Thaw the prawns. Peel and devein the unpeeled prawns after defrosting.
Cook the pasta in plenty of salted water until al dente.
In the meantime, heat the oil in a large pan. Fry the onion, garlic and chili peppers while stirring. Deglaze with the cream and vegetable stock and simmer everything over a medium heat for a few minutes until creamy. Depending on your taste, remove the chilli peppers or leave them in.
Put the prawns in the sauce. Season with salt, pepper and lemon juice. Add the white wine and let it simmer over a mild heat (do not boil!) Until the pasta is ready. Finally mix the parsley into the sauce.
Drain the pasta and let it drain briefly. Mix with the sauce and serve immediately.
Tip: Possibly some freshly grated Parmesan with it.
