Step‑by‑Step Instructions for Chicken Fajita Soup
Step 1: Sauté the Vegetables
In a large 6-8 quart pot, heat 2 tablespoons of olive oil over medium heat. Once shimmering, add 1 cup of chopped bell peppers, 1 cup of sliced red onion, and 3 cloves of minced garlic. Sauté these vibrant vegetables for about 3-5 minutes, until they are softened and fragrant, creating a lively base for your Chicken Fajita Soup.
Step 2: Combine the Ingredients
Add 1.5 pounds of whole boneless skinless chicken breasts to the pot, along with 1 can of black beans (rinsed), 1 can of fire roasted diced tomatoes, 4 cups of chicken broth, and a fajita seasoning packet. If you choose to include 1 cup of brown rice for heartiness, add 2 cups of water to the mixture. Stir well, ensuring everything is evenly combined in the pot.
Step 3: Bring to a Boil
Turn the heat up high and bring the contents of the pot to a full boil, stirring occasionally to prevent sticking. Once boiling, reduce the heat to low and let it simmer. Cover the pot and allow the Chicken Fajita Soup to cook for approximately 20 minutes, ensuring the chicken is cooked through and the flavors meld beautifully.
Step 4: Shred the Chicken
Once the chicken is tender, carefully remove it from the pot and place it on a cutting board. After allowing it to cool for a few minutes, shred the chicken using two forks or your hands. Return the shredded chicken back to the pot, stirring it into the soup to distribute the savory flavors evenly throughout.
Step 5: Finish the Soup
Continue to simmer the Chicken Fajita Soup uncovered for an additional 10-15 minutes, allowing the brown rice to become tender and the broth to thicken slightly. Keep an eye on the soup; it should be bubbling gently, and the rice will absorb the flavors. Taste and adjust the seasoning as needed by adding salt or pepper to suit your preference.

Make Ahead Options
These Chicken Fajita Soup preparations are perfect for busy weeknights, saving you precious time while allowing you to enjoy a comforting meal. You can chop the vegetables and store them in an airtight container in the refrigerator up to 3 days in advance, preventing browning and keeping them fresh. Additionally, cook the soup base (without the rice) and refrigerate it for up to 24 hours before serving. When you’re ready to enjoy, simply reheat the soup on the stove, add the cooked brown rice (or any additional toppings), and simmer until warmed through. Doing this ensures the flavors meld beautifully for a deliciously satisfying bowl of Chicken Fajita Soup with minimal effort!

How do I properly store Chicken Fajita Soup?

It can be stored in the freezer for up to 3 months. To thaw, pop it in the fridge overnight for a slow thaw or use the microwave’s defrost function.
What are some common troubleshooting tips for Chicken Fajita Soup?
If your soup isn’t as zesty as you’d like, adding a pinch of salt or a splash of lime juice can really elevate the flavors. If it turns out too thick, simply stir in a bit more chicken broth or water until you reach your desired consistency. If you did use brown rice and it becomes too soft, next time, consider reducing the cooking time slightly.

For sure! To keep this soup gluten-free, just stick to certified gluten-free broth and fajita seasoning. If you’re looking for a low-carb option, omit the brown rice and black beans.
