Heat oven to 200C/180C fan/gas 6. Put the sweet potato through your spiralizer using the large noodle attachment. Lay the noodles out on a large baking tray and drizzle with the olive oil, toss well to coat the noodles making sure they end up as a single layer.
Bake in the oven for 20-25 mins, tossing around in the tray half way through cooking, until tender and starting to crisp up and char at the edges.
While the fries are baking mix all of the seasoning ingredients together in a bowl and add 1/4 tsp black pepper and 1/4 tsp salt. Stir well and set aside.
When the fries are ready evenly scatter over the seasoning while they are still hot then transfer to a serving dish.
