Notes

  • Swap spaghetti for other pasta types like penne or rotini.
  • Add hot sauce or use pepper jack cheese for a spicier version.
  • Use rotisserie or grilled chicken to save time and add flavor.
  • Freeze before baking for up to 2 months; thaw overnight before baking.
  • Lighten it up by using reduced-fat cream cheese and sour cream.
