Ingredients

1/4 cup vegetable oil, such as safflower 

3 large onions, sliced 1/4 inch thick (about 4 cups) 

1 tablespoon peeled and chopped fresh ginger 

Kosher salt 

Preparation

Heat oil in a medium skillet over medium-high. Add onions and cook, stirring occasionally, until onions begin to brown on the edges and soften, about 5 minutes.

Reduce heat to low and add ginger to skillet. Continue cooking until onions are very soft and caramelized, 5 to 6 minutes more.

Remove from heat and season with salt.
