Servings: 8
Calories: 306kcal


  • 2 lbs boneless skinless chicken breasts
  • 1 cup chicken broth (this is to pour over chicken in slow cooker)
  • 1 onion chopped
  • 1 green pepper chopped
  • 3 garlic cloves minced
  • 1 tbsp butter
  • 6 oz cream cheese
  • 2 10 oz cans diced tomatoes with green chilis
  •  cups chicken broth
  • ½ cup heavy whipping cream
  •  tbsp homemade taco seasoning (1 packet of taco seasoning)
  • salt and pepper to taste


  • Cook boneless skinless chicken breasts in a slow cooker for 3 hours on high or 6 hours on low in a cup of chicken broth. Season with salt/pepper.
  • When chicken is cooked through, remove from slow cooker and shred. (You can strain the leftover broth for the soup.)
  • In a large saucepan, saute green pepper, onion, and garlic in 1 tablespoon of butter until they are translucent.
  • With a spoon, mash the cream cheese into the veggies so that it will combine smoothly as it melts.
  • Add the canned tomatoes, chicken broth, heavy whipping cream, and taco seasoning.
  • Simmer on low uncovered for 20 minutes.
  • Add shredded chicken, cover, and simmer for 10 minutes.
  • Add salt and pepper to taste. Enjoy hot!
  • Optional: Top each bowl with shredded cheese, cilantro, green onions, avocado, and/or sour cream.


Options for speeding up this recipe:

  • Option 1: Turn this 3-hour recipe into a 30 minute one by purchasing a rotisserie chicken from the food store. The chicken is already cooked, so all you need to do is cut off the breasts and legs and shred/chop that up to add to your soup!
  • Option 2: Cook shredded chicken in advance in bulkThen portion it out into one pound baggies and freeze them. This way, you can quickly defrost your chicken a few hours or the night prior and have it ready to go the day of! This saves you lots of money, too.
