Today we’re going to talk about the single-most important flavor factor for a lot of different dishes: mirepoix. (Pronounced meer-PWAH.) Yes, this is a very fancy-pants sounding word*, 😂 but what really matters is that knowing how to make a mirepoix recipe can SERIOUSLY up your game while cooking.
A mirepoix is a simple mixture of chopped onions, celery, and carrots that you cook gently on the stove until the vegetables develop complex flavors, usually until they are browned. You then use these cooked vegetables as the base for the rest of your dish (such as stocks, soups, and sauces). You don’t really need a mirepoix recipe once you’ve made it a couple of times, but it’s handy to have a recipe the first time so you can get the hang of how to make one.
A mirepoix recipe is really simple, but there’s a catch. Proper browning is SUPER important for maximum flavor. A well-done mirepoix recipe can bring all sorts of flavors to the table: sweetness, nuttiness, and that savory “roundness” we know as umami. (Oh yay, another pretentious-sounding word!)
There’s a catch to this catch, though… and it’s this: if you’re making a white soup where the white color is really important (like clam chowder) then browning your vegetables will turn your soup beige. So if you’re making a white soup and you want it to stay looking bright white, don’t brown your vegetables.
Lots of dishes use a mirepoix recipe, so if you want to become a better cook, it’s worth learning how to do this right. The basic ratio for a standard mirepoix recipe is:
- 2 parts chopped onion
- 1 part chopped carrot
- 1 part chopped celery
So if you’re making one cup of mirepoix, 1/2 cup is onion, 1/4 cup is carrots, and the remaining 1/4 cup is celery. These vegetables should be chopped to relatively small bits, anywhere from 1/2- to 1-inch pieces. Ideally all of the chopped vegetables bits are about the same size so they cook at the same rate and look nice when they’re done.
This mirepoix recipe is a simple mixture of chopped onions, celery, and carrots that you cook gently on the stove until the vegetables develop complex flavors, usually until they are browned. You then use these cooked vegetables as the base for the rest of your dish (such as stocks, soups, and sauces).
- 1 medium onion
- 1 whole carrot
- 1 rib of celery
- 2 tablespoons cooking oil
Peel the onion. Wash, dry, and trim the ends off the carrot and celery. (No need to peel them.)
- Using a sharp 8-inch kitchen knife, cut each vegetable into 1/2-inch cubes. Here’s a video on how to chop an onion so that all the pieces are the same size.
- Pour the oil into your pan and set it over medium heat. As soon as the oil begins to shimmer, add the vegetables to the pan and stir well. Do not let the oil smoke! If it starts to smoke, throw out the oil, wash the pan, and start over. Burnt cooking oil tastes really bad.
- Continue to cook the vegetables, stirring every few minutes, until they are well browned (but don’t let them burn). Don’t be afraid to let the vegetables sit and brown before stirring. This is the process of caramelization that creates so much flavor. Part of learning to cook is knowing where the line is between browning and burning, and mirepoix is a PERFECT simple dish to learn this lesson.
- Once the vegetables are well-browned and fragrant -- stick your face into the steam and you’ll notice they’ll smell very sweet and a little nutty -- they’re done. This is where you add them to whatever dish that calls for them.
- Stainless steel pan (see notes below)
- Wooden spoon
A few notes:
- Sometimes a mirepoix can be chopped into large pieces, such as for making stock, and other times it’s chopped into small pieces. It all depends on the dish and how long it cooks. General rule: the longer it cooks, the larger the pieces can be.
- You may find some mirepoix recipes where the mirepoix is not cooked beforehand at all, though I usually brown them anyways, because that’s the whole purpose!
- Some dishes may call for more ingredients to be added to the mirepoix recipe. This is totally normal. 🙃
- If you’re making an all-white dish, like a white sauce, you might want to make a white mirepoix. In this case, you would just gently cook the vegetables until they’re soft, but not brown, so they do not turn your finished dish brown.
- When you make a white mirepoix, sometimes you’ll be told to leave out the carrots. Instead of carrots, you can use chopped parsnips and white mushrooms to add more flavor.
- It’s very hard to make a proper mirepoix in a nonstick pan. Nonstick pans are made to prevent browning, which is the very things you want your vegetables to do! If you’ve got a stainless steel pan, preferably one with a heavy bottom, use that. If all you have is nonstick, then just use that and BE A REBEL. 😎 This is cooking, not brain surgery — no one will die if you make do with what you’ve got. 😘
Now that you know how to make a mirepoix recipe, here are a few recipes you might want to try so you can practice:
- Easy vegetarian mirepoix soup
- Split pea soup with chicken
- Better-than-your-grandma’s chicken group
- Vegan gumbo from Disneyland <– you’ll notice this mirepoix has no carrots
Mirepoix in other places
Mirepoix is basically the concept of using cooked vegetables as a flavor base for a larger dish. There are different kinds of flavor bases used in different cultures, and every country calls it something different. The mirepoix I’ve outlined above is used in most French cooking, and by proxy a lot of western cooking as well.
Here are a few other flavor bases you might see in different cooking cultures, and these can change from region to region within a country:
- Creole: onion, celery, green bell peppers (also known as “the holy trinity”)
- Italian: onion, tomato, garlic, basil
- Spanish: tomato, onion, garlic
- German: leek, carrot, celery root
- Chinese: green onions, ginger, garlic
- Thai: garlic, lime, lemongrass, chili paste
That’s it! Well done. :)
* If you guessed that this pretentious-sounding word is French, you’d be right. It’s named after an area in southwest France, or rather an 18th century duke of the region. /nerdglasses
