Chicken Fajitas Crock Pot: Easy & Delicious Slow Cooker Recipe

August 12, 2025 by Lily author

Chicken Fajitas Crock Pot: Imagine coming home after a long day to the tantalizing aroma of sizzling fajitas, without having lifted a finger! This isn’t a dream; it’s the reality of this incredibly easy and delicious recipe. Forget standing over a hot stove – with just a few minutes of prep, your slow cooker does all the work, transforming simple ingredients into a fiesta of flavor.

While fajitas are a relatively modern Tex-Mex creation, their roots lie in the traditions of Mexican ranch workers in South and West Texas. They were often paid with less desirable cuts of beef, which they skillfully transformed into flavorful meals. Over time, the dish evolved, incorporating grilled meats and vibrant vegetables, becoming the beloved staple we know today. Now, we’re taking that classic and making it even easier!

People adore fajitas for their customizable nature, vibrant flavors, and the sheer joy of assembling your own perfect bite. The combination of tender, seasoned chicken, colorful bell peppers, and onions, all wrapped in a warm tortilla, is simply irresistible. This Chicken Fajitas Crock Pot recipe takes all the best parts of traditional fajitas and simplifies the process, making it perfect for busy weeknights. The slow cooking method ensures the chicken is incredibly tender and infused with flavor, creating a truly unforgettable meal. Get ready to enjoy restaurant-quality fajitas from the comfort of your own home, with minimal effort!

Chicken Fajitas Crock Pot this RECIPE

Ingredients:

  • 2 lbs boneless, skinless chicken breasts
  • 1 large onion, sliced
  • 2 bell peppers (any color), sliced
  • 1 (1 ounce) packet fajita seasoning
  • 1 (10 ounce) can diced tomatoes and green chilies (like Rotel), undrained
  • 1/2 cup chicken broth
  • 1 tablespoon olive oil
  • Optional toppings: sour cream, guacamole, salsa, shredded cheese, cilantro, lime wedges
  • Tortillas, for serving

Preparing the Chicken and Vegetables:

Okay, let’s get started! First things first, we need to prep our chicken and veggies. This is super easy, so don’t worry if you’re not a pro chef. I promise, this recipe is practically foolproof!

  1. Slice the Onions and Bell Peppers: Grab your large onion and those colorful bell peppers. Slice them into thin strips. I like to aim for about 1/4-inch thick slices. Don’t worry about being perfect; they’ll soften up beautifully in the slow cooker. The more colorful the peppers, the prettier the final dish will be! I usually go for one red and one yellow or orange pepper for a nice visual appeal.
  2. Prepare the Chicken: Now, take your chicken breasts and give them a quick rinse under cold water. Pat them dry with paper towels. This helps the seasoning stick better. You can leave the chicken breasts whole, or if they are very thick, you can slice them in half horizontally to help them cook more evenly and faster. I prefer to leave them whole because they shred easier after cooking.

Layering in the Crock-Pot:

Now comes the fun part – layering everything in the crock-pot! This is where the magic happens. The slow cooker will do all the hard work for us, infusing the chicken and veggies with all that delicious fajita flavor.

  1. Add Olive Oil and Onions: Drizzle the olive oil into the bottom of your slow cooker. This will prevent the chicken from sticking and add a little extra flavor. Then, spread the sliced onions evenly over the olive oil. The onions will act as a bed for the chicken and help to keep it moist.
  2. Layer the Chicken: Place the chicken breasts on top of the onions in a single layer. Try not to overlap them too much, so they cook evenly. If you halved the chicken breasts, arrange them so they are relatively flat.
  3. Add Bell Peppers: Now, scatter the sliced bell peppers over the chicken. Make sure they are evenly distributed, so every bite is packed with flavor.
  4. Sprinkle with Fajita Seasoning: Open that packet of fajita seasoning and sprinkle it evenly over the chicken and vegetables. Don’t be shy! This is where all the flavor comes from. I like to use a good quality fajita seasoning mix for the best results. You can also make your own if you prefer!
  5. Pour in Diced Tomatoes and Green Chilies: Pour the can of diced tomatoes and green chilies (Rotel) over the chicken and vegetables. Don’t drain the can! The liquid adds moisture and flavor to the dish.
  6. Add Chicken Broth: Finally, pour the chicken broth over everything. This will help to keep the chicken moist and create a delicious sauce.

Slow Cooking Process:

Alright, we’re almost there! Now it’s time to let the slow cooker do its thing. This is the best part because you can just set it and forget it. Go run errands, relax, or do whatever you need to do while your fajitas are cooking.

  1. Cook on Low or High: Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours. The cooking time will depend on your slow cooker and the thickness of your chicken breasts. You’ll know it’s done when the chicken is cooked through and easily shreds with a fork.
  2. Check for Doneness: After the recommended cooking time, check the chicken for doneness. Use a fork to see if it shreds easily. If it doesn’t, cook it for another 30 minutes to an hour, and then check again. The internal temperature of the chicken should be 165°F (74°C).

Shredding the Chicken:

Once the chicken is cooked through, it’s time to shred it. This is super easy to do right in the slow cooker. Just grab two forks and get to work!

  1. Shred the Chicken: Using two forks, shred the chicken directly in the slow cooker. It should be very tender and easy to shred. Mix the shredded chicken with the cooked vegetables and sauce.
  2. Mix Well: Stir everything together well to ensure the chicken is evenly coated with the sauce and vegetables.

Serving and Toppings:

Now for the best part – serving up those delicious fajitas! Warm up your tortillas and get ready to load them up with all your favorite toppings.

  1. Warm the Tortillas: Warm your tortillas according to the package directions. You can warm them in a skillet, in the microwave, or even over an open flame for a slightly charred flavor. I like to warm them in a dry skillet for a few seconds on each side until they are soft and pliable.
  2. Assemble the Fajitas: Spoon the chicken and vegetable mixture into the warm tortillas.
  3. Add Toppings: Top with your favorite toppings! Some of my favorites include sour cream, guacamole, salsa, shredded cheese, cilantro, and lime wedges. Get creative and add whatever you like!
  4. Serve Immediately: Serve the fajitas immediately and enjoy!

Tips and Variations:

Here are a few extra tips and variations to make this recipe even better!

  • Spice it Up: If you like your fajitas with a little extra kick, add a pinch of cayenne pepper or a few dashes of hot sauce to the slow cooker. You can also use a spicier fajita seasoning mix.
  • Add More Vegetables: Feel free to add other vegetables to the slow cooker, such as mushrooms, zucchini, or corn.
  • Use Different Protein: You can also use this recipe with other proteins, such as steak or shrimp. Just adjust the cooking time accordingly.
  • Make it Vegetarian: For a vegetarian version, use black beans or tofu instead of chicken.
  • Make it Ahead: You can prepare the fajita mixture ahead of time and store it in the refrigerator for up to 24 hours. Then, just add it to the slow cooker and cook as directed.
  • Freezing Instructions: Let the cooked fajita mixture cool completely. Transfer to a freezer-safe container or bag. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating. Reheat in a skillet or microwave until heated through.
  • Serving Suggestions: Serve with a side of rice and beans for a complete meal. You can also use the fajita mixture to make quesadillas, tacos, or salads.
Enjoy!
