Step-by-Step Instructions
- Sauté the Vegetables:
- Heat your largest heavy bottomed pot over medium heat. Add butter and allow it to melt completely but not brown. Add onion, celery and carrot, stirring frequently for about 5 minutes until vegetables soften and become translucent. The vegetables should not take on any color. When vegetables are soft, add minced garlic and cook for exactly one minute, stirring constantly to prevent garlic from burning which would impart bitterness.
- Create the Roux Base:
- Sprinkle flour evenly over the vegetable mixture, using a wooden spoon to incorporate completely. Cook for 2 to 3 minutes, stirring continuously. The mixture will become paste like and slightly golden. This cooking process eliminates the raw flour taste while creating the thickening foundation. Watch carefully as it can burn quickly.
- Develop the Broth:
- Pour in seafood stock gradually while whisking constantly to prevent lumps from forming. Add tomato paste, Old Bay seasoning, and cayenne if using. Bring mixture to a gentle simmer, then reduce heat to maintain a bare simmer for 10 minutes. This allows the flavors to meld and the broth to thicken slightly. Stir occasionally to prevent sticking.
- Refine the Texture:
- For restaurant quality smoothness, blend the bisque base. An immersion blender works perfectly, allowing you to control the texture. If using a standard blender, work in batches and be extremely careful with the hot liquid. Return the blended mixture to the pot over low heat.
- Enrich with Dairy:
- Pour in heavy cream and milk in a slow stream while stirring continuously. Add sherry if using. The alcohol cooks off leaving only complex flavor. Maintain a very gentle simmer for 5 minutes, never allowing the mixture to boil which could cause curdling.
- Incorporate Seafood:
- Gently fold in crab meat and raw shrimp. Cook for 5 to 7 minutes until shrimp turn completely pink and opaque. Be careful not to overcook the seafood which becomes tough quickly. The residual heat will continue cooking even after removed from heat.
- Final Seasoning:
- Taste carefully and adjust seasoning with salt and pepper. Remember that seafood naturally contains salt, so add conservatively. Ladle into warmed bowls and garnish with fresh herbs.

The Old Bay seasoning is my absolute favorite ingredient in this recipe. When I was growing up on the East Coast, we put it on everything from corn on the cob to french fries. That distinctive blend of herbs and spices instantly transports me back to family seafood feasts on summer evenings. I always keep two tins in my pantry just in case I run out.
Storing Your Leftover Bisque
This bisque will keep beautifully in the refrigerator for up to three days when stored in an airtight container. The flavors actually develop and improve overnight making it perfect for make ahead meals. When reheating, do so gently over low heat stirring frequently to prevent the dairy from separating. Never bring to a boil. If the bisque seems too thick after refrigeration, thin with a small amount of stock or milk until desired consistency is reached.
Smart Substitutions
If fresh seafood is unavailable or beyond your budget, this recipe adapts beautifully to alternatives. High quality frozen shrimp works perfectly when properly thawed overnight in the refrigerator. Canned lump crabmeat is a reasonable substitute for fresh, though rinse it gently first to remove any metallic taste. For a more economical version, increase the shrimp and reduce the crab. Those avoiding shellfish allergies can create a similar texture and experience using chunks of firm white fish like cod or halibut.
Elegant Serving Suggestions
Transform this bisque into a showstopping first course by serving in small portions in espresso cups for an elegant dinner party starter. For a complete meal, pair with a simple green salad dressed with lemon vinaigrette and crusty sourdough bread for dipping. A glass of unoaked Chardonnay or dry Riesling complements the creamy flavors perfectly. For special occasions, serve in hollowed out bread bowls or top each serving with an additional sautéed jumbo shrimp and a small drizzle of chili oil for dramatic presentation.
