Preheat the oven to 220 °C (200 °C fan) and line a baking tray with baking paper. Wash the sweet potatoes thoroughly and cut them into even wedges.
Toss the sweet potato wedges with the cornflour in a large bowl until they are lightly coated. Then add the olive oil and paprika and mix everything well.
Spread the wedges out on the tray with a little space between them. Bake at 220 °C for 25–30 min, turning once, until they are soft and lightly browned at the edges.
Meanwhile, stir the natural yoghurt with the chives, lemon juice, garlic powder and a little sea salt until smooth. Leave it to stand briefly so the flavours come together.
Season the sweet potato wedges with sea salt as soon as they come out of the oven. If you like, give the dip another stir before serving.
Serve the baked sweet potato wedges warm with the herb dip.
Good to know
Lightly crispy on the outside, soft and satisfying inside. A tray like this often disappears faster than you'd think. The dip keeps it fresh without much effort.
