How To Cook Spaghetti Squash – 5 Methods
Learning how to cook spaghetti squash can be a daunting task initially, but with these five easy methods, you’ll be an expert in no time at all!
After the huge success of my guide on how to cook acorn squash, I knew I had to bring you this guide for spaghetti squash. It can be a little more daunting since it’s not like all other squash varieties, so we’re going to go through it step-by-step!
Tip: If you love squash like we do, make sure to also check out my tutorials on butternut squash, kabocha squash, and delicata squash!
My favorite way is also the most labor intensive, which is why I cover all of these different ways. You can make the decision based on what’s best for you today:
- Do you need it to be hands-off and cook slowly in the slow cooker while you work or run errands? The slow cooker method is for you.
- Do you need it done fast? Use your Instant Pot.
- If you have a little more time, try the oven methods!
Also in this post are serving suggestions and storing recommendations. Once you learn how to cook spaghetti squash, you’re going to be making it all the time! As always, if you have any questions, leave them in the comments (I always reply!) or send me an email.
If you try one of these methods, make sure to leave a comment with which one you tried and how it turned out! I’d love to hear how you served it, too. (PS: A star rating is always appreciated!)
Yes, you can. It may be a little tricky, depending on the size of your microwave oven. Cut the squash in half, and place cut side down in a baking dish with about an inch of water.
Microwave on high power for 10-15 minutes, or until soft. Cook time will depend on how large your squash is.
None of the five methods here require peeling the squash, but you probably don’t want to eat the peel as it is quite tough.
Squash is very hard to cut through, so here’s a little tip. Poke some holes in it with a sharp knife (this is to release pressure), and then microwave for 3-5 minutes. Let cool, and then cut. Microwaving the squash softens the peel and makes it easier to slice through.
Unfortunately, overcooked spaghetti squash can be mushy and watery, so keep an eye on it while it’s cooking. You want it to be soft, but not mushy. Some crispness in the strands will lead to a more enjoyable experience.
This is an easy fix! You can return to your preferred cooking method and just cook it a little longer. Five to ten more minutes in the oven might be all it needs. If you were using the pressure cooker method, you could cook it again for 3-5 minutes (remember it will take some time to come to pressure again. If you were using the slow cooker method and don’t want to wait another hour or two, try popping it in the microwave (see above microwave directions), or switch to the baking method.
Five Ways to Cook Spaghetti Squash
Each of these ways is completely effective and has its own pros and cons. My personal favorite is cutting it into rings and baking it. That method prevents the squash from steaming and becoming watery. It yields the pretty, spaghetti-like strands that you see in these photos. This method also allows you to season the squash, which is always a good thing!
As always, the printable instructions can be found if you scroll down to the recipe card!
Baking Spaghetti Squash in Rings
This is my preferred method, provided I have the time and energy to slice the squash into rings.
Pros: This method yields perfect strands of spaghetti squash every time and won’t leave you with soggy “noodles.”
Cons: The prep for this method is more labor intensive and a little trickier, be careful with your knife!
Baking Whole Spaghetti Squash
This method is quite straightforward and arguably the most well-known method of cooking squash.
Pros: It doesn’t get much easier than this!
Cons: The squash steams on the inside, yielding softer, more watery spaghetti squash.
Baking Spaghetti Squash Halves
If I don’t feel like messing with the rings, this is always my next option and the method I use to cook many types of squash.
Pros: Super easy, since there is only one cut to make.
Cons: Slightly soggier squash than with the ring method.
Spaghetti Squash in the Instant Pot
Pros: This is the quickest method and requires very little monitoring.
Cons: Depending on the size of your squash and your pressure cooker, it may not fit. This method also makes the squash very soft, you may find it even falls apart, which makes it harder to get those nice strands of squash out.
A note about this method – I have a 6 quart pressure cooker and my squash was between 3.5 and 4 pounds (if we’re being exact, it was 3.75 pounds). The squash pretty much filled my Instant Pot to capacity, so if you have a 6 quart Instant pot, make sure to keep this in mind when selecting a squash – I wouldn’t go any larger than 3.75 pounds for this cooking method. If you choose a smaller squash, you can decrease cooking time slightly.
Cooking Spaghetti Squash in the Slow Cooker
This method is very similar to using an Instant Pot, but it’s slower…hence the name, slow cooker. You can also cook butternut squash in the slow cooker.
Pros: Set it and forget it! This is a great method if you plan to be gone for the majority of the day. It also doesn’t require cutting a raw squash, which is nice.
Cons: Similar to the Instant Pot, this method will make your squash quite soft and it may fall apart, making it harder to remove the seeds and separate the strands.
Spaghetti squash is a blank slate, just like normal spaghetti! You can try it with an easy turkey bolognese to start, but here are some other fun options:
- Vegan Bolognese
- Spaghetti Sauce with loads of tomatoes and basil, slow simmered on the stove
- Nut-Free Arugula Pesto
- Tomato Cream Sauce
- Chicken, Spinach, and Lemon Cream Sauce
- Skinny Alfredo Sauce
- Chicken Fajita Stuffed Spaghetti Squash (you can replace the chicken with shrimp, steak, taco meat, or black beans)
- Pizza Stuffed Spaghetti Squash (use your favorite pizza toppings)
Cooked spaghetti squash will keep for about a week stored in an airtight container in the refrigerator.

- 1 spaghetti squash
- 1-2 tablespoons olive oil (for oven roasting methods)
- salt and pepper (for oven roasting methods)
To Cook in Rings in Oven:
- Preheat oven to 400°F.
- Scrub squash clean and CAREFULLY cut into 1-inch rings.
- Scrape out seeds
- Spray or rub squash rings with olive oil, sprinkle with salt and pepper and place in a single layer on a parchment-paper lined baking sheet.
- Bake for 40 minutes or until tender. Let cool slightly before using a fork or your hands to form spaghetti squash strands.
To Cook Whole In Oven:
- Preheat oven to 400°F. Scrub the squash clean. Next, use a knife to prick holes all over the squash.
- Place on a baking sheet and roast at 400°F until tender (poke with a knife to test) — about an hour, depending on how large of a squash you have. Turn the squash over halfway through cooking to ensure even cooking.
- When tender, let cool enough to handle. Cut in half – if you cut it lengthwise (from stem to end), you’ll have shorter spaghetti strands. If you cut it crosswise, you'll have longer strands.
- Remove seeds. Use a fork to separate the squash into strands.
To Cook Cut in Half In Oven:
- Preheat oven to 400°F. Scrub the squash clean.
- Cut in half – if you cut it lengthwise (from stem to end), you’ll have shorter spaghetti strands. If you cut it crosswise, you’ll have longer strands. Scoop out the seeds.
- Drizzle inside lightly with olive oil (use a brush or your hands to evenly coat) and sprinkle with salt and pepper.
- Place the squash cut side down on a parchment paper lined baking sheet. Roast at 400°F until tender (poke with a knife to test) — about an hour, depending on how large of a squash you have.
- When tender, let cool enough to handle. Use a fork to separate the squash into strands.
How to Cook Spaghetti Squash in the Instant Pot
- Scrub squash clean and carefully pierce all over with knife (10-15 cuts, 1/2-inch to 1-inch in size).
- Place steamer basket in the bottom of the pressure cooker and add 1 cup water. Place squash in/on steamer basket.
- Secure lid, turn valve to seal, and set for 20 minutes on high pressure. When timer goes off, quick release pressure by turning the valve to "vent."
- Carefully remove squash and let cool enough to handle. Cut in half – if you cut it lengthwise (from stem to end), you’ll have shorter spaghetti strands. If you cut it crosswise, you’ll have longer strands. Remove seeds. Use a fork to separate the squash into strands.
How to Cook Spaghetti Squash in the Slow Cooker
- Scrub squash clean and carefully pierce all over with a knife (10-15 cuts, 1/2-inch to 1-inch in size).
- Place squash in slow cooker and place the cover on. Cook on high for 3-4 hours or on low for 6-8 hours or until easily pierced with a knife.
- Carefully remove squash and let cool slightly. Cut in half – if you cut it lengthwise (from stem to end), you’ll have shorter spaghetti strands. If you cut it crosswise, you’ll have longer strands. Remove seeds.
- Use a fork to separate the squash into strands.
- Cooking and prep times will vary depending on which cooking method is used.
