Peel and finely chop the onions. Cut the bacon into small cubes. Clean and wash the chanterelles and let them drain on a sieve. Wash parsley and dab dry. Put some parsley aside for garnishing, remove remaining leaves and chop finely.
Boil up plenty of salted water. Add ribbon noodles and cook over high heat for about 8 minutes until bubbly. In the meantime, heat oil in a pan. Leave out bacon cubes in it. Fry the onion cubes in the bacon fat until translucent.
Add the chanterelles and sauté while stirring. Deglaze with vegetable stock and bring to the boil. Season the chanterelles to taste with salt, pepper and paprika. Stir in crème fraiche. Sprinkle the sauce with chopped parsley.
Put the noodles on a sieve and let them drain. Serve with the chanterelles on plates. Garnish with parsley and serve immediately.
