How to Make Sheet Pan Chicken Fajitas
1. Preheat & Prep: Preheat your oven to 425°F. Lightly grease a large sheet pan with non-stick spray.
2. Chop & Arrange: Slice the chicken and vegetables into thin strips. Arrange the bell peppers and onions evenly across the sheet pan, then place the chicken on top.
3. Season Everything: In a small bowl, mix all the fajita seasoning ingredients. Sprinkle most of it over the chicken, and the rest over the veggies. Add minced garlic and drizzle with oil. Toss everything well to coat and spread evenly.
4. Roast to Perfection: Bake for 15-20 minutes, or until the chicken is cooked through and the vegetables are tender.
5. Final Touches: Remove from the oven, squeeze fresh lime juice over everything, and stir in chopped cilantro for a fresh burst of flavor.
6. Serve & Enjoy: Load up warm flour tortillas with your delicious fajitas and pile on your favorite toppings. Dig in!
