Cuisine Mexican
- 1½ pounds boneless skinless chicken breasts, sliced into strips
- 3 bell peppers sliced (any color)
- 1 large onion sliced
- 2 tablespoons olive oil
Fajita Seasoning
- 1 teaspoon chili powder
- 1 teaspoon smoked paprika
- 1 teaspoon cumin
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
For Serving
- Tortilla Shells
- Lime wedges
- Fresh cilantro optional
Preheat your oven to 400°F (200°C).
Slice the chicken breasts into thin strips. Slice the bell peppers and onion into similar-sized strips so everything cooks evenly.
Place the chicken, peppers, and onions in a large mixing bowl. Drizzle with olive oil and sprinkle with the fajita seasoning.
Toss everything together until evenly coated.
Spread the mixture in an even layer on your sheet pan.
Try not to overcrowd the pan — this allows the ingredients to roast instead of steam.
Bake for 18–22 minutes, or until the chicken is fully cooked and the vegetables are tender.
You can broil for the final 2 minutes if you want extra caramelization.
Remove from the oven and serve immediately in warm tortillas with lime wedges and your favorite toppings.
