Crawfish Etouffee

Heat oil in a large saucepan over medium heat; add onions and garlic and cook, stirring frequently, until the onions start to become translucent, 8 to 10 minutes. Add thyme and flour and cook, stirring, for 1 minute. Stir in broth, Cajun seasoning, paprika and hot sauce. Cook until the mixture thickens slightly, 2 to 3 minutes. Stir in crawfish (or shrimp). Bring to a gentle simmer, cover and cook, stirring occasionally, for 10 minutes. Remove from the heat and stir in scallions and parsley.
