Ingredients list
- 2.5 pounds boneless, skinless chicken breasts
- 3 bell peppers (mixed colors), sliced
- 1 large onion, thinly sliced
- 1 cup low-sodium chicken broth
- 3 cloves garlic, minced
- Juice of 1 lime
- 2 teaspoons ground cumin
- 2 teaspoons smoked paprika
- 1 teaspoon chili powder
- 1 teaspoon dried oregano
- 1 teaspoon salt (adjust to taste)
- 1/2 teaspoon black pepper
- 2 tablespoons olive oil
- 8–10 flour or corn tortillas
- Optional toppings: chopped cilantro, sliced avocado, shredded cheese, sour cream, lime wedges
Step-by-step instructions
- Prep the vegetables: Slice the peppers and onion into even strips so they cook uniformly.
- Season the chicken: In a small bowl, mix cumin, smoked paprika, chili powder, oregano, salt, and pepper. Rub the spice mix over both sides of the chicken breasts.
- Layer the slow cooker: Drizzle olive oil into the crockpot, then add the sliced onions and peppers as the base layer. Place seasoned chicken breasts on top.
- Add liquids and garlic: Sprinkle minced garlic over the chicken, pour chicken broth and lime juice around the edges (not directly over the spices), which keeps the seasoning in place.
- Cook low and slow: Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the chicken reaches 165°F and shreds easily with two forks.
- Shred and combine: Remove the chicken, shred with forks, then return it to the crockpot. Stir to combine with the peppers and onions so the juices and spices coat everything.
- Serve: Warm tortillas, pile on the chicken and peppers, and top with cilantro, avocado, cheese, and a squeeze of lime.
Tips for success
- Even cooking: Slice peppers and onions fairly evenly so they soften at the same rate. If you like a bit more bite, add peppers in the last hour of cooking.
- Prevent dryness: Use chicken breasts with a little fat or swap in boneless thighs for juicier results. Pour the broth around the sides to keep seasoning in place and maintain moisture.
- Make it smoky: For a deeper smoke note, add 1/2 teaspoon chipotle powder or use liquid smoke sparingly.
- Beginner-friendly timing: If you’re out most of the day, cook on LOW for 6–7 hours; the chicken will stay tender but check liquid levels and add 1/4 cup broth if it seems dry.
- Serve ideas: Pair these fajitas with a side of corn, a simple slaw, or a warm dessert after — they pair beautifully with slow cooker comfort mains like this crockpot BBQ chicken for a hearty family-style spread.
Possible variations
- Gluten-free: Use certified corn tortillas or gluten-free wraps and ensure all spice blends and broth are labeled gluten-free.
- Vegetarian: Swap chicken for firm tofu or jackfruit; increase cooking time to allow flavors to penetrate or marinate tofu beforehand.
- Streusel twist (creative seasonal idea): Transform leftovers into a savory-sweet bake by combining shredded fajita chicken and peppers in a shallow dish, topping with a buttery cornmeal streusel (cornmeal, butter, little sugar, salt), and baking until golden for a fall-inspired casserole.
- Spicy or mild: Adjust chili powder and add fresh jalapeño for heat, or keep it mild for kids and sensitive palates.
- Soup adaptation: Turn any leftovers into a comforting soup by simmering shredded fajita chicken with broth, corn, and tomatoes — it’s an easy riff similar to a crockpot chicken corn chowder.
Storage recommendations
- Refrigerator: Store cooled leftovers in airtight containers for up to 4 days. Keep tortillas separate for best texture.
- Freezer: Freeze shredded chicken and peppers in sealed freezer bags for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Gently reheat on the stovetop with a splash of broth or in a covered skillet until warmed through. Microwaving works too—cover to retain moisture.
