Wash and peel the carrots and cut them diagonally into thin slices. Cook the pasta in boiling salted water for about 8 minutes. Drain and fill into an ovenproof casserole dish. Bring stock, cream and 6 tablespoons of wine to the boil.
Add the carrots and cook for about 3 minutes. Season with salt, pepper and nutmeg and pour over the noodles. Wash the chicken fillets, dab dry and cut them deep lengthwise. Fill each fillet with 2 slices of Parma ham and 1-2 sage leaves.
Season the fillets with salt and pepper and place them on the noodles. For the crust, mix cheese, breadcrumbs, egg yolk and remaining wine and spread on the fillets. Bake in the preheated oven (electric cooker: 200 °C/ gas: level 3) for 30-35 minutes.
Serve garnished with sage as desired.
