In a small bowl, combine olive oil, chili powder, and half of the lime juice. This marinade is crucial for infusing flavor into the chicken. Season with a pinch of salt, then pour it over the chicken breasts. Make sure they're well-coated and then cover the bowl. Allow it to refrigerate for 30 minutes, letting the flavors meld.
Meanwhile, preheat your grill to high heat. If you’re using a charcoal grill, get those coals nice and hot. You want a good sear on the chicken. Once ready, place the marinated chicken on the grill, cooking until it's completely cooked through. This should take about 10 minutes per side, depending on the thickness of the breasts. Look for a nice char on the outside.
Once grilled, transfer the chicken to a cutting board and let it rest for about 5 minutes. This step is essential as it allows the juices to redistribute, making the chicken tender and juicy. After resting, slice the chicken thinly, ensuring each bite is packed with flavor.
If you prefer a stovetop method, you can pan-sear the chicken instead. After marinating, heat a large skillet over medium-high heat. Add a tablespoon of oil, then sear the chicken on both sides until browned and cooked through. Rest and slice as mentioned before.
While the chicken is resting, prepare your cilantro crema. In a small bowl, combine sour cream, cilantro, ground cumin, and the remaining lime juice. Stir until smooth and creamy. This will be drizzled over the tacos for added richness.
Now it’s time to warm up the tortillas. Heat a nonstick skillet over medium heat and place each tortilla in, warming it for about 10 seconds on each side. This step helps them stay pliable and enhances their flavor.
Now assemble your tacos! Start with a warm tortilla, add a generous portion of sliced chicken, then top with avocado, tomato, and a drizzle of the cilantro crema. If you like it spicy, don’t forget your favorite salsa!
