The words base, foundation, and humble beginnings are all terms used to describe mirepoix. Pronounced meer-PWAHthis simple yet essential flavor base was named in the 18th century after the duke, Charles Pierre Gaston François de Lévis, or Duc de Mirepoix, a French general and diplomat. It is said that his chef de cuisine named this seasoning base after his patron – the Duke.

Considered key to many amazing recipes, mirepoix is found in many of my own personal favorites, including this Chicken Noodle SoupChicken Cacciatore, and Potato Soup.

So now that you know how important mirepoix is to cooking, let’s chat a little more about what it is, how to make your own, and mirepoix variations.

What is Mirepoix?

Mirepoix is a mix of aromatics, made from finely diced vegetables (the mix of vegetables will often vary by country and cuisine) that are cooked in butter or oil, low and slow, to sweeten the ingredients rather than caramelize them. These slow-cooked aromatic vegetables form the first layer of flavor in many recipes.

While a mirepoix may seem insignificant (or even pointless), it is one of the most essential steps in adding flavor to stews, soups, stocks, curries, stir-frys, etc.

The aromatics in mirepoix include onions, carrots, and celery, with a traditional ratio being 2:1:1, or two parts onion, one part carrot, and one part celery.

What are the aromatics in cooking?

Aromatics are a combination of vegetables, herbs, and (sometimes) meats that are heated in some fat (butter, oil, ghee, etc) at the beginning of cooking. The list of aromatics is long and varies depending on the dish being cooked. However, the most commonly used aromatics include onions, celery, carrots, ginger, and garlic.

Classic aromatic combinations:

  • Mirepoix (French): onion + carrot + celery with butter
  • Cajun Holy Trinity: onion + celery + green bell pepper with olive oil or butter
  • Soffritto (Italian): onions + carrots + celery with olive oil (often contains parsley)
  • Sofrito (Latin): onions + garlic + bell peppers + tomatoes with olive oil
  • Chinese: garlic + scallions + ginger with cooking oil
  • Indian: onion + garlic + chilies + ginger with ghee

How to make mirepoix

To make this mirepoix recipe, you’ll need two parts onion, one part carrot, and one part celery, plus olive oil.

  1. Prepare your vegetables. Trim the root ends and tips from the vegetables. Rinse and scrub the carrots and celery. Dry well. If desired, peel your carrots before chopping (tip: save your root ends and carrot peelings in a freezer-safe bag, then transfer to the freezer for homemade vegetable stock).
  2. Chop your vegetables. The size you choose to chop your onions, carrots, and celery will vary depending on the recipe being prepared. However, as a general guideline: for sautéed recipes, chop small (¼-inch to ½-inch); for soups and stews, medium size (½-inch to 1-inch); and for stock, broth, or blended soups, larger size (1-2 inches).
  3. Cook vegetables over medium-low heat. Add the olive oil to a large skillet set over medium-low heat. Add the onions, carrots, and celery, mixing well to coat. Cook, stirring often, for 10-12 minutes, or until softened and onions are translucent. Adjust the heat to prevent the vegetables from browning.

What do you cook first, mirepoix or meat?

Proper cooking order can be super confusing. What comes first, the meat or the mirepoix? Should I cook the mirepoix and meat separately or together? Unfortunately, there’s no hard-and-fast rule for either of these questions; however, it is customary to sear the meat first, remove it from the skillet to a clean plate, and use the fat from the meat to cook the onions, carrots, and celery.

Searing the meat first is especially important for stews, roasts, or curries that include beef, pork, or chicken thighs, as it adds extra flavor.

Recipes where you sear the meat first:

What size should I chop my mirepoix vegetables?

The overall size and shape of your vegetables will vary depending on the recipe being cooked. Most often, however, mirepoix vegetables are finely chopped.

As a general guideline:

  • For sauteed recipes- small (¼-inch to ½-inch)
  • For soups and stews- medium size (½-inch to 1-inch)
  • For stock, broth, or blended soups- large (1-2 inches)

Regardless of the size, it’s important to chop everything approximately the same size so that your vegetables cook evenly.

Can you freeze mirepoix?

Can you prepare a large batch of mirepoix ahead of time and freeze it? Yes, absolutely.

However, onions and celery do not freeze well. Once thawed, they are mushy and somewhat unappealing. For best results, I recommend using leftover thawed mirepoix in recipes that call for blending, such as Easy Acorn Squash Soup or Butternut Squash Soup.

What is the difference between mirepoix and the Holy Trinity?

The backbone of Cajun and Creole cooking, the Cajun Holy Trinity is a variant of the French mirepoix. Unlike mirepoix, the Holy Trinity is made with equal parts onion, celery, and green bell pepper. Variations may include aromatics such as garlic, parsley, or shallots.

What is the difference between mirepoix and Soffritto

The Italian version of mirepoix, soffritto, starts with the same foundation of finely chopped onions, carrots, and celery. Uncooked, this combination is called the “battuto”. Slowly cooked in olive oil, the battuto then becomes soffritto.

The primary difference between mirepoix and Italian soffritto is that soffritto is cooked in olive oil, not butter, and that it consists of minced vegetables rather than diced. Additionally, soffritto often includes additional ingredients such as garlic, parsley, fennel, and cured meat like pancetta or prosciutto.

Additional Mirepoix Variations

Aside from the Cajun Holy Trinity and Italian Soffritto, here are a few other variations popular throughout the world.

  1. Spanish Sofrito: Sofrito, meaning “gently fried”, is a mixture of onions, garlic, tomatoes, and (often) peppers or herbs cooked in olive oil. This flavorful tomato-based sauce is common in many recipes, including paella, stew, and pasta. There are several other versions of Sofrito, including recipes from all over Latin America and Portugal.
  2. German Suppengrün: Suppengrün, meaning “soup greens” in German, this version of mirepoix includes leeks, carrots, and celery root (celeriac). Variations may include parsley, thyme, or other root vegetables like onions and rutabaga. In general, in Germany, with its cold winter climate, the vegetables used are cold-climate roots and bulbs with longer shelf lives.
  3. French Pinçage: Very similar to traditional mirepoix, this variation comes with added tomato paste.
  4. Polish Włoszczyzna: Włoszczyzna, meaning “Italian stuff” in Polish, consists of carrots, parsnips or parsley root, celery root or celeriac, leeks, savoy or white cabbage leaves, and sometimes celery leaves and flat-leaf parsley. Traditionally, Włoszczyzna is uniformly chopped pieces of celery root, parsley root, carrots, and leeks, and is boiled.
