Ingredients You Will Need
Just the squash! Could it be any easier?!
How to Bake Spaghetti Squash Whole in the Oven
Traditionally, you would cut spaghetti squash first, then proceed to roasting it. Baking spaghetti squash whole in the oven, though, is a total gamechanger.
Not to mention there is no risking of life and limb involved when slicing through that hard outer shell. Seriously, cooking spaghetti squash whole is the best way! And an easy way!
- Preheat oven to 375 degrees F. Wash the outside of the squash and pat dry.
- Using a paring knife, pierce spaghetti squash about 15 times. Place whole squash on a baking sheet and bake for 45 minutes, turning once.
- Remove from the oven, place on a cutting board and let cool for 20 minutes.
- Wearing an oven mitt, hold the squash and cut lengthwise.
- Scoop out seeds and flesh from inside of the squash, then discard or roast the seeds just like pumpkin seeds. Now let squash cool down for 10 more minutes to let more steam to escape.
- For long spaghetti like strands, use a fork to remove them and put into a bowl. Run a spoon or fork around the inside of the shell to remove remaining squash flesh out.
Recipe Tip
How long should I roast spaghetti squash whole? The actual cooking time will depend on the size of the squash and your oven. I used a medium sized squash. If your squash is smaller, it might be done in as little as 30-40 minutes or larger squashes, up to 60 minutes.
How to Microwave Whole Spaghetti Squash
When you are in a hurry, cook your whole spaghetti squash using this microwave method! It’s similar to baking whole squash, but microwaved spaghetti squash is done in a fraction of the time.
- Using a sharp knife, pierce spaghetti squash about 15 times. Don’t skip this step or you risk your spaghetti squash exploding in the microwave.
- Place the whole spaghetti squash in a microwave safe dish. An 8×8 or 9×9 inch square baking dish fits in most microwave ovens.
- Microwave for 10-12 minutes. You may need a few more minutes depending on the strength of your microwave.
- Your squash is done when you can easily pierce the skin with a knife. Remove to cool.
Recipe Tip
You can also use your microwave to first soften spaghetti squash before cutting it lengthwise. Brush each half with a little olive oil and a sprinkle of salt. Place squash cut-side in a baking dish and continue cooking until done in the oven or microwave.
How to Cook Whole Spaghetti Squash in the Slow Cooker
Whole spaghetti squash in the crockpot is a great hands off method and depending on your time constraints, it can be cooked on high or low.
- Pierce the skin of the squash about 15 times more or less. This allows steam to escape while it slow cooks.
- Place squash in the slow cooker with 1/4 cup of water.
- Cook on low 5-6 hours or high 3-4 hours. The time will depend on the size of your squash.
- Test for doneness by using a knife to pierce the skin. Remove to cool.
How to Test for Doneness?
To test your cooked spaghetti squash for doneness use a knife to pierce the skin. If it pierces easily, your squash is done! If there is resistance, you will need to cook your squash a little longer.
What Direction Should I Cut My Squash?
There are two different methods to slice your baked whole spaghetti squash.
Using sharp paring knife you can cut your spaghetti squash crosswise through the middle if you like long spaghetti-like strands. This is perfect if you plan to use the long strands as a spaghetti pasta substitute!
Cut your squash lengthwise if you need shorter spaghetti squash strands for a recipe, or if you are making ‘boats’. This is my preferred method.
How to Use It?

FAQs
Yes! Spaghetti squash is great for meal prep as you can store it in the refrigerator in an airtight container up to 5 days. If you find water has pooled at the bottom of your storage container, drain it. Then proceed with sauteeing it to remove excess moisture or using in a recipe.
It really is up to personal preference! Whether your squash noodles are soft or slightly crunchy, both are edible. If you plan to use your noodles in a casserole, slightly crunchy might actually be better as you are cooking the squash again.
You can store raw squash for up to 3 months in a cool dry place. Always check before using! It is has soft spots or brown spots, it has gone bad and you will need to discard it.

I tried to cut it but gave up after 1/2 hours then saw you could bake it whole. Plan to use 1/2 but how do I freeze the rest.
I don’t recommend to freeze it. It’s going to be very soggy after thawing but if you want you can try. Shred into noodles and freeze in an airtight container.
We love this squash, but seldom have it because it is so labor intense. I have severe arthritis in my hand. Today my 91 yr old father took it out to the garage, and brought it back splint in two. He told me it wasn’t too hard to do. I think it boosted his ego. I had only asked him to put ten or twelve holes in it, planning to cook it whole.
Lol your comment made my day. He probably used a chainsaw or a table saw haha. Enjoy!
I LOVE this tip !!!!
I am always so nervous cutting a spaghetti squash ! This will definitely make the job easier and much less dangerous. Thank you for sharing !
Do you think that I could use this technique for butternut squash?
Hi Beth. Yes, for sure, in fact I am working on this post. For whole butternut squash just poke it randomly with a knife and bake at 425 degrees F for 60-70 minutes. I did it yesterday and it peeled so nicely! So easy!
