Ingredients
I made some important helpful notes and substitutions about ingredients. For the exact measurement and printable version of this Air Fryer Sweet Potato Fries (Ninja Foodi) Recipe, check the recipe card below.
- White Sweet Potatoes - In Asia, white sweet potatoes are more popular and easy to find. You can use any sweet potatoes that are available to you. In the US, orange sweet potatoes are available in all grocery stores nationwide.
- Seasonings - The perfect seasoning for this sweet potato fry recipe is garlic powder, cumin, paprika, cayenne pepper for some heat, thyme powder, and salt and pepper. It is the same versatile seasoning mixture I use for the blackened fish taco recipe.
- Cooking Oil - I use neutral-tasting oil that is highly heat tolerant such as avocado oil. Coconut oil is also a good choice, but there is a hint of coconut taste which is also a good flavor.

Step 1. Clean and cut the sweet potatoes into french fry slices, about ½-1/4 inch thick. It can be peeled or skin-on, it’s up to you. I peel mine because that's my son's preference.
Step 2. Combine all herbs and spices, and avocado oil in a large bowl and mix thoroughly into the sliced sweet potatoes.
Step 3. Transfer the sliced potatoes to the food ninja air fryer basket, ensuring the basket is not overcrowded. Brush the potatoes with the oil and seasoning mixture until they are well coated on the top.
Step 4. Place into the air-fryer at 400 Fahrenheit for 10-12 minutes, flipping or shaking halfway through. The time may vary depending on your desired crispiness.
Check for doneness: Use a fork or knife to check if the sweet potatoes are tender inside. They should have a crisp exterior and a soft creamy interior.
For the sauce, I use my 5-ingredient healthy sweet and sour sauce recipe. You can use your favorite dipping sauce.
Equipment

Storage
Store the air-fried sweet potatoes in a glass container in the fridge for up to 3 days. The texture may turn soft when it gets to room temperature, but you can reheat them and crisp them up.
To reheat, place them back in the air fryer basket and spray some oil to achieve crispiness. Reheat at 350F for a few minutes until warm and crispy.

FAQ
Yes, you can air-fry a whole sweet potato. Just make sure to piece them a few times with a fork to allow the steam to escape and avoid from bursting. Cook them at 400F for about 40-50 minutes, or until tender. Depending on the size, you may need to cook them shorter or longer. Keep them checked after 30 minutes from time to time.
It depends on your personal preference. Sweet potato skin is edible and provides additional nutrients and fiber. However, if you prefer a softer texture or want a more uniform appearance, peeling them is recommended.
To prevent sticking, make sure to lightly coat the sweet potato pieces with oil before air frying.
Yes, frozen sweet potato fries can be cooked in an air fryer. The cooking time and temperature may need to be adjusted according to the package instructions and personal preference. I recommend preheating the air fryer and cooking the frozen fries in a single layer for the best results.
