Creating Creamy Crab and Shrimp Seafood Bisque is simple when you follow these clear steps:

1. Sauté Vegetables: In a large pot, melt the butter over medium heat. Add the chopped onion, garlic, celery, and carrots. Sauté for about 5-7 minutes until softened.
2. Add Spices: Stir in the thyme, paprika, salt, and pepper. Cook for an additional minute to release the flavors.
3. Pour in Stock: Add the seafood stock to the pot and bring to a boil. Reduce the heat and let it simmer for 10 minutes.
4. Add Seafood: Gently stir in the crab meat and shrimp. Cook for 5-7 minutes until the shrimp are pink and cooked through.
5. Incorporate Cream: Pour in the heavy cream and stir to combine. Allow the bisque to heat gently for another 5 minutes.
6. Finish with Lemon: Add lemon juice to brighten the flavors. Taste and adjust seasoning if necessary.
7. Blend for Smoothness: For a smoother texture, use an immersion blender to puree the bisque slightly, leaving some chunks of seafood for texture.
8. Garnish: Ladle the bisque into bowls and garnish with fresh parsley.

These steps will lead you to create a bisque that is not only delicious but also visually appealing.
