Cut sweet potatoes into fries of consistent thickness (about ¼-inch) so they cook evenly and achieve the same level of crispiness on the outside while remaining creamy inside.

Pat cut sweet potatoes completely dry with paper towels before tossing with oil and seasonings—excess moisture prevents browning and creates crispy exteriors instead of soggy fries.

Warm the ground cinnamon in the olive oil for 30 seconds before coating the potatoes to bloom the spice and intensify its warm, complex flavor throughout the dish.

Add salt and any additional cinnamon while fries are still hot and slightly wet from steam—they'll adhere better and distribute more evenly than seasoning cooled fries.

Spread fries in a single layer on your baking sheet without crowding; overlapping potatoes trap steam and prevent the crispy texture that makes this dish truly addictive.
