Instructions
Now that you have your ingredients ready, it’s time to put them together and let the slow cooker work its magic. Follow these simple steps, and you’ll have a delicious, flavorful meal ready in no time.
- Prep the Ingredients:
Start by slicing the onion and bell peppers. This is an easy step that adds vibrant color and sweetness to the dish. Place the chicken breasts or thighs at the bottom of your slow cooker. The chicken will cook and soak up all the flavors as it simmers. - Season the Chicken:
Sprinkle the fajita seasoning mix generously over the chicken. Make sure to coat the chicken evenly, ensuring that every bite will be bursting with that zesty, bold flavor. Add the sliced onions and bell peppers on top of the chicken, then drizzle the olive oil over everything to help the flavors meld together. - Add the Liquid:
Pour the chicken broth or water into the slow cooker. The liquid helps to keep the chicken moist and creates a flavorful sauce that combines with the fajita seasoning. Squeeze the juice of one lime over the mixture for a burst of freshness and acidity that balances out the rich flavors. - Slow Cook the Fajitas:
Cover your slow cooker and set it to cook on low for 6-8 hours, or on high for 3-4 hours. The longer you let it cook, the more tender the chicken will become. When done, the chicken should be cooked through and shreddable. - Shred the Chicken:
Once the chicken is cooked, remove it from the slow cooker and use two forks to shred it directly in the pot. This makes it easy to mix the chicken with the veggies and fajita sauce, ensuring every bite is full of flavor. - Serve and Enjoy:
Now that the fajitas are ready, it’s time to serve! You can serve the shredded chicken and veggies on warm tortillas, over rice, or even as a salad topping. Don’t forget your favorite fajita toppings, like guacamole, sour cream, salsa, or fresh cilantro.

- Customize the Veggies: If you’re not a fan of bell peppers or onions, feel free to swap them for other veggies. Zucchini, mushrooms, or even corn can be added for extra flavor and texture.
Variations
