A quick and easy sheet pan fajita recipe featuring tender chicken, caramelized bell peppers, and onions roasted together with a vibrant spice blend. Perfect for busy weeknights and casual gatherings.

Ingredients

Scale
  • 1 lb (450 g) chicken breasts or thighs, thinly sliced
  • 3 medium bell peppers (mixed colors), sliced into strips
  • 1 large yellow or white onion, thinly sliced
  • 2 tablespoons olive oil
  • 1 teaspoon garlic powder
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1 teaspoon paprika (smoked paprika optional)
  • ½ teaspoon oregano
  • Salt and pepper to taste
  • 1 lime, juiced
  • Fresh cilantro (optional, for garnish)
  • Tortillas (flour or corn), warmed for serving

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken into thin strips about ½ inch thick. Slice the bell peppers and onion into similar-sized strips.
  3. In a large mixing bowl, combine olive oil, garlic powder, chili powder, cumin, paprika, oregano, salt, and pepper. Stir well.
  4. Add the sliced chicken, peppers, and onions to the bowl and toss to coat evenly with the seasoning mix.
  5. Spread the mixture evenly on a large rimmed sheet pan in a single layer, avoiding overcrowding. Roast in batches if necessary.
  6. Roast in the oven for 20–25 minutes, flipping the chicken and stirring the veggies halfway through (around 12 minutes) for even caramelization.
  7. Check that the chicken reaches an internal temperature of 165°F (74°C) and that the peppers and onions are tender with slightly charred edges.
  8. Remove from oven, squeeze fresh lime juice over the fajitas, and sprinkle with chopped cilantro if using.
  9. Warm the tortillas by wrapping them in foil and placing in the oven for the last 5 minutes or warming individually in a dry skillet over medium heat.
  10. Serve immediately, allowing everyone to build their own fajitas with preferred toppings like sour cream, guacamole, or shredded cheese.

Notes

For juicier chicken, marinate briefly (15-20 minutes) in lime juice and olive oil before seasoning. Avoid overcrowding the pan to ensure proper caramelization. Flip halfway through roasting for even cooking. Use corn tortillas or lettuce wraps for gluten-free options. Protein swaps like shrimp or tofu require adjusted roasting times.
