Notes
Frozen onions will be safe indefinitely if kept at below zero degrees, but after ten months, their quality will start to diminish. Since home freezers are not as consistent and reliable as commercial freezers, try to use your frozen onions within a couple months.Use onions in sautés, stir-fries, soups, chilis, and stews. They are also good in sauces and gravies, and go well with roast meat dishes.
