Creating the Creamy Crab and Shrimp Seafood Bisque is a straightforward process if you follow these steps:

1. Sauté Vegetables: In a large pot, heat the olive oil and butter over medium heat. Add the diced onion, celery, and carrot. Sauté for 5-7 minutes until softened.
2. Add Garlic: Stir in the minced garlic and cook for another 1-2 minutes until fragrant.
3. Add Stock: Pour in the seafood stock or vegetable broth. Bring the mixture to a simmer.
4. Season: Stir in the Old Bay seasoning, paprika, salt, and pepper. Let it simmer for about 10 minutes to allow the flavors to meld.
5. Add Seafood: Gently add the crab meat and shrimp to the pot. Cook for an additional 5-7 minutes until the shrimp are pink and cooked through.
6. Incorporate Cream: Reduce the heat to low and slowly stir in the heavy cream. Allow it to heat through but do not let it boil.
7. Blend (Optional): For a smoother bisque, use an immersion blender to blend a portion of the soup for a creamier texture while leaving some chunks for added heartiness.
8. Adjust Seasoning: Taste and adjust the seasoning if necessary, adding more salt or pepper as desired.
9. Serve: Remove from heat and let the bisque sit for a few minutes before serving. This resting time helps enhance the flavors.
