Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts or thighs, sliced into thin strips
  • 3 medium bell peppers (red, yellow, green), sliced into strips
  • 1 large yellow or white onion, thinly sliced
  • 3 tablespoons extra virgin olive oil
  • 1 teaspoon chili powder
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon crushed red pepper flakes (optional)
  • 1 teaspoon salt (adjust to taste)
  • 1/2 teaspoon black pepper
  • Juice of 1 lime
  • A handful of fresh cilantro, chopped (optional)
  • Warm flour or corn tortillas, for serving
  • Optional toppings: sour cream, shredded cheese, avocado slices, pico de gallo

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts or thighs into thin strips about 1/2 inch thick. Slice bell peppers and onions into similar strips.
  3. In a small bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, crushed red pepper flakes (if using), salt, and black pepper to make the fajita seasoning.
  4. In a large mixing bowl, toss the sliced chicken, bell peppers, and onions with olive oil and the fajita seasoning until evenly coated.
  5. Spread the mixture in a single layer on a large rimmed baking sheet.
  6. Roast in the oven for 20-25 minutes, stirring and flipping the chicken and veggies halfway through cooking (around 12 minutes) for even browning.
  7. Check that the chicken reaches an internal temperature of 165°F (74°C) and that the veggies are tender with caramelized edges.
  8. Squeeze the juice of one lime over the hot fajitas and sprinkle with chopped cilantro.
  9. Serve immediately with warm tortillas and optional toppings like sour cream, shredded cheese, avocado, or pico de gallo.

Notes

Slice chicken and vegetables uniformly for even cooking. Toss halfway through roasting to ensure browning. Use fresh spices for best flavor. Let chicken rest briefly after roasting to keep it juicy. Adjust heat by adding or omitting crushed red pepper flakes. Avoid overcrowding the pan to prevent steaming.
