Chicken Fajitas

Juicy lime-marinated chicken, blistered bell peppers, and sweet onions come together in a hot skillet for a colorful fajita supper with warm tortillas.

A properly hot skillet is the heart of these fajitas. Cooking the chicken in a single layer gives the strips browned edges while keeping the center juicy, and the same pan picks up the sweetness of the peppers and onion.

Fresh lime, garlic, cumin, smoked paprika, and ancho chile make a quick marinade with enough depth for a weeknight dinner. Fifteen minutes is enough to season the thin chicken strips without softening their texture.

Red and yellow bell peppers bring color and a gentle sweetness, while poblano adds a mild green-chile flavor. The vegetables stay crisp-tender because they cook quickly over high heat instead of steaming.

Bring the skillet to the table while it is still sizzling and let everyone build their own fajitas. Warm tortillas, cool avocado, cilantro, and an extra squeeze of lime balance the savory chicken and charred vegetables.

Directions

  1. 1
    Lime-chile marinade in a bowl beside raw chicken strips

    Pat the chicken strips dry. In a large bowl, whisk the lime juice, 2 tablespoons olive oil, garlic, cumin, smoked paprika, ancho chile powder, oregano, 1 teaspoon salt, and black pepper.

  2. 2
    Marinated chicken strips beside sliced peppers and onion

    Add the chicken to the marinade and toss until every piece is coated. Let it stand at room temperature for 15 minutes while you slice the peppers and onion.

  3. 3
    Chicken strips beginning to sear in a cast-iron skillet

    Heat a large cast-iron skillet over high heat until a drop of water sizzles on contact. Add half of the chicken in a single layer and cook for 2 to 3 minutes without moving it.

  4. 4
    Browned chicken strips on a platter beside the skillet

    Turn the chicken and cook for 1 to 2 minutes more, until browned and the thickest pieces reach 165°F. Transfer to a platter and repeat with the remaining chicken.

  5. 5
    Fresh peppers and onion spread in a cast-iron skillet

    Add the remaining 1 tablespoon olive oil to the hot skillet. Add the bell peppers, poblano, onion, and remaining 1/4 teaspoon salt, spreading the vegetables into an even layer.

  6. 6
    Blistered peppers and onions in a cast-iron skillet

    Cook the vegetables over high heat for 5 to 7 minutes, tossing only every minute or two, until they have dark blistered spots but remain crisp-tender.

  7. 7
    Browned chicken tossed with blistered peppers and onions

    Return the chicken and any accumulated juices to the skillet. Toss for about 1 minute, scraping up the browned bits, until the chicken is hot and coated with the pan juices.

  8. 8
    Warm tortillas served with chicken fajitas, avocado, cilantro, and lime

    Warm the tortillas in a dry skillet or directly over a low gas flame until soft and lightly toasted. Serve the sizzling chicken and vegetables with the tortillas, avocado, cilantro, and lime wedges.

Tips & Notes

  • Cut the chicken across the grain into evenly sized strips so it cooks quickly and stays tender.
  • Do not crowd the skillet; two chicken batches create better browning and prevent the marinade from steaming.
  • For a milder dish, replace the poblano with a green bell pepper.
