How to Make Caramelized Onions

If you’re looking for the best caramelized onions recipe, look no further! This easy recipe is perfect for topping off your favorite dishes. Simply follow the instructions below and you’ll have delicious, caramelized onions in no time.

Start with a quality onion. We like to use sweet onions, but you can use any type of onion that you prefer. Just make sure that they are fresh and not pre-sliced.

  1. The first step is to slice the onions thinly. This can be done by hand with a sharp knife, or with a mandoline slicer if you want uniformity. To slice onions with a knife, remove both ends of onion and cut in half lengthwise. Turn one piece of onion onto flat side and cut into thin slices, working from one end to another. Repeat until all onions are sliced. Thin slices allow the onions to Caramelized more evenly.
  2. Melt a bit of butter in a large nonstick pan or cast-iron skillet over medium-low heat. Add onion slices to skillet and drizzle a little olive oil over the top. Season with salt and black pepper, to taste, and stir to combine.
  3. Spread the onions out in the pan so that they are in a single layer and slowly cook the onions down over medium heat for 45 minutes to an hour until the onions are golden brown and caramelized. (Total cooking time will depend on how high your heat is, the number of onions used, the sugar content in the onions, and how old they are). Stir the onions every 5 or 10 minutes while they are cooking to prevent scorching.
  4. Once the onions are done caramelizing, add balsamic vinegar to deglaze the pan. While the liquid is bubbling, gently scrape the bottom of the pan with a wooden spoon to incorporate the fond (the browned bits on the bottom of the pan) into the onions.
  5. Season with a pinch of salt and black pepper, if desired. Use immediately, or cool and store in the refrigerator in an airtight container for up to one week. Enjoy!

Tips for Making the Best Caramelized Onions

  • Start with high quality onions. This is the most important step for making great caramelized onions. Choose sweet onions like Vidalia or Walla Walla, or pungent onions like yellow Storage onions.
  • Cut the onions into thin, even slices. This will help them cook evenly and prevent them from burning.
  • Add a bit of fat. This will help the onions cook slowly and prevent them from sticking to the pan. You can use butter, olive oil, or bacon fat.
  • Cook the onions over low heat. This may take a while, but it’s worth it! Caramelizing onions is a slow process and if you try to rush it, they will burn.
  • Stir often and be patient. Once the onions start to caramelize, they will need to be stirred frequently to prevent them from burning. Be patient and keep an eye on them – they’re done when they’re a deep golden brown color and are very soft.
  • Season to taste. Once the onions are done, season them with salt and pepper to taste. The splash of vinegar during cooking gives the onions a great flavor, but you can also add other herbs and spices at the end if you’d like.
