Ingredients

• For the fajitas:
  • 1 ½ pounds boneless, skinless chicken breasts, sliced against the grain into ½-inch strips
  • 3 bell peppers (green, yellow, and red), cored and sliced into strips
  • 1 yellow onion, thinly sliced
  • 2 cloves garlic, minced
  • 3 tablespoons vegetable or canola oil
  • 1 lime, juiced
  • ¼ cup fresh cilantro, chopped
  • 8–10 small flour tortillas
  • Toppings of choice: sour cream, avocado or guacamole, pico de gallo, shredded cheese
• Fajita seasoning:
  • 1 tablespoon chili powder
  • 1 ½ teaspoons paprika
  • 1 ½ teaspoons cumin
  • ½ teaspoon onion powder
  • ½ teaspoon garlic powder
  • ¼ teaspoon dried oregano
  • ¼ teaspoon cayenne pepper (optional)
  • Salt and freshly ground black pepper, to taste

Instructions

1. Prepare the sheet pan: Lightly grease a large sheet pan with non-stick spray. Arrange the sliced bell peppers and onion evenly across the pan. Place the chicken strips on top.
2. Season: In a small bowl, mix all fajita seasoning ingredients until well combined. Sprinkle most of the seasoning over the chicken and the rest over the vegetables. Add the minced garlic and drizzle everything with oil. Toss to coat and spread into an even layer.
3. Bake: Preheat oven to 425°F (220°C). Bake for 15–20 minutes, until the chicken is fully cooked (165°F when tested with a thermometer).
4. Warm tortillas: During the last 5 minutes of baking, wrap tortillas in foil and place them in the oven to warm.
5. Finish: Remove from the oven, squeeze lime juice over the fajitas, and sprinkle with fresh cilantro.
6. Serve: Fill warm tortillas with chicken and vegetables. Add your favorite toppings and serve immediately.

Tips

• Slice the chicken and vegetables evenly for quick, uniform cooking.
• Line the sheet pan with parchment paper for easier cleanup.
• Don’t overcrowd the pan—spread everything in a single layer so the chicken roasts instead of steams.
• For extra flavor, marinate the chicken in the seasoning and oil for 30 minutes before baking.

Variations and Substitutions

• Protein: Substitute chicken with shrimp, steak, or tofu.
• Tortillas: Use corn tortillas, lettuce wraps, or low-carb tortillas.
• Vegetables: Add mushrooms, zucchini, or cherry tomatoes for variety.
• Heat level: Adjust cayenne pepper to control spice, or add sliced jalapeños before roasting.
