Spaghetti Squash Carbonara

This spaghetti squash carbonara is as velvety and creamy as carbonara should be. It’s infused with bacon’s smokiness, and it’s almost too good to be true. Authentic carbonara sauce, as you get in Italy, is made from luscious egg yolks, Parmesan, and black pepper. Leave the cream in the fridge while achieving a luxurious, velvety coating on your spaghetti squash.

If you love the rich, savory flavors of carbonara but want something a little lighter, this spaghetti squash carbonara is such a good option. Tender strands of roasted spaghetti squash get tossed with crispy bacon, egg yolks, parmesan, and black pepper for a creamy, glossy sauce that feels surprisingly close to the real thing.
The sauce stays true to classic carbonara technique — no cream involved. Instead, the richness comes from egg yolks and parmesan, which melt together into a silky sauce that coats every strand of squash beautifully. The spaghetti squash adds a mild sweetness that works really well with the salty bacon and sharp parmesan, while still letting the carbonara flavors shine.
What I love most is that it still feels cozy and satisfying without being overly heavy. A little parsley at the end keeps everything tasting fresh, and the combination of smoky bacon, creamy sauce, and tender squash makes this one of those recipes that’s easy to crave again and again.

This was to die for! Only thing i added was cooked portabello mushrooms on the side in a tiny bit of chicken stock (w/ pepper,salt,red pepper flakes & paprika) and used that liquid to add to the chicken stock that goes into the sauce. It was SO SO GOOD my favorite meal yet!
I’m so happy to hear that the recipe as a hit!
Hi Kristen! This looked amazing and I decided to try this out yesterday. I had a question about step 5, where you mix a teaspoon of bacon grease, cup of chicken stock, and 2 egg yolks – could you share what the intended consistency is?
I don’t have previous experience with carbonara aka I didn’t know what to expect haha. I was confused by the “whisk consistently until sauce thickens” part. My sauce never really thickened, it stayed pretty liquid-y. The end result was pretty good but just wanted to ask for future reference.
Thank you! And I can’t wait to try some of your other recipes!

It should thicken enough to coat the back of a spoon. It will have some weight to it but will still be pourable. If you’d like it thicker, simply add an extra egg yolk. 🙂
So happy to hear you like the recipes here!!
OMG! Kristen, you are a genius! I LOVE carbonara, but never have it because it is such heart attack on a plate, never mind about the thighs….. I can’t believe I never thought of it, but I’m so glad you did! Thank you bella!
