Sheet pan mac n cheese means an almost equal ratio of crispy crunchy topping to tender pasta. Is there anything better?

I am not a pasta person, but I do love mac n cheese, and have tried it dozens of ways. Baked, creamy, skipping the pre-boil. It’s almost always good, but my favorite part of the dish is the crunchy topping. The more browned cheesiness, the better, at least in my book. When you fill a deep casserole dish and then top it, you get less topping and more pasta. Not bad, but want more topping?

That’s where sheet pan mac n cheese comes in. It’s my favorite way to make mac n cheese now. The specific recipe doesn’t even matter — although this one is pretty easy and delicious. It’s a basic bechamel cheese sauce with standard cheddar. Nothing fancy. Oh, except the topping. Breadcrumbs are standard, but this time, I used Cheez Its. Yes, those cheesy orange crackers that are everyone’s favorite junk food. Well, at least mine. You can top them with breadcrumbs or tortilla chips or nuts or whatever, but I recommend Cheez Its.

This is a great dish to bring to a holiday meal or potluck, because everyone loves mac n cheese.
