How Long to Caramelize Red Onions

You may have heard that caramelizing onions takes at least an hour, but that’s not the case. With the help of brown sugar, you can caramelize onions in as little as 20 minutes. The addition of balsamic vinegar balances out the flavors, preventing the onions from becoming overly sweet.

Red Caramelized Onions Tips

Here are some tips to enhance your red caramelized onions experience:

  • If you prefer, you can use red wine vinegar, vermouth, or whiskey instead of balsamic vinegar.
  • While red onions offer fantastic flavor, you can also use sweet yellow or white onions.
  • Remember that onions shrink when caramelized, so it’s best to make extra and freeze any leftovers for future use.

How to Freeze Caramelized Onions

If you want to enjoy caramelized onions anytime, you can freeze them. Here’s how:

  1. Allow your onions to cool after cooking.
  2. Portion the cooled onions into a container of your choice. Ice cube trays work well for small portions, while freezer bags are suitable for freezing larger quantities.
  3. Freeze for up to 3 months, ensuring to label them with the freezing date.
  4. Use the frozen caramelized onions straight from the freezer. No need to thaw them beforehand. Simply add them to your dish and let them cook down along with the other ingredients.

(Note: When freezing caramelized onions, you may want to increase the amount you’re using. Simply double the ingredients in the recipe and cook double the amount.)
