Clean and wash the zucchinis and leeks and cut them diagonally into slices. Briefly fry the vegetable slices in a pot in portions in clarified butter, season with salt and pepper and lift them out with a skimmer. Add stock, crème fraîche and soup paste to the pot, bring to the boil and season with salt, pepper and paprika. Fold in half of the prawns. Grease a flat casserole dish of about 1 1/2 litres.
Spread the vegetable slices in the dish, salt the plaice fillets, fold half of them over and place them on the vegetables. Pour sauce over it. Bake in a preheated oven (electric: 200 °C/ gas: level 3) for 20-25 minutes. Garnish with dill and the remaining prawns
