Red Onions, Frozen

Red Onions, Frozen

EverydayFrozen

Red onions, frozen are pre-chopped and blanched red onions preserved at peak freshness to maintain their vibrant color and nutritional value. The freezing process softens their raw pungency while retaining their anthocyanin antioxidants, which give the onions their characteristic purple hue. Ideal for cooked dishes, they offer convenient use directly from frozen in sautés, soups, and stir-fries, though their thawed texture becomes more tender compared to fresh onions.
