Pick, store and use

  • Pick

    Choose onions that aren't bruised or damaged. (MSU Extension)

  • Store

    For keeping, trim the dry tops to 1–3 inches and leave the papery skin on. In cool, dry storage (35–55°F) onions can last 1–8 months. (MSU Extension)

  • Freeze

    MSU doesn't usually recommend freezing onions, since they store well dry, but chopped onions can be frozen without blanching for cooking. (MSU Extension)
