A quick and easy sheet pan chicken fajitas recipe that delivers juicy chicken and perfectly roasted peppers with bold, smoky flavors in just 30 minutes.

Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts, thinly sliced
  • 3 medium bell peppers (red, yellow, green), sliced into strips
  • 1 large yellow or white onion, sliced
  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon cayenne pepper (adjust to taste)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • Juice of 1 fresh lime
  • Optional toppings: sliced avocado, sour cream, shredded cheese, chopped cilantro, warm tortillas

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts into strips about 1/2 inch thick.
  3. Slice bell peppers and onion into strips roughly the same size as the chicken.
  4. Combine chili powder, cumin, smoked paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper in a small bowl to make the fajita seasoning.
  5. In a large bowl, toss the chicken strips with 1 tablespoon olive oil and half the fajita seasoning until well coated.
  6. In another bowl, toss the sliced peppers and onions with the remaining olive oil and fajita seasoning.
  7. Spread the chicken and veggies evenly across a rimmed sheet pan in a single layer.
  8. Roast in the preheated oven for 20 to 25 minutes, flipping the chicken and stirring the veggies halfway through cooking.
  9. Check that the chicken reaches an internal temperature of 165°F (74°C) and the veggies are tender with some charred edges.
  10. Remove from oven and immediately squeeze fresh lime juice over the pan. Toss lightly to combine.
  11. Serve hot with warm tortillas and your favorite toppings such as sliced avocado and sour cream.

Notes

Use a rimmed sheet pan to catch drippings and promote even roasting. Toss halfway through cooking for even texture and flavor. Keep chicken strips uniform in size to avoid drying out. For gluten-free, verify seasoning blend. For dairy-free, omit cheese or use plant-based alternatives. Fresh lime juice brightens the dish at the end.
