Ingredients

Scale

2 lb boneless, skinless chicken breasts (or thighs)
3 bell peppers (mix of red, yellow, green), sliced into strips
1 large yellow onion, sliced
1 1/2 cups salsa (mild/medium/hot)
2 tbsp lime juice (plus wedges for serving)
1 tbsp chili powder
2 tsp ground cumin
1 tsp smoked paprika (or regular paprika)
1 tsp garlic powder
1/2 tsp onion powder
1/2 tsp dried oregano
1 1/2 tsp kosher salt (start with 1 tsp if your salsa is salty)
1/2 tsp black pepper
1 jalapeño, sliced (optional)
2 tbsp chopped cilantro (optional)
8–12 small tortillas, for serving
Toppings: shredded cheese, sour cream/Greek yogurt, avocado, pico de gallo (optional)

Instructions

1. Slice the bell peppers and onion into even strips.
2. Place the chicken in the slow cooker and sprinkle with chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and pepper.
3. Pour salsa over the chicken, then add the sliced peppers and onions (and jalapeño if using).
4. Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the chicken reaches 165°F and shreds easily.
5. Remove chicken and shred with two forks, or shred directly in the slow cooker.
6. Stir shredded chicken back into the peppers, onions, and sauce until evenly coated.
7. Stir in lime juice and taste; adjust salt or spice if needed.
8. Optional: for browned edges, spread filling on a sheet pan and broil 3–5 minutes.
9. Serve hot in warm tortillas with desired toppings.
10. Store leftovers airtight and reheat gently with a splash of water or broth if needed.

Notes

Chicken thighs stay extra juicy and are more forgiving if your slow cooker runs hot.
Pick a salsa you love—the flavor comes through in the final fajita filling.
For firmer peppers, add peppers and onions during the last 90 minutes on LOW.
If the filling seems watery, cook uncovered on HIGH for 15–25 minutes after shredding, or broil briefly to reduce.
Finish with lime at the end for the brightest flavor (don’t cook the lime juice).
Meal prep idea: serve over rice with black beans and corn for easy fajita bowls.
Kid-friendly: use mild salsa and skip jalapeño; serve with cheese and sour cream.
Spicy version: add chipotle powder or a minced chipotle in adobo for smoky heat.
Leftovers are great in quesadillas, nachos, breakfast scrambles, and salads.
Freeze up to 2 months; thaw overnight in the fridge and reheat gently.
