Oxford English Dictionary (Online version):

"To heat (meat or vegetables, etc.) in a pan with fat or water, in order to extract the juices.

Example: 1972 Guardian 18 Aug. 11/3 Finely chop one large onion and two cloves garlic. Sweat these in a little oil in a thick saucepan."

Traditionell in englisch-sprachige Küchen sagt man "to sweat" dazu, wie im Deutschen auch am häufigsten mit Zwiebeln.
