Equipment

• Large dark rimmed sheet pan (18x13 inch)
• Parchment paper
• Large mixing bowl
• Tongs
• Cutting board and chef's knife
• Measuring spoons

Instructions

1. Preheat your oven to 425°F (218°C) and line a large dark rimmed sheet pan with parchment paper.
2. In a small bowl, whisk together chili powder, ground cumin, garlic powder, onion powder, smoked paprika, dried oregano, salt, and black pepper.
3. Place the sliced chicken breast strips, bell pepper strips, and yellow onion wedges into a large mixing bowl.
4. Drizzle olive oil evenly over the chicken and vegetables in the mixing bowl.
5. Sprinkle the prepared fajita seasoning mixture over the bowl and toss thoroughly with tongs until every piece is uniformly coated.
6. Spread the seasoned chicken, peppers, and onions onto the parchment-lined large dark sheet pan in an even, single layer.
7. Ensure space between the pieces so the chicken and vegetables roast rather than steam.
8. Place the sheet pan into the preheated 425°F oven on the middle rack.
9. Bake for 15 minutes undisturbed until the chicken is cooked through and vegetables are tender-crisp.
10. Switch the oven to high broil for 2 to 3 minutes, watching closely, until the edges of the peppers and chicken are charred and blistered.
11. Remove the sheet pan carefully from the oven using oven mitts.
12. Verify that the chicken reaches an internal temperature of 165°F with an instant-read thermometer.
13. Squeeze fresh lime juice from two lime wedges evenly across the hot chicken and peppers.
14. Wrap the tortillas in foil and warm them in the oven for 3 minutes while the fajitas rest.
15. Sprinkle chopped fresh cilantro across the roasted chicken and peppers on the sheet pan.
16. Serve immediately with warm tortillas and your favorite fajita toppings.

Chef's Tips

1. Prevent Soggy Fajitas: High heat is crucial! Roasting at 425°F and spreading ingredients in a single layer ensures moisture evaporates quickly, allowing peppers to brown and blister rather than steam in their own juices.
2. Customizing the Protein: Swap chicken breasts for boneless skinless chicken thighs for even juicier meat, or use thin strips of flank steak or sirloin (reduce roast time by 3-4 minutes for beef).
3. Meal Prep & Storage: Keep leftover fajita chicken and peppers in an airtight container for up to 4 days. Reheat in a hot skillet for 3 minutes to restore the crispy edges, then serve over rice or in warm wraps.
