Leftover pasta salad can be stored in an airtight container in the fridge for 3-4 days.
If you’re making the recipe in advance, you may want to reserve half the dressing until serving. The pasta continues to absorb the dressing as it sits but if you have some set aside you can freshen it up with reserved dressing at serving. In this case, prepare the dressing in a separate small bowl, mix half with the salad and store the other half in the fridge. This is optional. I just mix everything at once if I’m making this for meal prep but if I making in advance and serving to guests, I’d reserve some of the dressing to mix into the salad at serving.
