Keeping One Pot French Onion Pasta Fresh

  • Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Cover the pasta completely to prevent it from drying out and absorbing other food odors.
  • Warm the pasta in a pot over low heat, adding a splash of beef broth or water to restore moisture and prevent sticking. Stir frequently to maintain the creamy texture.
  • Transfer cooled pasta to a freezer-safe container, leaving some space for expansion. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
  • Cream-based pasta dishes are best enjoyed fresh. The texture and flavor can change significantly after extended storage, so try to consume within the first couple of days for optimal taste.
