In a pan over medium high heat melt the butter
Add celery, carrots and onions to the pan and sauté until the veggies are tender
Once the veggies are tender add the creole seasoning, the tomato paste and the flour and stir
Add the broth and bring to a simmer
Once the broth has thickened slightly use an immersion blender to blend the broth and veggies smooth.
Add the diced shrimp and simmer until the shrimp are cooked
If you would like a smooth bisque, you can blend the shrimp once it is cooked through
Remove from the heat and add the half and half
Add the sherry wine and the parsley to the bisque.
Enjoy!
