Learn how to freeze green onion to preserve it for later use! Plus, you’ll learn how to use frozen green onions in delicious recipes.
Green onions are such a versatile ingredient! It’s great to have a stash of them in the refrigerator. However, when you bought too many of them at the store or grew a ton in your backyard garden, you may be curious how to preserve them so they don’t end up going bad! Read on to learn how to freeze green onion.
Wash, trim, and slice the green onions. See my tutorial on How to Cut Green Onions for more information. Be sure to pat them dry after you wash them to remove any excess water before freezing. You don’t want ice crystals to form on them!
Spread the sliced green onions out on a lined baking sheet. Put it in the freezer, somewhere it won’t get bumped, for about an hour or until frozen solid. Transfer the onions to freezer bags, such as Stasher bags, and store in the freezer.
You do not need to blanch scallions before freezing. They can be frozen from raw, but keep in mind they won’t keep as long as vegetables that were blanched before freezing. Still, it’s preferable to freeze them raw because they are fairly delicate and may lose too much of their texture if blanched.
Fresh green onions that are properly stored in freezer-safe airtight containers or bags with as much air as possible removed will last for 3 to 4 months in the freezer. Remember to pat them dry before freezing to prevent ice crystals from forming.
Frozen green onions will lose some of their flavor during the freezing process. They will be slightly milder but still taste delicious.
When thawed, frozen green onions can get mushy. That’s why it’s recommended to use them in hot or cooked dishes and not in raw preparations.
You can use frozen green onions in hot dishes. Substitute them for other kinds of onions in soups, stir fries, or casseroles. They can be used in place of fresh onions in my Healthy Breakfast Egg Muffins with Mushrooms and Scallions. Or, use them as a garnish for a warm recipe like tacos or rice. You do not need to thaw frozen scallions before using them in cooking. They will thaw quickly as soon as you add them to a hot dish.

How to Freeze Green Onion
- Lined baking sheet
- Freezer bag or container
- 1 bunch green onions
- Wash the green onions under running water, using your fingers to scrub off any dirt. Remove any wilted leaves and discard. Pat dry.
- Trim the green onions then slice them into pieces.
- Spread the slices out on a lined baking sheet. Place the sheet in the freezer, somewhere it won't get bumped, for about an hour or until frozen solid. Alternatively, you can skip this step but I like to flash freeze them so they don't clump together as much in the freezer.
- Once frozen, transfer the slices to freezer-safe bags or containers. Remove as much air as possible, seal tightly, and label.
- Store in the freezer for up to 3 to 4 months.
- Use frozen green onions directly from frozen (do not thaw) in hot dishes. They should not be served in raw dishes, since they will get mushy.
