Creating Creamy Crab and Shrimp Bisque is straightforward if you follow these steps:

1. Sauté Vegetables: In a large pot, heat olive oil and butter over medium heat. Add the chopped onion and garlic, cooking until soft and translucent, about 5 minutes.
2. Add Seafood Stock: Pour in the seafood stock and bring to a simmer, allowing the flavors to meld.
3. Season the Broth: Stir in the Old Bay seasoning and paprika. Add salt and pepper to taste.
4. Incorporate Shrimp: Add the shrimp to the pot and cook for about 5 minutes, or until they turn pink and opaque.
5. Add Crab Meat: Gently fold in the crab meat, taking care not to break it apart too much.
6. Blend for Creaminess: Use an immersion blender to blend the bisque until it reaches your desired consistency. If you prefer a chunkier texture, blend just a portion.
7. Stir in Cream: Lower the heat and stir in the heavy cream. Allow it to heat through for about 5 minutes, but do not boil.
8. Taste and Adjust: Taste the bisque and adjust seasoning if necessary.
9. Serve Hot: Ladle the bisque into bowls and garnish with fresh parsley and a squeeze of lemon.
