red onion cut into long strips
Red onions are a good source of vitamin C and dietary fiber, and notably rich in anthocyanins and quercetin, phytonutrient compounds with antioxidant properties.
About
The red onion (Allium cepa var. aggregatum) is a cultivar of the common onion distinguished by its deep purple-red outer layers and reddish-purple inner rings. Native to Central Asia and naturalized worldwide, red onions contain anthocyanin pigments responsible for their distinctive coloration and possess a sweeter, milder flavor profile compared to yellow or white varieties. The bulbs range in size from small pickling varieties to large Spanish types, with flavor becoming notably sweeter when cooked.
Culinary Uses
Red onions are valued in both raw and cooked applications across global cuisines. Raw, they are sliced into rings for salads, salsas, pickles, and as a garnish for tacos and sandwiches, where their mild sweetness and visual appeal enhance dishes. When cooked—whether sautéed, caramelized, or roasted—they develop deeper sweetness and can be incorporated into stews, braises, and grain dishes. Cut into long strips (julienne or matchstick form), they work particularly well in stir-fries, fajitas, and slaws, where the shape promotes even cooking and textural presence.
