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

  • Amber

    Just looking for clarification, can you have flour tortillas if on whole 30 diet?

    No, that is why they are optional. You can find a replacement wrap or just eat it as a salad. Hope you enjoy.

  • 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

    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.

  • Jean

    OMG. My husband went wild for these. We did make one change-we put it on the grill. We just got Rolling Grilling Baskets and this dish was PERFECT for them. DELICIOUS!!!

    Thanks Jean, so glad you both enjoyed it!

  • Marge

    I made this dish and it was easy and delicious, can't wait to make them again.

    Thanks Marge, we are so happy you love it!

  • Kari

    This was so delicious and super easy! I was amazed at how juicy the chicken was! I really thought it would come out dry, but it didn't at all! I had 4lbs of chicken and used 3 packets of taco seasoning, added a little garlic, salt and cumin and about 2 to 3 tablespoons of lime juice (from a bottle) it turned out excellent!! Will definitely be making this again. I wish I could submit a picture of mine!

    Thanks Kari, we are so happy you loved it! If you have Instagram or facebook you can tag us in a picture, we'd love to see it!

  • Carole

    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!
