How to Store Lettuce & Leafy Greens For Weeks

Wash the Lettuce: Separate the lettuce leaves and rinse them thoroughly under cold running water to remove any dirt or debris.
Dry the Lettuce: Use a salad spinner to remove excess water from the leaves. If you don’t have a salad spinner, pat the leaves dry with paper towels. Ensuring the lettuce is dry is crucial to prevent it from becoming soggy.
Chop or Tear the Lettuce: If you would like, you can chop or tear the lettuce into bite-sized pieces, depending on your preference. I like to leave our leafy greens in tact.
Pre-cool the Mason Jars: If you prefer, you can chill the mason jars in the fridge for about 30 minutes before using them. This step is optional but can help keep the lettuce cool.
Add a Paper Towel: Placing a small piece of paper towel at the bottom of the jar before adding the lettuce can help absorb any excess moisture and keep the lettuce fresh longer.
Pack the Lettuce into the Mason Jars: Fill the mason jars with the dry lettuce pieces. Pack them loosely to avoid crushing the leaves.
Seal the Jars: Place the lids on the jars and seal them tightly by hand or by using a jar vacuum sealer.
Store in the Fridge: Place the sealed mason jars in the refrigerator.
