How to Store and Freeze Lao Cucumber Salad
Fridge: Store leftovers in an airtight container in the refrigerator for up to 1 day. The salad is best enjoyed fresh, as dressing can make cucumbers soggy over time.

Freezer: It’s not recommended to freeze Lao cucumber salad, as the texture of cucumbers and tomatoes will degrade upon thawing. For a quick meal, prepare the components and dress just before you eat.

Lao Cucumber Salad Recipe FAQs
How do I choose the perfect cucumbers for this salad?
Absolutely! Look for cucumbers that are firm, smooth, and free of blemishes. I often use Japanese or English cucumbers as they have a thinner skin and are less bitter. If there are dark spots all over, it’s best to avoid those.
How long can I store leftovers of the Lao cucumber salad?
Leftovers can be stored in an airtight container in the refrigerator for up to 1 day. I recommend enjoying it fresh, as the dressing can make the cucumbers soggy. If you want to prepare it ahead of time, consider storing the dressing separately and tossing it with the salad just before serving.
Can I freeze Lao cucumber salad?
It’s not recommended to freeze this salad, as the cucumbers and tomatoes will lose their crisp texture upon thawing. Instead, if you’re looking to meal prep, prepare the ingredients and dressing separately. Combine them just before eating for the best experience.
What if I’m allergic to fish sauce?
No problem at all! You can replace fish sauce with soy sauce for a vegetarian option or use a gluten-free fish sauce if needed. Just be sure to check the label for any allergens.
What should I do if the salad tastes too salty?
If you find the salad too salty from the fish sauce, add a touch more lime juice or a sprinkle of palm sugar to balance the flavors. Also, feel free to add extra cucumbers or tomatoes to dilute the saltiness.
How can I make this salad spicier?
If you’d like more heat, simply add more chilies to your dressing! Start with a small amount and taste before adding more. The more, the merrier when it comes to the warmth in this Lao cucumber salad recipe!
