Crab bisque is a classic soup that brings the flavors of the ocean to your table. This version starts with a aromatic base of shallots, carrot, and garlic, cooked in butter and enriched with a roux.

Seafood stock and a blend of spices create a deep, savory broth, while heavy cream and lemon juice add richness and brightness. The soup is finished with tender lump crab meat, then topped with extra jumbo lump crab and fresh chives for a truly indulgent bowl.

Ingredients

Why this recipe works

The method starts by building a roux with butter and flour, which thickens the bisque and gives it a silky texture.

Cooking the flour briefly removes any raw taste and helps the soup hold its body without being heavy. Sautéing the aromatics first releases their natural sweetness and creates a flavorful foundation.

Blending the soup with an immersion blender ensures a perfectly smooth, velvety consistency.

Adding the crab meat at the end and heating it gently prevents the delicate chunks from breaking apart, so every spoonful has satisfying pieces of crab. The lemon juice brightens the flavors and balances the richness of the cream.

Notes and substitutions

For the best flavor, use high-quality lump crab meat. Fresh or pasteurized crab meat works well; avoid canned crab that may be overly salty or mushy. Jumbo lump crab is ideal for the topping because it has large, beautiful pieces that make the dish look impressive.

Seafood stock is available in most supermarkets, or you can use clam juice or fish stock. If you prefer a thicker bisque, you can blend in a little cooked rice or potato, but this recipe keeps it classic. The garlic herb butter crostini can be made ahead and stored in an airtight container for up to 2 days.
