Step‑by‑Step Instructions for Crockpot Chicken Fajitas
Step 1: Prep Ingredients
Begin by preparing your ingredients for the Crockpot Chicken Fajitas. Slice 2 pounds of chicken breasts into 1-inch strips, and thinly slice one red bell pepper, one yellow bell pepper, one green bell pepper, and one large yellow onion. Mince 6 garlic cloves for that aromatic touch. This step should take about 10-15 minutes, with your colorful chopping board ready to entice your culinary senses!
Step 2: Layer in Crockpot
Pour half of the 24 oz salsa into the bottom of your slow cooker, spreading it evenly. Next, layer half of your sliced bell peppers, onion, and minced garlic over the salsa. The vibrant colors should already start to appeal to your eyes, setting the stage for a delicious meal as you prepare for the chicken.
Step 3: Add Chicken
Carefully arrange the sliced chicken strips on top of the pepper and onion layers in the crockpot. Evenly sprinkle the fajita seasoning packet and 1 teaspoon of chili powder over the chicken to ensure all pieces are well-seasoned. This layering will allow the flavors to meld beautifully as the fajitas cook.
Step 4: Top with Salsa and Vegetables
Pour the remaining salsa over the chicken layer, ensuring it’s generously coated. Add the rest of the sliced peppers and onion on top, allowing their natural sweetness to add depth to the dish. For an extra zing, squeeze 2 tablespoons of lime juice over the entire mixture, as the acidity will help brighten the flavors.
Step 5: Cook
Cover your slow cooker with the lid and set it to cook on low for 6-8 hours or on high for 3-4 hours. Check the chicken’s internal temperature towards the end; it should reach 165°F for optimal safety and tenderness. As the chicken cooks, enjoy the delicious aromas wafting through your kitchen.
Step 6: Shred Chicken
Once cooked, use two forks to shred the chicken directly in the crockpot. This will allow the meat to soak up the flavorful juices and mix thoroughly with the peppers and onions. Stir well to combine, ensuring every bite of your Crockpot Chicken Fajitas is packed with savory goodness until you’re ready to serve.

Crockpot Chicken Fajitas Recipe FAQs
What type of chicken is best for Crockpot Chicken Fajitas?

Store your leftover Crockpot Chicken Fajitas in an airtight container in the fridge, where they will stay fresh for up to 4 days. The flavors actually deepen over time, making your next meal even more delicious!

If you find your fajitas are too watery, simply cook them uncovered on high for 15-20 minutes to allow excess liquid to evaporate. This helps thicken the sauce and enhances the dish’s overall flavor!
Can I personalize the recipe based on dietary restrictions?
Very! If you have dietary preferences or restrictions, feel free to substitute the chicken for a plant-based option like jackfruit or tofu. You can also skip the salsa for a fresh homemade sauce or replace any bell peppers with your favorite veggies if allergies are a concern. Enjoy experimenting!
