  • Air frying produces crispier fries than the oven and is less messy than deep frying.
  • Preheat the air fryer, and use the proper cook time for the kind of french fry you're making.

Frozen french fries are a convenient snack food and a total crowd-pleaser. All of the hard work is done for you, so all you have to do is retrieve them from the freezer and heat them up. While you can use the oven or even a deep fryer, there's a better option: the best air fryer.

"You'll get crispier results than baking fries thanks to the convection," says Breville product expert, Karen Diep. Plus, it'll be faster, shaving off a third or more of the cook time. Many frozen fry brands include instructions for deep frying, but you'll be trading crispy fires for a real mess and a ton of used oil. "Air frying is a great alternative to getting crispier fries without the excessive fat that comes with deep frying," says Diep.

Cook times for different types of frozen french fries

Many frozen french fry brands now include air fryer instructions right on the bag. "I would recommend using the instructions indicated on the package as the manufacturer will have developed and tested the product many times," says Diep.


If the fries don't include instructions, the cook time will vary depending on the kind of fry and the thickness. This chart is a good starting point, but keep a close eye on the fries as they cook.

Type of fryCook time
Regular8-12 minutes
Waffle9-13 minutes
Crinkle-cut10-14 minutes
Sweet potato8-12 minutes
Shoestring6-10 minutes
Steak10-14 minutes

Quick tip: There's no need to defrost french fries. "I recommend that frozen french fries be kept completely frozen before using," says Diep. Thawing the fries will result in sad, soggy fries, so take them out of the freezer just before cooking.

If the frozen french fries include air fryer instructions, reference them to determine the temperature and a ballpark cook time. How many fries you can heat at once will depend on the size of your air fryer.

  1. Preheat the air fryer. Diep notes that a preheated air fryer is essential for the crispiest fries. If your frozen fries don't include air fryer instructions, Diep recommends "reducing the temperature by 25 degrees Fahrenheit, which is a general recommendation for all conventional to convection oven conversions." For example, if your package calls for baking at 425 degrees Fahrenheit, preheat your air fryer to 400 degrees Fahrenheit.
  2. Arrange the fries. Add fries to the basket in a single layer. Diep points out that overcrowding the basket will lead to soggy fries, so it's best to cook in batches rather than to overlap the fries.
  3. Air fry. Set the timer according to the package instructions or, depending on the type of french fry you're heating up, use the lowest timing listed in the chart divided in half. For example, if you're heating crinkle-cut fries, set the timer for five minutes.
  4. Toss. Once the timer goes off, give the fries a good toss and spread them out again. Set the timer for the remaining cook time, checking often to make sure they don't brown too much.
  5. Serve. Once the fries are nice and crisp, remove them from the air fryer. Serve hot. If desired, repeat with more fries.

Insider's takeaway

If you want crispy fries with minimal clean-up, the air fryer is the best choice for heating up frozen french fries. Be sure to preheat your air fryer and don't overcrowd the fries in the basket. The cook time will depend upon the thickness of the fries, with thin varieties like shoestring taking less time than thick ones like steak fries.
