Meatless Spaghetti Sauce

Spaghetti is a staple in our house, and we eat it at least once or twice a month.

This recipe is my go to for easy meatless spaghetti sauce.

This recipe is both vegan and vegetarian!

It occurred to me recently that not everyone knows just how easy it is to make spaghetti both meatless and delicious.

Whether you are vegetarian, or just looking for a meatless monday recipe, this spaghetti is for you!

Meatless spaghetti sauce is not only delicious but packed full of veggies.

I’m a big fan of mushrooms, and they are perfect for getting that “meaty” texture in spaghetti sauce.

This recipe is mushroom based for that reason!

Mushrooms are just incredible for substituting meat in recipes.

They are also one of the key ingredients in my vegetarian bolognese recipe.

And a must have when making vegetarian baked spaghetti.

So easy to cook and delicious every time!

How to make spaghetti sauce with no meat

The flavor of fresh garlic and onion add a ton of depth to this recipe, so I start with that as a base.

Add your fresh diced garlic and onion to a large skillet or jumbo cooker.

The pan pictured is called a “jumbo cooker” and I purchased mine from walmart.

It is by far my most used and loved kitchen tool, and I have been buying them for close to 10 years!

If you’re looking for a great all purpose pan that will hold just about any recipe, I highly suggest getting one.

Next, add in your sliced baby bella mushrooms.

These are small and the texture is perfect for meatless substitutes.

I also use chopped up portobello mushrooms (see below.)

Just buy the caps and dice them up into pieces.

The combination of both mushrooms makes for a super chunky and flavorful sauce.

Texture is everything!

Once your garlic, onions, and mushrooms cook down, they will look like this.

Browned and delicious.

That means they are perfect!

Basically, we are looking for two things: the onion to be caramelized, and the mushrooms to have released and cooked out all of their liquid.

The pan should not have a lot of excess liquid left over.

After this is done, pour in a jar of your favorite pasta sauce (I use mushroom flavor because I just love it so much!)

Any flavor of your favorite pasta sauce will work fine.

Stir for a few minutes to heat, and it’s ready to serve!

We love whole wheat noodles around here, but sometimes go for the traditional white.

Either way you cannot go wrong!

This mushroom spaghetti sauce is already vegan, or you can add cheese if you are not vegan.

Freshly grated parmesan cheese will take the flavor to the next level!

My favorite toppings are shredded mozzarella, freshly grated parmesan, and red pepper flakes for a bit of spice.

If you like a little spiciness, red pepper flakes are so good in this dish!

This makes a huge batch and easily serves 5 – 6 adults.

Perfect for leftovers!

Some people don’t like leftovers, but I will always love leftover spaghetti.

It is always so yummy!

We usually eat this leftover two or three times as a family of 3.

The next night I will mix the sauce and noodles and bake it with cheese to make baked spaghetti.

Crispy cheesy edges are the best part of baked spaghetti!

And speaking of baked pasta dishes, this Veggie Lover’s Baked Rigatoni is always a hit too.
