The fertility of the Essonian soils ensures to the local agriculture a great variety of productions.

Many market gardeners are set up in direct sales in the area to offer seasonal fruits and vegetables. Essonne is the leading producer of watercress in France (30% of national production) and has the last artisanal producer of peppermint in Milly-la-Forêt. Saffron from Gâtinais (the most expensive spice in the world), oils, flours, artisanal pasta, vegetable terrines are also part of the local fabrications.
