Star Ingredient – The Sincere Sweet Potato

Though we think of sweet potatoes as being part of the potato family, they’re actual the sweet roots of the morning glory family. Isn’t that weird and wonderful? A yam, on the other hand, is just like an everyday potato (or vegetable tuber). Today, we’re setting our sights on the simple sweet potato.

A single sweet potatoes offers:

  • High in Vitamin A
  • Rich in vitamins B and C
  • Loaded with minerals such as calcium, iron, magnesium, phosphorus, potassium, and zinc
  • Great amount of fiber (about 4 grams)
  • Full of healthy complex carbohydrates
  • A small amount of protein (about 2 grams)
  • Low in calories

Are Frozen Sweet Potato Fries Healthy?

Good question! The answer is––it depends on how you define healthy. While they are healthier than other junk food like chips, candy, or colas, they are still fried in oil before freezing. Plus, they usually have additives and preservatives. But, they are preferable over fast food fries.

Sometimes, you can find a brand that has very few ingredients; such as only sweet potatoes, salt, and oil. If you can find a brand like that, even better. For the healthiest alternative, try our air fryer sweet potato fries recipe which uses fresh instead of frozen sweet potatoes.

How To Serve Up Your Sweet Potato Fries

Sure, you can eat these scrumptious sweet potato fries right out of the basket, but here are a few ways to enjoy them to add a little more nutrition (and extra flavor). Remember––they’re best eaten hot as soon as they’re done, so plan your potato meals accordingly.

  • Make Your Salad More Satisfying – Move over croutons! Adding a serving of sweet potato fries to your salad will give you a crispy component, as well as added fiber and some plant-based fat.
  • Savory Sauce Suggestions – If you don’t like sweet or spicy sauces, these sweet potato fries are also delicious dipped in spicy maple mustard (see recipe card for details), creamy dill dressing, ketchup, or vegan ranch or mayo.
  • Perfect Lunch Pita – Pack an on-the-go lunch including a pita pocket filled with chopped veggies, greens, hummus, and fries. Wrap in a piece of parchment paper along with a piece of fruit, a handful of nuts, and a bottle of water or herbal tea. Easy and delicious!

Helpful Tip: Add a medium-sized lettuce leaf (romaine works well) to the bottom of your pita before you add any veggies or hummus. This helps to keep the bottom of your pita bread dry so it doesn’t get as wet or disintegrate as quickly.

How Do I Store My Leftover Air Fryer Sweet Potato Fries?

We all know how icky and limp fries can get once they’re left out on the counter for a while or after they’ve been in the fridge overnight. Even though it’s tempting to throw any leftover fries away, don’t do it! You can easily reheat these fries in the air fryer.

To reheat french fries (or, in this case, sweet potato fries) in the air fryer, first preheat the oven at 400 degree for 5 minutes. Then, place fries in a single layer into the air fryer basket and cook for around 4 minutes at 350 degrees. If you like them a little less crisp, check them at 3 minutes. If you want them extra crispy, cook for another minute more.

Frequently Asked Questions

Does this recipe work for any type of frozen fries?

For the most part, yes. Frozen sweet potato fries are a little more fragile than regular potatoes, so they may need a shorter time in the air fryer. But, if keep an eye on your fries and check them often, you’re sure to get just the right consistency when cooking.

Do I have to use a certain brand of frozen sweet potato fries?

Not at all. We used the Alexia brand and also the 365 Whole Foods brand to test for this recipe and they both came out great. The only thing to keep in mind is the quantity that you add to your air fryer. Some bags have a small amount of fries, while others have lots. If you try to keep it to a sort-of-single-layer amount, it should be fine.

How do I keep my fries from getting soggy?

Our best advice is to eat the fries right away, as soon as they’re done. Plan on air frying the quantity you’ll eat in one sitting so that you won’t have leftovers. But, if you do have extras, you can put them back into the air fryer at 350 degrees and cook for about 3-5 minutes to crisp them up again.

Incredibly fast and flavorful sweet potato fries that you can make right from the freezer! Here’s how to make the perfect frozen sweet potato fries in an air fryer. The outside is satisfyingly crisp, while the inside is soft and fluffy. You’ll find this spicy air fryer snack really fun to make and even more fun to eat. Keep them plain for spice up your fries with the optional additions we list in the recipe!



Main Ingredients:

  • ½1 bag of frozen sweet potato fries (I used the Alexa brand, but the 356 Whole Foods brand is very good, too.)
  • Optional: Spray Oil (I used avocado oil)
  • Optional: ¼ teaspoon of cayenne pepper (if you like spicy fries)
  • Optional: ½ teaspoon of black pepper (if you like peppery fries) 

Spicy Maple Mustard Sauce Ingredients:

  • 4 tablespoons of maple syrup
  • 2 tablespoons of Dijon mustard
  • ¼ teaspoon of dry mustard powder
  • ½ teaspoon of garlic powder
  • ¼ teaspoon of cayenne pepper (or to taste)
  • Squirt of sriracha or hot chili paste (optional)


  1. If your air fryer requires preheating, preheat the air fryer at 400 degrees for 5 minutes.
  2. OPTIONAL: If you’d like to add spices, add frozen fries to a large bowl and spritz with a little bit of spray oil. Stir. Sprinkle on the black and/or cayenne pepper and mix. If you prefer plain fries, skip this step.
  3. When the air fryer is ready, dump half the bag of frozen sweet potato fries (or however many will fit) into the air fryer basket, arranging the fries to lay flat leaving some room for the air to move around them.
  4. Cook at 400 degrees for 8 minutes. Shake or flip the fries over and cook for another 7 minutes at the same temperature.
  5. While they’re cooking, make the Spicy Mustard sauce. In a small bowl, mix all of ingredients together. Whisk until well blended. Put aside for later.
  6. Serve your seasoned fries along with the Spicy Mustard Sauce or dip of choice. Enjoy while hot.


  • Cooking Time – Because some air fryers are different, it might take you a little more or less than 15 minutes for the fries to be done. Check on the fries halfway to see how they’re doing. When golden brown and crispy, it’s time to take them out.
  • These air fryer sweet potato fries are vegetarian, dairy-free, soy-free, gluten-free, nut-free, sugar-free, plant-based, and totally delicious!
