YES, you can freeze onions!

Who knew?! This is one of those food prep tips that I should have shared years ago because I love it so much. Onions freeze beautifully and can be added to so many recipes.

Ready to go!

Having onions prepped, chopped or sliced and ready to add to recipes is the best! My favourite time to do this is in summer or fall when I have more onions that I know what to do with, either from my garden or from a farmers’ market haul. I’ll just take a moment and chop and slice, and my future self always thanks me! I just reach into the freezer, scoop out what I need and get cooking.

Tips & Tricks

  • Onions: You can freeze any kind of onions: green, white, yellow, sweet, purple, chives… You can even freeze any leftover onions you have in your vegetable crisper.
  • What to freeze them in: I like to keep frozen produce in labelled freezer ziplock bags. When freezing onions make sure you use freezer bags because they’re thicker and will help to keep the strong smell of onions inside. You can also use plastic or glass containers, just make sure they are airtight.

How to Use Frozen Onions

Frozen onions can be added to recipes for soups, stews, casseroles, bakes, and chili, and to any recipe that requires sautéed onions. Because freezing changes the texture of onions, don’t use frozen onions in any dish like salads, dips, or salsas that require fresh onion.

Do I have to thaw the onions before using them?

Nope! You can add them frozen right into your recipe.
