Taste and texture:
When cooked in an air fryer, sweet potato fries turn out nice and crispy on the outside, yet soft and tender on the inside. You can change up the flavour by adding your own seasonings and by serving them with your favourite dipping sauce.
Key ingredients:
A bag of frozen sweet potato fries - Trader Joe's sweet potato fries, McCain sweet potato fries and Alexia sweet potato fries are a few popular brands, but any brand that you can find in your grocery store will do. You can also use homemade, frozen sweet potato fries too.
If you cook a different type of frozen sweet potato fries such as sweet potato waffle fries, shoe string fries, steak fries, or curly fries, you may need to adjust the cooking time based into the thickness of the fries.
How to cook:
Step one:
First, place the frozen sweet potato fries on the trays of your air fryer or in the basket of your air fryer and cook them for 12-15 minutes at 400 degrees Fahrenheit, flipping the fries half way through, or shaking the basket half way through to help the fries cook evenly.
Step two:
When the fries have finished cooking, sprinkle them with salt, pepper, and any other seasonings that you like (note: if your fries are pre-seasoned you can likely skip this step).
Chef's tips:
- Every model of air fryer is different, so you may have to adjust the cooking time if you are using a different model.
- Depending on the size of your air fryer, and the size of the bag of sweet potato fries that you buy, you may have to air fry the fries in batches.
- For the crispiest sweet potato fries, be sure to leave some space around the fries so the air can circulate and cook better.
- Try not to overlap the sweet potato fries when they are in the air fryer or they won't cook as well.
- If your sweet potato fries are pre-seasoned, don't worry about adding any seasonings. If they are not pre-seasoned, season them however you prefer once they have finished cooking. I love salt and pepper with a little cinnamon.
- Serve sweet potato fries plain or with your favourite ketchup, aioli or bbq sauce.
How to serve:
Sweet potato fries are such a fun side dish that can be eaten on their own but I also love pairing them with any type of burger including hamburgers, turkey burgers or duck burgers, or steak, lamb chops, fish sticks, scallops, sausages, chicken fingers or chicken tenders or chicken wings.
How to store:
If you have leftover cooked sweet potato fries, store them in an airtight container in the fridge for up to 5 days.
How to reheat:
If you end up with any leftover fries after you've cooked them you can easily re-heat them in your air fryer. To do so preheat your air frier to 400 degrees Fahrenheit, then cook the sweet potato fries for 1-2 minutes until heated through and crisp (depending on the model of air fryer you use you may have to adjust the cooking time slightly so just be sure to watch them closely).
