Meatless spaghetti is a staple in our house, and we make it at least every few weeks!

Pretty much everyone that tries it loves it.

You don’t need meat to make spaghetti taste delicious!

Growing up, I remember my mom making spaghetti a lot, at least once a week usually.

I loved pasta night, when we’d fill our plates with steaming hot pasta, yummy sauce, and drown it in Parmesan cheese.

Carbs for life!

I loved spaghetti then, and I love it now.

Not only is spaghetti a staple food, but it’s so affordable!

This is one of my go to meals for that reason.

How to make Meatless Spaghetti

Cook your spaghetti according to package instructions.

While your spaghetti is cooking, chop up the garlic, onion, and mushrooms.

Add the veggies to a large skillet or jumbo cooker along with olive oil, basil, salt and pepper.

Cook over medium high heat, stirring often, until mushrooms release their liquid and it cooks off.

Add in your spaghetti sauce, and stir to heat through.

Serve topped with freshly grated parmesan cheese and red pepper flakes if you like a little heat!

You can buy blocks of parmesan cheese in your grocery store near the other cheeses.

I love grating it myself fresh as the flavor is just so much better than if you buy it already grated.

These mushrooms cooked down a bit, but they were thick cut, so they had that nice “meaty” texture to them still.

Perfect for a meatless substitute!

I also use mushrooms in my vegetarian bolognese sauce.

I’m obsessed with mushrooms and use them in a lot of my recipes.

They are so versatile!

Mushrooms will always be one of my top favorite vegetables to cook with.

I love how economical spaghetti is.

We added some tomato sauce to our leftovers the next day, and we ended up eating this 3 times, so it made 6 meals for less than $15-20.

Now that’s a good deal!

Even if you add more veggies, it is still very affordable.

I sometimes throw in a bell pepper, or squash during the summer.

Whatever I have on hand!

This recipe is easily customizable and you can add in more veggies to your liking.

I also love that my toddler is basically guaranteed to eat it since it’s a form of pasta.

Less dinner time fighting is a win win.

It’s just as good the next day, and makes great leftovers!

I like using whole wheat spaghetti noodles whenever I make it.

You really can’t taste the difference in my opinion and it’s much healthier than normal enriched spaghetti noodles.

One way to mix it up with the leftovers is to make baked spaghetti.

I mix the sauce together with the leftover spaghetti noodles, and place it in a 13 by 9 baking dish.

Stir in any shredded cheese (like mozzarella) you have on hand, or top with slices of provolone cheese (my favorite!)

Bake at 375 degrees for 20 – 30 minutes, until the cheese is melted and spaghetti is crisped on the edges.

Those crispy edges are my favorite part!

Top your spaghetti with freshly grated Parmesan cheese and enjoy!

I’m a little high maintenance, so I love having mine topped with freshly grated parmesan, powdered parmesan, and red pepper flakes.

It’s the magical trio!

So yummy.

Pasta night is the best.

  1. I scaled this recipe down to match what I had and ended up with really something like 2 servings. I also used dried mushrooms (reconstituted) and marinara sauce (not sure what pasta sauce means). It was great and I really enjoyed it. All out of beef! Thanks for the recipe. Note I also used whole wheat spaghetti pasta from my Philips Pasta machine (low on AP). It’s that kind of year right?

  2. This recipe was AWESOME! I stirred a 1/2 cup of pepper Jack cheese into the mixture, then sprinkled more of the pepper Jack cheese along with shredded sharp cheese/baked til cheese melted. Will serve with toasted bread/salad.

    1. So glad you enjoyed the recipe Shauna! I’m not sure about freezing the sauce, but I think it would work, since you would have cooked the mushrooms first. Let me know how it turns out!

    1. We mix the sauce and spaghetti together and reheat it. Usually we bake it in the oven and add some cheese. It works great!
