Peel the turnips and cut into strips. Dip the strips in boiling water for 1-2 minutes. Drain and cook again in fresh water for 5 minutes. The beet taste is lost a bit, which is more reminiscent of French fries made from potatoes. Drain, let cool.
Mix the turnip strips well with the salt and oil, this is best done with both hands. Preheat the oven to 240 ° C and let the french fries turn lightly brown and cooked through. This takes about 30-40 minutes. It depends on how cooked the turnip was and how big the strips are.
