Notes

Soaking the sweet potato fries is crucial for removing excess starch and preventing sogginess. Make sure to dry the fries thoroughly before tossing them with oil and seasonings. Don't overcrowd the baking sheet; bake in batches if necessary to ensure proper airflow. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or air fryer to maintain crispness.
