How to Make This Saucy Vegan Spaghetti Bake:
- Preheat your oven to 375°F (190°C).
- Make the spaghetti: in a large 4½-quart (4.5 L) casserole dish, combine the spaghetti, tomato sauce, water, tomato paste, onions, garlic, basil, oregano, salt, pepper, and crushed red pepper flakes (if using). Use tongs to mix everything until combined. Cover and bake for 40 minutes, stopping halfway through to stir and make sure the pasta isn’t sticking to the bottom of the pan.
- Make the alfredo sauce: While the spaghetti is baking, melt the vegan butter in a saucepan over medium-high heat. Add the garlic and cook for about 1 minute while stirring. Sprinkle with the flour and stir to make a paste. Cook the flour paste for 1–2 minutes while stirring frequently to cook the flour. Whisk in the plant-based milk, nutritional yeast, salt, basil, onion powder, and pepper. Bring to a simmer and cook until the sauce is nice and thickened, about 5 minutes. remove from the heat.
- After the pasta has baked for the 40 minutes, remove the lid and spread the alfredo sauce over the pasta. return to the oven and bake another 10–15 minutes, until bubbly. Allow the pasta to cool for 10 minutes before serving.

Hey there, huge fan of your blog/website. Any idea if I can do this recipe with already cooked spaghetti/how to approach that? I am trying to get rid of leftovers
Sam Turnbull says
This recipe won't work with already cooked spaghetti. You could enjoy your leftover pasta with vegan bolognese sauce. 🙂
@umami_umeggi says
I love this recipe mainly because any hands off way to make a delicious meal is a yes from me! Thank you so much for developing and sharing it with us.
The flavors meld so well and it is really foolproof! The starch being contained in the baking dish makes the sauce a beautiful texture too. Can’t wait to try the technique with other flavor combos too!
The only future change I would make as a matter of personal preference is either serving the bechamel on top after serving, or going without the bechamel. It looks stunning but once you serve the spaghetti and it naturally mixes in, you can’t taste it much. I’d prefer to use something like milk in the baking process to make it creamy or stirring yoghurt through after rather than adding the step and butter from making bechamel.
Julie says
Made this last week and it was delicious! I didn't have prepared tomato sauce (I'm assuming that means spaghetti sauce?) so I used a 15 oz can of diced tomatoes and a 15 oz can of plain tomato sauce, and only used 3 cups of water. Next time I will mix all the ingredients except the noodles first, and then add the noodles so it's easier to stir together. Overall it's a great recipe!
Sam Turnbull says
So happy you enjoyed it Julie!
Alec Marra says
Hi just wondering will this recipe also work for penne pasta!
Sam Turnbull says
I haven't tried it, but I imagine it will!
Barbara says
Made this for dinner today. It was excellent.!Thanks for another great recipe.
Michelle says
I made this last night and it was a HUGE hit. Another amazing recipe Sam
I used bucatini since that’s all we had so I had to add to the cook time and about another half jar of sauce and it was well worth the extra cook time.
I added some crumbled tofu that I pan seared at the end and even the anti tofu family member loved it! They’re actually going to buy some tofu to replicate it.
Tamar says
I made it, almost to the letter, and it was amazing. Leaving the noodles in the water really does make the dish velvety. Thanks Sam!
sara says
Hi Sam,
Can you explain tomato sauce, please. Do you mean it to be flavored, like a marinara or just pureed tomatoes? I ask because the recipe also calls for garlic, onion, basil etc. I don't want to overkill.
Thanks!
Sara
Court says
Hey this recipe looks amazing as always! But I was wondering if I can add some cooked lentils into this and if so how many cups do you recommend? And shall I do it at the 40 minute point where you re-stir and add in the sauce ? No problem if not. Cheers, hope you’re having a good day
Sam Turnbull says
Hi Court, yes I am sure you can! I haven't tried it so I would start with a cup or less. Hope that helps!
Shannon says
I am definitely making this by the end of the week! It looks absolutely amazing!
Denise says
This looks really good. Can you omit the butter or use something else (non oil) as a substitute?
Sam Turnbull says
The butter and flour mixture is used to make a roux to thicken the sauce. So you could probably do a cornstarch slurry instead. 🙂
Mindy says
This looks really good. I try to only eat whole wheat pasta. Would that need to be cooked longer?
Sam Turnbull says
I haven't tried it but I imagine it should be about the same. Enjoy!
