Preheat oven to 425 degrees.
Line baking sheet with parchment paper.
Peel and cut sweet potatoes into strips.
I did mine quite thin, however, you could cut them to a ½ strip or a wedge.
Combine all spices together.
In a large bowl, whisk egg whites.
Add sweet potato strips and toss to evenly coat.
Pour the spice mixture over potatoes and toss again.
Lay sweet potato fries onto parchment and evenly space.
Make sure the fries are in a single layer and allow a little bit of space between fries.
This allows for better cooking.
Bake for 15 minutes and flip each fry with tongs.
Cook for another 10-15 minutes until fries are cooked, but not burnt.
Remove from oven.
