Peel 250 g carrots, wash and slice lengthwise with the peeler. Wash the parsley, put some aside for garnishing, and remove the leaves from the remaining parsley.
Season the roulades with salt and pepper, top with bacon, carrot slices and a few parsley leaves. Roll up the roulades and pin them with wooden sticks. In half of the hot fat roast, deglaze with 1/4 litre water and red wine.
Add the bay leaf and stew covered for about 1 1/2 hours. Meanwhile peel the remaining carrots, cut them in half crosswise and also slice them. Peel and halve the onions and cut them lengthwise into thin slices.
20 minutes before the end of the cooking time, sauté the onions in the remaining fat, add the carrots, cover and cook over a mild heat for about 15 minutes. Season with salt and coarse pepper. Remove the roulades from the stock and keep warm.
Boil up the stock. Mix cream with flour and stir into the boiling stock. Let simmer for 5 minutes and season with salt and pepper. Arrange roulades on the vegetables, garnish with herbs. Serve with sauce.
Spätzle with chopped parsley go well with it.
