You can indeed freeze red onions, and it's a total game-changer for meal prep and reducing food waste. Simply chop or slice the onions, blanch them in boiling water for a few minutes to inactivate the enzymes that cause spoilage, and then freeze them in airtight containers or freezer bags. This way, you can enjoy their sweet flavor and crunchy texture in stir-fries, soups, and salads all year round!
Now, you might be thinking, "But won't they lose their texture and flavor when frozen?" Well, not necessarily! Frozen red onions can be just as tasty and crunchy as fresh ones, as long as you freeze them properly. And the best part? Frozen onions are super convenient to use in recipes, as they're already chopped and ready to go!
