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 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. Be careful not to burn them!
  • Speaking of cooking, sweet potato fries have natural sugars in them. These sugars can brown/blacken the fries but it’s normal. Also, these sugars can make a bit more of a mess than usual when you’re cleaning your air fryer.
  • 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!

We use this air fryer for our recipes and it has been great.

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!

Use one large sweet potato.

Peel the sweet potato if you don’t like eating it with the peel on.

Otherwise, just wash the sweet potato and then pat it dry well. This is important since you don’t want extra moisture to get into the air fryer.

Instead of a large sweet potato, you can also use two smaller ones.

Cut the fries.

Cut the sweet potato into half if it is big (so the fries aren’t too long), then cut it into 1/2 inch fries for thick fries or 1/4 inch fries for thin fries.

In the photo above, we made thick cut sweet potato fries.

Keep in mind that thin fries will end up crispier than thick fries and need a little bit less time in the air fryer.

Add the spices.

Place the sweet potato fries into a mixing bowl. Then also add oil, salt, pepper, garlic powder, and paprika to the bowl. 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 and 16-20 minutes for 1/2 inch fries – shake the tray every 5 minutes for even cooking.

Since every air fryer is different, your cooking time might vary slightly!

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 a few 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 or just microwave them – but, again, the microwave will definitely not make them crispy!

What to Serve Air Fryer Sweet Potato Fries With

Air fried sweet potato fries are great as a snack on their own but they also work really well as a side dish.

They can be paired with other finger food like chicken nuggets, chicken fries, etc.

They can also work as a side dish to barbecue dishes, a big salad, or a wrap.

Air Fryer Sweet Potato Fries

Yield: 4
Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes

Air fryer sweet potato fries are super delicious. Made from sweet potatoes cut to your liking, these fries just need a little oil and some simple spices to be perfect - and serve great with a creamy dipping sauce!

Ingredients

  • 1 large sweet potato
  • 2 teaspoons avocado oil (see notes)
  • 1/2 teaspoon salt (more to taste)
  • 1/4 teaspoon pepper
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon paprika

Instructions

  1. First, peel the sweet potato if desired (we don't usually do that though). If you decide to leave the skin on, wash the sweet potato well, then dry it.
  2. Cut the sweet potato in half, then cut it into 1/2 inch fries for thick fries or 1/4 inch fries for thin fries (thin fries will likely end up crispier than thick fries).
  3. Add the sweet potato fries to a mixing bowl. Also add oil, salt, pepper, garlic powder, and paprika to the bowl. Toss until the fries are evenly coated.
  4. Preheat the air fryer to 385 degrees Fahrenheit.
  5. Once heated, evenly spread the sweet potato fries onto the air fryer tray.
  6. Cook the fries for 13-16 minutes for 1/4 inch fries and 16-20 minutes for 1/2 inch fries - shake the tray every 5 minutes for even cooking. Since every air fryer is different, your cooking time might vary slightly!

Notes

  • We don't usually recommend using olive oil in the air fryer because it has a low smoke point. Better oil options are avocado oil (that's what we use), sesame oil, or even canola oil.
  • Try not to overcrowd the food in the air fryer. Everything needs space to cook so that it can cook evenly and get crispy. We have a 6-quart capacity air fryer so if you have a smaller one, you may have to cook these sweet potato fries in two batches.
