Preheat the oven to 425 degrees fahrenheit.
Spiralize the sweet potato and place it on a sheet pan. Drizzle the oil and sprinkle the spices on top, then use your hands to mix it all together until each piece of sweet potato is coated.
Cook the sweet potato for 20-25 minutes, or until crispy. The pieces along the outside edge may cook faster, so keep an eye on them and rotate as necessary.
While the sweet potato is cooking, mix together the ingredients for the garlic aioli in a small bowl, until well combined.
Remove the sweet potato fries from the oven and serve with the garlic aioli.
