Why Make Healthy Sweet Potato Fries in Air Fryer?

  • Crispy in 14 minutes: Unlike baked versions, there’s no need to pre-soak, use cornstarch, bake for 40+ minutes rotating pans and carefully flipping each fry, or crack the oven door for 15+ minutes to achieve these fuss-free SUPER CRISPY results.
  • Use fresh or frozen: Plus, how to freeze sweet potato fries to air fry later!
  • Super versatile: There are tons of ways to season and serve them!
  • Flavor: These healthy air fryer sweet potato fries are sweet (thanks to the natural sugars caramelizing), salty, savory, and utterly delicious!
  • Diet friendly: Gluten free, vegetarian, vegan, and even possibly oil free (which doubles up as WFPB)!
  • Nutritious: Sweet potato fries contain impressive levels of beta-carotene (made into vitamin A), vitamin C, potassium, copper, and other vitamins and minerals. More so, they’re packed with fiber and antioxidants and are lower GI than white potatoes.
  • Child approved: Perfect for encouraging them to eat more vegetables. I mean, who doesn’t like fries?

Ingredients for Air Fryer Sweet Potato Fries

  • Sweet potatoes: You’ll need medium sweet potatoes around the same size. Make sure they aren’t too long, so they easily fit in your air fryer basket.
  • Oil: I use extra-virgin olive oil, though avocado oil and other neutral cooking oils will also work.
  • Seasonings: I use a basic (but super tasty) seasoning made with garlic powder, paprika (regular or smoked), and sea salt and pepper.

Garlic powder works best vs. fresh, as fresh garlic is more apt to burn, same goes for air fryer asparagus and cauliflower, too!

Keep reading below (after the recipe how-to) for more information on any add-ins and recipe variations!

How to Cut Homemade Sweet Potato Fries

  1. First, make sure to choose medium-sized sweet potatoes that are more thin/even in diameter than shorter/fatter ones, and are even in size. However, also make sure they aren’t too long for your air fryer. You want them to be a good fry size.
  2. Then, cut off the ends and slice it in half lengthwise. Make sure to use a long, sharp knife. 
  3. Place each half, cut-side against the cutting board, and slice into ¼-inch slices. You can then chop those into ¼-inch pieces.

You can optionally use a mandoline for perfectly even ¼-inch slices, but be incredibly careful as sweet potatoes are fairly tough to cut through. Wear the protective glove!

How to Make Sweet Potato Fries in Air Fryer

  • Prepare the sweet potato: Preheat the air fryer to 380F/194C. Then, scrub the sweet potatoes clean, peel them if preferred (I choose not to, for extra fiber and nutrients!), and chop into ¼-inch fries (method above).
  • Season the fries: Transfer the sweet potato to a large bowl with the oil and toss with tongs to coat. Then add all the seasonings and toss once more until well distributed.
  • Air fry: Transfer the sweet potato to your air fryer basket in a single layer (cook in batches if necessary. I did 2 batches in my 8 qt air fryer), with a bit of space in between. Air fry for 14 minutes.
  • Shake halfway then serve: Shake once halfway through cooking time. Then, remove from the air fryer and serve (read below for my top serving recommendations).

If necessary, you can reheat any earlier batches for 1-2 minutes before serving.

How to Cook Frozen Sweet Potato Fries in an Air Fryer?

Whether you’ve prepared and frozen your own (method in storage section) or have a bag of sweet potato fries in the back of your freezer, it’s super simple to cook these from frozen in an air fryer.

  1. First, preheat the air fryer to 400F/205C. Then, lightly spray the fries with cooking spray or oil and season them.
  2. Spread in a single layer (with space between) and cook for 8 minutes. Then shake the basket and cook for an additional 5-8 minutes, until crisp and browned.

The time will vary based on the thickness of the fries. If you’re reheating cooked fries from frozen, it will take just a few minutes. 

Optional Add-In’s and Variations

Like regular potato fries, there are tons of ways to season these air fryer sweet potatoes. Some of my top recommendations include:

  • Spice: Add some spice to the homemade sweet potato fries with a pinch of chili powder or cayenne powder.
  • Rosemary: Use around a tablespoon of rosemary (fresh or dried) with salt and pepper (and optionally garlic).
  • Cumin: I particularly like using a combination of cumin, garlic, cayenne, and salt and pepper.
  • Oregano: Season to taste, but around a tablespoon should work well.
  • Cinnamon: A pinch of cinnamon will pair well with savory, spicy, or even sweet seasonings (with a sprinkle of sugar or sugar free sweetener (usually added in the last 5 minutes of cooking).
  • Parsley: Sprinkle the healthy sweet potato fries with finely chopped parsley for a hint of freshness.
  • Parmesan cheese: Add 1-2 tbsp freshly grated parmesan (or nutritional yeast if vegan) to the sweet potato fries in the air fryer in the last 5 minutes of cooking. This option works well with rosemary fries, too.
  • Seasoning blends: There are plenty of seasonings that will work with these homemade air-fried sweet potato fries.
    • Italian seasoning
    • Cajun seasoning
    • Chipotle powder
    • Curry powder (or Garam Masala)
    • Lemon herb seasoning
    • Za’atar seasoning
    • Chili lime (Tajin)

Tips for Best Results

  • Preheat the air fryer: This is important to maintain the correct temperature and yield the crispiest air-fried sweet potato fries.
  • Slice the fries evenly: That way, they’ll cook evenly, too.
  • Adjust their size: For the crispiest results, make matchstick/shoestring fries. Or, if preferred, make thick sweet potato wedges. Either way, adjust the air fryer time as needed.
  • When to add the seasonings: I’ll often add dry powdered seasonings at the beginning of the cooking process. However, for dried or fresh herbs, you may prefer to add them in the last 5 minutes to avoid burning them. More so, adding the salt towards the end can help yield crispier fries (but experiment and see what you think).
  • Cook in batches: Avoid overcrowding the air fryer at all costs, or else you’ll end up with soggy, limp fries. The fries should be in a single layer, with space in between.
  • Adjust the cooking time: Not all air fryers are the same and may require tweaks to the cooking time. The first time you follow this recipe, keep a close eye if they are done sooner/later than specified.
  • Allow them to ‘rest’: Once cooked, you can rest the fries on a baking sheet/wire rack for a few minutes to crisp up further before serving.

Air fryer size: This recipe was tested using my large 8-quart Cosori air fryer. If yours is smaller, cook your fries in batches so fries remain in single layer while cooking.

FAQs

How to prevent fries from getting soggy?

When using an air fryer, the main way to avoid soggy fries is to make sure you cook them in batches, spreading them in a single layer in your basket, with space in between. If you overlap or stack them, their closeness will cause them to steam rather than crisp up.

What type of oil is best to use?

You can use any neutral cooking oil, though I prefer to use options that contain heart-healthy fats like extra virgin olive oil or avocado oil, and I have never had issues with my olive oil smoking.

Can I make these oil free?

Technically, yes. Though they won’t become as crispy and made seem a little ‘dryer,’ but will still taste great. To reduce but not eliminate oil entirely, you could spray them lightly with cooking spray.

How do I make sweet potato fries if I don’t have an air fryer?

You can also bake homemade sweet potato fries in the oven. To do so, toss the fries in a little cornstarch too, when seasoning. Then, spread them in a single layer and cook at 425F/218C for 30-40 minutes, flipping halfway. Allow to rest for 5 minutes after, too, to further crisp up.

Top Serving Recommendations

You can enjoy these healthy, crispy air fryer sweet potato fries as an appetizer, snack, or side to an almost endless list of dips and meals.

What Dips to Serve with Homemade Sweet Potato Fries?

What are other serving recommendations?

Sweet potato chili fries?! Yes, you can! Use leftover turkey chili, Instant Pot vegetarian chili or buffalo chicken chili to top your fries with and don’t forget to top them up off with your favorite shredded cheese, green onions and more!

How to Make Ahead and Store the Fries?

Make ahead: You can wash, chop, and even season the raw sweet potatoes up to 8 hours in advance (or 2 days if stored in a large container of water) and store them in an airtight container in the fridge until they’re ready to air fry.

How to Freeze Sweet Potato Fries

You can also prepare the sweet potato fries to freeze. Simply slice and then blanch the fries for 2 minutes in boiling water.

Once cooked, drop them into an ice bath until completely cool. Then dry well and optionally season.

Next, flash freeze the fries in a single layer, not touching, on a baking sheet before storing them in airtight bags/containers in the freezer for up to 6 months.

Refer to the how-to section above for cooking frozen sweet potato fries in the air fryer!

Storing: These crispy sweet potato fries are definitely best enjoyed immediately for the crispest results and overall best texture. However, you can store any leftovers in an airtight container for between 3-4 days in the refrigerator.

You could also freeze the cooked fries for 3 months, though I prefer to freeze them pre-cooked (method above).

Reheat: Reheating the sweet potato is super simple and takes just minutes. Add the fries back to your air fryer and reheat for 1-2 minutes (more from frozen) at 400F/205C, until heated through. Add more time for crispier fries. You can also use a toaster oven. Avoid using a microwave unless you don’t mind them soft.
