Cut the tips off the sweet potato and peel the skin.
Cut into long, thin and even strips. The more even they are, the more evenly they will cook.
Optional: Soak them in water for 15 minutes. As my notes mentions, I personally did not find a significant difference between the soaked and un-soaked batches.
If you soaked the sweet potatoes, dry them with a clean kitchen napkin.
Into a mixing bowl, add the sweet potato strips. Add the avocado oil and mix well with your hand (or spoon) until the oil is evenly coated on all sides.
Preheat the air fryer at 370F for 2 minutes. Place the sweet potato strips in a single layer in the air fryer basket, spreading them out as much as possible.
Air fry for 5 minutes at 370F.
Empty the fries back into the mixing bowl. Add turmeric powder, salt, freshly ground black pepper and cayenne pepper powder. Mix everything well. Return the fries to the air fryer, layer them in a single file as before and air fry for an additional 5 minutes.
Check and remove any browned fries that are ready. Fries may cook at slightly different rates, due to varying thicknesses. Fries will usually crisp up once removed on a plate.
Serve with Hummus sprinkled with paprika powder or with spicy sriracha sauce.
Notes
Several tips and tricks to make these delish sweet potato fries:
Cut your sweet potato slices so they are all approximately the same length and thickness. Using a mandolin will help you slice them evenly and thinly.
Some people suggest soaking the sweet potato strips in water for several minutes. I have tried both ways, and the end results are pretty much identical. So, soaking is optional.
Don't overcrowd the air fryer basket. The sweet potato fries need to be placed in a single layer in the air fryer basket. This is to make sure that the fries cook evenly. If you don't own a larger air fryer, then plan to make several batches.
Air fryer times vary, so you need to open the basket a few times to check on progress.
It may take a few tries to get the hang of this recipe, but the journey itself is a wonderful experience. Hang in there and don't give up and head to the nearest fast-food restaurant!
You can get creative on what you want to add to your sweet potato fries. A few seasoning suggestions are turmeric powder, chili or cayenne pepper powder, freshly ground black pepper, rosemary or other herbs, garlic or/and onion powder. And a dash of salt, of course.
Once you have the basics down, you can also use this recipe as a guideline to make any kind of potato fries. You can use regular russet potatoes, purple potatoes or Yukon gold potatoes.
