I did the recipe exactly as follows, but found it to be rather bland when all was said and done. I don't know if maybe the recipe called for too much pasta, and not enough cheese sauce, but it felt like I was just eating pasta, broccoli and a hint of cheese.
I had to add another 3/4 c. of milk just to make the sauce wet instead of thick and dry, and after mixing it in with the pasta and broccoli, I ended up needing to add another small handful of parmesan, 1/2 c. cheddar, 1/4 tsp. garlic and some more pepper. Even then, I didn't like it enough to bother making it again, it just made it edible for tonight.
All in all, more than slightly disappointing.
