Mirepoix is traditionally 2 parts Onion, 1 part Celery, and 1 part Carrot. Now the amount and the size of the knife cut will vary based on what recipe you are going to use the Mirepoix in. Some times the recipe will call for a precision knife cut, other times larger rough chops would suffice.

Just make sure whatever size you do use, you stay consistent with all three vegetables so that they cook at the same rate.

When cooking Mirepoix, start on a low heat and add some butter or oil to a pan. First add your onions, and allow them a few minutes to cook, followed by your carrots and celery. Stir occasionally.
