  • 2 cloves garlic minced

US Customary - Metric

Instructions

  • In a small bowl, whisk the flour and water.
  • Add canned tomatoes (do not drain), diced tomato, diced onions, and minced garlic to the slow cooker. Pour in flour mixture, chicken broth, tomato paste, butter, 1 cup heavy whipping cream, and garlic powder. Stir to combine. Cover and set the slow cooker to high and cook for 3 hours, or low for 5 hours.
  • Use an immersion blender to blend the soup or place the soup in a blender in batches in a stand blender (be sure lid is on well).
  • Top with shredded parmesan and fresh basil. Swirl ¼ cup of heavy whipping cream into the soup. Enjoy!
  • If you want sausage, brown and crumble it. Stir into the finished soup.

Notes

You can use 5 cups of vegetable broth in substitution for the chicken broth. They are both similar in flavor.
You can make several batches and freeze them in an airtight container or freezer bags to quickly grab for a quick meal. If you choose to keep the leftovers in the refrigerator, they will keep for about three days.
Stove-top Method: Everything can go according to the recipe; however, be sure to use a big pot and set the heating on simmer for about an hour before blending (stirring often); you may need to add additional broth.
