Delhaize Zilueruitjes (Silverskin Onions)

Delhaize Silverskin onions (Zilveruitjes/Oignons) are a staple private-label product of the Belgian supermarket chain Delhaize. These pickled onions are sweet and sour, commonly used in salads, garnishes, or as a snack.

Delhaize was founded in Belgium in 1867. In 2016, the company merged with the Dutch retailer Ahold to form Ahold Delhaize, which is now the ultimate parent company. While the brand is quintessentially Belgian, the raw materials and manufacturing for house-brand pickled goods like silver onions often come from various European suppliers depending on the harvest season, though they are primarily processed within the European Union to meet Belgian market standards.
