Wash the sweet potato, optionally peel it, and cut it into slices. Then, cut each slice into fries (sticks). In a bowl, mix the olive oil with sweet paprika, spicy paprika, smoked paprika, turmeric, and curry. Stir well. Dip each sweet potato stick into the marinade, ensuring they are evenly coated with the seasoned oil.

Preheat the oven to 200°C. Line a baking sheet with parchment paper. Spread the sweet potato fries evenly on the sheet, ensuring they do not overlap. Bake in the preheated oven for 10-20 minutes, depending on the thickness of the fries and your preferred level of crispiness. Watch closely to prevent burning.

Serve on a plate and optionally season with a pinch of salt.
