  • 1 medium onion chopped
  • 1 tablespoon olive oil
  • 3 bell peppers chopped
  • 3 cloves garlic minced
  • 1 (28 fluid ounce) can fire-roasted diced tomatoes with juices
  • 4 cups chicken broth
  • 1 (14 fluid ounce) can black beans drained
  • 1 (4 fluid ounce) can diced green chilies with juices
  • 1 (1 ounce) packet fajita seasoning (I used Old El Paso)
  • 6 chicken thighs
  • Salt & pepper to taste
  • Serve with (optional): chopped cilantro, Tex Mex cheese blend, lime juice, sour cream/plain Greek yogurt, tortilla strips, etc.


  • Add the oil and onion to a large soup pot over medium-high heat. Sauté the onion for about 7 minutes or until it's lightly browned (that adds more flavor to the soup).
  • Meanwhile, I like to chop the peppers.
  • Add the peppers and garlic to the pot and give it a stir. Cook for about a minute.
  • Add in the diced tomatoes, chicken broth, beans, green chilies, fajita seasoning, and chicken thighs. Increase the heat to high and bring it to a boil. Once it's boiling, reduce the heat and simmer the soup for about 15 minutes.
  • Take the chicken out of the pot and cut it up or shred it with two forks, then add it back into the soup. Season the soup with salt & pepper as needed. Serve soup as-is or add your favorite toppings.


  • If you prefer, use boneless/skinless chicken breasts (I'd use 3 or 4 of them and cook them for about 10-12 minutes, cut them up, return them to the soup, and make sure they're fully cooked).
  • Nutritional information is provided as a courtesy only and should be construed as an estimate rather than a guarantee. Ingredients can vary and Salt & Lavender makes no guarantees to the accuracy of this information. Note: my nutrition calculator didn't have any info for fajita seasoning, so I used the values for taco seasoning instead.
