This classic Louisiana courtbouillon transforms simple redfish into a deeply flavorful feast. The dish relies on a dark roux made from butter and flour, which provides a nutty backbone to the broth. Aromatic vegetables like onions, celery, and bell peppers soften in the roux before being joined by canned tomatoes and a blend of dried herbs including oregano, marjoram, and thyme. The redfish slices are gently poached in this spiced liquid until just flaky, absorbing the savory, slightly spicy essence of the sauce. Finished with a splash of white wine and served over hot rice, it offers a comforting, rustic dining experience perfect for a cozy weeknight dinner or a casual weekend gathering. The balance of herbal notes and gentle heat makes it both satisfying and aromatic.
