Classic Grilled Chicken Fajitas

I love fajitas and have made them on a sheet pan, made them in my cast iron skillet and I have a dry Fajita Seasoning on my site. Every once in a while I want the real deal. Real deal smoky, garlicky, lime-y grilled fajitas. Classic Grilled Chicken Fajitas.

Yep, Classic Grilled Chicken Fajitas that are going to remind you, when you make them, of all that’s good about Fajitas. It will take you back (if you’re old enough to remember) to when fajitas started appearing in restaurants, brought to the table sizzling and hot on a cast iron pan. That was the dish you’d order that would turn everyone’s heads as the waitress (or waiter) wove through the tables to yours.

About Classic Grilled Chicken Fajitas:

And so the sheet pan version is good, and the precut veggies, sometimes frozen, are alright, but every once in a while, you should treat yourself. To smokey, sizzling, juicy strips of chicken that wake up your taste buds, beautifully cooked veggies, and all the great accompaniments you could ever want.

Remember to heat up lots of extra tortillas. You’ll always need more than you think because you’ll start stuffing them and realize fast that you’re running out room as you take a bite and everything slips out the backside of your tortilla!

I like to serve my fajitas with black beans (I just usually doctor up a can with a little garlic & cumin) and a side of Mexican Rice. Either this Classic Mexican Rice or this Instant Pot Version. And of course, some of my fave accompaniments.

Making Classic Grilled Chicken Fajitas:

I’m pretty sure this recipe is from Cook’s Illustrated. Or maybe Cook’s Country or America’s Test Kitchen. I didn’t note it in my recipe box, but the great detail in the recipe makes me think that’s a big possibility. And also I seem to remember they are the ones that came up with the great idea of saving out some of that marinade and tossing it in with the cooked chicken and veggies, infusing them with fresh flavor right before they’re served.

Just start off on the grill with the onions first, then the peppers and then the chicken because the onions take the longest to cook, then the peppers, then the chicken. And if you want to do each of the tortillas indiviuaually that’s fine; they’ll pick up a nice smoky grilled flavor. If you’re not feeling that, you can put them in packets of six, wrapped in foil and heat them on a low part of the grill turning now and then.

Saving Money on Classic Grilled Chicken Fajitas:

Fajitas are actually pretty inexpensive to make, and so are the sides. It’s seriously all the accompaniments that start adding up! Watch for your chicken on sale; it usually comes in larger family packs so break it down to convenient sizes and freeze. Bell peppers go on sale regularly and last a week or two in the fridge. Buy them when you see them, and buy a few extra for the following week.

Cheese is regularly on sale, and so is sour cream, so get in the habit of picking items like this up before you need them, when you see them on sale, if you use them regularly. As far as the tortillas, I rarely see them on sale. Look for them in endcaps, in the refrigerator section, and in the Mexican food aisle and compare the prices.

  • Author: mollie adapted probably from Cooks Illustrated




zest of 1 lime
1/3 cup juice from 2 to 3 limes
4 tablespoons vegetable oil, divided
3 medium garlic cloves, minced or pressed
1 tablespoon soy sauce
1 1/2 teaspoons brown sugar
1/2 teaspoon salt (or to taste)
1/2 teaspoon pepper
1/4 teaspoon cayenne
1/4 teaspoon liquid smoke (mesquite preferred)
1 jalapeno, seeds and ribs removed, minced or use half as much and press through a garlic press


3 boneless, skinless chicken breasts (about pounds), trimmed of fat, tenderloins removed, pounded to ½-inch thickness (see note)
1 large red onion or 2 white, peeled and cut into ½-inch-thick rounds (do not separate rings)
1 large red bell pepper, quartered, stemmed, and seeded
1 large green or yellow bell pepper, quartered, stemmed, and seeded
1/4 teaspoon salt
1/4 teaspoon pepper
8 to 12 (6-inch or fajita size) flour tortillas
Garnishes: Choice of minced fresh cilantro, lime wedges, guacamole, salsa, sour cream, pickled jalapenos, olives, cheese of choice: Cheddar, Monterrey Jack, queso fresco or feta


In a medium bowl, whisk together the marinade ingredients, the lime zest & juice, 2 tablespoons oil, garlic, soy sauce, brown sugar, 1/2 teaspoon salt, and 1/2 teaspoon pepper, cayenne, and jalapeno. Reserve 1/2 marinade in a small bowl; set aside. Place the chicken and the remaining marinade in Ziploc set aside for 1/2 hour; may marinade longer, but refrigerate. Brush both sides of the onion rounds and the peppers with the remaining 2 tablespoons oil and season with 1/4 teaspoon each of salt and pepper.

Prepare grill and bring a large piece of foil to tent the fajitas with and a clean kitchen towel to wrap tortillas in when they come off the grill.

  • Build a two-level fire using coals. Using a large chimney starter, ignite 6 quarts of charcoal briquettes and burn until the coals are fully ignited, about 20 minutes. Empty the coals into the grill, spreading them in a single layer; place an additional 20 unlit coals over the lit coals on one side of grill to create a two-level fire. Position the grill grate over the coals and heat the grate for 5 minutes; scrape clean with a grill brush.
  • Build a two-level fire with gas: For a gas grill, light all burners and turn to high, cover, and heat the grill until hot, about 15 minutes; scrape the grill grate clean with a grill brush. Leave one burner on high heat while turning the remaining burner(s) down to medium.

To grill the vegetables:

Place the onion rounds and peppers (skin side down) on the cooler side of the grill. cook the onions until tender and charred on both sides, 10 to 12 minutes, turning every 3 to 4 minutes. Meanwhile, cook the peppers until spottily charred and crisp-tender, 8 to 10 minutes, turning once or twice as needed;

To grill the chicken:

Remove the chicken from the marinade and place it smooth side down on the hotter side of the grill; discard the remaining marinade. Cook the chicken until it’s well browned, 4 to 5 minutes; using tongs, flip the chicken and continue grilling until it’s no longer pink when cut into with a paring knife or an instant-read thermometer inserted into the thickest part registers about 160 degrees, 2 to 3 minutes longer.

As the chicken and vegetables are done, transfer them to a large plate; tent with foil to keep warm.

To grill tortillas:

Working in 2 or 3 batches, place the tortillas in a single layer on the cooler side of the now-empty grill and cook until warm and lightly browned, about 20 seconds per side (do not grill too long or the tortillas will become brittle). As the tortillas are done, wrap them in a kitchen towel or a large sheet of foil.

To serve:

Separate the onions into rings and place them in a medium bowl; slice the bell peppers lengthwise into ¼-inch strips and place them in the bowl with the onions. Add 2 tablespoons reserved unused marinade to the vegetables and toss well to combine. Slice the chicken into ¼-inch strips and toss with the remaining 2 tablespoons reserved marinade in another bowl; arrange the chicken and vegetables on a large platter and serve with the warmed tortillas and desired accompaniements.


  • On chicken; if the breasts are the super thick monsters so often found these days, may be cut in 1/2 horizontally before pounding.
  • On heat level; the heat level is only mildly spicy. Up the heat with additional jalapeno and/or include ribs and seeds

        It was a perfect marinade with a great flavor. I choose to marinade whole breast for an hour and then drained and placed them in vacuum bags and then into the sous vide they went for 60 minutes at 145 degrees. A quick brown on the grill and on to the table. Mollie, I do believe that they were the best tasting cooked chicken breast I’ve ever tasted. Thanks.

          Ron, I’m glad you liked it! I love that marinade, but the Sous Vide probably had a lot to do with it, too! My sister just got one about 2 weeks ago. I’m going to suggest she do the same!

  1. Fajitas are something I love to feed to a crowd. I love putting out the meat and veggies, and then all of the goodies, so people can create their personal fajitas. Kind of makes a big mess, but everyone is happy! Love your marinade.
