What is Marinara Sauce?

Marinara Sauce is a simple tomato sauce with only a handful ingredients.  It starts with tomatoes, then receives a flavor boost from aromatics and seasonings. 

This marinara sauce recipe is the perfect replacement for jarred pasta sauce wherever it is called for in your recipes. It is wonderful served as a dipping sauce and it is even tasty thinned with a bit of broth and served as a soup!

How do you make this marinara sauce recipe from scratch?

Gather the ingredients

You will need 1 (28-ounce) can of diced tomatoes, 1 onion peeled and sliced in half, 4 tablespoons of butter, 1/4 cup raw cashews, and 1 bouillon cube.

Start with a medium sized saucepan.

Place the diced tomatoes and their juices in the sauce pan.

Nestle in the onions…

No need to chop here, just peel and half the onions and nestle them cut side down into the tomatoes.

In no particular order, add the remaining ingredients and season with salt and pepper.

Place the saucepan over medium heat and cover. Cook for 25 minutes stirring 2-3 times.

Remove the onion halves.

You can discard the onion halves at this point if you want, their flavor is in the sauce itself. But, I like to let them cool slightly and chop them. Then I serve them at the table for anyone that wants to add them back into their sauce.

Blending the 5-ingredient marinara sauce recipe

Blend, blend, blend!

Blend the sauce until it is smooth and the cashews have completely incorporated into the sauce with no small bits remaining.

How do you thicken marinara sauce?

Other marinara sauce recipes you may have tried might have seemed a bit thin in consistency, but this marinara sauce is luxuriously rich and velvety thanks to raw cashews!

I use raw cashews all the time in my kitchen in savory recipes like this one! Roasted cashews just simply will not work here, it is important to use raw cashews. The raw cashews absorb the liquids in the sauce and plump as they cook making them easy to blend to a silky smooth consistency.

If you can’t eat raw cashews or just don’t have them you can omit them and the result will be an equally delicious yet thinner marinara sauce. Or you can thicken this marinara sauce recipe by mixing in a slurry.

Ingredients to make 5-ingredient marinara sauce

You can also use a tapioca or arrowroot starch slurry in place of the cashews to thicken this marina sauce recipe.

Simply combine 1 tablespoon starch and 1 tablespoon water in a small bowl. Stir until a smooth paste forms. This is your slurry.

Whisk the slurry into the hot marinara sauce during the last minute of the cook time and simmer for 1 minute. Don’t cook any longer as the starch may break down and the liquid will thin out again.

I do NOT recommend a using a cornstarch slurry because the acid in the tomatoes will cause the cornstarch to lose some of its effectiveness as a thickener. However, if that is what you have on hand it will work in a pinch too. You may just need to adjust the measurements.

1 (28-ounce) can diced tomatoes

1 red onion, halved and peeled 

4 tablespoons butter, divided into quarters 

1 bouillon cube, we use vegan “beef” flavored, but any will work

1/4 cup soaked, drained raw cashews, optional. *** See note***

coarse kosher salt and pepper to taste


In a medium sized saucepan with a tight fitting lid combine the tomatoes, butter, bouillon cube, cashews, and the onion halves cut side down. Season well with salt and pepper. Place the lid on the pan and turn to medium heat for 10 minutes. Stir, replace the lid and cook for another 10 minutes. Stir, replace the lid and cook for 5 minutes more. Remove from the heat and allow to cool slightly before removing the onion halves, discard or chop and serve as a side,  then blend the sauce with either a high speed blender or an immersion blender. 

Serve over pasta or however you would typically use jarred tomato sauce. 


Raw cashews: These are used to thicken the sauce when you blend it. If you don’t have them or have an allergy it is ok to not use them. Simply omit them all together. The sauce will be thinner, but will still be delicious.

Raw cashew substitute: You can use a tapioca or arrowroot starch slurry in place of the cashews to thicken the sauce. Simply combine 1 tablespoon starch and 1 tablespoon water in a small bowl. Stir until a smooth paste forms. This is your slurry.

Whisk the slurry into the hot marinara sauce during the last minute of the cook time and simmer for 1 minute. Don’t cook any longer as the starch may break down and the liquid will thin out again.
