Vegetarian Spaghetti Squash Puttanesca

Vegetarian Spaghetti Squash Puttanesca

This Vegetarian Spaghetti Squash Puttanesca is so delicious!

Are you a fan of olives? How about capers? Well, this dish has both. And what about tomatoes? I am a fan of them all! Now add in some olive oil and garlic and you have a dish that will make your mouth water, seriously!

Let me tell you, the spaghetti squash will fool you.

It’s a great low carb meal because there are no spaghetti noodles here, only vegetables. Spaghetti squash is not like other winter squash. It’s considered to be a non starchy vegetable, like a zucchini or a summer squash. Spaghetti squash is so fun to eat, because it actually resembles spaghetti noodles. If you don’t care for it, you can always substitute the squash for spaghetti noodles. Either way, they will both be delicious.

Have you ever had a traditional Puttanesca sauce? Normally it has anchovies, which I’ve never tried and frankly I don’t plan on it. I think long ago as a child, I made up my mind that anchovies were icky. You know, when someone joked that they were ordering a pizza with anchovies, and we all pretended to puke. I guess it really stuck with me.


This recipe is all vegetarian, just how I like it!

This meal is made with Simple ingredients and healthy too! Lots of garlic, tomatoes, olives, capers and olive oil. This could definitely be a garden to table meal. Just think of the summer months when tomatoes are filling your bowl. With the recent snow, I can’t wait for that!

With this recipe, instead of spaghetti noodles I’m using spaghetti squash. It’s a healthier option, and mainly because I had one just dying to be cooked! I felt like everyday I passed it in the kitchen It was screaming for me to cook it haha. I knew I had to create something. But with limited ingredients I just wasn’t sure what…

Honestly, I thought of a dish I recently had in Palm Springs that blew me away. I’m still thinking about how I’m going to recreate it. To be continued…..But there are parts of that dish I loved. It was the combination of olives and capers, among other things I loved. When I saw some tomatoes on my counter, it was like a light bulb went off in my head. I knew this was the perfect dish to incorporate my squash. And that is how this…Spaghetti Squash Puttanesca was created!


When I made this dish, I was sadly out of parmesan cheese. If you have parmesan, use it! I went shopping later in the day and made sure to pick up a huge chunk of parmesan, and my leftovers tasted so good!!

I think your going to love this dish!

This dish is not only healthy but it’s easy to make. It’s one of those dishes you’ll want to make again and again. Now that you know the back story, let’s get cooking!!!

Cooking time



You’ll be cooking your puttanesca sauce as your spaghetti squash is roasting. If you don’t want to use spaghetti squash you can always use spaghetti noodles.

  • 1 Spaghetti squash

  • Olive oil

  • Salt & pepper

  • Vegetarian Puttanesca sauce
  • 2 Tablespoons or 1/8 cup of capers

  • 2/3 of a cup of Castelvetrano Italian Olives (pitted)- sliced in half

  • 1/3 Cup olive oil

  • 2 Cups of small tomatoes (variety of colors)- sliced in half

  • 1/8 Teaspoon of red pepper flakes

  • Salt & Pepper


  • Roasting your Spaghetti Squash
  • First you’ll want to get your spaghetti squash ready for roasting. Preheat your oven to 400 degrees. Wash and dry your squash. Next cut off both ends of your squash, then cut it in half.
  • Next scoop out the seeds and place in a bowl. Remember the seeds can be used for roasting, or you can save them to plant your own spaghetti squash plant.
  • Now drizzle olive oil in the center and rub the olive oil over your spaghetti squash and make sure the flesh of the squash is covered in oil. Then season with salt and pepper.
  • Next grab a sheet tray, flip your squash over and lay them on the sheet tray and place them in the oven. Cook at 400 degrees for 40 mins.
  • Making your Vegetarian Puttanesca Sauce
  • As your squash cooks, you’ll want to start making your Puttanesca Sauce. First gather all your ingredients.
  • You’ll need to slice your olives, and tomatoes in half. Then set them aside.
  • Next dice your onion. You’ll need 1 small onion or roughly 1/2 a cup. Then set aside.
  • Next you’ll want to slice 4 garlic cloves thinly, and set aside.
  • Now measure your capers and red pepper flakes and set aside.
  • Now your ready to start cooking. Grab a saute pan, add 1/3 of a cup of olive oil. You’ll want to keep your heat on low.
  • Then add your sliced garlic to the olive oil. Make sure to spread them evenly, continue to keep your heat on low. This will help flavor your oil.
  • Next add in your red pepper flakes.
  • Then add in your diced onions and lightly season with salt. Then increase to medium- high heat and saute for 5 mins.
  • Now it’s time to add your sliced tomatoes and saute for 5 mins until they start to soften.
  • Then add in your capers and green olives and warm them through. Taste for seasoning. Don’t add too much salt because the capers and olives are salty already.
  • By now your spaghetti squash should be ready.
  • Let it cool, then use a fork to flake off the strands. They will resemble noodles. Grab a plate and add a pile of your spaghetti squash, then add some puttanesca sauce on top. Next sprinkle on some Parmesan cheese (optional).
