How to Store Lettuce to Keep Crisp

Nothing is more disappointing than reaching for lettuce and finding a wilted, slimy mess. With the right storage method, you can keep lettuce crisp and fresh for up to two weeks. Here's exactly how to store lettuce to keep it crisp.

Why Lettuce Goes Limp

Lettuce wilts for two main reasons: moisture loss and excess moisture. Too little humidity and the leaves dry out and wilt. Too much moisture sitting on the leaves causes sliminess and rot. The goal is to maintain the right balance — high humidity around the leaves, but no standing water touching them.

How to Store Whole Head Lettuce

1. Don't wash before storing — Moisture on the leaves accelerates rot. Wash only right before eating.
2. Remove damaged outer leaves — Discard any wilted or brown leaves before storing.
3. Wrap in a dry paper towel — Wrap the whole head loosely in a Sparkle Paper Towel. The towel absorbs any excess moisture while keeping the leaves from drying out.
4. Place in a bag or container — Store the wrapped head in a SPLF Reusable Bag with a little air left inside, or in a large ComSaf Airtight Container.
5. Store in the crisper drawer — Set to high humidity for best results.

How to Store Chopped or Torn Lettuce

1. Wash and dry thoroughly — Use a salad spinner to remove as much water as possible. Wet lettuce goes slimy fast.
2. Line a container with paper towels — Place a dry paper towel at the bottom and sides of an airtight container.
3. Add lettuce and top with another paper towel — The towels sandwich the lettuce, absorbing any residual moisture.
4. Seal and refrigerate — The ComSaf Airtight Food Storage Containers are ideal for this — they come in large sizes and seal well.

The Herb Keeper Method for Romaine

For romaine and other upright lettuces, the OXO Good Grips GreenSaver Herb Keeper works surprisingly well — stand the romaine upright with the base in a small amount of water, cover with the lid, and refrigerate. This mimics how the plant grows and keeps it crisp for longer.

How Long Does Lettuce Last in the Refrigerator?

• Whole head (unwashed, paper towel wrapped): 1–2 weeks
• Chopped lettuce (paper towel lined container): 5–7 days
• Pre-washed bagged lettuce: use by the date on the bag

Signs Lettuce Has Gone Bad

• Slimy or mushy leaves
• Brown or black edges throughout
• Foul or sour smell
• Pink or rust-colored discoloration
