How to Make Mirepoix (and Freeze It)

Learn how to make mirepoix—which is a mix of onion, celery, and carrot typically used to start soups and sauces—and store it in the fridge or freezer when you have time, then grab it for easier cooking in the moment.

How to Make Mirepoix

Prepping veggies for soups and sauces ahead of time has been a total game-changer in my kitchen. I love using lots of produce in my recipes, but it’s often a challenge to peel and chop it when things are busy and kids are underfoot. With this technique, you can batch-prep onions, carrots, and celery and store it for future meals so it’s ready to grab and go.

You can store these vegetables in the refrigerator or in the freezer, according to your preference and when you might use them. You can do as many batches as you prefer. And when it’s time to cook, just pour the veggies right into the pot. So easy.

Ingredients You Need

To make mirepoix, you need the following ingredients.

• Carrot: I use traditional full-size carrots when I prep mirepoix, though any type would work. You can even use baby carrots or shredded carrots if that’s what you have on hand.
• Onion: I prefer yellow onion, but white onion would work the same here.
• Celery: For freshness, look in the produce aisle for a head of celery that’s firm and has leaves without brown on them.

Step-by-Step Instructions

Here’s an overview of how to prepare mirepoix to use right away or to store for future use. Scroll down to the end of this post for more specifics.

1. Peel and trim the vegetables. Discard the ends (or save the scraps to simmer in water to make an easy veggie broth.)
2. Dice finely. (If you want the vegetables to be more finely chopped, you can also grind them in a food processor.)
3. Add some of each vegetable to a freezer bag or storage container.
4. Store and use as desired in recipes. (See below for ideas.)

How to Freeze Mirepoix

To freeze mirepoix, prepare your vegetables and then add to a storage bag in the portion you plan to use it in, which for me is 1 cup. Do your best to remove as much air as possible before sealing the bag.

You can freeze this mixture for up to 6 months.

There is often some ice that forms on the vegetables due to their water content, but that’s not a big deal or a worry. When you add it to a pot or a pan when using, simply sauté for a few minutes to allow the excess moisture to evaporate away.

Recipes to Use Mirepoix In

Below are my favorite recipes to use onion, celery, and carrots that are so fast to pull together once the veggies are chopped.
