Follow these straightforward steps to bring your 30 Minute Sheet Pan Chicken Fajitas to life:

1. Preheat your oven: Set it to 400°F (200°C).
2. Prepare the baking sheet: Line a large baking sheet with parchment paper for easier cleanup.
3. Marinate the chicken: In a large bowl, combine sliced chicken with olive oil, fajita seasoning, garlic powder, salt, and black pepper. Toss until the chicken is well coated.
4. Add the vegetables: Add sliced bell peppers and onions to the same bowl. Mix well to combine everything.
5. Spread on the baking sheet: Transfer the chicken and vegetable mixture onto the prepared baking sheet in an even layer.
6. Bake: Place the baking sheet in the preheated oven. Roast for 15 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized.
7. Warm the tortillas: In the last few minutes of cooking, warm the tortillas in the oven or on a skillet over medium heat.
8. Check doneness: Ensure the chicken reads 165°F (75°C) with a meat thermometer.
9. Remove from oven: Carefully take out the baking sheet and allow it to cool for a couple of minutes.
10. Serve: Divide the fajitas into the warm tortillas and top with any optional toppings you desire.

By following these steps, you’ll create an incredible meal that’s not just satisfying but also easy to make.
