Costco's Organic Red Onions come in a convenient 5-pound bag, certified USDA organic and grown without synthetic pesticides or fertilizers. These bold, vibrant red onions are prized for their deep purple-red color, crisp texture, and mildly sweet yet pungent flavor that mellows when cooked.

Red onions are one of the most versatile cooking ingredients available. Use them raw in salads, salsas, and sandwiches for sharp, colorful bites, or caramelize them slowly to bring out their natural sweetness. They pair beautifully with Mediterranean, Mexican, and American cuisines, and are commonly used in pickling, roasting, and grilling applications. Their striking color also makes them a popular garnish.

Red onions are naturally low in calories and rich in dietary fiber, vitamin C, folate, potassium, and antioxidants including quercetin and anthocyanins, the compounds responsible for their red hue. These antioxidants are linked to anti-inflammatory and cardiovascular health benefits.
