Wash and Dry Thoroughly – If storing whole, do not wash until ready to use. Excess moisture can cause wilting. – If storing chopped, wash the leaves, then dry completely using a salad spinner or paper towels.
Wrap in Paper Towels – Wrap whole or chopped romaine in dry paper towels to absorb excess moisture. – Replace the paper towels if they become damp.
Store in an Airtight Container or Bag – Place the wrapped lettuce in a resealable plastic bag or an airtight container. – Leave a little air inside to prevent excess condensation.
Keep in the Crisper Drawer – Store in the vegetable crisper drawer of the refrigerator. – Ideal temperature: 32–36°F (0–2°C)
Avoid Storing Near Ethylene-Producing Fruits – Keep romaine away from apples, bananas, and tomatoes, as they release ethylene gas, which causes lettuce to spoil faster.
How Long Will Romaine Lettuce Last? – Whole heads: 10–14 days – Chopped leaves: 5–7 days
Properly storing romaine lettuce in a dry, airtight container with paper towels keeps it fresh and crisp for up to two weeks.
