Step-by-Step: Sheet Pan Chicken Fajitas

Step 1: Preheat Your Oven
Begin by preheating your oven to 400°F (200°C). This ensures that your fajitas roast evenly and develop a lovely caramelization.

In a mixing bowl, combine the cut chicken thighs, sliced onions, and bell peppers. Drizzle with avocado oil and sprinkle with chili powder and sea salt. Toss everything together until well coated.
Step 3: Spread on the Sheet Pan
Transfer the mixture onto a large sheet pan, spreading everything out in a single layer. This helps to achieve that perfect roast.
Step 4: Roast Until Tender
Place the sheet pan in the preheated oven and roast for about 25-30 minutes, or until the chicken is cooked through and the vegetables are tender. You may want to stir halfway through for even cooking.
Step 5: Serve and Enjoy
Once done, remove the pan from the oven and let it cool slightly. Serve your Sheet Pan Chicken Fajitas in warm tortillas, or over rice, topped with your favorite garnishes like avocado, salsa, or fresh cilantro.
