In a large pot, melt the butter over medium heat. Add the chopped onion and minced garlic, and sauté until softened and fragrant, about 3-4 minutes.
02 -
Sprinkle the flour over the onion and garlic mixture, stirring constantly to create a roux. Cook for 2-3 minutes, until the roux is golden brown and fragrant, which will help thicken the bisque and add depth of flavor.
03 -
Gradually whisk in the seafood or chicken broth, stirring constantly to prevent lumps from forming. Bring the mixture to a simmer and cook for 5-7 minutes, until slightly thickened.
04 -
Stir in the heavy cream and simmer for an additional 5 minutes, allowing the flavors to meld together and the bisque to reach a silky consistency.
05 -
Add the lump crabmeat and shrimp to the pot, and simmer gently until the shrimp are pink and cooked through, about 3-4 minutes. Be careful not to overcook the seafood to maintain its tender texture.
06 -
Season the bisque with salt and pepper to taste. If desired, use an immersion blender to partially puree the soup for a thicker consistency, being careful to leave some seafood pieces intact.

Ladle the seafood bisque into serving bowls, garnish with chopped fresh parsley, and serve hot with crusty bread on the side if desired.
