Beurre Manié

Also: kneaded butter, beurre manie

Equal parts raw butter and flour kneaded to a smooth paste and whisked into simmering sauces or stews to thicken them quickly without forming lumps.

/burr mahn-YAY/French — literally 'kneaded butter' (beurre = butter, manié = handled/kneaded); the technique appears in mid-nineteenth-century French cuisine manuals and is referenced in Escoffier's kitchen brigade practice.

Definition

Beurre manié is an uncooked thickener made by kneading together equal weights of softened unsalted butter and all-purpose flour until they form a homogeneous paste. Unlike a roux — in which the same two ingredients are cooked together — beurre manié is kept raw and added directly to a simmering liquid that is already at or near its final flavor. The butter acts as a dispersing agent: as the paste hits hot liquid, the fat melts and releases individual starch granules that are already coated in fat, preventing clumping. The granules then hydrate and swell, thickening the sauce in minutes. Because the starch is raw, the sauce must simmer for at least 2–3 minutes after the last addition to cook out the floury taste. Beurre manié is added in small pinches and whisked in gradually — this incremental approach lets the cook check the body of the sauce and stop precisely when the desired consistency is reached. It is an invaluable rescue tool for a sauce or braise that is too thin, and it finds regular use in classic fish stews, blanquettes, and fricassées.

In use

“The braise looked watery, so she pinched in small bits of beurre manié, whisking after each addition, until the cooking liquid turned glossy and just coated the back of a spoon.”

Notes

Ratio

The classic ratio is 1:1 by weight — typically 30 g butter to 30 g flour, which is enough to thicken roughly 500 ml of liquid to a medium-body nappant consistency. For a lighter result, use slightly less flour; for a thicker sauce, increase the flour fraction modestly, but never exceed a 1:1.5 butter-to-flour ratio or the paste becomes dry and harder to disperse.

Raw flour taste

Because the starch is raw at the moment of addition, the sauce must be held at a gentle simmer for at least 2–3 minutes after the final addition. Tasting for raw starch is the best check: a faint chalky or paste-like aftertaste indicates more cooking time is needed.

Roux vs. beurre manié

Both use butter and flour in similar proportions, but roux is cooked before the liquid is added — which eliminates raw starch flavor and creates a more stable thickened sauce from the start. Beurre manié is a finishing and rescue tool added to a liquid already at volume; it introduces richness along with the thickening. A roux-based sauce tends to be more neutral-tasting and longer-stable; a beurre-manié-thickened sauce has a fresher butter character.
