Beurre Blanc with cod

Bake the cod on low heat so it retains its moisture and does not become dry. Serve the fish with Beurre Blanc with lemon, roe and chives and new potatoes.

Recipe for beurre blanc

Good side dishes are mashed potatoes and baked celeriac.
A Muscadet sur lie or a Chablis goes well with this.

Baked cod with Beurre Blanc is the dish that proves Norwegian fish deserves French-inspired treatment. The cod is baked at a low heat, around 60 to 65°C, so it stays silky and juicy all the way through. Paired with the classic French butter sauce with lemon, roe and chives, you get a dish with real elegance.

It is a dish that teaches you two valuable techniques at once: low temperature baking and Beurre Blanc. Master both and you have a solid foundation for many impressive fish dishes to come.

The key to perfect cod is a low oven temperature and not overcooking it. At 48 to 50° in the centre it is at its juiciest and melts in your mouth.

Tips and variations

  • Bake the cod to a core temperature of 60 to 65°C for optimal juiciness. Use a meat thermometer for precise control.
  • Pat the fish fillet dry and season with salt 20 to 30 minutes before baking. It draws out moisture and gives a cleaner flavour.
  • The Beurre Blanc reduction can be made in advance; whisk in the cold butter just before serving.
  • Fish roe and chives are added to the Beurre Blanc just before serving for freshness and visual appeal.
  • New potatoes boiled with dill are the classic and excellent accompaniment to this dish.

🍷 Wine tips

Muscadet sur lie: Beurre Blanc with cod, pure and delicate fish with a silky butter sauce, is perfectly matched by Muscadet sur lie from the Loire. Mineral, dry and crisp. Chablis is a fuller-bodied alternative that works equally well.

Notes

Tips: The butter emulsifies best at low constant heat, do not let the sauce boil. Add ice-cold butter cubes a little at a time and stir constantly in circles.

Storage: Beurre blanc is made just before serving, the sauce splits easily and cannot be reheated.

FAQ: Cod can be replaced with halibut, pollock, monkfish or any firm white fish. Beurre blanc works with most seafood.

Frequently asked questions about beurre blanc with cod

Can I use other fish?

Yes, halibut, pollock, haddock or salmon are all good candidates for low temperature baking with Beurre Blanc. Halibut is especially good: it is tender and naturally suits the richness of the butter sauce.

What is roe?

Roe is fish eggs, in this case preferably capelin roe or cod roe. It adds a salty, briny flavour and a slightly crunchy texture that contrasts beautifully with the soft fish and the silky sauce.

What do I do if the Beurre Blanc splits?

Take the sauce off the heat and quickly whisk in a teaspoon of ice cold water or a small knob of cold butter. Temperature is the key: the sauce must never boil, just be kept warm at around 50 to 60°C.

How do I prevent the cod from drying out?

Bake it at a low temperature and take it out when the core reaches 48 to 50°C. If you pan-fry it instead: Cod cooks quickly, so sear on high heat for 2 to 3 minutes per side. The core temperature should reach 55-58 degrees C.

Can I use frozen cod?

Yes, but thaw completely in the refrigerator and pat thoroughly dry before cooking to avoid steaming instead of searing.

What can I serve alongside?

Boiled potatoes, spinach, or asparagus work beautifully. The beurre blanc is rich, so simple sides are best.
