You know I LOVE spaghetti squash – right? 

I’ve made a few recipes on the blog over the years and you all seem to really dig them! Like my Southwest Taco Stuffed Spaghetti SquashSausage and Peppers Stuffed Spaghetti Squash, Air Fryer Southwest Spaghetti Squash, Buffalo Chicken Stuffed Spaghetti Squash, or my Ground Chicken Fajita Spaghetti Squash.

I mean, what’s not to love about a winter squash that literally shreds like pasta? 

Now, usually, I roast my squash BUT I’m here to share a secret with you today. 


That means cooking spaghetti squash just got even easier!

I used a lot of exclamation points up there. Sorry, I’m basically Elaine Benes. 

How to cook spaghetti squash in the microwave

Listen, all you need is the following:

  • spaghetti squash (obviously)
  • sharp knife
  • 9×13 glass microwave-safe dish
  • water

That’s it! How freaking simple is that?!

I often get asked how to make spaghetti squash so this post has been a long time coming. 

Spaghetti squash cut in half

The first you want to do is cut that spaghetti squash in half.

I’m always relieved when I manage to cut through a squash without chopping my hand off. I seriously wonder what the statistics are on people who lose fingers because they were just trying to cut a squash in half.

I’m betting hundreds. 

If you’re terrified of cutting into the squash, you can stab it all over with a fork (making little vent holes) and put it in the microwave for about 4 minutes. 

This will help soften the outer skin and make it easier to cut through the squash.

After cutting your squash in half, scoop out the seeds and stringy insides. 

I’m betting you could roast those seeds and make a pretty killer snack. 

A few years ago I made sweet salty roasted pumpkin seeds, and now I have a craving to try this with my spaghetti squash seeds. 

I love being able to use all the squash.

After your spaghetti squash is cut in half you put it cut side down into a 9×13 glass pyrex dish.

My microwave is wide enough to fit a dish this size but if you own a smaller microwave you can easily do each half separately in an 8×8 or save the other half for later in the week.  

I love the idea of saving half for later in the week because I can almost never finish a whole squash. 

It’s so good but I’m not that much of a beast.

How long to cook spaghetti squash?

One of the most important steps to making this whole “how to cook spaghetti squash in the microwave” recipe actually works is adding water. 

You’re looking for about 1 inch of water in the dish before it goes into the microwave. 

This helps steam the squash so it turns out soft and delicious. 

My microwave takes about 15 minutes to fully cook but that timing should be adjusted for the size of your squash and the wattage of your microwave.

Also, make sure you don’t run out of water in your pan.

After your squash is ready you just use a fork to shred the inside flesh.

I pull it in from the sides and bottom and it should all come off from the outside shell.

It’s sort of amazing to see it all pull off and just throw away a thin squash shell. 

That’s it. That is how you cook spaghetti squash in the microwave.

And shredding is all you have to do to “make” the squash. 

Easy peasy.

  • Cut your squash in half lengthwise.
  • Scoop out the seeds and stringy insides of the squash.
  • Lay the spaghetti squash, cut side down, into a 9×13 microwave safe glass pan.
  • Pour the water into the dish. You want about an inch of water in the dish so add more if needed.
  • Add squash to the microwave and cook for anywhere from 10-15 minutes depending on the size of the squash and the wattage of the microwave.
  • The squash is ready when it can be easily pierced with a fork and the inside flesh of the squash shreds like noodles.
  • Carefully remove from the pan, shred the inside of the squash with a fork and season with desired amount of kosher salt and black pepper.



  1. Always be careful cutting squash in half as it’s an easy way to lose a finger.
  2. I like to cook my squash for 10 minutes and then test to see the doneness. In my 950watt microwave it takes 15 minutes for a 4 pound squash.
  3. If you microwave cannot hold a 9×13 pan you can cook them separately in an 8×8 pan or save a raw half for the next day.

Save even more time and less risk of injury. Cut the squash across instead of long ways. Just put plastic wrap on the cut end and place cut side down in you microwave. Done in less than 10 min. Depending on size of squash. Skip the dish, skip reassembling it just do the two halves with plastic wrap on the end only. Been doing it this way for every. Easy easy!

It's now close to the end of February. I just realized that I had a spaghetti squash that my sister gave me, last fall. When I cut it, many of the seeds had sprouted. So, using your seed snack idea as a base, I decided to try eating them. They were a little bitter, but less than some celery that I have enjoyed. They were quite good. I think they would be a good thing to add to a salad. So, if a person was into sprouting, I would think that would be another way to use what some others might toss in the garbage.

Trouble is, the 9x13 dish doesn’t fit in my microwave.

Hi Karen! You can break this into 2 steps and use a 9x9 instead.

This microwave recipe for cooking spaghetti squash makes the best I've had! I tried your suggestion to cook only half and cook the remainder fresh on another day. Great idea.

You can also wrap the squash in plastic wrap, after it is cut,seeded and seasoned. Put the halves back together and completely seal in the plastic wrap. About 10 minutes in micro
