Ingredients
- 4 lbs medium or large yellow onions
- 6 tablespoons unsalted butter
- 2 tablespoons olive oil
- 2 tablespoons packed dark brown sugar
- 2 teaspoons kosher salt
Instructions
- Use a sharp knife to cut the onions in half from the root to the tip. Then use a paring knife or the tip of your knife to cut a V-shape around the root and remove it, and then cut a bit of the tip (end) off.
- Place an onion half on the cutting board and thinly slice the onion lengthwise into half moons, about ¼-inch thick or so. Use a bench scraper to gather the onions and place them into a large mixing bowl. Repeat the same slicing process until all the onion halves have been prepped. Note: There will be a lot of onions, but they will cook down significantly.
- In a large, wide, and deep pot over medium heat, add the butter and oil. When hot, gently swirl the pot to evenly coat the bottom.
- Working in batches so as not to overwhelm the pot at one time, add a handful of onions to the pot. Use a wooden utensil to cook, stirring often, until the onions are soft and translucent, about 2 minutes. Then add more onions and repeat the cooking process until you’ve added all of the onions to the pot.
- Reduce the heat to medium-low and continue to cook the onions, stirring them every so often for even cooking and to prevent them from sticking. The process of rich + deeply caramelized onions can take anywhere from 45-50 minutes, sometimes a bit longer. The onions will start with a light blonde color and then take on a golden amber hue, and then transform into a deep dark color with crisp edges. During the cooking process (right around when the onions achieve their golden coloring, most of the water content will cook off). As such, it’s important to continue to keep an eye on the onions and stir every so often to prevent burning/scorching.
- Once the onions have reached that deep brown color, season the onions with the brown sugar and salt. Continue cooking, stirring the spices in until well combined, about 5-7 minutes. Then remove from the heat and let the caramelized onions rest in the pot until cool. The onions should be soft and jammy and deeply fragrant.
- Transfer the cooled caramelized onions into an airtight container and keep stored in the fridge. The onions will keep for up to 1 week. To serve: make caramelized onion dip, French onion soup, add to burgers/sandwiches, eggs, top focaccia, and more. Enjoy!
