This sauce is deliciously rich and perfect on its own with some pasta. There is also a ton of other dishes that you can use this in such as a sauce for chicken parmesan, sauce for pizza, a sauce for beef meatballs & pasta, and so much more.

I love this recipe as it reduces the amount of jarred food that I need to rely upon, and as I found out, making a marinara sauce is surprisingly easy.

Tweaking the Recipe

There are so many different changes that you can make to a marina sauce. Below I go through just a couple of examples of what you can do to make this sauce more to your liking.

To make this as easy as possible, you’re able to use canned crushed tomatoes. If you want to use fresh tomatoes, then make sure you peel the tomatoes first. Otherwise, you will end up with tomato skins throughout your sauce.

I like leaving the sauce slightly chunky, so I don’t put it through the food processor. However, with that said, you can blitz the sauce if you would like it to be super smooth.

You’re able to use either fresh or dried herbs in this recipe. The quantities I used are for dried herbs, so you may want to double the amount if you’re using fresh herbs. I try to always use fresh, but sometimes it can be difficult to source the ingredients.

You can try adding some additional ingredients to the sauce. For example, Italian sausages, mushrooms, bell peppers, olives, and much more will work fantastically well in this sauce.

I’m always open to more suggestions, so be sure to drop a comment at the bottom of this page with your thoughts.

Cooking Tips

  • If you want a thin sauce, then make sure you use a blender to blitz it. You can use a handheld blender or a standalone. I find using a handheld blender much easier.
  • Some people love to add wine to their marinara sauce, but it’s important to keep in mind that it might not cook as well in a slow cooker. You may find there is a bitter wine aftertaste to the sauce by the end of cooking. If you decide to add the wine, then leave the balsamic vinegar out of the sauce.
  • The sugar isn’t needed, but it does help remove some of the bitterness from the tomatoes.
  • Using the balsamic vinegar helps add a bit more depth to the sauce. It can be left out if you don’t have any or would prefer not to add it.
