Italian-Style Spaghetti Squash

When cooked and scraped out of the skin, the flesh of this squash looks like strands of spaghetti, which is why it is a popular alternative to pasta.



Ingredient Line: 
2 lb. spaghetti squash, halved lengthwise and seeded
Ingredient Line: 
2 Tbs. olive oil
Ingredient Line: 
1 medium-sized red onion, thinly sliced
Ingredient Line: 
1 zucchini (8 oz.), diced
Ingredient Line: 
4 medium-sized tomatoes, diced
Ingredient Line: 
¼ tsp. salt
Ingredient Line: 
¼ tsp. coarsely ground black pepper
Ingredient Line: 
½ cup reduced-fat grated Parmesan cheese for garnish, optional
Ingredient Line: 
1 small lemon, sliced


  1. Preheat oven to 350 F.
  2. Place squash halves, cut side down, in baking dish. Add 1/4 cup water, and cover dish with foil. Bake for about 30 minutes, or until tender. Remove from oven, and cool slightly.
  3. Meanwhile, heat 1 tablespoon oil in a large skillet over medium-high heat. Add onion, and cook for 3 minutes, or until onion is translucent. Add zucchini, reduce heat to medium, and cook for 4 to 5 minutes, or until zucchini begins to brown. Add tomatoes, salt and pepper. Reduce heat to low, and cook, uncovered, for about 10 minutes.
  4. Using a fork, scrape squash strands into a bowl. Toss with remaining 1 tablespoon of oil. Mound squash in the centers of four pasta bowls. Spoon vegetable mixture around or over squash strands, dividing vegetables equally among bowls. Drizzle with more oil, if desired, and garnish with Parmesan cheese. Add lemon slices, and serve.

Comments on this Recipe

I stuck to the recipe but squeezed a bit of lemon juice on spaghetti strands and added garlic to veggie mixture. Also added fresh basil.

This was a super tasty recipe! Made a few modifications - Cut squash in half and put face down on a small plate w/a little water, microwaved each half separately ~10 min. Used 2 small/med zucchini and cooked them a bit longer than stated, and also added the squash to the veg mix in the saucepan to mix all the juices together, rather than putting mix on top. With tomato liquid, was super moist, savory and delicious!!

superb! i used a can of tomatoes instead of whole tomatoes, some fresh oregano, added a crookneck squash, a big bell pepper, some basil and thyme and at the very end i stuck an immersion blender in and turned half if into a pureed sauce!

This was excellent! Quick and very tasty. I stuck to the recipe fairly religiously. I did microwave the squash (to save time), seeded the tomatoes, skipped the lemon and used more Parmesan cheese. Tossing the squash strands with the veggie mixture made for a more even distribution of flavor, in my opinion. Mixed chicken breast strips with my husband's portion, as this was our main dish. Highly recommended!

Rather than just tossing the spaghetti squash with oil, I decided to mix it with pesto to add a bit of extra flavor. I, too, then tossed the vegetable mixture with the squash rather than serving it on top of it. It turned out delicious. Thanks for the tasty recipe!

This dish was the first time I ever tried Spaghetti Squash and i will def be making it more often. The only thing I did different was add a little bit of vegetable stock after I was done sauteeing all the vegetables, to give the sauce a little more added juice, also instead of sauteeing the tomatoes, I roasted them in the oven, to make them a lil more sweeter, and just added the tomatoes and all the juices back to the sauteed zucchinni mixture, along with some freh basil. Very fresh tasting and delicious dish.

What a yummy, low calorie dish. I added italian seasoning and garlic salt to this very fresh, rustic dish.

Did the recipe just left out the cheese and it was great, even my 11 month old loved it!

Hi mom....this is the recipe i was telling you was very good. I needed to cook the squash way longer then they said though and i added orange peppers and jalepenos to mine.....Yummy

this was amazing! followed suggestions from other comments: used (vegan) chicken broth , added squash to the vegetable mixture, added oregano. great recipe and was very cheap and easy to make!

This could be good!

looks awesome and simple

Let me preface by saying I don't cook with recipes much. How do I measure 2 lb. of squash? Can I go by the weight of the squash when I buy it? Or it's two pounds of the stuff you scrape out of the squash? Same with other recipes that call for things like "2 cups of potato." Do you just eye it? Or cut up the potato and put it in a measuring cup?...

This was very good! Pretty simple to make. I added garlic to mine and italian seasoning. yum. The squash looked so small and I thought a large part of the outer section wouldn't be I bought three...who knew so much squash would come out of that little thing? Froze a lot of squash. They'll come in handy in future dishes. :)

Just made this. Fantastic. Followed recipe, but roasted tomatoes with a little oil olve. Mixed everyhing including squash.

Just made this! Really enjoyed it. I too added garlic and Italian seasoning. In addition I used organic diced tomatoes and half the real tomatoes
