How Long Does Cauliflower Last?
Shelf Life and Storage Tips
Cauliflower, a nutritious and versatile vegetable, is a staple in many kitchens due to its ability to enhance a variety of dishes. Its shelf life, however, can vary depending on how it's stored. Understanding the factors that affect how long cauliflower lasts is essential for minimizing waste and ensuring the vegetable's best quality when used in cooking.
When stored properly in the refrigerator, a whole head of cauliflower has a shelf life of approximately 7 to 10 days. Maintaining the freshness of this cruciferous vegetable involves keeping it dry and cool, thus inhibiting the growth of mold and the acceleration of spoilage processes. Precut cauliflower florets, while convenient for quick cooking, often have a slightly shorter refrigerated lifespan of about 4 days, due to their greater exposed surface area which can lead to quicker degradation.
