I'm going to have to add stars later. I was piddling, and overcooked it, so it was a "tad" dry and hard. It had a nice taste, but I think it would have had a nicer taste had I removed it about 15 min. sooner. I did cook the spaghetti first, and I added the mushrooms into the sauce. When I was taste testing before baking, the sauce was delicious. I would guess that I would rate this 4-5 stars based on my "pre-burn", but I plan on doing it again, and making sure it comes out on time.
This was definitely enjoyed by my whole family. Followed the recipe exactly. The instructions should say "8 ounces cooked spaghetti". I know most people would know that but maybe someone just starting out may not. Easy and great weekday meal!
