries can cook and crisp evenly.
- If you only have frozen sweet potato fries, you can air fry those, too – the cooking time may just be slightly different.

Step by Step Instructions
First, peel the sweet potato if you don’t like eating it with the peel on.
Otherwise, rinse 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.
Next, cut the sweet potatoes lengthwise into large slices between ¼ and ½ inch thick.
Then 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 the oil, salt, pepper, garlic powder, and paprika.
We also added a bit of 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.
Once preheated, evenly place the sweet potato fries in the air fryer basket. If they don’t all fit, it’s better to cook them in two batches – otherwise, they might not cook evenly nor get crispy.
Cook the fries at 385 degrees Fahrenheit for about 13-16 minutes for 1/4 inch fries, or until fully cooked and crispy. Shake the air fryer basket every 5 minutes for even cooking.
If your fries are thicker, they may take slightly longer. 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. Enjoy!
Storage Tips
Sweet potato fries in the air fryer are best served fresh while they are warm and crispy.
If you have any leftovers, store them in a sealed container in the fridge for up to 3-4 days. We recommend eating them sooner rather than later since they tend to get mushy over time.
You can reheat them in the air fryer to get some of the crispiness back or just microwave them – but, again, the microwave will not make them crispy!

Delicious. I’m new to eating sweet potatoes and these were delicious. Make sure you cut them thin or else they’re a bit squishy.
