    How to Make This Saucy Vegan Spaghetti Bake:

    1. Preheat your oven to 375°F (190°C).
    2. 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.
    3. 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.
    4. 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.

    Notes

    Note: I like to make this recipe with a regular wheat pasta. some gluten-free pastas might work as well, but because the cooking times and starch contents vary, the results may differ.
    Make Ahead: I prefer this pasta fresh, but if you have leftovers, allow the dish to cool before covering and storing in the fridge for up to 3 days.

      This is just so perfect and easy! I could watch my toddler in the back yard at the same time I was cooking. We both devoured this! It was perfect with garlic bread. I wish I could attach the picture of her devouring the pasta. We both thought it was delicious! I added a little more garlic than recommended and it was even more perfect.

      I made this with chickpea pasta and reduced the water to 2 cups. I found the pasta cooked so fast that the onions were still crunchy and raw. I’ll make it again, but for other gluten-free cooks, I’d recommend sauteeing the onion first until translucent.

      I made this - sort of - I used chickpea pasta and cooked it in an electric skillet, adjusting quantity and liquid accordingly. I added broccoli florets in the last 10 minutes, and drizzled with some tofu ranch/alfredo I had left over from something else. It went really fast - less than 30 minutes - and was, in a word, DELICIOUS. I will definitely make this again. Many thanks for the idea!

      I have relied on your recipes in the past, but lately you have failed me. This recipe was terrible. It took far longer to cook than the recipe called for. The spaghetti noodles are mushy and tasteless. It was terribly dry. I am trying to save it by adding more Italian seasoning and some no beef broth to moisten it. I am adding granulated garlic to get it to taste like something. I am very, very disappointed in this recipe. I followed it to the letter originally. I really hate to waste food, but if I can't resurrect it, it goes by the wayside. I have been cooking wfpb since 2001 and know a little about recipes. This one just doesn't cut it. Sorry!!

      Love the way this sounds! Just a quick question: what do you mean by prepared tomato sauce? The plain kind, that we would call "passata" in Italy or a sauce like marinara?

        I make a version of baked spaghetti using cooked spaghetti; it is delicious! I cook 12 or 16 oz of spaghetti al dente, drain, and set aside in a mixing bowl or used left over. I saute a diced medium sweet onion with a green pepper chopped small and set aside. While doing the onion and pepper, I pan fry vegan beef crumbles of choice and amount. Then I pour the onion, pepper, and crumbles into my cooked spaghetti, add 1-2 jars of spaghetti sauce (depends on amount of spaghetti) or marinara sauce and toss together. Pour the whole mixture into a baking dish, cover with parchment paper then aluminum foil, and bake for 1 hour at 325 degrees F or until hot in the center. This can even be put together, refrigerated, and baked the next day. I make this a lot for church fellowship meal, everyone loves it and even requests it. This one of Sam's is great for variety and ease. Hugs to Sam for all her hard work. 🙂

      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.

      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!

      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.

      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.

        The butter and flour mixture is used to make a roux to thicken the sauce. So you could probably do a cornstarch slurry instead. 🙂
