Lutefisk

About This Recipe

Lutefisk is made from air-dried stockfish (usually cod or ling) that has been soaked in cold water and then lye (lut) to rehydrate and transform it into a soft, gelatinous fillet. The lye treatment is then neutralised with multiple cold-water baths before cooking. It has been eaten in Norway since at least the Middle Ages and is deeply associated with the Christmas season. Opinions are fierce — devotees celebrate its silky texture and mild flavour, while sceptics find it challenging. Served with melted butter, mustard sauce, bacon, and boiled potatoes, it is a full Norwegian Christmas experience.

Ingredients

Serves 4

• 1 kgprepared lutefisk (lye-soaked, water-rinsed, ready to cook)
• 1 tspsalt
• 100 gunsalted butter, melted, to serve
• 100 gstreaky bacon, fried crispy, to serve
• 2 tbspDijon mustard, to serve
• 800 gboiled potatoes, to serve
• 200 ggarden peas, to serve

Instructions

1. 1

   Preheat oven

   Preheat your oven to 200°C (180°C fan / 390°F). Line a deep baking dish with aluminium foil.

2. 2

   Prepare the fish

   Place the prepared lutefisk skin-side down in the foil-lined dish. Sprinkle with salt. Do not add water — the fish contains enough moisture to steam itself.

3. 3

   Wrap and bake

   Fold the foil up over the fish to create a sealed parcel. Bake for 20–25 minutes until the fish is opaque and pulling apart in large, jiggly flakes.

4. 4

   Drain excess liquid

   Carefully open the parcel — there will be a pool of liquid. Tilt and drain it off before serving, as lutefisk releases a great deal of water during cooking.

5. 5

   Serve

   Plate the lutefisk and pour plenty of melted butter over it. Add crispy bacon, a spoonful of mustard, boiled potatoes, and peas alongside.

Variations

• •

  Some Norwegian families poach lutefisk gently in salted water rather than baking it.

• •

  A cream sauce with mustard and capers is used in some coastal regions instead of plain melted butter.

• •

  Vegetarian: swap the protein for roasted king oyster mushrooms, smoked tofu or cooked chickpeas — adjust seasoning slightly upward to compensate.

• •

  Spicier: add a finely chopped fresh chile or a teaspoon of crushed Aleppo/Urfa pepper to the aromatics for warm, layered heat instead of a single sharp hit.

Storage

Prepared lutefisk should be cooked and eaten fresh. Raw prepared lutefisk keeps refrigerated for 2–3 days before cooking.
