Buying Leafy Greens In Bulk? Here's How Long They Really Last

In an effort to sneak more leafy greens into your diet, you have probably considered buying them in bulk before. It may seem like the epitome of kitchen convenience, until you open the fridge and find those greens disappointingly wilted or soggy, a far cry from the verdant leaves seen at the store days ago. We're here to help you avoid that happening. You just need to know how long those leafy greens really last and the best storage methods to preserve their freshness.

The average lifespan for bagged leafy greens ranges from just 4 to 5 days. In case you were wondering, pushing past the expiration dates on the label is not recommended due to the potential risk of foodborne illnesses. Moreover, once a pre-prepared package is opened and the leafy greens are exposed to even more contaminants, they are best used within two days. Fresh greens sold loose are a way better bet, as they can last up to 10 days. Needless to say, unless you're absolutely sure you're going to use them up within the first five days of purchase, it might not be such a good idea to buy any leafy greens in bulk. Fresh is definitely best here. If you already have a few bags sitting on the kitchen counter, make sure to take all the necessary storage steps to maintain their quality.

As mentioned above, bagged leafy greens should remain inside their packaging until the moment you're ready to use them. If you've opened the bag and still have not finished with the greens, consider transferring them to a spacious airtight container, lined with paper towels at the top and bottom — a foolproof method to store greens for a clean, crisp salad every time as the towels absorb excess moisture. Don't forget to replace the towels every couple of days. Much like most other fresh produce, the crisper drawer is the best place to store leafy greens, preferably when the fridge is set at a stable temperature below 40 degrees Fahrenheit. However, be careful not to leave them near ethylene-rich fruits like avocados, since this gas could cause them to wilt faster.

Additionally, always remember the golden rule of storing fresh greens without washing them first — especially if you've opted for pre-washed or ready-to-eat varieties. This is because the excess moisture can potentially give veggies a slimy coating and accelerate the spoilage process — not to mention exposing them to cross-contamination with other ingredients on your kitchen counter. If you do see a few leaves getting slimy, soggy, or straight-up wilting, cut them off to avoid further damaging the bundle. Other signs of spoilage, such as yellowed, discolored leaves and a foul odor, should also be noticed. Most often, they start at the bottom of the bag.
