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.

Deb says
I don't understand how this can be vegan when using regular egg noodles. Am I missing something?
Sam Turnbull @ It Doesn't Taste Like Chicken says
Hi Deb, the recipe doesn't call for egg noodles. It calls for spaghetti. If you check the ingredients on almost any dried spaghetti box you will see that it almost always has only one ingredient, flour. So almost all dried pasta is completely vegan by default. Egg noodles of course contain egg, and some fresh pastas contain egg, but you are generallys safe with dried pasta. I hope that helps!
Tracey says
This was realllly good. I swapped some raw sunflower seeds and water in place of vegan butter to make it oil free. (Used vitamix to whiz up the sauce)
Soooo yummy.
