In general, your cod will be done when it reaches an internal temperature of 54Â°C (130Â°F), regardless of cooking method. Here are some times/temperatures that work for me: 1  Sous Vide: 10 minutes or more at 56Â°C, followed by a quick broiling/grilling/blow torch. 2  Baking (thick fillets): 15â20 minutes at 218Â°C (425Â°F).
