Preheat the oven 425 F.
Place all your seasoning in a dish and mix together.
Cut your sweet potatoes in long and skinny fries (you can keep the skin on, or peel). We usually do this by cutting down one side, and using that new flat side as a base to hold your sweet potato down.
The skinnier the fry, the better it bakes.
Place sweet potato in a large bowl to mix, drizzle oil overtop and then your seasoning. Toss the fries thoroughly, so all of them are coated with oil and seasoning.
Take a large baking tray and line with parchment paper (you may need 2 trays depending on size).
Place the sweet potatoes in a single layer (with space between them) on your tray. This step is crucial for the best baked fries, when you overcrowd they end up coming out mushy.
Bake for 20 minutes, turn your trays around in the oven, and bake for another 10 minutes.
They should come out a bit crispy, if they feel soft, cook another 5 min.
