Peel, wash and slice the potatoes and beetroot. (It is best to wear rubber gloves when peeling beetroot.) Wash chicken legs, pat dry and season with salt and pepper.
Line a baking tray with baking paper and brush lightly with oil. Put chicken legs in the middle, spread beetroot and potatoes all around. Press garlic with skin through a garlic press and add.
Sprinkle beetroot and potatoes with sea salt. Roast in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 45 minutes, turning after approx. 25 minutes. In the meantime, pluck parsley leaves from the stalks, wash, dab dry and chop finely.
Mix crème fraîche, paprika, lemon juice, sugar and parsley. Arrange chicken legs, vegetables and potatoes on a plate. Add crème fraiche as a dip. Garnish with parsley and lemon peel.
