Method
 

Instructions
  1. Combine crushed tomatoes, diced tomatoes, vegetable broth, chopped onion, minced garlic, dried oregano, and optional sugar in a 6-quart (or larger) slow cooker, then stir well.
  2. Cover and cook on LOW for 6-8 hours, or HIGH for 3-4 hours, until vegetables are tender and flavors are developed.
  3. Blend the soup directly in the slow cooker with an immersion blender, or carefully transfer in batches to a regular blender, until smooth.
  4. Stir in the chopped fresh basil and optional heavy cream, then taste and adjust seasonings with salt and pepper.
  5. Ladle into bowls and serve immediately.

Notes

For a richer soup, don't skip the heavy cream. Adjust seasonings to taste, as individual preferences vary.
