<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4> Begin by preparing your chicken strips. In a large mixing bowl, combine the chipotle chili powder, smoked paprika, ground cumin, garlic powder, oregano, salt, and black pepper. This creates your authentic Chipotle-style seasoning blend. Add the sliced chicken strips to this spice mixture and toss thoroughly, ensuring every piece is evenly coated. Let the chicken marinate for at least 15 minutes at room temperature, or up to 2 hours in the refrigerator for deeper flavor penetration.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4> While the chicken marinates, prepare your vegetables. Slice the bell peppers into strips about 1cm wide, removing all seeds and white pith. Cut the white onion into similar-sized strips, maintaining consistency for even cooking. Having uniform cuts ensures everything cooks at the same rate, just like in Chipotle's kitchens.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4> Heat a large cast-iron skillet or heavy-bottomed pan over medium-high heat. Add 2 tablespoons of vegetable oil and let it heat until it shimmers but doesn't smoke. This high heat is crucial for achieving those beautiful caramelized edges that make Chipotle fajitas so irresistible.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4> Add the marinated chicken strips to the hot pan in a single layer, being careful not to overcrowd. You may need to cook in batches. Let the chicken sear undisturbed for 3-4 minutes until golden brown on one side, then flip and cook for another 2-3 minutes. The internal temperature should reach 75°C when checked with a meat thermometer. Remove the cooked chicken to a plate and tent with foil to keep warm.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4> In the same pan, add the remaining tablespoon of oil if needed. Add the sliced onions first and cook for 2-3 minutes until they begin to soften and develop those lovely golden edges. The residual chicken flavors in the pan will add incredible depth to your vegetables.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4> Add the bell pepper strips to the pan with the onions. Cook for 4-5 minutes, stirring occasionally, until the peppers are tender-crisp and slightly charred in spots. You want them to retain some bite, not become mushy. The natural sugars in the vegetables should caramelize beautifully, creating that signature Chipotle flavor.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4> Return the cooked chicken to the pan with the vegetables and toss everything together. Drizzle with fresh lime juice and give it a final toss for 1 minute to allow all the flavors to meld together. The lime juice will brighten all the smoky, earthy spices and add that authentic Chipotle tang.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4> While the fajita mixture finishes cooking, warm your tortillas. You can do this by wrapping them in damp paper towels and microwaving for 30 seconds, or by heating them individually in a dry pan for 15-20 seconds per side until they're warm and pliable.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4> Prepare your serving station with warm cilantro-lime rice in bowls, heated black beans, shredded cheese, sour cream, and fresh salsa. Having everything ready means your fajitas will stay hot while assembling.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4> Serve the sizzling fajita mixture immediately on warmed tortillas. Let each person build their own fajitas by adding rice, beans, the chicken and vegetable mixture, cheese, sour cream, and salsa according to their preferences. Garnish with fresh cilantro leaves and serve with lime wedges for that final burst of citrusy freshness that makes these fajitas truly authentic.</li></ol>
