Give Your Stove A Rest And Make Caramelized Onions In Your Slow Cooker

How to use and store your slow cooker caramelized onions

Once you have a slow cooker brimming with perfectly caramelized onions, the possibilities for using them are endless. You can simply layer them over a succulent steak prepared using chef José Andrés' low-heat method, or stack them on a delicious patty melt topped with gooey Swiss cheese. They also serve as a delightful sweet and savory garnish for burgers, brats, hot dogs, or grilled chicken. Additionally, you can transform them into a tasty onion dip, ideal for parties, game days, or casual snacking. Any leftovers can be kept in the refrigerator for up to a week in an airtight container. Alternatively, freezing them for later use is highly recommended, ensuring you have caramelized onions on hand whenever you need them!

There are various methods to freeze caramelized onions. One approach is to portion them into small amounts in freezer bags, flattening the bags to remove as much air as possible. We suggest avoiding the storage of all your caramelized onions in a single bag, as it will be challenging to portion them out once frozen if you don’t plan to use them all at once. Another option is to freeze the onions in an ice cube tray; once they are frozen, you can transfer them to an airtight container or freezer bag. We prefer this method because it allows for easy access to precise portions of onions whenever needed. When frozen, caramelized onions can last for several months in your freezer.
