Being the mom to a toddler and hungry husband is not always easy. I love cooking all kinds of food, but sometimes I just don’t have the time. Luckily I am able to use my air fryer as a shortcut to getting healthy food on the table fast. 

I especially love using my air fryer to cook frozen foods quickly and easily! Using the air fryer to cook frozen sweet potato fries is a life saver. I just dump them into the air fryer basket and they are perfectly crispy on the outside and tender on the inside in less than 15 minutes!

Shouldn’t I just use the directions on the packaging?

Since the air fryer is a small convection oven, it uses dry heat to circulate air around the food making it cook fast. This means that the time and temperature may need to be adjusted and will be different from what’s on the package instructions.

💗 Why You’ll Love Making Sweet Potato Fries in the Air Fryer

Fewer dishes and cleanup. When I make fries in the air fryer, I don’t need to haul out and clean a big baking sheet or need to use any parchment paper. They cook right in the basket with little mess! 

Better texture. If you ever have had a french fry made in the air fryer, you’ll know that the crispy texture is unmatched. By using dry circulating heat, the air fryer cooks all around the fry making it crisp up perfectly. 

They cook much faster. Cooking a bag of frozen sweet potato fries takes almost double the time whereas this air fryer method takes 15 minutes or less.

🥣 What You’ll Need

Frozen Sweet Potato Fries – You can find these in just about any grocery store these days. You can also find them in wedges, crinkles, or even fun-shaped waffle fries. Most bags are about 1 pound which is the perfect amount to serve a family of 4. 


Air Fryer or Ninja Foodi – Your favorite air fryer will do the trick. There are so many brands out there these days, but my favorite one I use every single day is my Ninja Foodi all in one and Ninja Foodi Grill. I like that they have more functions than just air frying and we use them multiple times a day!

🍠How To Air Fry Frozen Sweet Potato Fries

1️⃣ Preheat your air fryer to 400F. This will take about 3-5 minutes depending on your air fryer.

2️⃣ Place the frozen sweet potato fries at the bottom of the air fryer basket in a single layer. It’s ok if they overlap a tiny bit, but you want to make sure the dry heat crisps the fries instead of steam them. If your air fryer is too small, you may have to cook in batches.

3️⃣ Set your air fryer to cook for 15 minutes. Flip at the 7-8 minute mark and then again at 10 minutes. At 12 minutes of cooking time, check to see if they are done and crispy. If they are, take them out. If not, let them cook for the additional 3 minutes to finish cooking.

4️⃣ Remove sweet potato fries from the air fryer basket with tongs and serve hot with your favorite side dishes and dipping sauces.

How long do you cook sweet potato fries from frozen in the air fryer?

Generally, most frozen sweet potato fries will cook thoroughly in 12-15 minutes if flipped once or twice halfway through.

Should I add oil to frozen french fries when using my air fryer?

No need! Frozen french fries are typically seasoned already and have a layer of oil on the outside that helps them crisp. The air fryer will crisp up the outside using dry heat without the use of any additional oil.

What temperature do you air fry frozen sweet potato fries?

You can air fry frozen french fries at a temperature between 375F and 400F. At 400F it may take a few minutes less but you’ll need to make sure you keep tossing the fries to keep them from burning.

Are air fryer sweet potato fries healthy?

Cooking sweet potato fries in the air fryer are much healthier than frying them in oil because they don’t use any excess oil that would add more fat to the mix.

Do I need to preheat my air fryer?

Generally for frozen foods, I like to preheat my air fryer. Once the dry heat starts circulating the moisture evaporates immediately whereas if there is no preheating, the air fryer may steam the fries making them too soggy.

Can I add aluminum foil to my air fryer?

This depends on the type of air fryer you have and where you’re putting the foil. I like to put the foil UNDER the basket to catch any excess oil or grease that comes off the sausage. This eliminates the need to clean the entire air fryer and you’ll just use the basket. If the foil is in a position where it can become loose, it may get sucked into the heating element when the air circulates so be sure it’s weighed down properly.
