Instructions
Place the tomatoes, celery, carrots, onion, Italian seasoning, and broth in a 5 qt. slow cooker. Cover and cook on LOW for 6-8 hours.
If you prefer a smoother soup, use an immersion blender or regular blender to process the soup (in batches, if necessary) until smooth. (If you used a regular blender, return the mixture back to the slow cooker.)
About 30-45 minutes before serving, melt the butter in a saucepan over low heat. Whisk in the flour, stirring constantly. Slowly add the half & half, whisking constantly. Cook mixture until smooth and thoroughly combined. Remove from the heat and add the Parmesan cheese. Stir until melted. Add this mixture to the slow cooker and stir well. Cover the slow cooker and continue to cook for an additional 30 minutes.
