Spaghetti squash is a large round squash that forms spaghettilike strands when it’s cooked. Its texture is crisp, its taste is mild, and it can indeed replace spaghetti in the recipe of your choice. This is especially good news if you’re searching for an alternative to pasta, either because you’re allergic to gluten or because you’re seeking a more nutritious landing pad for a delicious sauce.
Spaghetti squash can be steamed, roasted or cooked in the microwave. Whatever method is used, the squash cooks much faster if you start by slicing it in half. But you have to be careful — sawing through its thick skin can be dangerous. Happily, just a few minutes in a microwave will soften up the squash enough to alleviate this danger.
After cooking the squash and halving it, I finish it off in the microwave, which tenderizes it in 17 to 20 minutes rather than the 30 to 45 minutes required when it’s steamed or roasted. By the way, most recipes instruct you to halve the squash lengthwise, but if you halve it crosswise, as in this recipe, you’ll end up with strands that are much longer ... and more spaghettilike.
When the squash has cooled, use a fork to scrape out the strands. Having prepped the squash to this point, you can store it in the refrigerator for a few days until you’re ready to prepare a sauce and finish it, an option you can’t employ with actual pasta that, because of its starch content, turns into a big gummy wad of stuck-together strands. (You can also freeze spaghetti squash.)
After scooping out the squash strands, add them to the creamy goat cheese sauce, then simmer them for 5 minutes while they soak up the flavor. Again, this is something you can’t do with actual spaghetti, which would not only become too soft but also completely absorb all of the sauce if you simmered it at length.
You can pair spaghetti squash with any sauce you would add to regular pasta. Just remember to let the spaghetti squash cook in the sauce — whatever kind it is — for a few minutes before serving.
