Easy sheet pan chicken fajitas with charred peppers and onions. This 30-minute recipe is perfect for a weeknight dinner with minimal cleanup.

Ingredients

Scale
  • 1.5 lbs boneless, skinless chicken thighs or breasts, cut into 1/2-inch strips
  • 1 large red bell pepper, seeded and sliced
  • 1 large green bell pepper, seeded and sliced
  • 1 large yellow onion, sliced
  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 2 teaspoons cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon cayenne pepper (optional)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • Optional toppings: shredded lettuce, diced tomatoes, salsa, sour cream, shredded cheese, avocado, lime wedges
  • For serving: warm tortillas or cooked rice

Instructions

  1. Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup.
  2. In a large bowl, combine the chicken strips, sliced bell peppers, and sliced onion.
  3. In a small bowl, whisk together the olive oil, chili powder, cumin, smoked paprika, garlic powder, cayenne pepper (if using), salt, and black pepper.
  4. Pour the spice mixture over the chicken and vegetables. Toss well to ensure everything is evenly coated.
  5. Spread the chicken and vegetable mixture in a single layer on the prepared baking sheet. Make sure not to overcrowd the pan; use two pans if necessary to ensure proper browning and prevent steaming.
  6. Bake for 20-25 minutes, or until the chicken is cooked through and the vegetables are tender and slightly charred. For crispier vegetables, you can broil for the last 1-2 minutes, watching carefully to prevent burning.
  7. Serve the chicken fajita mixture immediately with warm tortillas or over cooked rice. Add your favorite toppings.

Notes

  • For chicken thighs, you may need to increase the cooking time slightly to ensure they are fully cooked.
  • To keep peppers crisp, ensure your oven is fully preheated and do not overcrowd the pan.
  • This recipe is great for meal prep. Portion the fajita mixture into containers with rice or tortillas for easy lunches.
  • Consider a meal planning service to simplify your weeknight dinners.
