  • Pour in the heavy cream, stirring to combine with the onion and rosemary. Allow it to simmer gently for about 5 minutes.
  • Season the cream sauce with salt and pepper, then gently add the cod fillets. Cover the skillet and cook for 8-10 minutes, or until the fish flakes easily with a fork.
  • Fold the cooked potatoes into the sauce, ensuring they are coated thoroughly. Serve warm, garnished with fresh rosemary sprigs if desired.

Notes

For best results, choose fresh cod that smells briny. If you prefer a lighter version, substitute half-and-half for heavy cream. A splash of lemon juice just before serving adds brightness. This dish reheats beautifully, making leftovers just as delightful.
