Notes

Storage

This cheesy pasta is super tasty for leftovers, but it's not freezer-friendly because of that luscious cream sauce, which will get grainy when it freezes and thaws.

To Store: Leftover cheesy chicken alfredo spaghetti should be stored in an airtight container in the fridge. It will keep for 3-4 days. (These are my favorite airtight containers.)

To Reheat: Heat up leftovers in a non-stick skillet with a splash or two of heavy cream to help revive the sauce. I don't recommend microwaving these leftovers.
