  • 2 pounds chicken breasts boneless skinless
  • 1 tbsp olive oil
  • 2 tsp chili powder
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp smoked paprika
  • 1 tsp cumin
  • 1/2 tsp black pepper
  • 2 tsp. kosher salt
  • 2/3 cup orange juice
  • 3 red bell peppers cut into 1/2 inch slices
  • 1 large red onion cut into 1/2 inch slices
  • 2 lime 1 juiced, and zest for marinade, 1 for serving
  • Freshly chopped cilantro

Options to Serve with:

  • Tortillas
  • Sour cream
  • Guacamole


  • In a small mixing bowl, whisk oil, chili powder, garlic powder, onion powder, smoked paprika, cumin, juice of one lime (plus zest), black pepper, and kosher salt.
  • Place the chicken breasts into a large resealable plastic bag and add the marinade mixture over the chicken. Seal the bag tightly and stir through the bag to evenly coat the chicken well with the marinade. Marinate the chicken in the refrigerator for at least 1 hour or overnight for a flavorful chicken.
  • Cut the onion and peppers into 1/2 inch thick slices. In a 6 quart crockpot, add the marinated chicken. Pour orange juice on top. Add chopped onion and bell peppers (see note). Cover the pot with the lid and cook on HIGH for 4 – 5 hours or until internal temperature reads 165 degrees F.
  • Once finished cooking, remove the chicken from the pot and slice into strips. Add a squeeze of half a lime juice and garnish with fresh cilantro leaves and lime wedges.
  • Serve fajitas in tortillas with your desired toppings.


  • Seasonings: These fajitas get all their flavor from the seasonings, so we don't suggest skipping any. If you need to use regular paprika instead of smoked you can. However, the smoked will add more flavor.
  • Bell peppers: You can substitute the red peppers for yellow or orange. For crunchier and more firm peppers, add them 30-45 minutes before the end of cook time.
  • Onion: You can substitute the red onion for a white or yellow onion.
  • Lime juice: For best results, use freshly squeezed lime juice and fresh lime zest.
  • Gluten-free option: You can use gluten-free tortillas, or alternatively you can serve chicken fajitas over a bowl of quinoa or brown rice for a gluten-free dinner.
  • Marinate longer for more flavor: To get the most flavor, marinate the chicken overnight or for several hours before cooking.
