Storage and reheating notes: This white sauce pasta is best served immediately, but leftovers last up to 3 days in the fridge (I don’t recommend freezing it). The sauce will become very thick as it cools. To reheat, add a splash of milk to loosen the sauce and warm it gently on the stovetop over low heat, stirring frequently. You could also microwave leftovers for a few seconds at at time, adding liquid if necessary.
