• 1 large yellow onion, halved and sliced
• 4 cloves garlic, minced
• 2 1/2 tsp chili powder
• 2 tsp ground cumin
• 1 tsp paprika
• 3/4 tsp ground coriander
• 1 tsp salt
• 3/4 tsp black pepper
• 2 Tbsp fresh lime juice
• 1 Tbsp honey

For Serving

• Optional toppings: chopped cilantro, sour cream, salsa, guacamole or sliced avocados, shredded Mexican cheese

How to Make Crockpot Chicken Fajitas

1. Layer the ingredients. Pour half of the canned tomatoes into the bottom of the slow cooker and spread evenly. Add half of the sliced peppers, half of the onions, and the minced garlic. Place the chicken breasts on top.
2. Season the chicken. In a small bowl, whisk together chili powder, cumin, paprika, coriander, salt, and pepper. Sprinkle half of the seasoning over the chicken, flip, and sprinkle with the remaining seasoning.
3. Finish layering. Top with the remaining tomatoes, then add the rest of the peppers and onions.
4. Slow cook. Cover and cook on HIGH for 2–3 hours or on LOW for 4–6 hours, until the chicken is fully cooked and vegetables are tender.
5. Shred and finish. Remove the chicken and shred or slice it. Ladle out about 1 cup of broth from the slow cooker and discard.
6. Combine and serve. Whisk lime juice and honey together, add to the slow cooker with the chicken, and gently toss. Adjust seasoning if needed and serve warm in tortillas with your favorite toppings.
