How to Make Crockpot Chicken Fajitas with Peppers and Onions

Step 1: Prepare the Vegetables and Chicken

Start by slicing the bell peppers and onions into thin strips—it helps them cook evenly and absorb spices better. Trim any excess fat from the chicken breasts and pat them dry for better seasoning.

Step 2: Mix the Seasoning and Coat the Chicken

Combine your fajita seasoning spices with olive oil, minced garlic, salt, and pepper in a bowl. Rub this spice mixture all over the chicken breasts to ensure every bite is flavorful.

Step 3: Layer Ingredients in the Crockpot

Place the sliced onions and peppers at the bottom of the crockpot to create a flavorful bed, then lay the seasoned chicken on top. This layering helps the juices infuse upward so the veggies soak up all the wonderful flavors.

Step 4: Slow Cook to Perfection

Cover and cook on low heat for 6-7 hours or on high for about 3-4 hours. The slow cooking breaks down the chicken, making it tender and juicy while melding the spices and vegetables beautifully.

Step 5: Shred the Chicken and Mix

Once done, remove the chicken breasts, shred them using two forks, and stir them back into the peppers and onions. Squeeze in fresh lime juice for a zesty finish that brightens the entire dish.

Pro Tips for Making Crockpot Chicken Fajitas with Peppers and Onions

• Use fresh spices: Freshly ground chili powder and cumin make a noticeable difference in flavor quality.
• Avoid watery fajitas: Remove excess moisture from peppers before adding to crockpot to prevent sogginess.
• Low and slow: Cooking on low heat really brings out the tenderness in the chicken and melds flavors.
• Don’t skip the lime: The acid balances those rich spices and elevates the taste to another level.
• Double the batch: This recipe is great for meal prep and tastes even better the next day.
