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)!

Questions & Reviews

  • Kathy

    Can a lemon be used instead of lime?

    We wouldn't recommend it in this recipe.

  • Alison

    For the 1 hour while the chicken and veggies marinate, do you suggest putting the pan in the refrigerator since it includes chicken?

    Yes! Hope you enjoy!

  • James

    Should the chicken breast be sliced and pounded out before cooking in oven or will the whole chicken breast cook in 15 mins at 375 degrees?

    You will cut the chicken into small slices before baking it. Hope you enjoy James!

  • Megan Fiocco

    It says it is 240 calories per serving. What is the serving size?

    we don't have yield currently for this recipe. So the serving size is just 1/6th of the recipe once it's completed.

  • Mag

    If I double this recipe should I double the baking time too?

    Doubling cook time would be too long. We'd recommend still checking it after 15 minutes and if it's not quite done cooking for another 5 minutes or so until there is no more pink in the chicken.

  • Carole L.

    Such a little effort for a huge flavor! Delicious meal with minimal time demands. I let the chicken mixture marinate in the fridge for a few hours. Absolute hit with us! Thank you!

    Thanks Carole, so happy you loved these!

  • Anna

    Very good! Am going to try with cauliflower rice and make a bowl out of it!

    Glad you enjoyed it Anna, making a bowl with cauliflower rice sounds delicious!

  • Elizabeth Mc

    These fajitas are now one of my favorite recipes! The ingredients can be prepared in advance and allowed to marinate, Easy to cook on a sheet pan. So delicious. I use cassava root tortillas for a gluten free meal.

    WOW, so happy to hear it's a favorite Elizabeth! Thank you.

  • Ariel

    This was really tasty and came together so quickly! I did end up pulling the chicken out at the end in order to broil the veggies without overdrying it, I think next time would cook separately or use chicken thighs vs breast. Parchment paper helped w cleanup at the end. Served with beans, spanish rice and tortillas with salsa, guac and sour was a lot of food. Definitely enough for at least 2 nights for 2 of us! Will make again!

    Thanks Ariel, so glad you loved it!

  • Chrissy Sorden

    This turned out so good! I love the recipe for the taco seasoning. Will definitely use it again! I only used half the onion and bell peppers (froze the other half), since the rest of my family will only eat the chicken. It is getting warmer so I decided to throw it in my air fryer. I did about 20 min on 380 and then 5 min on 400.

    Thanks Chrissy, we are so happy you loved it!
