Can You Freeze Red Onions?

Yes, you can freeze red onions. These onions can be frozen either after or before blanching. When freezing whole onion bulbs, you must blanch them. For small onions, blanch for three minutes; for larger onions, blanch for seven minutes. When blanching onions, the entire bulb must be heated for safe freezing.

If you chop frozen onion pieces extremely finely in a food processor, your finished product might resemble mush because thawed onions tend to lose their shape. Place a thin layer of chopped onions in zipper bags. Cut off a piece of the frozen layer to use.

Instructions to Freeze Red Onions

It’s not quite the best idea to grab a handful of red onions and throw them in the freezer. You’ll need to follow a few steps in order to successfully freeze them:

  • Prepare: Before removing the onion’s outer skin and top layer, cut top and tail each onion that you intend to freeze.
  • Cut Up: At this point, cut the onion into its component parts as usual. It can be divided into small cubes, half moons, slices, and wedges. You have the choice. The onion should be divided up and placed in small freezer bags. Think about how much you use when cooking and put this amount of frozen food into each bag.
  • Seal: Tightly close the bags, squeezing out any remaining air. You can accomplish this by 90%-sealing the bag, completely pressing out the air, and then 90%-sealing the bag.

Place the bag in the freezer, making sure it is reachable. The bags should then be taken and lightly shaken after 30 minutes. By doing this, the onion pieces won’t bunch up too much.
