Hearty and full of flavor this Slow Cooker Chicken Soup is simple to make. With a creamy broth base, loaded with vegetables and pesto, this chicken soup is insanely delicious.


  • 4 cups chicken broth
  • 1 - 15 ounce can diced tomatoes
  • 1 - 6 ounce jar pesto
  • 2 large chicken breasts
  • 1 medium yellow onion chopped
  • 1 - 14.5 ounce can cannellini beans
  • 1 ½ cups celery chopped
  • 1 ½ cups carrots sliced
  • 3 tablespoon Italian seasoning
  • 2 teaspoons dried basil
  • 2 teaspoon dried oregano
  • 2 teaspoons salt
  • 1 teaspoon dried parsley

White Sauce


  • Add all ingredients except the white sauce to the slow cooker. Gently stir to combine.
  • Cook on low 6-8 hours or high for 3-4 hours.
  • Once the chicken is completely cooked, remove from the slow cooker and shred or chop into medium sized chunks.
  • Add chicken back to slow cooker and stir to combine. Make white sauce.
  • In a small saucepan melt butter over medium high heat. Once completely melted whisk in flour and continually stir until mixture is bubbly and cook for 2-3 minutes. Slowly whisk in the milk and chicken base.
