Sommer’s Recipe Notes
Why We Love This Chicken Fajita Soup Recipe
I just can’t get enough soup recipes this time of year, and neither can my family. If I made it for them, they would eat it every day. We especially love chicken soups with bold flavors and spices!
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.
Load your bowl of Chicken Fajita Soup with your favorite taco toppings like shredded cheese, sliced scallions and cilantro, and a dollop of sour cream!
Ingredients You Need
- Chicken – boneless and skinless breasts or thighs
- Olive oil – or other high-heat and neutral-flavored cooking oil, like avocado or canola oil
- Bell peppers – seeded and chopped
- Red onion – peeled and chopped
- Garlic – minced
- Black beans – drained
- Fire-roasted diced tomatoes
- Chicken broth – regular or low sodium

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

Ingredients
- 1 pound chicken breasts
- 1 teaspoon olive oil
- 2 bell peppers, seeded and chopped
- 1 red onion, peeled and chopped
- 4 cloves garlic, minced
- 15 ounces black beans (drained)
- 15 ounces fire roasted diced tomatoes
- 8 cups chicken broth
- 1 fajita seasoning packet
- 1/2 cup brown rice, optional
- Possible Garnishes: reduced fat cheese, scallions, avocado
Instructions
- Place a large sauce 6-8 quart pot over medium heat. Add the oil, chopped bell peppers, onions, and garlic. Saute for 3-5 minutes to soften.
- Add whole chicken breasts, black beans, diced tomatoes, chicken broth, 1 fajita seasoning packet, and 1/2 teaspoon salt. If adding rice, stir it in with an additional 2 cups of water. Bring the soup to a boil. Lower the heat, and simmer for 20 minutes.
- Use tongs to remove the cooked chicken breasts. Allow the soup to continue simmering to fully cook the rice, another 10-15 minutes. Allow the chicken to cool for a few minutes, then shred with two forks.
- Once the rice is tender, add the shredded chicken back to the soup. Taste, and salt and pepper as needed.
Does anyone know how many carbs per serving this skinny fajita soup is?
Thank you!
I made this without the rice and without the black beans (and it was delicious even without them!) and also only used one carton of chicken stock and a large can of diced tomatoes. My carb tracker totalled 10g for a pretty hefty size bowl (412g).
This sounds awesome. Have you ever done it in the crockpot?
Hi Chelsea,
You can make it in the crockpot, but you do need to sauté the onions in a skillet first.
I can freeze this, right? Thanks!
Hi Marcela,
Yes, it freezes rather well!
Calories per serving please?
I wondered the same thing too so I went to a recipe calorie calculator and it says this makes 6 servings with each serving being 316 cal!
What calorie calculator did you use? myfitnesspal shows it is 545 calories
This looks great! When I add the chicken, do I add it raw?
Hi Rachel,
Yes, add the chicken raw. It will cook as the soup simmers. :)
Such a bowl of comfort!
LOVE this skinny soup!
