Easy Crock Pot Tomato Sauce

Easy Crock Pot Tomato Sauce.  Tomato Sauce is a lot like ketchup and BBQ Sauce, in the fact that you can’t seem to find a store bought kind that doesn’t contain processed sugar.

So, I set out to create a super easy, crock pot tomato sauce that tastes great with no added sugar.  When we got our co-op basket this past week, I saw a package of tomatoes on the vine and I knew I was going to use them for sauce.

This crock pot tomato sauce recipe is almost as easy as my Homemade Vegetable Stock.


Easy Crock Pot Tomato Sauce

This sauce is so easy that you really just throw everything in the crock pot and walk away.  Plus, it makes a ton.  We freeze it for those busy days when you need to make dinner in a hurry.

You can pull it out in the morning and let it defrost on your counter top all day.

  • 10 basil leaves

  • salt and pepper to taste


  1. Throw everything in the crock pot and cook on high for at least 3 hours.


Recipe Notes

I like to cook it longer because the longer it cooks, the more developed the flavor gets. If the sauce seems thin to you, you can thicken it with a tablespoon of arrowroot. You can also uncover and let it reduce while cooking. This sauce would also make a great sauce for my Rustic Vegan Pizza . If you like a super smooth sauce, feel free to blend it with an immersion blender.
