Ingredients Overview

To create this masterpiece, you need simple, wholesome ingredients that pack a punch. Here is your shopping list:

The Base

• Chicken: 1 lb (450g) boneless, skinless chicken breasts or thighs, cut into bite-sized chunks.
• Rice: 1 cup uncooked long-grain white rice or jasmine rice. (Avoid instant rice as it will turn to mush).
• Broth: 6 cups chicken broth (low sodium is best so you can control the salt).
• Tomatoes: 1 can (15 oz) fire-roasted diced tomatoes (undrained) for that smoky flavor.

The Vegetables

• Bell Peppers: 2 medium bell peppers (any color, but a mix of red and green looks beautiful), sliced or diced.
• Onion: 1 small yellow or white onion, diced.
• Black Beans: 1 can (15 oz) black beans, rinsed and drained.
• Garlic: 3 cloves, minced.

The Flavor & Finish

• Pepper Jack Cheese: 1.5 to 2 cups freshly grated Pepper Jack cheese. This is crucial for the specific flavor profile.
• Fajita Seasoning: A mix of chili powder, cumin, paprika, oregano, onion powder, garlic powder, salt, and cayenne pepper.
• Olive Oil: 1-2 tbsp for sautéing.
• Garnishes: Fresh cilantro, lime wedges, sour cream, and avocado slices.

Step-by-Step Instructions

1. Sauté the Aromatics and Chicken

Heat the olive oil in a large Dutch oven or soup pot over medium-high heat. Add the diced chicken chunks and sear them until they are mostly white on the outside (they don’t need to be fully cooked yet). Add the onions and bell peppers. Sauté for another 4-5 minutes until the veggies soften slightly and the onions become translucent. Add the minced garlic and cook for 30 seconds until fragrant.

2. Toast the Spices

Sprinkle your homemade or store-bought fajita seasoning over the chicken and vegetable mixture. Stir constantly for about 1 minute. Toasting the spices like this “wakes them up” and intensifies the flavor before adding the liquid.

3. Simmer the Soup

Pour in the chicken broth and the can of fire-roasted tomatoes (juices included). Stir well to scrape up any browned bits from the bottom of the pot (that’s where the flavor lives!). Bring the mixture to a boil.

4. Cook the Rice

Once boiling, stir in the uncooked rice and the black beans. Reduce the heat to low, cover the pot with a heavy lid, and let it simmer. Cook for about 15-20 minutes, or until the rice is tender. Stir occasionally to prevent the rice from sticking to the bottom of the pot.

5. The Cheesy Transformation

Once the rice is cooked and the soup has thickened, remove the pot from the heat. This is important—if the heat is too high, the cheese might separate. Gradually stir in the grated Pepper Jack cheese, a handful at a time, stirring constantly until it melts into the broth, creating a creamy, glossy consistency.

6. Serve and Garnish

Taste the soup and adjust salt and pepper if needed. Ladle into deep bowls and top generously with fresh chopped cilantro, a squeeze of fresh lime juice, and maybe a dollop of sour cream or crushed tortilla chips for crunch.

Expert Tips for Success

• Grate Your Own Cheese: Pre-shredded cheese is coated in anti-caking agents (like potato starch) which prevents it from melting smoothly. For that glossy, restaurant-quality finish seen in the photos, buy a block of Pepper Jack and grate it yourself.
• Rice Matters: Use long-grain white rice or Jasmine rice. Brown rice takes much longer to cook and requires more liquid, so if you swap for brown rice, you will need to adjust the broth and simmer time (usually 40+ minutes).
• Leftover Consistency: The rice will continue to absorb liquid as the soup sits in the fridge. When reheating leftovers, you may need to add a splash of water or chicken broth to loosen it back up to a soup consistency.
• Spice Level: Pepper Jack adds a mild kick. If you want it spicier, add a diced jalapeño in step 1 or a pinch of cayenne pepper. If you want it milder for kids, use Monterey Jack cheese instead.

Variations to Try

Creamier Version: If you want an even richer soup, stir in 4 ounces of softened cream cheese along with the Pepper Jack at the end.

Low Carb / Keto Option: Swap the white rice for cauliflower rice. Add the cauliflower rice during the last 5 minutes of cooking instead of the beginning, as it cooks much faster.

Vegetarian Twist: Omit the chicken and use vegetable broth. Add extra beans (like pinto beans or kidney beans) or corn to bulk it up.

Fun Fact: The Origin of Fajitas

Did you know that “fajita” is a Tex-Mex diminutive term for little strips of meat cut from the beef skirt steak? While this soup uses chicken, it honors the spirit of the fajita by incorporating those signature charred vegetable flavors and bold spices, all simplified into a comforting bowl perfect for modern home cooking.

Enjoy this warm, cheesy, spicy delight—it is bound to become a regular in your monthly meal plan!
