Creamy, cheesy, comforting—and healthy, too—what more could you want from a pasta dish? The original recipe was posted on my blog way back in 2011, and it quickly became one of my most popular recipes. I've now tweaked it slightly (mainly, streamlined the directions and added more flavour to the sauce), and I think it's better than ever. We just can't get enough! If you want a super-fast weeknight option, feel free to use canned butternut squash purée in lieu of the roasted squash.
