This cozy, comfort food favorite has everything you'd hope for in a great macaroni and cheese recipe, plus even more. It's creamy, loaded with flavor, topped with crunchy crumbs, and baked to marry all the flavors and textures. The bonus is the addition of butternut squash and cauliflower to the mac-and-cheese mix. They bring great texture, color, and a nutritional bump to the finished dish without adding much effort to the preparation, and they blend in seamlessly with the other ingredients. To dress up the dish even more, toss a teaspoon of chopped fresh thyme to the toasted panko in Step 2.
