How Long Can Scallions Be Stored in the Refrigerator During Winter?

Green onions—also known as scallions or spring onions—are a versatile culinary staple rich in antioxidants, vitamin K, and dietary fiber. When stored properly during winter, their shelf life can be extended significantly compared to warmer months.

In refrigerated conditions—specifically at 0–4°C (32–39°F) with high humidity—fresh, unwashed green onions typically remain crisp and safe for consumption for 10 to 14 days. For optimal preservation, trim the roots slightly, wrap the bulbs loosely in a damp paper towel, and place them upright in a resealable plastic bag or airtight container in the crisper drawer. Avoid sealing tightly without ventilation, as excess moisture promotes mold growth.

Freezing is an option for longer-term storage but alters texture: blanching for 30 seconds followed by rapid cooling and freezing in portion-sized, airtight containers preserves flavor and nutritional integrity for up to six months. Thawed green onions are best used in cooked dishes rather than raw applications due to softened cell structure.

Signs of spoilage include slimy stalks, yellowing or browning leaves, soft or mushy bulbs, and off-odors—any of which warrant immediate discard. Notably, cold temperatures slow but do not halt enzymatic degradation; therefore, even under ideal winter refrigeration, quality declines gradually after two weeks.
