What is Mirepoix?

If you’re not familiar with mirepoix, it’s a classic French flavor base that is used in many dishes. It’s a mixture of diced vegetables, usually onions, carrots, and celery, that are slowly cooked in butter or oil until they become soft and fragrant.

The ratio of vegetables can vary, but the most common combination is two parts onion, one part carrot, and one part celery. Other variations may include leeks, garlic, or bell peppers.

Mirepoix is an essential ingredient in many soups, stews, sauces, and braised dishes. It adds depth and complexity to the flavor profile of a dish, and it’s a great way to use up leftover vegetables.

One of the great things about mirepoix is that it’s versatile and can be customized to suit your taste preferences. You can add herbs like thyme, bay leaves, or parsley to enhance the flavor, or you can swap out the vegetables for others like fennel, parsnips, or turnips.
