How to Make Sheet-Pan Chicken Fajitas

This easy sheet-pan recipe has all the flavor of traditional fajitas, but without the hassle. There’s no need to start up the grill or stand over a hot stove—just toss everything on a sheet pan, bake, and enjoy a flavorful, fuss-free meal.

Prep your ingredients

Heat the oven to 400°F and slice the chicken, bell peppers, and onions into thin strips. Set the veggies aside.

Cook the chicken and vegetables

Season the chicken with salt and bake for 15 minutes until it starts to brown. Add the veggies to the pan, drizzle with oil, and season with Old El Paso™ Fajitas Seasoning. Return to the oven until the veggies are tender and the chicken is fully cooked.

Add your toppings

Serve your sheet-pan chicken fajitas with your favorite Tex-Mex toppings, along with cilantro and lime wedges for extra fresh and zesty flavor. Check out the full recipe details below!

Storing and Reheating Sheet-Pan Chicken Fajitas

You can store leftover chicken fajitas in an airtight container in the fridge for up to 3 days—just make sure to keep the tortillas separate to prevent sogginess.

For the best flavor and texture, reheat the chicken and veggies in a skillet over medium heat for a few minutes until warmed through. If you're short on time, reheat in the microwave in 30-second bursts, stirring in between.
