Ingredients

2 medium yellow onions sliced

Instructions

Heat a cast iron skillet over medium-high heat.
Add the onion slices and saute, stirring often but letting the onions char, until just the edges are blackened and crispy, about 15 minutes.
Remove from the heat and serve as a side dish or as a topping.

Notes

If you'd like to char the onions in some fat, I recommend oil over butter. Butter will burn at high heat. Use an oil that has a high smoke point like canola oil.
A cast iron skillet is best for getting the char on the onions, but any pan that can handle high heat will work.
I recommend at least ½ an onion per person as a serving. This is just enough for a small topping. Use more onion if you'd like larger servings.
Don't make the onion slices too thin, as you want burnt edges with soft, sweet middles of the slices.
Add a bit of flour and a bit of oil to the pan for crispy, fried onions.
