Step‑by‑Step Instructions for Crockpot Chicken Fajitas
Step 1: Season the Chicken
Begin by rubbing your 2 ½ pounds of boneless, skinless chicken breasts or thighs with the spice blend, ensuring both sides are well-coated. The spices include garlic powder, chili powder, cumin, onion powder, smoked paprika, oregano, salt, and black pepper. This step should take about 5 minutes, allowing the flavors to permeate the chicken before cooking.
Step 2: Add Tomatoes and Chiles
Place the seasoned chicken in the crockpot and pour the can of fire-roasted diced tomatoes with green chiles over the top. Use a spoon to gently stir the mixture, ensuring the chicken is submerged in the flavorful tomato juices. This creates a rich base for your Crockpot Chicken Fajitas as it cooks, locking in moisture throughout the process.
Step 3: Cook
Cover the crockpot with its lid and cook on the low setting for approximately 5 hours or on high for about 3 hours. You’ll know it’s ready when the chicken is fork-tender and shreds easily. The aroma of Tex-Mex spices will fill your kitchen, drawing everyone to the table in anticipation of this delicious meal.
Step 4: Add Peppers and Onions
About 45 minutes before the cooking time is complete, slice the bell peppers and onion, and add them to the crockpot. Stir gently to combine, allowing the vegetables to cook without losing their vibrant color and crunch. This adds a delightful texture and fresh flavor to your Crockpot Chicken Fajitas.
Step 5: Shred the Chicken
Once the cooking time has finished, carefully remove the chicken from the crockpot and place it on a cutting board. Use two forks to shred the chicken into bite-sized pieces, then return it to the pot. Squeeze fresh lime juice over the mixture, stirring it in to enhance the flavors and provide that signature zesty brightness.
Step 6: Serve
Warm up flour tortillas and scoop generous portions of the chicken and vegetable mixture onto each tortilla. Top with your favorite toppings, such as shredded cheese, guacamole, salsa, and sour cream. Serve the Crockpot Chicken Fajitas immediately, and enjoy a hearty, flavorful meal that brings a taste of Tex-Mex to your table!

Make Ahead Options
These Crockpot Chicken Fajitas are a meal prep dream! You can season the chicken and combine it with the diced tomatoes up to 24 hours in advance. Simply refrigerate the mixture in an airtight container to ensure it stays fresh and flavorful. You can also slice the bell peppers and onions ahead of time, storing them separately for up to 3 days in the fridge to maintain their crunch. When it’s time to cook, add the chicken mixture to the crockpot, toss in the veggies 45 minutes before serving, and let the slow cooker work its magic. This way, you’ll have a delicious, home-cooked meal ready to enjoy with minimal effort!
