Ingredients
Method
- Prep the produce and chicken. Thinly slice the peppers and onion. Slice the chicken into thin strips, about 1/2 inch wide, so it cooks quickly and evenly.
- Mix the spices. In a small bowl, combine chili powder, cumin, paprika, garlic powder, onion powder, oregano, crushed red pepper (if using), salt, and pepper.
- Season the chicken. Pat the chicken dry with paper towels. Toss it with half of the spice mix and 1 tablespoon of olive oil until evenly coated.
- Sear the chicken. Heat a large skillet (cast iron is great) over medium-high heat. Add the seasoned chicken in a single layer. Cook for 5–7 minutes, stirring once or twice, until the edges are slightly charred and the chicken is cooked through. Transfer to a plate.
- Cook the veggies. In the same skillet, add the remaining 1 tablespoon of olive oil. Add onions and peppers with a pinch of salt. Cook for 5–7 minutes, tossing occasionally, until tender-crisp with a bit of color.
- Combine and finish. Return the chicken to the skillet. Sprinkle the remaining spice mix over everything and toss to coat. Squeeze in the lime juice and cook 1–2 minutes more to meld the flavors. Adjust salt and pepper to taste.
- Warm the tortillas. Briefly heat tortillas in a dry skillet over medium heat for 20–30 seconds per side, or wrap in a damp towel and microwave for 20–30 seconds until soft.
- Serve. Fill warm tortillas with the chicken and peppers. Add your favorite toppings and a sprinkle of cilantro, if using. Serve immediately.

Storage Instructions

- Freezer: Freeze the chicken and pepper mixture in a freezer-safe bag for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheating: Rewarm in a hot skillet with a splash of water or broth to keep it moist, 3–4 minutes.
Microwave in short bursts, stirring between intervals.
- Meal prep tip: Portion into single-serve containers for quick lunches. Pack toppings fresh the day you eat.

What Not to Do
- Don’t overcrowd the pan. If the chicken steams instead of sears, you’ll miss that flavorful browning. Cook in batches if needed.
- Don’t slice the chicken too thick. Thick pieces take longer and can dry out on the outside before cooking through.
- Don’t skip the lime. That fresh acidity brightens everything and balances the spices.
- Don’t overcook the peppers. You want tender-crisp, not mushy.
A little char is perfect.
- Don’t add all the spice at once. Seasoning in two stages builds layers of flavor and avoids burning the spices early.
Recipe Variations
- Sheet Pan Fajitas: Toss chicken and veggies with oil and spices on a sheet pan. Roast at 425°F (220°C) for 18–22 minutes, flipping once.
- Chicken Thighs: Use boneless, skinless thighs for extra juiciness. Cook time may be 1–2 minutes longer.
- Citrus Marinade: Add 1 tablespoon lime juice and 1 tablespoon orange juice to the chicken with the spices.
Marinate 15 minutes if you have the time.
- Low-Carb Option: Serve in romaine or butter lettuce leaves, or over cauliflower rice.
- Veggie-Loaded: Add sliced mushrooms or zucchini in the last few minutes for extra volume.
- Spicy Kick: Add a minced jalapeño with the onions or finish with hot sauce and pickled jalapeños.
- Dairy-Free Creaminess: Top with guacamole or a cashew crema instead of sour cream.
- Smoky Restaurant Vibe: Use a cast-iron skillet and don’t stir too often—let the edges char a bit.
FAQ
Can I use pre-cooked chicken?
Yes. Slice it thin and add it during the final 2–3 minutes just to warm through with the peppers and spices. You may need a splash of water or broth to help the spices coat evenly.
What’s the best way to cut the chicken?
Slice against the grain into thin, even strips.
For easier slicing, chill the chicken in the freezer for 10–15 minutes beforehand to firm it up.
How do I prevent dry chicken?
Use high heat, don’t overcook, and slice thinly. A quick sear keeps juices in, and the final lime squeeze helps keep everything moist and bright.
Can I make this without a cast-iron skillet?
Absolutely. Any large, heavy skillet works.
Just preheat well and avoid overcrowding to get good browning.
What toppings go best with fajitas?
Classic options include sour cream or Greek yogurt, guacamole, pico de gallo, shredded cheese, cilantro, and lime wedges. For crunch, add thinly sliced radishes or shredded cabbage.
Are corn or flour tortillas better?
It’s personal preference. Flour tortillas are soft and flexible, great for larger fillings.
Corn tortillas bring a toasty flavor and are naturally gluten-free. Warm either one for the best texture.
How can I make it milder for kids?
Skip the crushed red pepper and reduce the chili powder. Offer mild toppings like cheese and avocado, and let everyone season their own at the table.
Can I meal prep this for the week?
Yes.
Cook the chicken and veggies, cool, and store in portions. Reheat quickly in a skillet and assemble with fresh toppings to keep textures lively.
What’s a good side dish?
Try cilantro-lime rice, black beans, charred corn, or a simple side salad. Chips and salsa never hurt either.
Is there a gluten-free option?
Use corn tortillas or lettuce wraps, and confirm your spices are certified gluten-free if needed.
