📝 About This Recipe

Originating from the fishing village of Findon, Scotland, Finnan Haddie is a cold-smoked haddock that offers a delicate balance of peat-smoke depth and sweet, flaky white fish. This classic preparation poaches the fish in a rich, onion-infused cream sauce, transforming a humble preserved staple into a luxurious, comforting masterpiece. It is the gold standard of Scottish coastal soul food, delivering a nostalgic warmth that is both sophisticated and deeply satisfying.

🥗 Ingredients

The Fish

  • 1.5 lbs Finnan Haddie (Smoked Haddock) (skin-on, bone-in preferred for flavor)
  • 2 cups Whole Milk (to cover the fish during poaching)
  • 2 pieces Bay Leaves (fresh or dried)
  • 6-8 pieces Black Peppercorns (whole)

The Sauce

  • 3 tablespoons Unsalted Butter (high-quality grass-fed if possible)
  • 1 medium Yellow Onion (very finely diced)
  • 3 tablespoons All-Purpose Flour (for the roux)
  • 1/2 cup Heavy Cream (for a luxurious finish)
  • 1 pinch Nutmeg (freshly grated)
  • 1/2 teaspoon Dry Mustard Powder (adds a subtle sharp bite)
  • to taste Kosher Salt (be cautious as the fish is naturally salty)

For Garnish and Service

  • 2 tablespoons Fresh Parsley (finely chopped)
  • 2 pieces Hard-Boiled Eggs (peeled and sliced into rounds)
  • 1 piece Lemon (cut into wedges)
  • 1 pinch Cayenne Pepper (for a dusting of color and heat)

👨‍🍳 Instructions

  1. 1

    Rinse the Finnan Haddie under cold water to remove any excess salt or surface impurities, then pat dry with paper towels.

  2. 2

    Place the fish in a large, shallow skillet or sauté pan. Pour the milk over the fish until it is nearly submerged. Add the bay leaves and peppercorns.

  3. 3

    Bring the milk to a very gentle simmer over medium heat. Do not let it reach a rolling boil, as this will toughen the delicate fish proteins.

  4. 4

    Poach the fish for 8-10 minutes. The fish is ready when it is opaque and just begins to flake easily with a fork.

  5. 5

    Carefully lift the fish out of the milk using a slotted spatula and transfer it to a plate. Cover loosely with foil to keep warm.

  6. 6

    Strain the poaching milk through a fine-mesh sieve into a clean jug, discarding the bay leaves and peppercorns. Reserve this liquid—it is liquid gold!

  7. 7

    In a clean saucepan, melt the butter over medium-low heat. Add the finely diced onions and cook for 5-6 minutes until soft and translucent, but not browned.

  8. 8

    Stir in the flour and mustard powder to create a roux. Cook for 2 minutes, stirring constantly to remove the raw flour taste.

  9. 9

    Slowly whisk in the reserved poaching milk, about half a cup at a time. Continue whisking until the sauce is smooth and thickened to the consistency of heavy cream.

  10. 10

    Stir in the heavy cream and a pinch of nutmeg. Taste the sauce before adding salt; the smoked fish often provides enough salinity on its own.

  11. 11

    While the sauce simmers on low, gently remove the skin and any remaining bones from the poached haddock. Break the fish into large, bite-sized flakes.

  12. 12

    Carefully fold the fish flakes into the cream sauce. Heat through for 1-2 minutes just to ensure everything is piping hot.

  13. 13

    Plate the Finnan Haddie in shallow bowls. Top with sliced hard-boiled eggs and a generous sprinkle of fresh parsley and a tiny dusting of cayenne.

💡 Chef's Tips

Always use 'undyed' Finnan Haddie if available; the bright yellow versions often use artificial coloring rather than traditional smoking methods. If the sauce becomes too thick, simply thin it with an extra splash of milk or a tablespoon of hot water. Be extremely gentle when folding the fish into the sauce to keep the flakes large and succulent rather than turning it into a paste. For an extra layer of flavor, you can sauté a small amount of leek along with the onions. Don't discard the skin and bones immediately; they can be used to start a wonderful seafood stock for later use.

🍽️ Serving Suggestions

Serve over a thick slice of toasted, buttered sourdough or traditional Scottish oatcakes. Pair with a side of creamy mashed potatoes (champ) or boiled new potatoes with plenty of dill. A crisp, acidic white wine like a Chablis or a dry Riesling cuts through the richness of the cream sauce beautifully. For a traditional breakfast experience, serve alongside grilled tomatoes and a pot of strong black tea. Accompany with steamed green peas or sautéed spinach for a pop of color and freshness.
