# Expert Advice:

01 -
  • It's the comfort of two beloved dishes merged into one, so you get both the cheese pull and the savory meat sauce in every forkful.
  • Feeds a crowd without requiring you to make multiple components—everything layers together in one baking dish.
  • Comes together in about an hour, making it perfect for weeknight dinners when you want something that tastes like you spent all day cooking.
02 -
  • Don't skip the resting time after baking—I learned this the hard way by diving in too early and watching the whole thing collapse into sauce on my plate.
  • If your cheese sauce breaks and looks grainy, it's usually because the heat was too high or you added cold cheese all at once; keep the heat gentle and stir constantly.
  • The difference between a casserole that holds together and one that falls apart is often about not overcooking the pasta—al dente truly matters here.
03 -
  • Make this the day before, refrigerate unbaked, and bake it straight from cold—add 10 minutes to the baking time and cover loosely with foil if the top starts browning too fast.
  • If you're scaling it up for a big crowd, use a full hotel pan and multiply the ingredients by one and a half; it bakes evenly and feeds twelve without any trouble.
