Spaghetti Squash Alfredo
This Vegan Spaghetti Squash Alfredo is creamy and full of flavor. If you're looking for a delicious, healthy and easy to make weeknight meal, look no further.

We've been going a little alfredo sauce C.R.A.Z.Y. over here this past month. I hope you guys will bear with me. I just can't get enough of this stuff. You feel the same, right?
I take no blame for it. It's 100% the Dreamy Vegan Cauliflower Alfredo‘s fault. If it wasn't so freaking good, I wouldn't want to put it on everything.
It was pretty much screaming at me to use it in this vegan spaghetti squash alfredo. Tender strands of spaghetti-like squash all smothered in the creamiest alfredo sauce ever. Umm … Yes!
This is one serious bowl of creamy comfort food.
It also happens to be one giant boat of vegetables. The spaghetti squash is obviously a vegetable, the tricky sauce is really just come cauliflower disguising itself as alfredo, and the crispy topping is onions. Oh baby, come to mama. You know how I feel about vegetables. Ya, we get along. And when they go all incognito: oh baby, come to mama.

- When the squash is soft, remove it from the oven and turn the oven to broil. Carefully (they will be hot!) use a fork to loosen the strands of spaghetti. Pour the alfredo evenly over each spaghetti squash half then top with the topping.

You’re not just Whisteling Dixie!! This stuff is awesome.!! I invited my meal lovin’ friend over and she was blown away too. I added some sautéed mushrooms after all was blended and that made for a great chewy bite. Also I used Braggs Amino in place of soy.
Thanks so much!!
I’m so happy you liked it as much as I do!!
Talk about the eyes playing a trick on the brain! I looked at your gorgeous photos and was thinking you had a shredded beef topping. Then I was thinking…. that can’t be right – this is vegan! I had to look through your ingredients to realize they’re crispy fried onions! This is genius! And quite frankly, I would take crispy fried onions over shredded beef any day! Beautifully done, Kristen!
Ha ha I love it!
Sometimes I almost tag a recipe as vegan when it has no dairy or eggs, even if it’s a meat dish lol. I (think) I always catch myself in time!
Ohhh this looks so good and I love how unique this recipe is! I actually haven’t ventured out too far into the world of spaghetti squash, but this has me craving it!
I only started experimenting with spaghetti squash last year and totally fell in love with it. I just love how versatile it is. 🙂
Ah! And one squash makes the perfect amount to share with a date 😉 Creamy dreamy delicious bowls!
It totally does! The perfect date dinner. 🙂
