Creating New Orleans Shrimp and Corn Bisque can be broken down into manageable steps:

1. Prepare the Ingredients: Chop the onion, bell pepper, and garlic. Peel and devein the shrimp if not already done.
2. Sauté Vegetables: In a large pot, heat the olive oil and butter over medium heat. Add the chopped onion and bell pepper. Sauté until they soften, about 5 minutes.
3. Add Garlic: Stir in the minced garlic and cook for an additional minute, ensuring it doesn’t burn.
4. Incorporate Stock: Pour in the seafood stock. Add the dried thyme, cayenne pepper, and Worcestershire sauce. Bring to a simmer.
5. Add Corn: Stir in the corn kernels and let the mixture cook for about 10 minutes to allow flavors to meld.
6. Add Shrimp: Gently add the peeled shrimp to the mixture. Cook until they turn pink and opaque, about 3-5 minutes.
7. Blend for Creaminess: If you prefer a smoother texture, carefully blend the bisque using an immersion blender until desired consistency is achieved. For chunky bisque, skip this step.
8. Stir in Cream: Lower the heat and slowly add the heavy cream, stirring until well incorporated. Heat through but do not boil.
9. Season: Taste and adjust seasoning with salt and pepper as needed.
10. Serve: Garnish with freshly chopped parsley before serving.

These steps will guide you in creating this wonderful bisque that perfectly showcases the rich flavors of New Orleans cuisine.
