Clean, wash and slice the zucchini lengthwise. Cut them into strips as wide as noodles. Cook the noodles in 4-5 l boiling salted water (1 teaspoon salt per litre) according to the instructions on the packet.
Approximately 2 minutes before the end of the cooking time, add the courgette strips and cook. Pour off, collecting 1⁄4 l cooking water. Dissolve stock in it.
Preheat oven (electric cooker: 225 °C/circulating air: 200 °C/gas: see manufacturer). Grease one large or several small casseroles. Halve the clove of garlic and rub the cut surface into the dish(s).
Cut the salmon into wide strips, mix with the pasta and courgette mix and distribute in the moulds. Wash the dill, shake dry and chop coarsely. Mix with cream and stock, season with salt and pepper.
Pour over the pasta mixture. Sprinkle cheese over it. Bake in a hot oven for about 15 minutes.
