What is Mirepoix?

Mirepoix is the unsung hero of countless comforting meals. This simple combination of diced onions, carrots, and celery forms the flavorful backbone of French cuisine. Often sautéed slowly in olive oil or butter, mirepoix is used to infuse soups, stews, stocks, and sauces with rich, savory depth.

The traditional French mirepoix recipe calls for a 2:1:1 ratio two parts onions to one part each of carrots and celery. While it seems humble, this trio unlocks incredible complexity in cooking. You’ll spot variations across cultures too, like Italy’s soffritto or the Cajun Holy Trinity that swaps carrots for bell peppers.
