# Expert Tips:

01 -
  • Everything comes together in one dish, leaving you with minimal cleanup on busy weeknights
  • The creamy sauce clings to every noodle, while that buttery crumb topping creates the most satisfying crunch against the tender pasta
  • You probably have most of these ingredients hiding in your pantry right now
02 -
  • Overcooking the pasta now means it will turn mushy in the oven, so pull it a full minute early
  • Whisking the sauce constantly prevents lumps from forming and ensures a silky consistency
  • Room temperature ingredients incorporate more smoothly into the sauce without separating
03 -
  • Greek yogurt works as a lighter substitute for sour cream if you are watching your intake
  • Mixing some grated Parmesan directly into the sauce adds an extra layer of savory depth
