How to Keep Lettuce From Turning Brown | What Can You Do?

Although lettuce is often eaten in salads, it can also be used in sandwiches and wraps or as a garnish for various dishes. Lettuce is a non-starchy vegetable that provides almost no calories but has tons of fiber. Lettuce is known to prevent blood pressure from rising and helps against heart disease and kidney stones. Eating lettuce is an excellent way to increase your fiber intake without exceeding your daily limit. Lettuce is also rich in Vitamin A and Vitamin C. But it turns brown very quickly. Stop tossing those sad, brown lettuce leaves in the trash. Now store your produce correctly to keep it fresh and crisp!


The key is storage. Let’s start with the refrigerator: The best place for lettuce is at the bottom of the crisper drawer, where it can stay cold enough without drying out too much. If you like to wash your produce before refrigerating it, be sure to dry each leaf thoroughly before placing it in a plastic bag or container and then stick it in the fridge. However, not all lettuce varieties are created equal. If you think you have a bad case of lettuce rot that develops at the bottom of your refrigerator drawer, don’t toss yet another batch into your crisper drawer. Instead, remember that Romaine can stay a little longer than some other lettuces if they’re stored away from sunlight and heat. Did you know that your lettuce can go bad in as little as 4 hours? That’s why keeping your lettuce fresh for as long as possible is essential.

Tips on How to store Lettuce

  • Store Lettuce in the crisper drawer of your fridge and keep air away
  • Place a damp paper towel inside a plastic bag and cover the leaves
  • Use lemon juice or apple cider vinegar, having acidic properties that can help keep produce fresh
  • Sprinkle a little salt or sugar on your lettuce. Both will absorb moisture, which in turn keeps the leaves from wilting. 
  • Crisper drawer allows moisture to be absorbed from the air so that no wilting occurs

Another way to store your lettuce for a long time in the refrigerator is freezing. Freezing will increase the life of lettuce, and you can enjoy it throughout the month.

Freezing of Lettuce

If you store lettuce in your refrigerator for a long time, we recommend you freeze it first. In this way, the leaves will stay crispy and fresh even when stored cold. However, salting or rinsing the leaves before freezing them is not advised because these methods can cause deterioration in quality due to an accumulation of water droplets on the leaves’ surface, resulting in freezer burn. 

Freezing of Lettuce

Freezing lettuce retains its nutrition and flavor but will become limp and discolored after defrosting unless it was first packed in ice water. For best results immediately after defrosting and before eating, lettuce should be rehydrated by immersing it in ice water for 15 minutes.

Identifying the Right Lettuce

To keep your lettuce fresh for a long time, try to identify and buy only fresh lettuce from the supermarket. Sometimes the lettuce seems fine in the packaging but actually is not fresh. Here are a few tips for identifying fresh Lettuce:

1) Check the leaves for wilted signs: If you’re in a store and have no way to guarantee that the lettuce is fresh, you can always take a look at the outside of the head. If there are signs of wilting, it’s best to choose something else. 

Another great way to tell whether lettuce is past its prime is by looking at the leaves. Mangy leaves mean that the lettuce is old. In short, this means that they are either dead or dying. 

2) Check the stems: The stems of green lettuce will be sturdy. Stems on any other kind of lettuce will become soft and floppy over time. They should be soft and pliable when fresh, not a bit brittle! 

3) Check the leaves for yellowing or browning: If lettuce starts to age, it will start to look yellow or brown. The leaves will also become more prone to wilting over time.

4) Check the packaging: Depending on where you get your lettuce, there are a few things you can do to tell whether they are fresh or not. Based on how the packaging looks, you can determine whether the lettuce is still crisp and fresh or if it’s withering on the stalk.
