Peel the beetroot, sweet potatoes and onions, cut into pieces suitable for casseroles and place in a casserole dish. Brush everything thinly with oil and sprinkle with the ground pepper.
Melt some herb butter in a small saucepan and toss the pressed or finely chopped garlic in it. Deglaze with white wine, add crème légère and paprika powder. Pour in a little vegetable stock and finally melt the cream cheese in it. If you like, let the sauce boil down a little. Baste the vegetables with it and place in the oven for approx. 20 minutes at 180 - 200 degrees. Then sprinkle with cheese and bake in the oven for another 15 minutes.
Sprinkle the chopped parsley on top before serving.
