Yesterday’s Chimichurri flank steak dinner becomes today’s steak tortilla with caramelized onions lunch. Mmmmmmm. 💃🏻 👩🏻‍🍳. Caramelized Onions INGREDIENTS
Several medium or large onions
Extra virgin olive oil
Butter (optional)
Salt
Sugar (optional)
Balsamic vinegar (optional) INSTRUCTIONS 1 Cut the onions root to tip: Slice 1/2-inch off the stem ends of the onions and the roots off of the root end. Place the onions cut side down on the cutting board. Cut them in half through the root end. Peel back the peels from the onions. 2 Heat olive oil and butter, add onion slices: Use a wide, thick-bottomed sauté pan for maximum pan contact with the onions. Coat the bottom of the pan with olive oil, or a mixture of olive oil and butter (about 1 teaspoon per onion). Heat the pan on medium high heat until the oil is shimmering. Add the onion slices and stir to coat the onions with the oil. Spread the onions out evenly over the pan and let cook, stirring occasionally. Depending on how strong your stovetop burner is you may need to reduce the heat to medium or medium low to prevent the onions from burning or drying out.
After 10 minutes, sprinkle some salt over the onions, and if you want, you can add some sugar to help with the caramelization process. (I add only about a teaspoon of sugar for 5 onions, you can add more.) One trick to keeping the onions from drying out as they cook is to add a little water to the pan.
3 Cook, stirring every few minutes: Let cook for 30 minutes to an hour more, stirring every few minutes. As soon as the onions start sticking to the pan, let them stick a little and brown, but then stir them before they burn. The trick is to leave them alone enough to brown (if you stir them too often, they won’t brown), but not so long so that they burn. You may want to lower the stove temperature a little, and add a little more oil, if you find the onions are verging on burning.
A metal spatula will help you scrape up the browned bits from the bottom of the pan as the caramelization proceeds. At the end of the cooking process you might want to add a little balsamic vinegar for flavor.
