Best Chicken Fajita Recipe

Put away your Instant Pot or slow cooker. This recipe is the real deal…juicy chicken breasts cooked on a hot grill or skillet. There are no shortcuts, but the good news is, you don’t need shortcuts with this authentic recipe!

You’ll only need a handful of ingredients (six to be exact), and you can leave the chicken in the marinade overnight. Your chicken fajitas will be ready to go at a moment’s notice when you fire up the stove or pit!

To cook along with me, you can watch my YouTube video on how to cook chicken fajitas.

Recipe Notes

  • Use thinly sliced chicken breasts (preferably) or chicken tenders
  • Leave chicken in marinade overnight or at least 5-7 hours
  • Use either a grill or large skillet (cast-iron recommended) for best results
  • Make sure chicken reaches 165°F internal temp before serving. (I use this food thermometer to know for sure.)
  • Freeze your cooked chicken fajitas for an easy weeknight meal
  • Add pico de gallo, guacamole (avocado), cheese, sour cream, red peppers, yellow peppers, green bell peppers and onion, as desired
  • Squeeze fresh lime juice on cooked chicken fajitas for extra tangy flavor 
  • Serve with flour tortillas or corn tortillas

Serving Chicken Fajitas

In Texas, our preferred method of eating chicken fajitas is wrapped in a flour tortilla with guacamole and other garnishes like cilantro, colorful peppers, onion, cheese, pico de gallo and/or sour cream.

Of course, the final topping is usually a dab (or five) of spicy salsa. Squeeze a little lime wedge over your flame-licked chicken and mmmmm-mmmm!

We typically have charro beans (my favorite) or refried beans on the side as well as authentic Spanish rice. A margarita or Mexican beer doesn’t hurt if that strikes your fancy, too.

For dessert, try my pumpkin empanada recipe or Mexican flan recipe

    1. Oh, I hope you do try it! It’s one of our family favorites around here. I must make this at least twice a month if not more often. The best part is preparing it before bedtime and having it all ready to go the next day. You’ll thank yourself. Enjoy it!

    1. Oh, this is almost a weekly dish in our family. I do hope you’ll try it! It freezes well after you cook it, and you can always cook the chicken indoors in a cast-iron skillet or regular frying pan. Enjoy, my friend!

  1. I love this recipe Crissy! You show just how easy it is to make with your wonderful video. We love Mexican food, and this looks very authentic! I’ll be making it real soon! Thanks for sharing!

    1. Rebecca, you’re the sweetest! Thanks for watching my video. I love that you can make a big batch of these and feed your family throughout the week. We usually make quesadillas with the meat the next day to mix it up. I hope you and your family enjoy it!
