Whip up a family-friendly take on the Mexican favorite with this quick, easy recipe for Sheet Pan Chicken Fajitas!

There’s nothing I love more than an easy, breezy one-pan meal, and that’s where my sheet pans really pull their weight. My latest fast, family-friendly dinner recipe to enter our weekly rotation comes in the form of Sheet Pan Chicken Fajitas, complete with a rainbow of veggies.

How to Make Chicken Fajita Seasoning

Don’t get me wrong, I love the ease (and salty heat) of taco seasoning from a store-bought packet. But I knew I wanted to dial up the flavors for these family-friendly chicken fajitas to suit everyone’s taste … without all that extra sodium.

The key to any great fajita seasoning is ground cumin, while oregano and chili pepper add even more dimension and color to this mix. Once you’ve combined your spices, sprinkle them liberally over your chicken and vegetables. You just might find yourself never looking at pre-made spice mixes again!

How to Make Chicken Fajitas In the Oven

The set up for this recipe really couldn’t be simpler. After you slice up chicken breasts, a rainbow of bell peppers and red onions, you toss them all together with homemade taco seasoning. Once you transfer the mixture onto a sheet tray, you can let the oven do the rest of the work, leaving plenty of time to kick back (and maybe even mix up an Orange and Mango Margarita).

The Best Chicken Fajita Toppings

Top these fajitas with your favorite store-bought or homemade guacamole, salsa, sour cream and shredded cheese. I love finishing them off with Cotija cheese crumbles and quick-pickled red onions for a bit of spice and bite.

If you’re looking to complete your Mexican feast, don’t forget Peach Sangria Popsicles for a beverage that doubles as a dessert. Want an even sweeter finale? Try my Easy Homemade Churros with Chocolate Sauce, too!

    These were AWESOME. I love that my stove didn’t get all greasy and splattered and the flavor was spectacular. Served them with warm corn tortillas, guacamole and my homemade salsa. Huge hit!

      1. Absolutely! Just toss the warm shredded chicken with the taco seasoning and roast the veggies on the sheet pan.
