Stir in the oysters and cook for about 2 minutes until they start to curl.
Pour in the fish stock or clam juice, and bring to a simmer.
Once simmering, add the heavy cream and stir well. Season with salt and pepper.
Cook for another 3-5 minutes until heated through.
Serve hot, garnished with chopped parsley.
Notes
Store leftover oyster stew in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stove over low heat. Avoid freezing as it can affect the cream's texture.
