Filé gumbo is distinguished by the use of dried, finely ground sassafras leaves. Filé contributes an earthy, peppery flavor and gentle thickening while connecting Louisiana gumbo to Native American plant knowledge and regional family traditions.
Native American foodways provided some of the earliest foundations of Louisiana cuisine, contributing ingredients, environmental knowledge, preparation methods, and traditions still visible in Louisiana cooking today.
Louisiana cooking developed through centuries of cultural exchange among Native peoples, Africans, Europeans, Caribbean communities, Acadians, immigrants, and generations of Louisiana cooks.
