Why We Love This Chicken Fajita Soup Recipe

Today’s Skinny Chicken Fajita Soup Recipe is a meal you can enjoy all through the winter months, even when you are watching your diet… It offers the same comforting Mexican appeal of classic chicken fajitas, with a unique taste and texture, minus the heavy tortillas.

This healthy chicken soup is low-fat and gluten-free. Its only carbs are high-fiber black beans and brown rice. However, if you want to make a low carb option, just take out the rice.

How to Make Chicken Fajita Soup

  1. Soften the Veggies. In a large pot, sautรฉ chopped bell peppers, onions, and garlic to soften.
  2. Dump and Simmer. Add the whole raw chicken breasts, black beans, diced tomatoes, chicken broth, fajita seasoning packet, and salt. If adding rice, stir it in with additional water. Bring the soup to a boil. Lower the heat, and simmer.
  3. Shred the Chicken. Use tongs to remove the cooked chicken breasts. Allow the soup to continue simmering to cook the rice fully. Allow the chicken to cool briefly, then shred it with two forks.
  4. Combine. Add the shredded chicken to the soup once the rice is tender. Taste, and salt and pepper as needed. (See the recipe card below for more detailed instructions.)

Want to mix things up? Consider stirring in smoked paprika, corn, pinto beans, and/or crushed red pepper flakes into the soup pot a few minutes before serving.

Serving Suggestions

Ladle the zesty soup into large bowls, and add on some toppings! (If that’s your thing.) We love classic taco-type goodies like:

  • Cheese – shredded reduced fat cheddar cheese, pepper jack cheese or a Mexican cheese blend, or crumbled cotija
  • Scallions – sliced
  • Cilantro – roughly chopped
  • Avocado – peeled and sliced or cubed
  • Sour cream – or greek yogurt, low fat
  • Hot sauce – your favorite level of heat
  • Fresh lime juice – fresh squeezed is best
  • Tortilla strips or chips – keep things on the skinny side with reduced fat and low sodium tortilla chips
