As a former ho-ho loving, canned food aficionado, I wish I could confirm that, indeed, spaghetti squash tastes exactly like spaghetti.
It does not.
I'm not going to lie to you.
It tastes like a vegetable.
It will not taste like pasta, even if you add cream, butter, or cheese.
(Just as kale chips do not taste like potato chips. Duh.)
Instead, what I'll tell you is the truth: spaghetti squash is a damn good-tasting vegetable. Add a little butter, cream, and some fresh herbs, like thyme, and spaghetti squash makes for a warming, healthful dish.
Cooking spaghetti squash is simple. The question is: do you cook it whole or cut it in half before roasting it? Here are some thoughts on the matter. As the king of convenience, naturally I decided to roast mine whole. I pierced it a few times with a knife, dropped it on a cookie sheet, and placed it in an oven pre-heated to 375 degrees. It took about 55 minutes. It's not like I got off easy. Cutting a hot squash in half and then removing the pulp and seeds was tricky, fingers were burned, swear words were exclaimed. A few seeds got stuck in the "spaghetti." They didn't taste good.
Lesson learned: next time, I'll cut the squash in half, remove the seeds and pulp, and then roast it in the oven.
Squash, it's not pasta, but it's a damn good tasting vegetable.
