Spaghetti is one of my go-to comfort foods.

We have it pretty often, and love that it makes a ton of food.

This meal makes 6 servings total!

As a kid I’m not sure I was crazy about leftovers, but as an adult I love them!

Less cooking for me.

Any night that we are eating leftovers is a good night for me!

How to Make Vegetarian Spaghetti:

Veggies are key for making meatless spaghetti.

I personally love using mushrooms every time I make a meatless spaghetti sauce, as they have great texture and are really satisfying.

For this recipe I also used bell peppers, onions, and fresh garlic.

I love making my baked spaghetti a bit more wholesome by using whole wheat spaghetti noodles.

You don’t taste the difference, and they are more nutritious than white pasta noodles.

Lastly, for big flavor, we are using freshly grated parmesan cheese.

Grate it yourself and it has so much flavor!

I also use shredded mozzarella cheese which pairs perfectly with the parmesan.

  • 1/2 teaspoon sea salt

  1. Cook spaghetti according to package directions, set aside
  2. Combine onion, garlic, mushrooms, green pepper, olive oil, sea salt, pepper, basil and oregano in a large skillet.
  3. Sautee on medium high heat, stirring frequently for 10-15 minutes, or until mushrooms cook down and evaporate their liquid
  4. Add pasta sauce to veggie mixture and stir to combine
  5. Using a 9 X 13 baking dish, first lay down all of the cooked spaghetti on the bottom
  6. Top spaghetti with 1/2 cup mozzarella and 1 cup of parmesan cheese

  8. Top with remaining 1 cup of mozzarella cheese sprinkled over the top

OH MY GOSH!!!! This is sooooooo yummy. My roomate said he didnt want but "just a little bit" because it dont sound good without meat.....its just the 2 of us, i used 2 jars of prego instead of 1, and baked it a bit longer....dont you know the WHOLE pan is gone!!!!! Hahahaha i was hoping for leftovers to eat on a couple days, but he ate almost ALL of it!!! Lolol. This is sooo very good!! And it was easy to make. Took a bit longer then states and i added more stuff like zuicunni too...this is just amazing!! THANK YOU THANK YOU a million times over for this!!! Now maybe i can start cooking at home.

I am making this right now....its in the oven as i type. I dont have a instagram , so i cant take a picture. I did also as another comment person said and fried some zuicunni in with the mushrooms and onions and green peppers. My only wish is i had fresh basil....im sooooo not a girl whom cooks (my family git these genes haha) and i havent ate meat in 27 years, but to be honest im more of a junk food junkie and eat out every night. Finding this site hopefully will give me other options to stary trying other things because i need to loose weight for health reasons, and this reciepe seemed super easy and quick without a lot of extra stuff i dont have.

I am really eyeing that mushroom lasagna, and a zitti i found on here too. Might see how this goes first.

Thank you very much for sharimg these and making it easy enough to try :)

Will let you know how it goes.

Hi Joy, This looks like the perfect recipe, but I am planning to make this for a large party, and will use 2 9' round casseroles, so will make 1 1/2 times the amounts. I'll be making it the day before and refrigerating it. What temp and how long would you reccomend for just out of the refrigerator? Also I'm thinking I should leave the topping Mozzarella off until the last 15 minutes.? Your thoughts please.. Thank you! Donna in Tacoma Washington

Hi Donna!

I would start with 350 degrees for 25 - 45 minutes. It will depend on your oven, but you will be able to tell it is done when the cheese starts to bubble. I would add the mozzarella in the last 15 minutes like you suggested! To brown the cheese at the end, you could broil for the last 2 - 3 minutes until browned. Just keep a close eye on it!
