Peel and cut sweet potatoes into 1/4 inch sticks.
Soak them in water for about one hour, remove and pat dry.
In a large bowl, toss sweet potato sticks in olive oil.
Place one layer of sweet potatoes on air fryer. Do not layer them. You will have to cook them in batches to make sure they are nice and crispy!
Cook for 6 minutes at 375 degrees.
Meanwhile, make Avocado Ranch dressing according to instructions.
After six minutes, sprinkle fries with salt and pepper, flip, cook for six more minutes.
Flip fries one more time and cook for 2 more minutes.
Remove from Air fryer, add salt and pepper to taste and optional Parmesan cheese.
Repeat steps 3-9 as needed for remaining sweet potato fries.
Serve with optional avocado ranch or dip of choice!
