Ingredients

Chicken Breasts: Choose boneless, skinless chicken breasts for easy cooking and shredding.
Yellow Onion: Adds a sweet, caramelized flavor. Pick a firm, shiny onion.
Bell Peppers: Any color works. They add a sweet, slightly tangy flavor to the soup.
Frozen Corn: A convenient, sweet addition that brings a bit of crunch. Canned corn would work fine too.
Diced Tomatoes: Use canned for convenience; they provide a rich, tangy base. You can use regular diced tomatoes or go for one with diced chilies in it, like Rotel. My favorite to use in this recipe is the fire roasted tomatoes. They add such a good flavor.
Minced Garlic: Essential for that deep, aromatic flavor. Fresh is best, but jarred works too.
Chile Powder: Gives the soup its distinctive warm, spicy flavor. You could also substitute the chile powder with taco seasoning if that's what you have on hand. Just be aware of the salt content. If your seasoning has salt, omit the salt in the recipe and taste it when finished before adding more.
Chipotle Pepper in Adobo Sauce: Adds a delicious smoky heat. Use more for a spicier soup and less for less spicy.
Chicken Broth: The base of your soup. A good quality broth makes all the difference.
Salt & Pepper: Essential seasonings to enhance all the flavors.
Monterey Jack Cheese: Melts beautifully, adding a creamy texture. Freshly shredded is best.
Scallions: For a fresh, slightly sharp bite at the end.
Tortilla Chips: Optional, but they add a fun crunch. Use your favorite kind.
Equipment
- 8-Quart Slow Cooker: Essential for simmering and blending flavors over several hours.
- Ladle: For serving.
- Shredding Forks or Tongs: To shred the chicken easily.
- Alternative: If you don’t have a slow cooker, a large pot on the stove will work, though cooking times may vary.
Instructions
Prepping Your Ingredients: Start by slicing your chicken breasts into smaller pieces - this helps them cook evenly and makes shredding easier later. Slice your yellow onion and bell peppers into strips. No need to be perfect; just aim for similar sizes for even cooking.
Layering in the Slow Cooker: In your slow cooker, begin by adding the chicken pieces. Then layer the onions and bell peppers on top. This order allows the chicken to be directly immersed in the flavorful broth, absorbing more flavors as it cooks.
Adding Flavor: Sprinkle the minced garlic, chile powder, and add the chipotle pepper into the slow cooker. Don't be afraid to adjust these spices to match your taste preferences. If you're sensitive to heat, start with less and you can always add more later.

Pour in Liquids and Season: Gently pour the chicken broth over the ingredients in the slow cooker. This helps distribute the spices evenly. Add the diced tomatoes, including the juice from the can – it adds a nice tangy flavor to your soup. Lastly, season with salt and pepper.

Setting Your Slow Cooker: Stir everything gently to mix. Cover with the lid and set your slow cooker to cook on low for 6-7 hours. The low and slow process is key to tender chicken and well-blended flavors. Avoid opening the lid frequently as it releases heat and can increase cooking time.

Shredding the Chicken: Once cooked, take the chicken out of the slow cooker. Shred it using two forks – it should be tender enough to pull apart easily. This step is crucial as it allows the chicken to better absorb and contribute to the soup's overall flavor.

Final Touches: Return the shredded chicken to the slow cooker. Give it a good stir to mix everything well. This is a good time to taste and adjust seasoning if needed.
Serving: Ladle the soup into bowls. Sprinkle each serving with shredded Monterey Jack cheese and sliced scallions. The cheese adds a creamy texture, and the scallions give a fresh crunch. If you like, serve with tortilla chips on the side or crumbled on top for an extra crunch.


This yummy chicken fajita soup will quickly become a family favorite. While I love a spicy soup, but when I'm making it for my pickier eaters I don't use much chili powder and I leave out the ancho chilies.
Top Tips
Adjust Spices to Taste: Tailor the level of heat to your preference by adjusting the amount of chile powder and chipotle pepper. Start with a smaller amount and taste as you go. Remember, it's easier to add more spice, but you can't take it away once it's in the pot.
Properly Shred the Chicken: After cooking, make sure to shred the chicken thoroughly before adding it back into the soup. Well-shredded chicken absorbs the soup flavors better and improves the overall texture of the dish. Using two forks, shred the chicken while it's still warm for easier handling.

Topping Ideas
Avocado: Slices or cubes of avocado add a creamy texture and a rich, buttery flavor that contrasts nicely with the soup's spiciness.
Sour Cream: A dollop of sour cream on top can help balance the heat and add a cool, tangy element to each bite.
Fresh Cilantro: Chopped cilantro sprinkled on top gives a burst of fresh, herby flavor, enhancing the overall taste profile.
Lime Wedges: Serving with lime wedges allows individuals to squeeze fresh lime juice over their soup, adding a zesty, tangy twist.
Crushed Tortilla Chips: For added crunch and a nod to the fajita inspiration, sprinkle some crushed tortilla chips over the top.
Jalapeños: Fresh or pickled jalapeños provide an extra kick for those who love more heat.
Substitutions
- Chicken Breast Substitute: Try using chicken thighs for a juicier, richer flavor. They are more forgiving and stay moist even after hours of slow cooking.
- Bell Pepper Alternative: If bell peppers aren’t your favorite, you can substitute them with carrots or celery for a different but equally delicious taste and crunch.
- Corn Substitute: Green peas or chopped green beans can replace corn, adding a similar sweetness and texture.
Variations
- Cheese Variation: Swap out Monterey Jack cheese with cheddar or a Mexican cheese blend for a different cheesy experience.
- Spice Level Adjustment: For a milder chicken soup, reduce or omit the chipotle pepper and cut back on the chile powder. Alternatively, for a spicier soup, add more chipotle pepper or a dash of cayenne pepper.
- Broth Change: For a deeper flavor, try using beef broth instead of chicken broth. This will give the soup a richer, more robust taste.

What to Serve With Suggestions

Refrigerator Storage: Keep the soup in an airtight container in the fridge for up to 2-3 days. The flavors will continue to meld and develop.
Freezer Storage: Freeze in a sealed container for up to 3 months. Perfect for having a ready-to-go meal on hand. I suggest freezing in individual servings for easy, single-serve meals. This way, you only thaw what you need.
Reheating: Warm the soup on the stove or in the microwave. If it’s too thick, add a little water or broth to get the right consistency. Add any fresh toppings like cheese and scallions after reheating.
