What is spaghetti squash?
Spaghetti squash is an amazing yellow-orange vegetable that’s almost magical because it looks like a regular squash on the outside but once cooked the flesh inside turns into angel-hair type pasta that is absolutely delicious.

What is great about spaghetti squash is that it’s inexpensive and available in many areas year-round. Not to mention, it is a perfect pasta option for everyone, even those avoiding gluten.
The amazing thing is that once cooked, it’s basically a delicious healthy pasta just waiting for some spices or a marinara sauce to be added.
Methods for cooking
There are a number of different ways you can cook spaghetti squash, and everyone has an opinion on which one is the best way. I definitely have my own preference that I’ll share below.
- Baking whole in oven
- Roasting sliced halves in oven
- Cooking whole in microwave
- Pressure cooking in an Instant Pot
Baking spaghetti squash whole in oven
My favorite way to cook spaghetti squash is to bake it whole in the oven because there is no prep work, no need to lose a finger trying to cut through the raw tough outer layer, and no mess.
Use a sharp knife to slit approximately 6-8 places in the whole spaghetti squash. Do NOT skip this step or the squash may blow up in your oven. Talk about a mess to clean up!
Place on a baking sheet and cook in the oven at 350°F for approximately 45-60 minutes. Cooking time will depend on the size of your squash. Larger squashes require more cooking time.
Once cooked, allow it to cool so it can be handled safely.
Slice the squash in half and remove seeds using a spoon. In my experience, there aren’t usually that many seeds to be removed, so this is quick and easy.
Use a fork to scrape the flesh inside. It will easily come out in spaghetti-type noodles.
Drizzle freshly squeezed lemon juice over noodles, and add a few seasonings such as sea salt, nutritional yeast, garlic powder, parsley flakes, and smoked paprika. Or, add an oil-free marinara sauce or homemade vegan alfredo sauce.

These noodles are also great for layering in vegetable casseroles.
