Ingredients

  • 2 (14 oz) cans diced tomatoes, with juice or 3 cups fresh diced tomatoes with any juice
  • 1 cup finely diced celery
  • 1 cup finely diced carrots
  • 1 cup finely diced onions
  • 1 tsp dried oregano or 1 T fresh oregano
  • 1 T dried basil or 1/4 cup fresh basil
  • 4 cups chicken broth
  • ½ bay leaf (optional)
  • ½ cup flour
  • 1 cup Parmesan cheese
  • 6 Tbsp. butter
  • 2 cups milk, warmed
  • ¾ tsp salt (do less if you don't like much salt)
  • ¼ tsp black pepper

Instructions

CROCKPOT INSTRUCTIONS:

  • Add tomatoes, celery, carrots, onions, oregano, basil, bay leaf and chicken broth to a large slow cooker.
  • Cover and cook on LOW for 5-7 hours, until vegetables are soft.  (If you don’t want a chunky soup, blend it until smooth.  I love using my Immersion Hand Blender to do this!)
  • About 30 minutes before serving prepare a roux by melting butter over low heat and then adding flour. Stir constantly with a whisk for 5-7 minutes. Slowly stir in 1 cup hot soup. Add another 3 cups and stir until smooth.
  • Add all back into the slow cooker. Stir and add the Parmesan cheese, warmed milk, salt and pepper.
  • Cover and cook on LOW for another 30 minutes or so until ready to serve.

STOVE TOP INSTRUCTIONS:

  • Combine first 8 ingredients in large pot. Cook until veggies are soft. Make roux as instructed and add to soup.
