Step-by-Step Instructions

Step 1 — Prepare Your Ingredients

Slice 2 pounds of boneless, skinless chicken breasts into thin strips. Cut 1 large onion and 3 bell peppers (mixed colors) into thin strips. This uniform slicing ensures even cooking and perfect fajita texture.

Step 2 — Season the Chicken

In a small bowl, mix 2 tablespoons fajita seasoning, 1 teaspoon chili powder, 1 teaspoon cumin, and ½ teaspoon garlic powder. Rub this seasoning blend thoroughly over all chicken strips, coating every piece evenly for maximum flavor.

Step 3 — Layer Ingredients in Crockpot

Place seasoned chicken strips in the bottom of your 6-quart slow cooker. Top with sliced onions and bell peppers. Pour ¼ cup chicken broth over everything to create steam and prevent drying during the long cooking process.

Step 4 — Cook on Low Heat

Cover and cook on LOW for 6-7 hours. The chicken should reach an internal temperature of 165°F and shred easily with a fork when done. Avoid opening the lid frequently as this releases heat and extends cooking time.

Step 5 — Check for Doneness

After 6 hours, test chicken with a meat thermometer. If it hasn’t reached 165°F, continue cooking in 30-minute increments. The peppers should be tender but still hold their shape, not mushy.

Step 6 — Shred Chicken and Mix

Use two forks to shred the cooked chicken directly in the slow cooker. Gently mix with the peppers and onions to distribute flavors. The chicken should fall apart easily without being dry or stringy.

Step 7 — Serve Warm

Serve your Crockpot Chicken Fajitas immediately with warm tortillas, sour cream, guacamole, and lime wedges. For best texture, don’t let the mixture sit in the warm crockpot longer than 30 minutes after cooking.

Common Mistakes to Avoid

• Mistake: Overcooking the chicken, making it dry and stringy. Fix: Cook on LOW for 4-5 hours or HIGH for 2-3 hours, just until the chicken shreds easily.
• Mistake: Adding bell peppers and onions at the start. Fix: Stir them in during the last 30-60 minutes to keep them crisp-tender.
• Mistake: Skipping the sear on the chicken before adding it. Fix: Quickly sear chicken pieces in a hot pan first to lock in juices and add flavor.
• Mistake: Using too much liquid, creating a soupy filling. Fix: The vegetables and chicken release water; use only 1/4 to 1/2 cup of broth or salsa.
• Mistake: Not seasoning adequately, leading to bland fajitas. Fix: Generously coat the chicken with a homemade fajita seasoning blend.
• Mistake: Lifting the lid frequently to check progress. Fix: Keep the lid on to maintain consistent heat and cooking time.
• Mistake: Cutting chicken into uneven pieces. Fix: Slice chicken into uniform strips so they cook at the same rate.
• Mistake: Forgetting to taste and adjust seasoning before serving. Fix: Always do a final taste test and add salt, lime juice, or spices as needed.
• Mistake: Letting the finished fajitas sit in the warm crockpot too long. Fix: Serve immediately or switch to warm setting to prevent overcooking.

Storing Tips

• Fridge: Store cooled Crockpot Chicken Fajitas in an airtight container for up to 3-4 days.
• Freezer: Freeze in freezer-safe bags or containers for up to 3 months. Thaw in the refrigerator before reheating.
• Reheat: Reheat gently on the stovetop or in the microwave until the internal temperature reaches 165°F.

Always use a food thermometer to ensure your reheated Crockpot Chicken Fajitas reach a safe internal temperature of 165°F before serving.
