How To Store / Freeze This Salad
To store your cold green bean salad, transfer it to an airtight container. This will help maintain its freshness and prevent any unwanted odors from seeping in. Place the container in the refrigerator, where it will stay fresh for up to 3 days.
If you plan to enjoy the salad over several days, consider storing the dressing separately. This will keep the green beans and cherry tomatoes from becoming soggy. Simply add the dressing just before serving.
For a quick refresh, give the salad a gentle toss before serving. This will redistribute the lemon juice and olive oil, ensuring every bite is flavorful.
If you need to freeze the salad, it's best to do so without the dressing. Blanch the green beans as directed, then spread them out on a baking sheet to freeze individually. Once frozen, transfer them to a freezer-safe bag or container.
When you're ready to enjoy the salad, thaw the green beans in the refrigerator overnight. Combine with fresh cherry tomatoes and red onion, then add the dressing just before serving.
Keep in mind that freezing may alter the texture of the green beans, making them slightly softer. However, the vibrant flavors of the dressing will still shine through, making it a delightful dish to enjoy any time.
