How to Make Sheet Pan Chicken Fajitas
- Start by preheating your oven to 375°F (190°C). This ensures even cooking and helps everything bake to perfection.
- In a large mixing bowl, combine the diced chicken, olive oil, and all the spices. Mix until the chicken is well-coated.

- Then, toss in the minced garlic, sliced bell peppers, and red onion. Stir everything together to ensure the veggies are coated in that flavorful seasoning.

- Line a sheet pan with parchment paper or lightly grease it. Spread the chicken and veggie mixture evenly across the pan in a single layer.

- Bake for 30-35 minutes or until the chicken is fully cooked and golden brown. For an extra flavor, broil for the last 2-3 minutes.

- Warm your tortillas according to the package instructions or your preference. Add a generous portion of the chicken and veggie mixture to each tortilla.
- Top your fajitas with fresh lime juice, diced avocado, sour cream, shredded mozzarella, and a sprinkle of chopped cilantro.
