Peel the potatoes and cut into 1 x 1 cm wide sticks. Mix with the french fries and paprika in a bowl. Immediately distribute the potatoes on the baking sheet, otherwise they will draw water, and the fries should not be on top of each other.
Put the tray on the middle rail in the preheated oven and bake for about 30 minutes.
After 30 minutes, turn the fries once and set the oven to 200 ° C. Bake for another 15 minutes.
