Spaghetti Carbonara with Butternut Squash is a delicious twist on the classic Italian pasta dish. This version combines the rich, creamy carbonara sauce with the sweetness and earthiness of roasted butternut squash, creating a balanced and flavorful dish. It’s perfect for fall or any time you want a comforting yet slightly lighter take on traditional carbonara.
The traditional carbonara sauce is made with eggs, parmesan cheese, pecorino Romano, and crispy pancetta or bacon. This rich and velvety sauce is tossed with hot pasta, allowing the heat to gently cook the eggs, creating a smooth, creamy coating for the spaghetti. The addition of roasted butternut squash adds a touch of sweetness and a beautiful, vibrant color to the dish. The squash is roasted with olive oil, salt, and pepper until caramelized and tender, which complements the savory carbonara sauce perfectly.
To make this dish, you start by roasting the butternut squash while the pasta is cooking. Once the pasta is done, the pancetta or bacon is crisped up in a pan, and the carbonara sauce is quickly made by combining eggs with grated cheese. The roasted squash is then mixed into the pasta along with the crispy pancetta, and the carbonara sauce is added to create a creamy, indulgent dish.
This version of carbonara retains all the comfort of the original while introducing a new layer of flavor. The butternut squash provides a natural sweetness that balances the salty pancetta and the richness of the creamy sauce. The dish is also easy to customize, add fresh herbs like sage or thyme for extra depth, or use a vegetarian bacon alternative for a meatless version.
Spaghetti Carbonara with Butternut Squash is a perfect fall dish that’s easy to make, comforting, and full of flavor. Whether you’re looking to impress guests or just want a cozy dinner, this dish is sure to satisfy.

Ingredients
- 12 oz spaghetti or pasta of choice
- 1 cup butternut squash peeled and cubed
- 4 egg yolks room temperature
- 1 cup grated Parmesan cheese freshly grated
- 4 oz pancetta cubed
- 2 cloves garlic minced
- 1 tablespoon olive oil
- 1 teaspoon black pepper freshly ground
- to taste salt
Instructions
- Preheat the oven to 400°F (200°C). Toss the butternut squash cubes with olive oil and a pinch of salt. Spread evenly on a baking sheet and roast for 20 minutes or until tender.
- While the squash is roasting, cook the spaghetti according to package instructions. Reserve 1 cup of the pasta cooking water and drain the rest.
- In a large skillet over medium heat, cook the pancetta until crispy. Add the minced garlic and cook for an additional minute.
- In a bowl, whisk together the egg yolks, grated Parmesan cheese, and black pepper.
- Add the roasted squash and cooked spaghetti to the skillet with pancetta. Remove from heat.
- Quickly mix in the egg and cheese mixture, stirring continuously to coat the pasta without scrambling the eggs. Add reserved pasta water as needed to achieve desired creaminess.
- Serve immediately with extra Parmesan and black pepper if desired.
Will try it but not sure if I like squash. Easy step tho, so I hope it turns out good!
Squash? Eww! But hey, maybe it will surprise you. We’ll see!
I was skeptical about squash too, but it’s super tasty in this! Good luck!
Not a fan… the squash felt weird in carbonara. I prefer the classic style. 2/5
Quick and easy recipe! But also kinda hard for me to keep everything from burning, lol.
How can you call this carbonara? Carbonara needs guanciale, not pancetta… 🤔
Yummy! I made it last night and it was a hit. Thanks for the recipe! 😋
This was amazing! The butternut squash really elevates the dish. 5 stars!
I’m not sure about that squash thing. Carbonara is supposed to be simple! Why mess with it?
Totally agree! The squash adds such a nice sweetness. Did you try adding garlic bread on the side? Yummy!
This was surprisingly delicious! The squash added a great sweetness that balanced the savory pancetta. Will make again!
This was absolutely delicious! The butternut squash added a nice sweetness. My family loved it!
Too complicated for a weeknight meal. Takes ages to prepare! 🤦♂️
Honestly, I didn’t think spaghetti should ever have squash. This recipe was a gamble and it paid off big time! Yum!
Very creamy and delicious! I added extra garlic for flavor. Will make again! 😋
Butternut squash in carbonara? That’s a stretch. Not sure if I like it… 1 star.
Yum! I used bacon instead of pancetta and it was still great. 4/5!
Bacon is a good choice! Adds a nice smoky flavor. Glad you liked it!
I dunno, isn’t it supposed to be with pancetta? Sounds kinda wrong to me.
Spaghetti carbonara isn’t supposed to have squash! This isn’t the real recipe. 😠
I didn’t have pancetta, used bacon instead. It turned out fine, but I think it missed something.
I tried this and it took me too long! I’m not a great cook. It came out ok tho, 3 stars.
Meh. I think this would be better without the squash. Just stick to traditional carbonara.
I made this for my family, and they loved it! My kids were skeptics at first, but they cleaned their plates!
That’s awesome! I’m so glad your kids liked it. My family is super picky too, but I’m gonna try this recipe for them. 🤞
Very nice! I just sprinkled some extra garlic on top. Yum! Will make again for sure.
I totally agree! Garlic makes everything better. Glad you enjoyed it!
Just okay. The squash was too mushy for my taste. Maybe it’s just not for me. 🤷♀️
I totally get you! The squash can get mushy. Maybe try it with zucchini next time? 🤔
