Poached Lobster Recipe

This poached lobster recipe pairs tender, perfectly cooked lobster with a rich gastrique sauce made from caramelized sugar, apple cider vinegar, butter, and fresh lime zest. Featured on Fish the Dish, hosted by Spencer Watts, this dish delivers a balance of sweet, tangy, and buttery flavours for an elegant, restaurant-quality seafood experience at home.

The Inspiration

Poached lobster is a timeless technique that highlights the natural sweetness and delicate texture of this luxurious seafood. By gently cooking the lobster in salted water and finishing it in a gastrique sauce, this recipe builds layers of flavor while maintaining the integrity of the meat.

A gastrique—a classic French sauce made by caramelizing sugar and deglazing with vinegar—adds a bold contrast to the richness of lobster. The sweet and tangy profile cuts through the buttery notes, creating a perfectly balanced dish.

On Fish the Dish, Spencer Watts often showcases how classic culinary techniques can be simplified for home cooks without losing their elegance. This recipe reflects that philosophy, combining refined flavor with approachable execution.

The addition of lime zest at the end brings brightness and freshness, lifting the entire dish and enhancing the natural sweetness of the lobster.

Ingredients

• 2 whole live lobsters (1-1.25 pounds each or 455-565 grams each)
• Salt

Method

• Bring salted water to a boil in large pot.

Serving Suggestions

This poached lobster recipe is ideal for special occasions, romantic dinners, or elevated entertaining where you want to impress with minimal yet refined ingredients. The sweet and tangy gastrique sauce pairs beautifully with light, fresh sides that balance the richness of the lobster.

Serve it alongside a crisp cucumber mint salad, which provides cooling freshness and a clean contrast to the bold sauce. Other great accompaniments include steamed asparagus, lightly dressed greens, or simple buttered new potatoes that soak up the flavorful gastrique.

For presentation, arrange the lobster pieces neatly on a plate and drizzle the sauce generously over top. Garnish with extra citrus zest or fresh herbs for a bright, elegant finish.

In terms of beverages, this dish pairs exceptionally well with sparkling wine, Champagne, or a crisp white wine like Chablis or Sauvignon Blanc. The acidity in these drinks complements the gastrique while enhancing the natural sweetness of the lobster. For non-alcoholic options, sparkling water with citrus or a light herbal infusion works beautifully.
