Mastering How To Make Mirepoix: How-To

Step 1: Prepare Your Vegetables
Start by washing your vegetables thoroughly. Peel the onion and chop it into 1/2-inch pieces. For the carrot, peel the skin and then slice it into 1/2-inch chunks. Finally, chop the celery rib into 1/2-inch pieces as well. The key is to keep the pieces uniform so they cook evenly.
Step 2: Heat the Olive Oil
In a large skillet or sauté pan, heat 1 tablespoon of olive oil over medium heat. Allow the oil to warm up for about a minute until it shimmers. This step is essential as it helps to release the flavors of the vegetables as they cook.
Step 3: Sauté the Onion
Add the chopped onion to the skillet first. Sauté the onion for about 3-4 minutes, stirring occasionally until it becomes translucent and fragrant. This is where the base of your mirepoix begins to develop its rich flavor.
Step 4: Add the Carrot and Celery
Once the onion is soft, add the chopped carrot and celery to the skillet. Stir everything together and continue to sauté for an additional 5-7 minutes. You want the vegetables to soften but not become mushy. Keep stirring occasionally to prevent sticking.
Step 5: Season and Enjoy
At this point, you can add a pinch of salt and pepper to enhance the flavors, but feel free to adjust this based on your preferences. Once the mirepoix is fragrant and tender, it’s ready to be used in your favorite recipes or stored for later.
If You’re Out Of…

- Olive oil: Substitute with vegetable oil or coconut oil.
- Onion: Use shallots or leeks as an alternative.
- Carrot: Sweet bell peppers or parsnips can be used instead.
- Celery: Fennel or even zucchini can work in a pinch.
Mistakes That Ruin How To Make Mirepoix
While mirepoix is straightforward, there are a few common pitfalls to avoid:
- Overcooking the vegetables can lead to a mushy texture, which loses the desired crunch.
- Using unevenly sized vegetable pieces can result in inconsistent cooking times.
- Skipping the sautéing step means you miss out on the depth of flavor that develops during cooking.
- Not adjusting the heat accordingly can cause the mirepoix to burn or stick to the pan.
Freezer-Friendly Notes
One of the great things about mirepoix is that it can be made in large batches and frozen for later use. To freeze, allow the mirepoix to cool completely after cooking. Portion it into airtight containers or freezer bags, and label with the date. When you need a flavor base, simply pull out the portion, thaw it, and add it directly to your recipe!
