What Is Mirepoix?

Mirepoix is a recipe base made from diced vegetables that are cooked slowly (usually with some sort of fat, like butter or oil) to sweeten and deepen the flavors of a dish. The mix is cooked over very low heat, as the intention is to intensify the vegetables' flavor — not to caramelize them.
French mirepoix is made with celery, onions, and carrots. The traditional ratio is 1:2:1 (one part celery, two parts onions, and one part carrots). The trio serves as the foundation for many Western soups, stews, and sauces.

What Is Pincage?
Pincage is simply mirepoix with tomato paste. The mixture is cooked until the tomato paste turns brown, and becomes more savory than sweet. You'll often find pincage in vegetarian recipes, as it adds a bit of umami flavor to meatless dishes.

Mirepoix History

Though the use of carrots, onions, and celery as a flavor base is likely more than a few hundred years old, mirepoix is likely named after the 17th-century Duke of Mirepoix (a town in Southwestern France), whose cook was known for popularizing the mixture. The duke was "an incompetent and mediocre individual," Pierre Larousse wrote in The Oxford Companion to Food in the late 19th century, "who owed his vast fortune to the affection Louis XV felt toward his wife and who had but one claim to fame: he gave his name to a sauce made of all kinds of meat and a variety of seasonings."
Mirepoix vs. Cajun Holy Trinity

Unlike French mirepoix, which uses a 1:2:1 ratio of carrots to onions to celery, the Cajun Holy Trinity is made from equal parts celery, onions, and bell peppers.
Cajun cuisine is famously inspired by French methods and flavors, as French Catholics and Acadians (or "Cajuns," as pronounced by English-speaking Louisianians) settled in New Orleans in the early 18th century. The settlers quickly realized that, while the Louisiana ground wasn't suitable for growing carrots, it was ideal for growing bell peppers.
Can You Freeze Mirepoix?

Yes, you can freeze uncooked mirepoix. If you use the trio of vegetables frequently, it might be a smart time-saving move. Just follow a series of simple steps:
- Dice your carrots, onions, and celery (remember, the ratio is 1:2:1).
- Lay the diced vegetables flat on a lined baking sheet. Cover with foil or plastic wrap. Freeze overnight.
- The next day, transfer the frozen veggies to freezer-safe bags labeled with the date. Freeze up to six months.
Thaw the mirepoix overnight in the fridge or cook from frozen with olive oil or butter.
