Louisiana Fish Coubion (Courtbouillon)
Health starts in the kitchen.If you grew up in South Louisiana like I did, you probably knew this dish simply as coubion. Some spell it courtbouillon — the original French term meaning “short broth.” Either way, it’s a deeply comforting Creole tomato-based fish stew that tastes like home.Traditionally served over rice, this version keeps all the bold Cajun flavor but lightens it up. No roux. No oil. No flour. Just rich tomato broth, fresh herbs, and tender white fish gently poached until flaky and perfect.You can make it in 30 minutes for a weeknight dinner — or let it simmer longer for Sunday-level depth.Both versions work beautifully for a low-carb lifestyle.
