Crab Bisque

This elegant crab bisque is a sophisticated dairy-free starter that celebrates the deep, savoury flavours of the coast. By simmering whole crushed crabs with aromatic vegetables, white wine and a splash of brandy, you create a foundation of wonderful depth and character. Unlike traditional recipes that rely on heavy cream, this version uses blended long-grain rice to achieve a silky, luxurious texture that remains light and refined on the palate.

Ideal for a dinner party or a special weekend treat, this homemade seafood soup is both comforting and impressive. The addition of fresh lemon juice and tarragon provides a bright finish that perfectly balances the rich shellfish broth. Serve it topped with sweet lump crabmeat for a high-protein, heart-healthy dish that brings a touch of coastal fine dining to your kitchen table.

How to make Crab Bisque

If using live crabs, add to pot of boiling water using tongs. Cover pot and cook over high heat until crab shells are red, 5 to 6 minutes. Drain crabs in a colander.

Put crabs (cooked or frozen uncooked) into a large metal roasting pan. Cover with a clean kitchen towel and pound shells with meat pounder to crush (including claws).

Heat butter and oil in same pot over medium-high heat until foam subsides, then cook onion, carrot, celery, and garlic with bay leaf, thyme, clove, peppercorns, and 1/2 teaspoons salt, stirring occasionally, until softened, about 5 minutes. Add Cognac, wine, and crushed crabs and bring to a boil. Add broth and water and return to a boil. Skim foam, then simmer, covered, stirring and skimming occasionally, 1 hour.

Put colander in a large bowl, then drain crab broth, reserving solids for crab butter (if making). Transfer broth to a medium saucepan.

Ladle out 475ml broth and transfer to a 1-quart saucepan. Add rice and simmer, covered, until very tender, 15 to 20 minutes (not all of liquid will be absorbed).

Blend together rice with cooking liquid and 240ml more crab broth in a blender until smooth (use caution when blending hot liquids), then add to remaining broth in medium saucepan.

Just before serving, reheat bisque over medium heat until hot, then stir in tarragon, lemon juice, cayenne, and 1/8 teaspoons pepper.

Ladle bisque into bowls and spoon a little crabmeat into centre, then drizzle with some of crab butter (if making).
