Spaghetti squash and vegetable soup is a hearty, wholesome dish that combines the mild sweetness of roasted spaghetti squash with a variety of vibrant, tender vegetables. It’s a comforting, yet light soup that’s perfect for cooler weather or anytime you crave something nourishing without feeling overly heavy. The texture of spaghetti squash in soup adds a unique twist, offering slight strands of squash that resemble noodles, making each bite feel both satisfying and refreshing.
To start, the spaghetti squash is roasted to perfection, which brings out its natural sweetness and makes it easier to separate into its signature spaghetti-like strands. Once roasted, the squash is scooped out and added to the soup along with a mixture of vegetables like carrots, celery, zucchini, and bell peppers. These vegetables not only provide a colorful medley but also a great depth of flavor when simmered in broth.
The base of the soup is typically a vegetable or chicken broth, flavored with garlic, onions, and herbs like thyme, rosemary, or bay leaves. The broth brings everything together, creating a fragrant and flavorful liquid that complements the subtle sweetness of the squash and the savory vegetables. A squeeze of lemon or a dash of vinegar at the end helps brighten the whole dish, adding a little zing to balance out the earthiness.
You can easily customize this soup to suit your tastes or what’s in your fridge. Add leafy greens like spinach or kale for extra nutrients, toss in some beans or lentils for protein, or top it with a sprinkle of grated Parmesan for added richness. The beauty of this soup is in its versatility, making it a great option for any season and adaptable to whatever vegetables you have on hand.
Spaghetti squash and vegetable soup is a feel-good meal that’s light yet filling. Whether served as a main or a side dish, it’s packed with fiber, vitamins, and antioxidants. It’s a wonderful way to enjoy the seasonal flavors of squash while keeping things fresh and nourishing, and the light broth keeps it from feeling too heavy. You’ll want to make this soup again and again, as it’s both comforting and good for you, without ever feeling like a typical winter stew.

Ingredients
- 1 spaghetti squash medium
- 1 tbsp olive oil
- 1 onion chopped
- 2 carrots chopped
- 2 stalks celery chopped
- 2 cloves garlic minced
- 1 zucchini chopped
- 1 yellow squash chopped
- 4 cups vegetable broth

- Cut the spaghetti squash in half lengthwise and scoop out the seeds.
- Place the squash halves cut side down on a baking sheet lined with parchment paper or aluminum foil.
- Bake for 30-35 minutes, or until the squash is tender and the strands easily separate with a fork.

I wasn’t sure about using spaghetti squash, but wow, it’s tasty! I might actually make this again!
I totally agree! Spaghetti squash is so versatile. I was skeptical too at first, but now I’m a fan!
This is a total game changer! Perfect for fall, and it’s healthy. Thanks for sharing! 🌟
Absolutely! Love that it’s healthy and so delish! Perfect for cozy nights! 🍂
Uhhh is spaghetti squash pasta? It sounds confusing. Anyway, I used regular pasta instead and it turned out fine.
Did not like it. The flavors did not mix well. Maybe too much garlic? Not for me.
I dunno, too much garlic seems like a small issue. Soup is all about flavors mixing, so maybe it’s just not your thing. 🤷♂️
I actually loved it! The garlic gave it a nice kick. Maybe you can reduce it next time? Everyone has different tastes.
Not bad, but I think it needs more salt and some spice.
This soup was amazing! So flavorful and filling!
I tried it but felt it was missing something… maybe more salt? The spaghetti squash was weird too.
I’m so glad you enjoyed it! This soup really is a hidden gem. Did you add any extra spices?
I made this for my family and they loved it. Super easy to make, will definitely do again!
That’s awesome! I love easy recipes. What else do you make for them?
Sounds good, but aren’t spaghetti squash a bit bland? I wouldn’t know, never tried.
Wow! This soup is so delicious! The spaghetti squash adds such a nice texture. Will definitely make again!
I dunno about this. Spaghetti squash in soup? Seems weird to me. 😕
Tasted really fresh, but I’m not sure I would have thought of putting squash in soup. Unique!
I was skeptical at first too, but it’s a game changer! The squash adds so much to the flavor. You should definitely try it more often.
Tasty soup, but I think it’s missing something. Maybe chili flakes? Just a thought.
This soup was amazing! I loved the spaghetti squash in it. So tasty and healthy!
I dunno, sounds kinda weird to me. Squash in soup? Is that normal?
Totally agree! The spaghetti squash adds a unique texture. I’ve made this like three times already!
This soup is amazing! I added a bit of chili flakes for some heat. So good!
Chili flakes? Really? Seems like a weird choice for a soup like this. But hey, whatever works for ya!
I totally agree! The chili flakes really do add a nice kick! Can’t wait to try it with the squash.
Omg love this recipe! Perfect for winter nights! ❤️
Yum!! Perfect for my diet. Will make again, I swear!
Great idea! Just a suggestion, throw in some spinach next time for extra nutrients!
Easy to follow but it took me forever to bake that squash! Not sure if worth it.
Spaghetti squash? Weird… but I tried it! At least it was easy to make. Not my favorite though.
I loved it! Spaghetti squash is so unique and makes a nice change from pasta. 😊
Honestly, this is the best soup I have ever had! My kids loved it too 🤩
This dish is too healthy for me. I prefer my soups creamy.
Nah, I think this soup is actually good without the cream. Healthy stuff is nice sometimes!
I get it! Creamy is definitely yummier. Maybe add some cream to this soup? It could work!
Soup’s fine, but I forgot the parmesan cheese….. what a disaster! Always adds more flavor.
I don’t know… spaghetti squash? Sounds kinda gross to me. But I’ll give it a try, I guess.
I was skeptical about using spaghetti squash, but it turned out great. Just the right amount of spices. Will make again for sure!
I’m glad to hear you liked it! Spaghetti squash can be tricky, but once you get the hang of it, it’s so worth it.
I tried it too, but I didn’t think it had enough flavor. Maybe I missed something? 🤔
Yummy! I put bacon in mine. Big fan of that combo! Bacon makes everything better!
Bacon? In soup? That’s a no-go for me. But to each their own! 🤷♂️
Uhh, why do we even need spaghetti squash in soup? Seems weird to me.
I think spaghetti squash adds a unique texture! It’s not weird, just different. 🍲
This soup is amazing! So hearty and delicious. I added some extra garlic because I love it!
I left out the zucchini and added potatoes instead because I was out! Still good.
Can someone explain why this is called spaghetti? There’s no pasta!
Didn’t turn out like the picture. Maybe I cooked it too long? Not sure. 😩
So easy to make! My kids even liked it!
YUM!!! 🥳 My family loved it, even my picky kids. This is a winner!
I don’t like squash, so I didn’t think this would be good for me. It’s better than I thought, but not my favorite.
I get it, squash isn’t for everyone! But maybe try mixing it with something you like next time? Could change your mind!
I forgot the garlic… still tasted fine. I guess.
It was okay, nothing special. My kids didn’t eat it, so that says a lot. Maybe I need to add more cheese?
Honestly, kind of bland. I expected more flavor. Maybe I needed more seasoning?
is this even soup? it feels more like…slop. 😬
I actually think it’s delicious! It’s a different take on soup, but I love it! 😋
I skipped the tomatoes because I am allergic. Still tasted fine. Thanks for the recipe!
I didn’t have zucchini so I used bell peppers instead, still turned out great!
Is it suppose to be chunky? Mine came out like a mushy mess. Maybe I overcooked? 🤔
