Updated: April 17, 2022

Green onions are a staple in many dishes, whether it be a garnish or a main ingredient. However, cleaning them can be a bit tricky. Here are some steps to ensure that your green onions are clean and ready to use.

Step 1: Trim Roots and Tops

Before cleaning your green onions, it’s important to trim off the roots and the tops of the plant. You can do this by using a sharp knife or kitchen scissors. Cut off the root end, leaving about 1/4 inch of the white part intact. Then, cut off the tops of the plant, leaving only the green stems.

Step 2: Rinse in Water

Once you’ve trimmed your green onions, rinse them well in cold water. This will help remove any dirt or debris that may be stuck to them. Make sure to separate each stem so that water can reach all parts of the plant.

Step 3: Soak in Saltwater

After rinsing, soak your green onions in saltwater for about 10 minutes. This will help kill any bacteria that may be present on the plant. To make the saltwater solution, add 1 tablespoon of salt per 4 cups of water.

Step 4: Rinse Again

After soaking, rinse your green onions in cold water once more to remove any remaining saltwater solution.

Step 5: Dry Thoroughly

Finally, dry your green onions thoroughly using paper towels or a clean kitchen towel. You can also use a salad spinner to remove excess water from the stems.

By following these steps, your green onions should be clean and ready to use in your favorite dishes.
