Heat olive oil in a large pot over medium-high heat. Add butter and melt it completely. Then, toss in the diced onion and sauté for about 3 minutes until softened and translucent. Add minced garlic and cook for 1 minute, stirring to avoid burning. These aromatics form the savory foundation of your bisque.
Sprinkle in the flour, stirring constantly to make a roux. Cook this mixture for about 2–3 minutes, allowing it to develop a slightly golden color. The roux is what gives your bisque its creamy, velvety texture.
Gradually pour in the seafood (or chicken) broth while whisking to prevent any lumps from forming. Once the liquid is smooth and incorporated, increase the heat slightly and bring everything to a boil.
Gently stir in the shrimp and crab meat. Simmer for 7–10 minutes, or until the shrimp are pink and cooked through. If your crab meat is pre-cooked, it will simply heat through without falling apart.
Pour in the heavy whipping cream and stir until the bisque turns a creamy, rich color. Add the paprika, salt, and pepper, then taste the bisque to adjust the seasoning as needed. The paprika not only adds flavor but also deepens the color of the broth. Cook for another 5 minutes.
Remove the pot from heat and garnish the bisque with freshly chopped parsley. This adds a pop of color and a hint of freshness that elevates the overall flavor.
Serve immediately while still warm, and don’t forget your favorite crusty bread or oyster crackers on the side—they’re perfect for dunking!
