Let's cook

  1. Heat the oven and the tray

    Preheat to 425°F (220°C) with the empty sheet pan inside. A hot tray sears the chicken on contact instead of letting it steam.

    💡

    Preheating the pan is the difference between charred fajitas and grey, watery ones.

  2. Season everything together

    Toss the chicken, peppers, and onion with the oil and all the spices until evenly coated. Use your hands — a spoon leaves clumps of spice.

  3. Spread in one layer

    Tip onto the hot pan and spread out so nothing overlaps. Use two pans if it looks crowded; crowding is what causes steaming.

  4. Roast

    Roast 18–20 minutes, tossing once at the halfway mark, until the chicken is cooked through and the pepper edges are blistered and blackening in spots.

  5. Finish and serve

    Squeeze the lime over the hot pan and toss. Warm the tortillas directly over a gas flame or in a dry skillet, then serve with sour cream, guacamole, and cilantro.

📝 Tips, swaps, and make-ahead notes

Chicken thigh stays juicier than breast at this temperature and is more forgiving if the pan runs a few minutes long. Cook to 165°F (74°C) internal. Any leftovers make excellent quesadilla filling.

  • Swap: Skirt steak works beautifully — roast 12 minutes only and slice against the grain.
  • Vegetarian: Portobello mushrooms and courgette in place of the chicken, roasted 15 minutes.
  • Make-ahead: Slice and season everything up to 24 hours ahead and keep it covered in the fridge.
