Direction

1. Melt butter in a large, heavy saucepan over medium heat until foamy, about 2 minutes. Stir in flour to foamy butter, whisking quickly to make sure there are no lumps. Continue stirring until roux turns a dark, reddish brown, about 5 minutes.
2. Stir in onion, celery, bell peppers, and garlic. Cook and stir until the vegetables have begun to be tender, about 5 minutes.
3. Stir in Cajun seasoning and chicken broth and bring to a boil. Add sliced smoked sausage and season with red pepper flakes, black pepper, and salt to taste. Cover, reduce heat to low, and simmer about 10 minutes.
4. Remove cover, increase heat to medium high, and return to a boil. Add shrimp and cream, and cookuntil shrimp turn pink and are curled into a C-shape, about 3 minutes.
5. Serve warm over cooked spaghetti. Garnish with fresh parsley and lemon slices, if desired.
