Ingredients

Protein and Vegetables

  • 1 pound boneless skinless chicken breasts
  • 2 bell peppers (green, red, yellow, or orange), sliced
  • 1 medium red onion, sliced

Seasoning and Extras

  • ¼ cup olive oil
  • 2 teaspoons dried oregano
  • 1 teaspoon dried cumin
  • 1 teaspoon dried garlic powder
  • ½ teaspoon dried paprika
  • ¼ teaspoon dried cayenne pepper
  • 1 teaspoon salt
  • Juice of 1 medium lime (about 2 tablespoons)
  • 8 small tortillas (flour or corn), for serving

Instructions

  1. Preheat the Oven: Set your oven to 425°F (220°C) and lightly oil the baking sheet to prevent sticking and enhance roasting.
  2. Slice Ingredients: Cut the chicken breasts into thin ¼-inch strips against the grain to ensure tenderness. Slice the bell peppers and red onion into similar ¼-inch strips for even cooking. Arrange the chicken and vegetables in a single, even layer on the prepared sheet pan.
  3. Prepare the Spice Mixture: In a small bowl, combine the olive oil, dried oregano, cumin, garlic powder, paprika, cayenne pepper, and salt. Pour this seasoning mixture evenly over the chicken and vegetables on the pan. Gently toss to coat all pieces thoroughly with the oil and spices.
  4. Roast the Fajitas: Place the sheet pan in the preheated oven and roast for 25-30 minutes. Check for doneness by ensuring the chicken reaches an internal temperature of 165°F (74°C). The vegetables should be tender and slightly caramelized.
  5. Serve: Warm the tortillas, then serve the roasted chicken and vegetables wrapped in the tortillas. Squeeze fresh lime juice over the fajitas to enhance the flavors and enjoy!

Notes

  • Slicing chicken against the grain helps to keep it tender and juicy.
  • You can use any combination of bell peppers based on your preference or what you have available.
  • Adjust cayenne pepper to your desired level of spice or omit for a milder flavor.
  • Ensure the chicken is cooked through by checking the internal temperature with a meat thermometer.
  • For gluten-free options, use corn tortillas instead of flour tortillas.
