How to choose green onion

Green onions, or scallions, should have crisp, bright green tops and a firm white base. They should stand upright when held. Sniff the green onions to ensure they have a fresh, sharp scent.

Do not use green onions that have wilted tops or slimy bulbs, as these are indications they are no longer fresh. Good green onions should add a mild, peppery flavor to dishes without being overpowering.

How to store green onion

Green onions should be kept in the refrigerator. Store them in a container with a bit of water and loosely cover with a plastic bag to help retain their freshness. When stored correctly, green onions can remain fresh for 1-2 weeks.

Improper storage can lead to wilting and a decline in flavor. It is advisable to refrain from washing them prior to storage to maximize their longevity. Ensuring they have some airflow will help preserve their crispness and vibrant taste, making them ideal for garnishing and cooking.

✅ Extra Tip

To keep green onions fresh even longer, you can store them upright in a glass of water in the refrigerator, changing the water every few days to maintain freshness.

How long does it last?

Green onions can last for 1-2 weeks in the refrigerator. To keep them fresh, store them in a plastic bag or container with a paper towel to absorb excess moisture. For best results, keep them in the crisper drawer of the refrigerator.

What to do with leftovers?

Leftover green onions can be used in a variety of dishes to add a fresh, mild onion flavor. Chop them and sprinkle over salads, soups, or pasta dishes as a garnish, or mix them into scrambled eggs, omelets, or frittatas for a flavorful breakfast.

Use green onions in a cream cheese or sour cream dip, or blend them into a butter to spread on bread or melt over grilled meats. If you have a lot of green onions, consider making a batch of scallion pancakes by mixing the chopped onions into a batter and frying until golden. Green onions can also be used as a topping for potatoes, whether baked, mashed, or roasted, or added to a stir-fry with vegetables and rice. For a quick snack, try sprinkling green onions over cottage cheese or mixing them into a yogurt-based dip for vegetables.
