How to Cook Spaghetti Squash in the Oven:

Roasting spaghetti squash is a super simple process. The hardest part is actually slicing the squash into two equal halves (tip: use your sharpest chef’s knife!). Here’s how it’s done:

  • To start, cut your squash in half lengthwise. I’ll reiterate, SHARP chef’s knife and some elbow grease are requirements.
  • Use a spoon to scoop out the seeds and stringy insides. You can either discard the seeds or roast them like you would pumpkin seeds! They make a great crunchy snack.
  • Next, brush the cut sides with olive oil and lightly season with salt. Place the squash halves cut side-down on a rimmed baking sheet coated with foil.
  • Bake at 400°F for around 40 minutes, or until the flesh is fork tender. A good rule of thumb for doneness is if the spaghetti-like strands easily release from the skin. If not, continue baking and check on it every 5 to 10 minutes.

Once the squash is roasted, you’re ready to fill it up! I prefer to eat it right out of the boat instead of dirtying a dish. Plus, edible serving bowls are some of life’s greatest pleasures.

How to Make Vegan Vodka Sauce:

The ingredient lineup in this sauce may surprise you, but I promise it works! A mix of raw cashews, sun-dried tomatoes, nutritional yeast, and lemon juice form the base. Also in the mix is olive oil to smooth it out and black pepper to give it depth. The result is a bright and umami-rich sauce with a “cheesy” edge and crave-worthy creaminess.

Truly, the blind taster would never believe it’s 100% plant-based.

And don’t worry, you do NOT need to soak the cashews overnight. Simply add them to boiling water and let them sit for about 20 minutes. This softens them up just enough to reach their full saucy potential.How to Bake Spaghetti Squash in the Oven

What to Serve with Spaghetti Squash:

The combination of heart-healthy fats and fiber make this dish quite satiating. It also offers a hit of protein from the nutritional yeast, spinach, and mushrooms. However if you’re craving an extra protein source, you could add grilled chicken or shrimp to the squash boats.

I also love enjoying some crusty Italian bread on the side for dipping. (Homemade garlic bread is always a good idea, too.)

Since this recipe is 100% plant-based, it will stay good refrigerated for up to 4 days. I would, however, recommend to scoop the squash strands out of the skin and separate them into Tupperware containers with the sauce. Sprinkle on some fresh basil once you reheat it, and it’s just as good as day one!Vegan and Low-Carb Italian Stuffed Squash DinnerIf you give this recipe a try, be sure to tag #dishingouthealth so I can see your beautiful creations!

    You have some kind of magic with food! Ok, so we made this dish tonight. The words coming out of my husbands mouth are, “This is bonkers, this is magical, oh my god – people that really love food would appreciate being served this. It is interactive ( He likes making the spaghetti in the squash.) he cannot believe it is dairy free! He takes a bite and rolls his eyes in ecstasy.
    I am not kidding with you – as I write this at the table, he has the food on his plate and he keeps walking back to stovetop to take a bite of sauce- which, he already has on his plate. Lol. There is a good chance he will scrape the squash bowl clean and wear it on his head rubbing his belly in happiness!
    Jamie- thank you for sharing this gift of yours!! You have made meal time so much fun!!

    Wow! Super impressed with this. I’m a private chef and needed something vegan for my client and this recipe looked good. So delicious! I used king oyster mushrooms and it was great. Will make again!

    1. Julie says:

      This looks lovely and I plan to try it but I just want to point out that, as it contains no vodka, it is not a vodka sauce. It is actually a palomino sauce.

      1. S says:

        I was wondering about that.
        Does it actually taste like vodka sauce? – from anyone who has made this…?
        Also wondered …the reason for no vodka?

    Thank you for another wonderful recipe! My husband and I both agreed it was the best spaghetti squash dish we’ve had! The only change I made was to use the oil from the sun dried tomatoes instead of olive oil in the sauce- it was so nicely spiced I didn’t want to drain it. We’ll definitely be making this again and again!

    1. Jamie Vespa says:

      Hi Robyn,
      I’m so glad you and your husband enjoyed the recipe!! Thank you for taking the time to leave a review!

    2. S says:

      I would do the same, 😁

  4. Cierra says:

    A great alternative for those with nut allergies, I substituted the cashews for chickpeas. Came out delicious!

        I just made this… and I’m pleasantly surprised! It really taste like vodka sauce. 😁

  5. Kim Bauer says:

    I see that the instructions say to add Vodka but I did not see it on the ingredients list. How much should I put in?

    1. Jamie Vespa says:

      Hi Kim, there’s no actual vodka in the recipe. The recipe states “vodka sauce” in the directions, however it’s referring to the sauce you’re making with the cashews (the “faux” vodka sauce),

  6. Nancy says:

    Hi just wondering if you have a calorie count for this recipe?

      Yum yum it was, and so quick n easy with prepped squash. I will put this one on my menu!

    This was fantastic. I am not a vegan but this looked so good. I could not find the yeast but I’m not sure how it could have made this any better than it already is. I will defiantly make this again and again!!

  8. Carel says:

    It’s intriguing and I may try it, and if so, I’ll let you know. It would satisfy those who are gluten-free and vegan, but those who can’t eat nuts would be out of luck. As for me, a basic vegetarian, I’d jump right on it if indeed had vodka, but I don’t see any.

    1. dishingouthealth says:

      Nope no need for vodka, though feel free to add it!

    2. Erin says:

      is there a different veggie you would suggest adding in place of mushrooms? thanks!

      1. Jamie Vespa says:

        Hi Erin—I love broccoli with this, too!

    For about 5 minutes I was just looking at these appetizing photos of this spaghetti squash dish! And the sauce… I guess, the title surprises everybody. It looks incredibly delicious. I think it tastes just as amazing as it looks at the photos. I have never tried to cook anything like this before. The recipe contains so many ingredients, I wonder how they come together and what the taste will turn out to be. I will definitely keep this recipe and will try to prepare it this weekend. Thank you!
