Lettuce can stay crisp without wilting for a week or more if stored with a simple paper towel, according to cook Kristin Marr, founder of Live Simply. The key is absorbing excess moisture that otherwise leads to slimy, mouldy leaves.
Why Lettuce Spoils Quickly
Lettuce has a high water content and a thin protective layer, making it susceptible to bacteria. Supermarket packaging protects during transport but traps moisture, creating a damp environment that accelerates spoilage. Most people store lettuce incorrectly, causing it to wilt within a day.
The Paper Towel Solution
Kristin Marr explains: “The towel will soak up extra moisture, keeping the greens from getting too wet which causes premature rotting and slimy greens.” A paper towel absorbs water that leaks from the leaves, keeping the surrounding air dry and preventing bacterial and mould growth.
How to Store Lettuce Properly
It takes less than five minutes to store lettuce correctly. Separate the leaves from the head and place them in a container (glass is best, but plastic or sandwich bags work). Add a paper towel around the leaves and another on top. Do not seal tightly; some airflow helps evaporation. Store in the fridge; lettuce should stay crisp for at least a week, often longer.
Additional Tips
For prepared salads, keep ingredients like tomatoes and cucumbers separate, as they release moisture that can spoil lettuce faster. Using a paper towel is one of the most effective ways to prevent mould, sliminess, and wilting, extending freshness by up to two weeks.
