Cauliflower and broccoli handle storage well if you limit their exposure to oxygen and heat, the two main culprits of food spoilage. To keep your broccoli and cauliflower fresh they have to start fresh; fresh broccoli has tight, green buds and fresh cauliflower firm, unmarred heads with no major blemishes. You can keep broccoli and cauliflower up to a couple weeks under the ideal storage conditions, but their exact shelf life depends on their freshness when purchased.

Things You'll Need

Trim your cauliflower and broccoli to fit into the storage bags or containers but keep them as whole as possible. The less oxygen that reaches the vegetables the longer they stay fresh.

Place each vegetable into its own food-storage bag or container. Cauliflower and broccoli release ethylene during storage, which shortens the shelf life of the other vegetables around them.

Mark the date on the storage containers and store them in a refrigerator set to below 40 degrees Fahrenheit between one and two weeks.
