Costco's 8-pound bag of fresh red onions is a bulk produce staple ideal for households and everyday cooking. Red onions are prized for their vibrant purple-red skin and mild, slightly sweet flavor that sets them apart from white or yellow varieties.

With their distinctive color and pleasant bite, red onions excel in raw applications such as salads, salsas, sandwiches, wraps, and ceviche, where their bold color adds visual appeal and their flavor brightens without overpowering. They are equally versatile when cooked — caramelizing beautifully in a skillet, roasting to tender sweetness in the oven, or grilling alongside proteins and other vegetables.

Red onions are also a popular choice for quick pickling: marinated briefly in vinegar and salt, they develop a vibrant magenta hue and tangy-sweet flavor that pairs perfectly with tacos, grain bowls, and charcuterie boards. The 8-pound bulk bag provides excellent value for families, meal preppers, and anyone who cooks regularly.
