🥗 Ingredients

The Fish

  • 4 pieces Cod Fillets (6-ounce portions, about 1-inch thick)
  • 1 teaspoon Kosher Salt (plus more to taste)
  • 1/2 teaspoon Black Pepper (freshly cracked)

Poaching Liquid & Aromatics

  • 1 cup Vegetable or Seafood Stock (low sodium preferred)
  • 1/2 cup Dry White Wine (such as Sauvignon Blanc or Pinot Grigio)
  • 1 Lemon (half sliced into rounds, half juiced)
  • 3 cloves Garlic (smashed)
  • 1 Shallot (thinly sliced)
  • 4 sprigs Fresh Dill (plus extra for garnish)
  • 2 sprigs Fresh Parsley (flat-leaf)
  • 1 Bay Leaf (dried)

The Finishing Sauce

  • 2 tablespoons Unsalted Butter (cold, cut into cubes)
  • 1 tablespoon Capers (drained)

👨‍🍳 Instructions

  1. 1

    Pat the cod fillets thoroughly dry with paper towels; this helps the seasoning stick and ensures a clean flavor.

  2. 2

    Season both sides of the fish evenly with kosher salt and freshly cracked black pepper.

  3. 3

    Pour the vegetable stock and white wine into the inner pot of the Instant Pot.

  4. 4

    Add the smashed garlic, sliced shallots, bay leaf, and the sprigs of dill and parsley to the liquid.

  5. 5

    Place the long-handled trivet (steam rack) into the pot, ensuring it sits above or partially submerged in the liquid.

  6. 6

    Lay the lemon slices across the trivet to create a citrus 'bed' for the fish.

  7. 7

    Carefully place the seasoned cod fillets on top of the lemon slices, ensuring they do not overlap.

  8. 8

    Secure the lid and set the steam vent to the 'Sealing' position.

  9. 9

    Select 'Pressure Cook' (or Manual) on High Pressure and set the timer for 2 minutes.

  10. 10

    Once the cooking cycle is complete, perform an immediate Quick Release of the pressure to prevent overcooking the delicate fish.

  11. 11

    Carefully open the lid and use a wide spatula to transfer the cod to a warm serving platter. Cover loosely with foil.

  12. 12

    Switch the Instant Pot to 'Sauté' mode. Remove the herb sprigs and bay leaf, then let the liquid boil for 3-4 minutes until reduced by half.

  13. 13

    Whisk in the cold butter cubes one at a time, followed by the lemon juice and capers, until the sauce is glossy and slightly thickened.

  14. 14

    Drizzle the warm lemon-butter sauce over the poached cod and garnish with fresh chopped dill before serving.

💡 Chef's Tips

If your cod fillets are very thin (less than 1 inch), set the pressure cook time to 1 minute to avoid a rubbery texture. Always use a 'Quick Release' for seafood; leaving it on 'Natural Release' will continue to cook the fish past its prime. For a non-alcoholic version, substitute the white wine with extra broth and a teaspoon of white wine vinegar. Ensure the butter is cold when whisking it into the sauce at the end; this creates a stable emulsion for a silky finish.

🍽️ Serving Suggestions

Serve alongside roasted fingerling potatoes to soak up the extra lemon-butter sauce. Pair with a crisp glass of Chablis or a sparkling mineral water with a twist of lime. A side of tender-crisp blanched asparagus or sautéed haricots verts complements the light nature of the dish. Place the fish over a bed of fluffy quinoa or jasmine rice for a wholesome, gluten-free meal.
