Vegetarian Spaghetti Sauce being twirled on a fork.

Vegetarian Spaghetti

Quick and easy Vegetarian Spaghetti is an insanely delicious take on the traditional meat version. We ditch the meat in our vegetarian spaghetti to create a smooth and flavor sauce that that makes the perfect weeknight meal.

Tips and Tricks for Vegetarian Spaghetti

  • Ditch the dairy - to make this dairy-free or vegan, use a vegan parmesan. We love the Follow Your Heart Brand.
  • Spice it up - If you love a particular spice, add it into the sauce when you are making. We like adding oregano and red pepper flakes, but you can add in fresh or dried basil or any other spice you love.
  • Add Vegetables - you can add in some finely chopped and sauteed vegetables to the sauce such as carrot and celery. Not only will it add flavor but it will add a wonderful texture to this vegetarian spaghetti!
  • More Protein - if you would like to add more protein, we suggest added in a sauteed meat substitute like Beyond Meat or Impossible Burger. You can also add cooked lentils.
  • Worcestershire - If you truly want this to be totally vegetarian make sure that you use a "vegan" labeled Worcestershire sauce. If not, it will contain a fish product. Likewise if you are gluten-free, you need to buy a specific gluten free Worcestershire sauce. Generally, I have found that the vegan ones are also gluten-free, but always check the labels!
