# Expert Suggestions:

01 -
  • It transforms humble leftovers into something that feels restaurant-worthy and completely new.
  • The creamy sauce with nutmeg and thyme creates a flavor depth that makes people ask for seconds before they're even finished.
  • You can have it on the table in under an hour, making it perfect for weeknight dinners or last-minute entertaining.
02 -
  • Don't skip the resting time after baking—I learned this the hard way when I cut into a steaming casserole too early and it collapsed into a puddle on the plate.
  • Taste your sauce before it goes in the oven; you can season more easily now than after it's baked and set.
03 -
  • Make sure your sauce is actually thick before you combine it with the pasta—too thin and it'll separate during baking instead of staying creamy.
  • Brown your mushrooms properly in step three; they release their water first, then it evaporates, and only then do they develop real color and flavor. Don't rush it.
