Peel and finely dice the onion. Peel the carrots and cut into sticks. Roughly chop the parsley. Cook the noodles in plenty of boiling salted water until they are firm to the bite.
Heat the butter in a pan and fry the onions in it for about 2 minutes. Add the carrots, curry and a pinch of salt and fry on a low heat for about 5 minutes. Add the parsley, cream cheese and milk, stir evenly and bring to the boil. Season the sauce with salt and pepper.
