Étouffée refers to a group of dishes with Cajun origins which are typically served as a main course (unlike gumbo, which is considered a soup) and are made with one type of shellfish such as shrimp or crawfish that are smothered in a thick sauce.
The sauce is made with either a blond or brown roux, and the dish is almost always served over rice. The name étouffée is derived from the French word étouffer, meaning smothered, referring to the method of cooking.
