Instructions
- Prepare the Chicken:
Pat the chicken breasts dry with paper towels. Season both sides generously with garlic powder, chili powder, salt, onion powder, cumin, black pepper, smoked paprika, and oregano. This ensures the flavors penetrate the chicken as it cooks. - Assemble the Crockpot:
Place the seasoned chicken breasts in a large crockpot. Pour the fire-roasted diced tomatoes with green chilies over the top, spreading them evenly to coat the chicken. - Start Cooking:
Cover the crockpot with the lid and cook on low for 5 hours or high for 3 hours. This slow cooking ensures the chicken becomes tender and juicy. - Add Vegetables:
After the initial cooking time, add the sliced bell peppers and onion on top of the chicken. Replace the lid and continue cooking for an additional 45 minutes. The veggies will become tender but retain a slight crunch for texture. - Shred the Chicken:
Use a slotted spoon to remove the chicken from the crockpot and place it on a large cutting board or plate. Shred the chicken using two forks, pulling it into bite-sized pieces. - Combine and Finish:
Return the shredded chicken to the crockpot. Stir in the lime juice, which adds a fresh, zesty flavor that ties the dish together. Mix everything thoroughly so the chicken and veggies are coated in the flavorful juices. - Serve and Enjoy:
Warm the tortillas in a skillet or microwave. Serve the fajitas family-style with bowls of sour cream, guacamole, salsa, and shredded cheese. Let everyone build their own!
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Chicken thighs are slightly fattier, which makes them extra juicy. They work perfectly in this recipe and may even take a bit less time to cook.
Can I make this recipe spicier?
Yes! For added heat, you can include a diced jalapeño pepper or a dash of cayenne pepper in the seasoning mix. Alternatively, serve with spicy salsa or hot sauce.
