North America

Sassafras / Filé

Sassafras albidum.

Leaf (ground into filé powder); root bark (historically used for tea and root beer flavoring, though now restricted – see safety note).

Part Used

Dried, ground leaf (filé powder).

Form

Local / Regional Names

Filé powder (Louisiana Creole/Cajun French, from the ground dried leaf specifically); sassafras more broadly refers to the tree and its other parts.

Countries / Cuisines

United States (Louisiana, for filé powder specifically, learned from Choctaw and other Indigenous peoples; the tree's broader range covers much of the eastern United States).

Flavor & Aroma

Earthy, slightly citrusy-root beer-adjacent, with a notable thickening/mucilaginous quality when the leaf powder is added to a hot liquid.

Culinary Uses

A traditional Louisiana Creole thickener and flavoring for gumbo, used as an alternative or complement to okra.

Classic Dishes

Gumbo filé (a specific gumbo style thickened with filé powder rather than or alongside okra).

Pairings

Okra, rice, Cajun/Creole spice bases.

Timing

Stir filé powder into a gumbo off the heat, at the very end of cooking or at the table – boiling filé powder makes it stringy and unpleasant, a critical technique point.

Storage

Ground powder keeps about a year sealed and dark before losing potency.

Substitutions

Okra as the traditional thickening alternative, understanding the flavor and texture differ.

Cultural / History Notes

IMPORTANT SAFETY NOTE: the tree's root bark, once used for traditional sassafras tea and original root beer flavouring, contains safrole, a compound restricted by the FDA for use in commercial food products due to carcinogenicity concerns in animal studies – filé powder made from the leaf is a separate, still-permitted product, so it is the leaf (filé) that is used in modern cooking, not the root bark.
