I made this easy, Instant Pot Vegan Marinara Sauce last night, and even my wife (who hates spaghetti sauce) loved it.   Forget that store-bought stuff, full of oil, preservatives, and who knows what else….

Homemade Marinara Sauce is AMAZING!

I’ve also used it as a Bruschetta, a topping for Baked Potatoes, and it makes a killer homemade Pizza Sauce too.

I see SO many requests in the FB Groups for store-bought, oil-free spaghetti sauces.

I shake my head and say to myself…..make your own!  It’s so EASY!

Not only that:

  • It’s a WHOLE lot cheaper
  • Tastes AMAZING
  • Only uses a few ingredients
  • And now, with an Instant Pot – can be ready in just under an hour.


Perfect for those busy work nights when you really don’t feel like cooking.

I first published the stove-top version of this recipe, Absolutely Divine Fat-Free Marinara Sauce way back in Feb of 2015 and it has consistently been one of my most favorited recipes.

Serve with a side salad and maybe some warm, crusty bread –  with a little smear of my Vegan Corn Butter (throw in some extra garlic) and YUM!  It’s tastes so fancy and elegant, this could easily be a dinner to impress your non-vegan friends.

And don’t forget, a Vegan Parmesan is easy to make too.

Simply throw some raw cashews, nutritional yeast, salt, and garlic powder into a food processor and chop until it becomes a powder, and you have a deliciously cheesey topping – without using a single drop of dairy.  Click on this link Vegan Parmesan for the recipe.

Vegan Marinara Sauce | Brand New Vegan

Add 1/3 cup of chopped onion and 1/3 cup of chopped red bell pepper to your Instant Pot, and set it to LOW SAUTE.  Add a few tablespoons of veggie broth or water so it doesn’t stick and simmer until softened, about 2-3 minutes.

When the veggies soften, and in 2 LARGE cloves of minced garlic, about 1/3 cup of your favorite mushrooms (or a drained, 4oz can), and an entire 6oz can of tomato paste.

Stir well as the tomato paste will want to stick.

When the tomato mixture is mixed really well, turn OFF the heat, and deglaze the bottom of the pan with the red wine.  You can substitute veg broth or water, but red wine gives it a very rich flavor.

Add in the diced tomatoes, water, and spices, stir to combine and attach the lid.

Make sure the lid is SEALED, and set your IP to MANUAL mode, High Pressure, and set the time for 8 minutes.

When it’s done, CAREFULLY release the pressure (I use a Wooden Spoon)  and give the sauce a good stir.  Add salt and pepper to taste.

If you have an immersion blender, you can blend the sauce to whatever consistency you like, or you could take a few cups out and blend in your blender to make it smoother too.  I like my sauce kind of chunky, but it’s totally up to you.

I hope you like this sauce as much as I do, and please feel free to leave those comments or tag me in Instagram with the hashtag #brandnewvegan.
