Add the onions to the skillet and increase the heat to medium-high. Cook until they begin to turn dark brown and somewhat soft, about 5 minutes.

Fully caramelized onions in five minutes more.
How to Saute Onions. In a large skillet or pan heat cooking oil or butter over medium-high heat until hot. Use about 1 tablespoon fat per onion.

If desired, cook a little longer until edges just start to brown. Remove from heat and use as desired.
