How To Cook Spaghetti Squash In The Microwave
Here is a step-by-step guide to show you just how easy it is to microwave spaghetti squash. I have photos for each step, including how to cut it in half, how to scoop it out and how to check if it is done too. Next week, I’ll have a delicious new recipe to share with you featuring spaghetti squash.
Shopping For Spaghetti Squash
Spaghetti Squash is harvested in the fall and is a great storing crop. Look for it in the market from the fall through most of the winter. In the spring and summer, look for signs of rot, as it has probably been stored too long.
Spaghetti squash does not ripen further as it is stored like a banana or tomato, nor show obvious signs of ripeness like the smell of a melon or pineapple, instead, they are picked when they are ripe, cured and then put to market. So if you see them, they will be ripe.
To tell if they are high quality choose spaghetti squash that is smooth and firm. Make sure it doesn’t have any rot which first appears like small round spots.
How to Prepare and Cook Spaghetti Squash in The Microwave
Cut the Squash in Half
To soften the spaghetti squash to make it easier to cut in half, you can microwave it whole for 20 to 30 seconds. Carefully cut the squash in half lengthwise with a large chef’s knife. Break it apart at the stem.
Scoop out the Seeds
Open the squash. Inside you’ll see the center cavity is filled with seeds and pulp. You’ll have to scoop that out before cooking the squash. To scoop out the seeds and pulp, use a spoon and scrape down to the hard flesh of the spaghetti squash. This is sort of like cleaning out a pumpkin for a jack o’ lantern.
Don’t be afraid to scrape away all of the thready pulp!
Arrange the Squash in Baking Dish
Place the squash cut side down, in a large microwave safe casserole dish. I used a 9 by 13-inch pyrex lasagna dish. Pour 1 cup tap water over the squash.
Cover and Microwave the Squash
Layer parchment or wax paper over the squash. Then cover with plastic wrap. The parchment or wax paper keeps the plastic from touching the food. The plastic wrap seals in the steam. Microwave the squash until it is done.
How to Tell When Spaghetti Squash is Cooked
Cooking times will vary depending on the size of the squash so how do you know when the spaghetti squash is done?
After the first 5 minutes, carefully press your fingertip into the squash to see if the skin has softened. (Careful it will be hot!)
If the squash is still hard, continue cooking in 5-minute intervals. Smaller squashes will be done more quickly.
Once the skin is soft enough that it gives when you press on it, test to make sure it is fully cooked by removing the plastic and parchment. Then scrape up the strands of squash with a fork. If the strands closest to the shell are still hard, continue microwaving in 2 minute intervals until they are softened.
Note that you don’t want to overcook it, because it will become watery and the threads will be mushy.
