This recipe is layered with Tex‑Mex flavors thanks to classic fajita veggies, just the right mix of spices, and tender bites of chicken in every spoonful.

Step By Step Instructions
- Prepare the Vegetable Base:
- Add olive oil to a large soup pot or Dutch oven. Once hot over medium heat, add the onions and bell peppers. Cook gently for about five minutes, stirring often, until the veggies start to soften and the onions become translucent. This step is where you build both sweetness and a sturdy foundation for flavor.
- Bloom the Spices and Garlic:
- Add the chopped garlic directly into the softened vegetables. Sprinkle in the kosher salt, a good cracked black pepper, ground cumin, chili powder, and a pinch of cayenne. Stir everything well and let it cook for about one to two minutes. This step allows the spices and garlic to release their essential oils and aroma, making a noticeable difference in taste.
- Add Hearty Ingredients:
- Stir in the refried beans thoroughly with the browned vegetables and spices. This step takes a little patience to ensure there are no lumps. Then, pour in the petite diced tomatoes with their juices, tomato sauce, chicken broth, and frozen corn. Mix well so the beans dissolve evenly into the broth for a creamy background.
- Simmer with Chicken:
- Add the chicken meat to the pot, making sure it is distributed throughout the soup. Bring everything to a gentle simmer and cook uncovered for around twenty minutes. Stir frequently to prevent the beans from catching on the bottom. During this time, flavors deepen and the soup thickens to an almost stew‑like texture.
- Adjust and Serve:
- Taste the soup and fine‑tune the salt or pepper as needed. Spoon into bowls, then finish with a squeeze of fresh lime juice and plenty of cilantro. Add a dollop of sour cream plus crunchy tortilla chips to serve, if you like.

One thing I adore is how refried beans make the broth thick and creamy without needing any dairy. My favorite part is letting everyone pile on toppings around the table while telling their best soup slurping stories.
Storage Tips
Leftovers will keep fresh in a sealed container in the fridge for up to four days. The soup actually tastes even better the next day as the flavors deepen. Reheat on the stove over medium low adding a splash of broth if it has thickened too much.
Ingredient Substitutions
No refried beans Use regular canned beans like pinto or black and mash some for creaminess. Swap rotisserie chicken with poached or leftover roast chicken. If you are out of fresh peppers try frozen or use poblano for a mild smoky variation.
Serving Suggestions
Dish up the soup with a wedge of lime crunchy chips and a generous spoonful of sour cream. A simple green salad or even quesadillas on the side turns it into a full dinner. Try adding avocado slices or shredded cheese to make each bowl feel a little more special.
Cultural or Historical Context
Fajitas started as a humble Texan ranch meal using strips of beef and simple peppers cooked hot and fast. Turning those flavors into soup brings all the bold seasoning and comfort of the original but makes it perfect for feeding a crowd or warming up after a long day.

One day I doubled this and invited neighbors over on a snowy night. The kitchen was cozy and smelled amazing and everyone left asking for the recipe. Now it is my potluck favorite.
