Since we had an overabundance of spaghetti squash in our garden this year, I’ve been trying to come up with new recipe ideas that will utilize this delicious and flavorful winter squash.

Even if you don’t grow your own, since spaghetti squash is widely available in most grocery stores this time of year, I urge you to pick a few up and make this squash soup recipe. You’ll be glad you did!

The ingredient list:

  • Spaghetti Squash (2 small or one large)
  • Italian Sausage (optional)
  • Grapeseed Oil (or other light oil)
  • Onion
  • Zucchini
  • Garlic
  • Canned Tomatoes
  • Chicken, Turkey, or Vegetable Stock or broth (homemade or store-bought)
  • Dried Basil
  • Dried Oregano
  • Red Pepper Flakes
  • Butter
  • Apple Cider Vinegar
  • Salt and Pepper
  • Parmesan Cheese

Can this squash soup be made without the sausage?

Yes! Most definitely!!

This winter squash soup can easily be made with or without the meat depending on what your family enjoys.

My husband happens to love Italian sausage, so I made sure to add it to the soup pot.

However, I would have been just as happy with my soup with veggies and broth alone.

Additional ingredient add-in suggestions:

Since you can tailor this fall soup to your tastes and preferences why not think about adding in some leftover Thanksgiving turkey, if you’re lucky enough to have any?

And what about adding a cup or two of leftover stuffing?

That might sound strange suggestion, but I’ll bet the addition of the bread stuffing would be a wonderful addition to this soup and would make it even heartier. And, of course, it would thicken it up just a bit making it more like a winter squash stew.

  • Cooked Chicken
  • Green Bell Pepper
  • Red Bell Pepper
  • Shallots
  • Broccoli
  • Corn
  • Mixed Vegetables
  • Pepperoni
  • Leftover Pork
  • Cooked Potato
  • Green Beans
  • Butternut Squash
  • Mushrooms

See? That’s the fun of cooking. There aren’t any rules, so it’s okay to play with your food and get creative in the kitchen! It’s actually encouraged, so don’t be scared!

Can spaghetti squash soup be frozen?

YEP!!

Make sure to cool the soup completely, and then add it to a freezer-safe container with a tight-fitting lid.

This soup can be frozen for up to 6 months.

Thaw completely and then reheat on the stovetop.

Can this squash soup recipe be served as a side dish or starter?

It sure can!

Might I suggest serving it as a starter for Thanksgiving this year?

Or, if serving spaghetti squash soup as the main course, why not dish it up alongside this healthy green kale salad with fresh berries and perhaps this roasted garlic cheese bread.

How to make spaghetti squash soup:

  • In a large skillet heat the canola oil over medium heat.
  • Place the spaghetti squash cut side down in the pan and allow to brown (approximately 5 minutes).
  • Remove and continue the same process with the second squash.
  • *Note – This step is optional but the extra browning of the squash will add more flavor to the final soup.

  • Place the browned squash in a microwave-safe dish and cover with plastic wrap, OR preferably a paper plate or paper towels.
  • Microwave until the squash becomes tender and strands will form when the interior of the squash is scraped with a fork.
  • Set aside to cool.
  • When the spaghetti squash is cool enough to handle, scrape the strands of the squash into a large stockpot.
  • Add the oregano, basil, tomatoes, red pepper flakes, salt, black pepper, and chicken stock.
  • Stir well.
  • Meanwhile, in the same skillet in which the spaghetti squash was browned, brown and crumble the Italian sausage (approximately 7-10 minutes) over medium/high heat.
  • Add the onion, zucchini, and garlic.
  • Cook, stirring occasionally until the sausage is no longer pink in the center.
  • Add the sausage mixture to the soup, cover and simmer for 20 minutes.
  • Before serving, stir the butter and apple cider vinegar into the soup and serve hot.
  • Garnish with Parmesan cheese, if desired.

Why add butter and vinegar to this soup?

While it may seem weird to add butter and vinegar to the finished dish, it’s something I’ve been doing lately when cooking soup which makes a very big difference to the end result.

The butter allows the flavor of the soup to linger on the tongue, and the vinegar adds a brightness to the finished soup that is undetectable as vinegar, and yet is subtly noticed and livens up the completed dish.

I do hope you’ll try it!

Why not make this spaghetti squash soup your own? Here’s what Patrick said:

“My one zucchini had gone bad so left that out – Had 9 breakfast sausages so tossed them in (1/4″ bitties) instead of Italian sausage – Used my turkey broth that had a fair bit of turkey cleaned from the bones in it still. Other than that, did the recipe exactly as listed, and WOW! Best soup EVER! Even my wife, who can be pickier than my cat, took some to work for lunch! (yes, the retired cook 😉 – I was a tad worried the squash would be stringy and awkward to eat, but certainly not the case! This is now my favourite soup recipe – and bonus? Have lots of squash left from my garden! Thank you for posting it! PS.. Roasted the seeds too- Yummy, just like you’d said!”

How can I tweak how it is cooked? I have an Instant Pot and would like to use it.

Renée

Hi, Michael! Well, since I didn't make this recipe in the instant pot, that may be a little hard for me to address, but I'll try. If you can brown the cut spaghetti squash in the IP, do so, but if it doesn't fit, don't worry about it and cook it (to soften) in the microwave as the recipe calls for. If you're using the sausage, brown it well in the Instant Pot (along with the zucchini and onion) and then remove once browned. If not using sausage, saute the onion and zucchini alone, omitting the sausage. This will only take about 5 minutes on medium-high. Once the spaghetti squash is cool enough to handle, scrape out the strands and place it, and all the other ingredients (sausage included), into the Instant Pot. Since everything at this point is cooked and all you want to do is meld the flavors, I'd suggest cooking it in the pressure cooker for 10 minutes to combine all the flavors. Add the apple cider vinegar and Parmesan cheese right before serving. I hope this makes sense and answers your question? Please let me know if I can answer anything else for you. Enjoy the soup!

Glad you appreciate that finishing touch. It makes a delicious difference in just about all soups and stews. Enjoy, Wilhelmina!

I just made this soup with a few minor additions. I used homemade turkey meatballs and added a diced carrot and diced broccoli stems. I also added a handful of frozen spinach. Absolutely delicious!

It looks like a very good recipe. But there's one problem: I don't use a microwave oven and don't have one! So what do I do?

Great additions, Jim! I’ll have to try those next time for sure. Love that you made it your own. . Renee
