Peel and slice sweet potatoes into desired size of fries.
Toss the fries in the oil. It will provide an extremely light coating.
Spray the air fryer basket with oil and place fries in the basket. Leave space for the air to flow.
Cook on 400 for 10 minutes. Shake fries at the 5-minute mark. Cook for longer as needed.
Remove fries and salt to taste immediately.
Sizing: Depending on how thick or thin you cut the fries the cooking time will vary. So just watch the sweet potato fries closely. Instant Pot Duo Crisp and Ninja Foodi Directions - Use the air fryer crisping lid on both devices and cook the same way. Since the basket is a bit smaller you might need to batch cook your fries. Oven directions: Preheat the oven to 425 degrees and cook for 5 minutes, flip, and cook another 5 minutes and check. If you have smaller fries they will be done or close to done. Larger fries will take longer. Dipping Sauces: Simple ketchup or even bbq sauce is a great dip for sweet potato fries. You will also find many enjoy mixing mayo and bbq sauce together for a dipping sauce.Overlapping: Don't overlap the fries as they won't crisp up. Do in batches as necessary.Presoaking Sweet Potato: To remove some of the starch and allow the fries to crisp up even more, soak the fries for 20-30 minutes prior to prepping. Storage: These will soften as leftovers in the refrigerator. If reheating, only use a toaster oven or the AF for about 3-4 minutes at 375-400 degrees. Store in a sealed container in the refrigerator for up to 3 days. Limp or Mushy Fries: This happens when 1. There is too much oil on the fries. Please note that I am suggesting you use OLIVE OIL SPRAY and not dump olive oil or any oil when mixing. 2. There is no air circulating in the AF. Please note that it is important to NOT CROWD when using an AF. There has to be air in between each piece of food for them to crisp up. When food is piled on or sticks to each other when cooking, the entire concept of using an AF is lost. Cooking Multiple Batches: If you need to cook in batches because of the size of AF, put the first batches in a low temp oven to keep warm while cooking the others. Meal Prep Option: Peeling and cutting the fries up to 3 days early and store in a sealed container. When ready to cook, remove from container and proceed with the recipe as stated.
