How to Caramelize Onions the Right Way

Heat a teaspoon of neutral oil for each onion over medium-high heat in the bottom of a large skillet or dutch oven (use whatever cooking vessel has the largest surface area on the bottom). When the oil is just-shimmering, transfer the sliced onion to the skillet (we like to use a bench scraper to make this easier). Once you add the onions, toss them to coat with the oil and gently break up the onion slices.
