Onions, Frozen

EverydayFrozen

Frozen onions are pre-chopped allium vegetables flash-frozen at peak freshness to preserve flavor and nutritional integrity. While slightly softer when cooked than fresh onions, they retain most original vitamin C and fiber content while eliminating prep work. Typically blanched before freezing to maintain color and texture stability, they perform well in cooked dishes like soups, casseroles, and sautés where subtle texture changes are less impactful.
