  • 6 cups diced tomatoes
  • 1/2 tbsp medium onion, chopped
  • 2-3 tbsp cloves of garlic, minced
  • 1/4 cup fresh basil, chopped
  • 1 teaspoon dried oregano
  • 1-2 teaspoons sea salt
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon ground black pepper
  • 1 tbsp bay leaf
  • 1 teaspoon honey or maple syrup (optional and omit if you are on Whole30)


  • Combine all of the ingredients in the crock pot and cook on low for 6 hours.
  • Once the sauce is done cooking, remove and discard the bay leaf. Using an immersion blender, puree the sauce to a smooth consistency. If the sauce is too thin for your liking, add tapioca starch or arrowroot one tablespoon at a time until the desired consistency is reached. 
  • Allow the sauce to cool completely. Package into air tight containers and store in the fridge for a week or in the freezer for months!


  • This recipe makes about 48 ounces of sauce.
  • This sauce takes just minutes to throw into the slow cooker and then simmers away for hours, blending all the natural flavors and ingredients into one wholesome sauce.
  • Enjoy this crock pot tomato sauce for weeks - without the added sugar or preservatives.
