Chicken Fajitas, the Life Saving Dinner Hack of the Century

Fajita fanatics unite! We can all agree there’s just something about juicy chicken breast and tender veggies, seasoned to perfection and ready for copious amounts of toppings, that is so very craveworthy. Although our original chicken fajita recipe makes for a pretty quick weeknight dinner, we knew it was still even more time consuming that it needed to be. Traditionally, we would marinade the meat for an extended period of time and cook it, along with the veggies, separately in small batches to get that perfect char.

However!...and this is a big however… it just so happens that spreading chicken and veggies out over a sheet pan and tossing it with a little lime juice and taco seasoning and throwing it in the oven is not only way easier, it’s almost every bit as delicious!

How To Make Chicken Fajitas

We like to season these easy chicken fajitas with our (almost) world famous homemade taco seasoning. Because fajitas aren’t technically authentic Mexican cuisine—they fall more into the category of Tex-Mex—there is a lot of room for creativity when it comes to a good chicken fajita recipe. For the sake of ease, we highly recommend pre-making our taco seasoning in big batches and keeping it on-hand. However, if you’re really in a pinch, you can always buy it. Once you’ve got your taco seasoning, here are the next steps to making the fastest, best chicken fajitas, ever:

  • Make a marinade using the taco seasoning, olive oil and lime juice.
  • Toss chicken and vegetables in marinade.
  • Spread ingredients across the pan and bake for 15 minutes.
  • Serve with warm tortillas, salsa, guacamole, avocado, sour cream and fresh cilantro. Or turn your easy sheet pan dinner into a salad!

Our Favorite Fajita Marinade

This easy fajita marinade recipe requires just 3 ingredients. Lime juice, olive oil and taco seasoning. We make a simple marinade using our favorite homemade taco seasoning, olive oil and lime juice. You’ll find that this marinade is more of a paste than a liquid and we created it that way for good reason. The paste like consistency cuts down on the liquid that this easy sheet pan dinner will produce. Marinating the chicken ahead of time gives it great flavor, but if time isn’t your friend at the moment a quick toss will still yield delicious results!

What To Serve With Chicken Fajitas

Corn tortillas are one of the greatest things about Mexican cuisine, but there is a time and place for tender flour tortillas and chicken fajitas are it. Toast the tortillas in a pan with a little olive oil and fill them with the baked chicken fajita mixture. Then, serve those gorgeous fajitas with everything your heart desires! We like to serve them with:

Basically allllll the good stuff. Take liberties here, you really can’t go wrong going overboard with the toppings.

Using this fajita chicken and peppers mixture in a salad is also a GREAT way to use up leftovers! It’s healthy and tastes great (which is why we almost always make a double batch of these homemade chicken fajitas)!
