Vegan Baked Spaghetti

This Vegan Baked Spaghetti is a delicious twist on the classic comfort food! Pasta is twirled into a hearty vegan meat sauce and then baked to cheesy perfection. Feed a big group with this easy family favorite or use it as a make-ahead meal!

This cheesy meatless spaghetti bake is loved by everyone who tries it!

Spaghetti for dinner is definitely something to get really excited about! However, something incredibly magical happens when you take it a step further by popping it into the oven. 

It turns into a sliceable casserole, almost like spaghetti pie, with the delicious saucy flavors baked into every noodle. It's super cheesy and almost like a million dollar spaghetti.

I like to incorporate a quick “meaty” sauce similar to my Cherry Tomato Sauce. Or, you can save time by using your favorite jar of spaghetti sauce.

Plant-based baked spaghetti is such a filling meal and can even be prepped ahead of time! Store it in the refrigerator and simply bake it in the oven before feeding your ravenous group.

Leftovers are just as good the next day!

This homemade spaghetti bake reheats really well in the microwave if you want to eat it throughout the week and it's great for packing into lunch boxes.

Ingredients and Substitutions

• Spaghetti - Use your favorite including gluten-free, wheat, chickpea, etc. Other pastas can work as well such as angel hair, penne, elbow macaroni.
• Olive Oil - I like olive best, but any other works. Use a bit of water for oil-free.
• Onion - Yellow onion gives a lovely subtle flavor, although whatever you have on hand is just fine.
• Garlic - Garlic is a must! Use powdered if you don’t have any fresh garlic.
• Vegan Crumbles - Use plant-based ground “meat” crumbles. I like Impossible, Beyond, or Gardein brands.
• Tomatoes - Use canned diced tomatoes and a jar of your favorite pasta sauce or tomato sauce.
• Seasoning - Feel free to adjust the salt, pepper, Italian seasoning, and crushed red pepper to your taste.
• Dairy Free Cheese - Mozzarella and parmesan are delicious in this pasta but other types of plant based cheese such as cheddar or gouda would be good too!
• Fresh Herbs - Garnish this spaghetti casserole with basil, parsley, or any other fresh herbs.

How to Make Vegan Baked Spaghetti

Here are some quick visual steps. Find the full recipe with exact measurements on the recipe card below.

• Preheat the oven to 375 and grease a large (9x13) oven-safe dish with cooking spray, oil, or vegan butter. This keeps the pasta from sticking to the dish. Dice the onions and mince the garlic.
• Start to boil a large pot of salted water for the pasta. Cook the noodles to al dente according to the package instructions. We don’t want to let the spaghetti become too soft because it will cook further in the oven. 
• Meanwhile, place a large sauté pan over medium heat. Once heated, add the oil and then the onions. Sauté them for 4-5 minutes until they’re slightly translucent. Next, add the garlic and cook it for about a minute.
• Add the vegan ground crumbles to the pan and stir them around to break up the clumps as they heat up and get get a little crispy. 
• Pour in the pasta sauce, diced tomatoes, and seasoning. Stir occasionally as the sauce cooks on a low boil for 5 minutes. 

• Drain the cooked pasta and add it back to the large pot. Then, add 1 cup of the shredded vegan mozzarella and all of the sauce. Stir them together until they are well combined.
• Pour the pasta into the greased dish. Spread the noodles out and then top it with the vegan parmesan and the remaining vegan mozzarella.
• Cover the dish with foil and bake the pasta for about 15 minutes. Then, uncover it and bake it for another 10 minutes for a crispy top. Covering the pasta at first will create steam that will help the vegan cheese melt and keep the pasta from drying out too much.

• Garnish it with fresh herbs and enjoy your spaghetti bake.

You can make it a big fancy meal by serving it with my Broccoli and Beet Salad and Vegan Tiramisu for dessert!

Recipe Variation Ideas

• Stir in some vegan cream cheese or tofu ricotta for a creamy bite.
• Make it spicy with more red pepper flakes, cayenne seasoning, or jalapeños.
• Add vegetables such as diced bell peppers, mushrooms, baby spinach, or zucchini to the sauce.
• Try it with vegan cheddar cheese, ½ teaspoon cumin, and 1 tablespoon taco seasoning for a taco pasta flavor.

No-Waste Ideas

• Make Mexican Pizza or Queso Fundido with remaining vegan ground crumbles.
• Use leftover vegan mozzarella and parmesan to make Creamy Tomato Pasta or Ravioli.

Storage & Reheating

Store leftovers in a covered dish in the refrigerator for 4 days. Reheat the baked spaghetti in the microwave until heated through.
