As you can see, you can freeze red onions for quite a while. Weeks or months after placing them in the freezer you can take them out and use them to cook with.

Are Frozen Onions Good?

Red onions taste delicious in so many meals. If you have frozen some, you may be curious and ask the question, are frozen onions good?

Frozen red onions are good even after being stored in the freezer. They are perfect for adding to cooked dishes like soups, stews, or sauteing with other vegetables.
