Air Fryer Frozen Sweet Potato Fries

There are few things more comforting than a side of sweet potato fries. If a restaurant has the option for sweet potato fries, I’ll always order them! 

Fries at home have always been lackluster. I’m never up for deep frying them myself and frozen fries in the oven just don’t taste the same. 

Enter the air fryer — the device that changed everything. 

Frozen fries in the air fryer are so easy, so quick and so delicious. They are just as good, if not better (and better for you, without all that oil) than regular fries. 

Let’s get into this recipe — I just know you’re going to love how easy it is. 

Why You’ll Love This Sweet Potato Fries Recipe

In the mood for crispy sweet potato fries? You’re going to LOVE this super simple recipe. It will give you the best results in a short amount of time.

  • Frozen sweet potato fries go from cold to crispy perfection in under 15 minutes. 
  • They’re just as tasty and crispy as the ones you love at your favorite burger place without a deep fryer.  
  • Dress them up to your heart’s content with salt, seasonings, and sauces. Garlic powder makes a great addition.
  • The short cooking time means you can have an easy snack ready in a few minutes.

They’re the perfect addition to burger night! Whether you’re making smoked hamburgers or turkey burgers, everyone will love a serving of this sweet potato goodness for a quick side dish.

Ingredients for the best frozen sweet potato fries

Here’s what you’ll need for this easy air fryer recipe: 

  • avocado oil spray Don’t sub this out for olive oil or vegetable oil! More on this in the next section. 
  • frozen sweet potato fries I like to make Alexia sweet potato fries in the air fryer. Their sweet potato waffle fries are delicious.
  • coarse kosher saltYou can also use coarse sea salt. Both can be found in the seasoning aisle at the grocery store.

Salt is enough to flavor sweet potato fries in my opinion, but feel free to top them with your favorite seasoning if you like!

And don’t forget the sauce. Ketchup or aioli are both lovely, but I can’t recommend this fry sauce for sweet potato fries enough! It’s the perfect balance of cool and spicy, and so, so good! It’s my favorite dipping sauce.

Bbq sauce and honey mustard are also really great options, especially if you’re making them with cheeseburgers.

Ingredients needed to make sweet potato french fries.

Best cooking spray for the air fryer 

When it comes to the air fryer, you can’t just use regular old cooking spray. 

Surprisingly, spraying non-stick cooking spray can deteriorate the non-stick coating on the inside of the air fryer. This will make the pan unsafe to use. 

The best oil for the air fryer is avocado oil because it has a high smoke point. That means the temperature will have to be super-duper hot (570°F) before it will start to smoke and burn. 

My favorite brand is Chosen Foods.

Extra-virgin olive oil, while normally fine for other cooking methods, has a much lower smoke point, at 375°F. If your air fryer needs to be hotter than that (and it will be for these sweet potato french fries), then you should stick to avocado oil spray instead.

Now that we’ve got that important tip out of the way, who is ready for some sweet potato fries?!

First, go ahead and preheat your air fryer to 400°F for 3 minutes. 

Spray the inside of your air fryer basket with avocado oil spray. Just a light to medium spritz will do. 

Then add the frozen sweet potato fries, arranging them in a single layer. This will help them all to cook evenly. 

Then cook them at 400°F for 6 minutes. Remove the basket and give it a good shake, tossing the fries around.

Spray the fries very lightly with avocado oil spray, then return the basket to the air fryer. 

Cook for an additional 6 minutes at 400°F.

Remove the air fryer basket and sprinkle the fries with coarse salt while they’re still hot — this will help it to stick better. 

Frozen sweet potato fries in the air fryer – time and temp

Frozen sweet potato fries can cook in a preheated air fryer at 400°F for about 12 minutes. The cook time can vary depending on the size and model of air fryer, so cook them for longer in 2-minute increments if necessary. 

Be sure to toss the fries around halfway through to ensure they’re cooked evenly. 

The fries need to be cooked in a single layer, so depending on the size of your air fryer, you may need to cook them in batches, so plan accordingly. 

I like this dual-basket air fryer that can cook a single batch or a double batch at once.

Tips & Tricks for extra crispy fries

Preheating the air fryer helps the fries to get nice and crispy. Preheating only takes about 3 minutes, so turn it on while you work on another part of dinner. 

The single layer of fries is absolutely key to getting the fries super crispy. If they are too crowded, the air can’t get around them, and they tend to be soggier. Air fry them in batches if needed. 

Don’t skip the step of moving them around halfway through! This is also important to ensuring crispy perfection every time.  

You may need additional time to get them crispy based on your model of air fryer. Cook them for longer in 2 min increments if needed. 

Don’t throw out those leftover fries! Toss them in an airtight container in the fridge. They’ll stay fresh for up to 3 days. Just take the leftover sweet potato fries and heat them up in the air fryer when you’re ready to eat them.


Are frozen sweet potato fries healthy?

Frozen sweet potato fries that are cooked in the oven or the air fryer don’t get fried in lots of unhealthy oil. If you merely use a spritz of avocado oil on the fries and in the air fryer basket or baking sheet, they will be much healthier than the regular kind. 

Why won’t my sweet potato fries get crispy?

Arranging frozen fries in a single layer for either the air fryer or oven is key to making sure the air can circulate and crisp each fry. Make sure to toss them halfway through, as well. 

Why do my sweet potato fries turn out soggy in the air fryer?

If you overcrowd the air fryer with fries, the air cannot circulate and the fries will become soggy. Be sure to arrange them in a single layer, working in batches if needed. 

Should frozen fries be thawed before air frying?

There is no need to thaw frozen fries before air frying. They will become nice and crispy when added to the air fryer frozen.
