Easy Chicken Fajitas
Sizzling strips of cumin-lime chicken with peppers and onions — fajita night done right.
Ingredients
Serves 4
- 1.5 lbs boneless, skinless chicken breasts, cut into 1/2-inch strips
- Juice of 2 limes
- 2 tbsp olive oil, divided
- 1 tsp ground cumin
- 1 tsp smoked paprika
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1 tsp chili powder
- 3 bell peppers (red, yellow, green), sliced thin
- 1 large onion, sliced thin
- 8 small flour or corn tortillas, warmed
- Sour cream, salsa, guacamole, and lime wedges to serve
Instructions
- 1In a bowl, combine lime juice, 1 tbsp olive oil, cumin, smoked paprika, garlic powder, onion powder, and chili powder. Add chicken strips and toss to coat. Marinate for at least 10 minutes at room temperature (or up to 4 hours in the fridge).
- 2Heat a large cast iron skillet or heavy pan over high heat until very hot. This high heat gives you that characteristic fajita sear and char.
- 3Add remaining 1 tbsp oil. Cook the chicken strips in a single layer, without stirring, for 2–3 minutes until charred on one side. Flip and cook another 2 minutes until cooked through. Transfer to a plate.
- 4In the same pan, add the sliced peppers and onions. Cook over high heat for 5–6 minutes, tossing occasionally, until softened and charred in spots. Season with a pinch of salt.
- 5Return the chicken to the pan and toss everything together for 1 minute to combine.
- 6Warm the tortillas directly over a gas flame for 30 seconds per side, or wrap in a damp towel and microwave for 30 seconds.
- 7Serve immediately in warm tortillas with your choice of sour cream, salsa, and guacamole. Squeeze extra lime over everything.
Pro Tips
- ✓
The key to great fajitas is screaming-hot heat. A medium-heat pan steams the chicken and vegetables instead of charring them. You want the pan to be hot enough that everything sizzles aggressively the moment it hits the surface.
- ✓
Don't skip the marinade rest — even 10 minutes in the cumin-lime mix significantly tenderizes the chicken and infuses flavor throughout.
- ✓
Slice peppers and onion lengthwise (pole to pole) rather than into rings — the longer strips stay intact during the high-heat sauté and look better in the tortilla.
Frequently Asked Questions
How do I keep chicken fajitas from being dry?
Marinate in lime juice (the acid tenderizes), cook on high heat quickly (overcooked chicken is dry chicken), and rest the strips for 2 minutes before serving so the juices redistribute. Thighs instead of breasts are also more forgiving — higher fat content keeps them juicy even with aggressive heat.
Can I make fajitas ahead for meal prep?
Yes — cook the chicken and vegetables fully, cool, and store in airtight containers for up to 4 days. Reheat in a hot skillet for 2–3 minutes so everything gets crispy again instead of steamed. Warm the tortillas just before serving.
What's the best tortilla for chicken fajitas?
Small flour tortillas (6-inch) are the classic choice — they're pliable and hold together well. Corn tortillas are naturally gluten-free and have better flavor, but they're more fragile. For the best of both, char both types directly over a gas flame for 30 seconds per side until blistered.
