  1. This was a really delicious and simple recipe. I am a novice with squash so wanted something easy to make for my first go round.<br/>I had to microwave my squash for about 5 minutes beforehand to get it soft enough to cut lengthwise, but other than that, it was pretty simple!<br/>I also forgot the basil and it was still delicious!
  2. I really enjoyed this recipe. I usually just nuke spag squash and add butter/parm cheese/garlic salt. I pretty much followed the recipe as stated except for a couple of things. 1. I nuked the squash(used another posters idea of microwaving for 1-2 mins to soften skin 1st before splitting MUCH APPRECIATED IDEA)2. added sundried tomatoes 3. used an 8x8 pan. The only thing I would change is probably adding some broccoli/cauliflower/extra sundried tom's(only used 1 or 2) My DH didn't care for it (he doesn't really like casseroles)but my 2 year old DS liked it
  3. Just way too bland for our tastes Next time, more tomato, more onion, more garlic!
  4. Made this as a "veggie" dinner. Didn't have any fresh tomatoes so I used a quart of my crushed canned tomatoes. Everyone liked this including my picky DS!!!! And that alone makes this a great dish. Thanks for a great way to use spaghetti squash.
  5. 6 thumbs up on this one! The cheeses gave complexity to the dish without overpowering the more subtle flavor of the spaghetti sauce. We'll definitely be making this again!
