Creating the Creamy Crab and Shrimp Seafood Bisque is straightforward. Follow these step-by-step instructions for the best results:

1. Sauté Aromatics: In a large pot, heat the butter and olive oil over medium heat. Add the chopped onion and minced garlic. Sauté until they become translucent.

2. Add Seafood Stock: Pour in the seafood stock and bring it to a gentle simmer.

3. Season the Broth: Stir in the paprika and Old Bay seasoning, and season with salt and pepper to taste.

4. Incorporate Crab and Shrimp: Add the crab meat and shrimp to the pot. Let them cook for about 5-8 minutes or until the shrimp turns pink and opaque.

5. Blend for Smooth Texture (optional): For a smoother bisque, use an immersion blender to puree the soup to your desired level of creaminess.

6. Stir in Cream: Lower the heat and pour in the heavy cream. Stir until well combined. Heat through but do not bring to a boil.

7. Final Seasoning: Taste and adjust the seasonings if necessary.

8. Serve: Remove from heat and ladle the bisque into bowls. Garnish with chopped parsley.

9. Enjoy: Serve immediately. Optional: Provide lemon wedges on the side for added brightness.
