How to Store / Freeze This Salad
- To store the cold green bean salad, place it in an airtight container. Ensure the container is sealed tightly to maintain freshness and prevent any unwanted odors from seeping in.
- Keep the salad in the refrigerator. It will stay fresh for up to 3 days. The green beans may lose some of their crispness over time, but the flavors will meld beautifully.
- If you wish to prepare the salad in advance, consider storing the dressing separately. Combine the green beans, cherry tomatoes, and red onion in one container and the dressing in another. Mix them together just before serving to maintain the best texture.
- For freezing, note that green beans can be frozen, but the texture may change slightly upon thawing. Blanch the green beans for 2-3 minutes, then plunge them into ice water to stop the cooking process. Drain and pat dry before freezing.
- Place the blanched green beans in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together. Once frozen, transfer the green beans to a freezer-safe bag or container.
- Label the container with the date and contents. Frozen green beans can be stored for up to 3 months.
- When ready to use, thaw the green beans in the refrigerator overnight. Combine with fresh cherry tomatoes and red onion, and toss with the dressing just before serving.
- Avoid freezing the entire salad with dressing as the olive oil and vinegar may separate and alter the texture upon thawing.
