Caramelized Onions
4 large sweet onions, sliced 1/4 inch thick
1/4 c olive oil OR 3-4 tbsp butter
Pinch of salt
Heat olive oil or butter in a large cast-iron skillet over medium heat. Add the thinly sliced onions and cook for 5 minutes, stirring frequently, until the onions soften.
Reduce heat to low. If the onions aren’t deeply brown after 50 minutes and you’d like to speed things up, you can turn the heat higher to get more caramelization. Stir continuously to prevent burning.
