The ultimate secret to rich, restaurant-quality cooking lies in a humble trio of vegetables known in French cuisine as a mirepoix, and in Italy as a soffritto or battuto. Traditionally this is a mix of onions, carrots, and celery, you can easily upgrade this base by adding fennel for a subtle, anise sweetness, chili or garlic or even ginger will add a warming kick.
To unlock maximum flavor, grab a good, large chopping knife and cut the vegetables into very small pieces; this increases their surface area, allowing them to release a massive concentration of savory goodness into your food.
For a professional chef’s twist, roast the mix gently in an almost dry frying pan first over medium-low heat to lightly toast so that the natural sugars caramelise and to draw out moisture, then only add the smallest amount of olive oil to stop sticking.

This aromatic powerhouse is the perfect flavor anchor for an endless variety of comforting dishes, serving as the essential foundation for rich Bolognese, ragùs, hearty stews, comforting soups, and velvety pan gravies. It can also be instantly added to fried rice dishes or noodles.
Because prep takes time, this mix is incredibly meal-prep friendly; you can easily chop a massive batch in advance and freeze it in airtight bags for later use.
When you are ready to cook on a busy weeknight, simply drop the frozen veggies straight into your hot pan – no thawing required – to instantly elevate your meal from ordinary to extraordinary.
