Keep in mind that baking time may vary depending on how large you cut your sweet potatoes and how accurate your oven is. Ovens often run a little cold or hot. We like to keep the skins on for sweet potato fries, but if you prefer them without, go ahead and peel them.

Preheating baking sheets inside a 450 degrees F oven is the single most critical step for achieving a crisp exterior on high-moisture root vegetables. Cold metal slows initial moisture evaporation, leading to soggy results rather than proper browning. When slicing the tubers, maintain uniform one-half-inch thicknesses to ensure even cooking rates across the batch. Swapping olive oil for avocado oil works well due to identical fat ratios and higher smoke points, though neutral seed oils will yield a less savory profile.
Raw sweet potatoes do not freeze well due to their high water content, which ruptures cell walls upon thawing and turns the flesh mealy. Cooked fries store much better in the freezer for up to three months when flash-frozen on sheet trays before bagging. Reheating requires returning them to a 425 degrees F oven for eight to ten minutes. Microwaving thawed fries destroys texture entirely, turning them limp instead of restoring their surface crunch.
