Lobster Bisque Recipe

Cook and pick lobster

If starting with live lobsters: bring 4 L water to a rolling boil with 2 tablespoons kosher salt. Add lobsters headfirst, cover, and boil 8–10 minutes until shells are bright red and meat registers 135°F internally. Remove lobsters to an ice bath to stop cooking. When cool enough to handle, crack shells, remove tail and claws, and pick out all meat. Reserve 1 cup chopped lobster meat for finishing and refrigerate. Keep shells (cracked and roughly broken) for stock. If using pre-cooked lobster meat and additional shells, skip the boiling step and proceed with shells for stock.

Rinse shells

Rinse the shells briefly to remove any debris or bits of digestive tract. Pat shells dry.

In a large heavy-bottomed pot over medium heat, melt 1 tbs butter with 1 tbs vegetable oil. Add the onion, carrot, and celery and sweat gently for 6–8 minutes until softened but not browned. Add the minced garlic and cook 30–45 seconds until fragrant.

Stir in the tomato paste and cook 2–3 minutes, stirring frequently, until the paste darkens slightly. Add the lobster shells and toss to coat with the mirepoix and tomato paste. Cook 3–4 minutes to begin toasting the shells, browning them lightly for deeper flavor.

Deglaze the pot with 1 cup dry sherry or white wine, scraping up any browned bits from the bottom; let the alcohol reduce by half (about 2–3 minutes).

Add 4 cups fish or seafood stock (and up to 2 cups cold water if needed to cover shells), the bay leaf, peppercorns, and thyme. Bring to a gentle simmer, then reduce heat to low and simmer, partially covered, for 30–40 minutes to extract flavor from the shells and aromatics. Do not boil vigorously.

After simmering, remove from heat and strain the stock through a fine-mesh sieve or chinois into a clean pot or bowl, pressing on solids to extract as much liquid as possible. Discard solids. Skim and discard excess fat from the strained stock if desired.

Return strained stock to a clean pot and bring to a gentle simmer over medium-low heat. Stir in 1 cup whole milk and 1 cup heavy cream. If you prefer a thicker bisque, make a roux: melt 2 tbs cold butter in a small skillet, whisk in 2 tbs all-purpose flour and cook 1–2 minutes until lightly golden, then whisk the roux into the simmering stock. Alternatively, whisk a cornstarch slurry of 2 tbs cornstarch with 2 tbs cold water and stir into the simmering liquid until slightly thickened.

Season the bisque with 1 tsp salt, 1 tsp paprika, and adjust with freshly ground black pepper. Simmer gently for 6–8 minutes to meld flavors, stirring occasionally. Taste and adjust seasoning. If the bisque tastes too strong or salty, add up to 1/2 cup additional milk or water to balance.

For a smoother, restaurant-style bisque, use an immersion blender to purée the soup until silky, or transfer in batches to a blender and purée until very smooth. Return to the pot and re-warm gently.

Stir in 2 tablespoons cold diced butter one piece at a time (monter au beurre) to finish the sauce, followed by 2 tablespoons sherry (optional) and 1 teaspoon fresh lemon juice to brighten the flavors.

Add the reserved chopped lobster meat to the warmed bisque and heat gently for 1–2 minutes until just warmed through. Do not boil, or lobster will become tough.

Ladle bisque into warmed bowls, garnish with chopped chives or parsley, and finish with a grind of black pepper and additional sea salt to taste. Serve immediately with crusty bread or a buttered toast point.

If you used a cornstarch slurry instead of roux and the bisque is thinner than desired, combine 1 teaspoon cornstarch with 1 teaspoon cold water and whisk into hot soup, simmering 1–2 minutes until thickened. If using roux, adjust by whisking in a little more warm cream or stock to reach desired consistency.
