How to Make It
- Add tomatoes, celery, carrots, chicken broth, onions, oregano, and basil to your slow cooker.
- {If you want your soup more smooth and less chunky, pulse celery, carrots, and onion in a food processor until very fine. I did this so my veggies were more hidden in the soup.}
- Cover and cook on low for 5-6 hours until flavors are blended and vegetables are soft.
- About 30 minutes before the soup is ready prepare a roux.
- Melt the butter over medium low heat in a skillet and add the ½ cup of flour.
- Whisk together constantly for 5-7 minutes.
- Slowly add 1 cup of soup.
- This will start to form a thick paste.
- Slowly add another 3 cups of warm soup.
- Add this back to the slow cooker.
- Stir in the parmesan cheese, warmed half and half, and salt and pepper.
- Add additional oregano and basil if needed.
- Cover and cook on low for another 30 minutes.
- You can also blend the soup in a blender at the very end to smooth the soup out if you would like.
