Can you freeze garden fresh green onions?

Freezing green onions is a great way to preserve the fresh flavor of garden onions to enjoy year round. When frozen properly, green onions retain their flavor, texture, and nutritional value very well. Here’s what you need to know about freezing green onions.

Can You Freeze Whole Green Onions?

Yes, you can freeze whole green onions, including the white bulb and green stalks. To freeze whole green onions:

  • Choose fresh, firm green onions. Avoid any that are wilted or mushy.
  • Trim off any brown or damaged parts of the green onion.
  • Rinse the green onions under cool water and pat dry thoroughly with paper towels.
  • Place the whole onions in a single layer on a baking sheet or tray. Make sure they are not touching.
  • Place the baking sheet in the freezer for 1-2 hours until the onions are completely frozen.
  • Transfer the frozen green onions to an airtight freezer bag or container. Squeeze out excess air before sealing.
  • Store the frozen green onions in the freezer for up to 3 months.

Freezing the green onions in a single layer first prevents them from freezing together in a clump. Once frozen solid, they can be stored together in a freezer bag or container without sticking together.

Can You Freeze Chopped Green Onions?

Chopped green onions can also be frozen successfully. To freeze chopped green onions:

  • Thoroughly wash and dry fresh green onions.
  • Trim off roots and any dried or damaged pieces.
  • Chop the green onions into desired sizes – sliced, diced, etc.
  • Spread the chopped onions in a single layer on a baking sheet lined with parchment paper.
  • Place in the freezer for 1-2 hours until completely frozen.
  • Transfer the frozen chopped onions to an airtight freezer bag or container, removing as much air as possible.
  • Store in the freezer for up to 3 months.

Chopping the onions before freezing helps them thaw more quickly later on. Just grab a handful from the freezer to throw into recipes.

Can You Freeze Green Onion Whites and Greens Separately?

Yes, you can separate the white and green portions of green onions for freezing. Sometimes recipes call for just the white bulbs or just the green tops.

To freeze the whites:

  • Trim off the green tops, leaving just the white bulb and root end.
  • Rinse and dry the whites well.
  • Place in a single layer on a baking sheet and freeze for 1-2 hours.
  • Transfer to an airtight freezer bag or container.

To freeze the greens:

  • Trim off the white bulb portion.
  • Rinse and dry the green tops well.
  • Chop the greens if desired.
  • Spread in a single layer on a baking sheet and freeze for 1-2 hours.
  • Transfer to an airtight freezer bag or container.

Storing the whites and greens separately lets you easily use just the portions you need.

Can You Freeze Green Onions in Oil or Water?

Green onions can be frozen in oil or water. This helps prevent freezer burn which can cause discoloration and texture changes. Here are some tips:

  • Oil: Combine chopped or sliced green onions with a bit of olive oil or vegetable oil (about 1-2 tablespoons per 1 cup onions). Freeze in a single layer then transfer to airtight containers.
  • Water: Place green onion pieces in ice cube trays and cover with water. Freeze until solid, then transfer cubes to freezer bags.

The thin layer of oil or water protects the green onion pieces during freezing. Make sure to label ingredients and date the freezer containers.

What is the Best Method for Freezing Green Onions?

The best way to freeze green onions for versatility and convenience is:

  • Clean and dry onions well.
  • Trim off roots and any damaged parts.
  • Chop onions into desired sizes – sliced, diced, etc.
  • Spread pieces in a single layer on a parchment-lined baking sheet.
  • Freeze for 1-2 hours until solid.
  • Transfer to airtight freezer bags or containers, removing excess air.

Chopping the onions before freezing makes them easier to use. The single layer prevents them from freezing into a solid clump. Airtight freezer storage bags or containers prevent freezer burn or ice crystals.

Refrigerator thawing is best to prevent a waterlogged texture. Use thawed green onions right away for maximum freshness.

Cooking With Frozen Green Onions

Frozen green onions can be cooked, added to soups, stews, casseroles and more. Because they are already chopped, they are quick and convenient to use from the freezer. Here are some tips:
