Step‑by‑Step Instructions for Crockpot Chicken Fajitas

Step 1: Prep Ingredients
Start by slicing the boneless, skinless chicken breasts into strips for even cooking. Next, chop your bell peppers and onion into bite-sized pieces. This colorful medley adds both flavor and visual appeal to the Crockpot Chicken Fajitas. Set all your freshly chopped ingredients aside, ready for assembly.

Step 2: Combine Ingredients
In your slow cooker, place the sliced chicken followed by the chopped bell peppers and onions. Pour in the diced tomatoes, then sprinkle your homemade fajita seasoning over the top. This combination is key for that authentic fajita flavor, ensuring every piece of chicken and veggie is coated in savory goodness.

Step 3: Slow Cook
Cover the slow cooker and cook on low for about 4 hours, or if you’re short on time, set it to high for 2–3 hours. The chicken is done when it reaches an internal temperature of 165°F and juices run clear. During cooking, the aroma will fill your kitchen, inviting everyone to the table!

Step 4: For Instant Pot
If you’re opting for the Instant Pot, add the same sliced chicken, bell peppers, onions, and diced tomatoes to the pot, along with ½ cup of low-sodium chicken broth for moisture. Seal the lid and cook on high pressure for 10 minutes, followed by a natural release for 5 minutes. This method yields juicy and flavorful Crockpot Chicken Fajitas without the long wait.

Step 5: Serve
Once cooked, if you desire a shredded texture, use two forks to shred the chicken in the crockpot. Serve your delicious fajitas in fresh lettuce wraps for a low-carb option, or warm tortillas for a classic touch. Add your favorite toppings like avocado, cheese, or salsa, and enjoy this quick and healthy meal with family or friends!
