This delicious pasta does not often end up with any leftovers, but if you have some they can be stored in the fridge for up to 4 days. Simply transfer any leftover pasta to an airtight container. When you are ready for your leftovers, transfer the pasta to a microwave-safe dish covered with a paper towel. Microwave the leftovers for 1 ½ minutes, or until warm all the way through.
