Grilled Chicken Fajitas

Tested & Perfected Recipes

These smoky chicken fajitas will rival those from your favorite Tex-Mex restaurant.

When I think of fajitas, what comes to mind is that sizzling, smoking-hot cast iron skillet from my favorite Tex-Mex restaurant. It’s hard (and, honestly, a little dangerous) to replicate that at home, but it’s possible to make fajitas that are just as good, if not better. I marinate and grill the chicken for a smoky, charred flavor, and then I sauté the onions and peppers on the stovetop until they caramelize and sweeten.

The ingredient looks long but don’t let that deter you. These fajitas are easy to make and you can do all of the prep ahead of time, so all that’s left to do at dinnertime is grill the chicken. Plus, they’re fun — perfect for getting the whole family sharing everything at the table.

How to make chicken fajitas

To begin, pound the chicken breasts to an even 1/2-inch thickness. This both tenderizes the chicken and ensures that it cooks evenly. (Note: If using chicken tenderloins, you can skip this step.)

Next, make the marinade by combining the oil, garlic, lime zest, ancho chili powder, smoked paprika, cumin, oregano, and salt right in a Ziplock bag (no dirty bowls!). Note that I don’t use lime juice in the marinade. I find that acidic ingredients change the texture of boneless skinless chicken breasts, making them tough and leathery. The zest of the lime imparts lime flavor without altering the texture of the meat.

Mash all of the ingredients together.

Then add the chicken and marinate for at least 8 hours or overnight.

When you’re ready to grill, heat the oil in a large pan over medium-high heat. Add the peppers and onions.

When you’re ready to eat, preheat the grill to high. Grill the chicken, covered, for 2 to 3 minutes per side.

Transfer the chicken to a cutting board and slice into strips. Arrange the chicken and peppers on a platter and set out with all the fixins, like guacamole, salsa, shredded cheese, sour cream and cilantro. Enjoy!

Servings: 4-6
Prep Time: 20 Minutes
Cook Time: 15 Minutes
Total Time: 35 Minutes, plus 8-24 hours to marinade

Ingredients

For the Chicken

  • 1-1/2 to 1-3/4 pounds chicken tenderloins or boneless, skinless chicken breasts
  • 1/4 cup vegetable oil
  • 3 cloves garlic, minced
  • 1 tablespoon lime zest, from 2 limes
  • 1 teaspoon cumin
  • 3/4 teaspoon oregano
  • 3/4 teaspoon ancho chili powder
  • 1/2 teaspoon smoked paprika
  • 1 teaspoon salt
  • 8-12 small soft flour tortillas

For the Peppers

  • 2 tablespoons vegetable oil
  • 1 large red onion, sliced 1/4" thick
  • 2 bell peppers, sliced 1/4" thick
  • 1/4 teaspoon salt
  • 1/2 teaspoon sugar

Optional Accompaniments For Serving

  • Sour cream
  • Guacamole, store bought or homemade
  • Salsa, store bought or homemade
  • Shredded cheese
  • Chopped cilantro

Instructions

  1. (Skip this step if using chicken tenderloins.) One at a time, place the chicken breasts in a sealable plastic bag and, using a meat mallet, pound to an even 1/2-inch thickness.
  2. Open a 1 gallon zip-lock bag and place in a medium bowl. Add the oil, garlic, lime zest, cumin, oregano, ancho chili powder, smoked paprika and salt into the bag. Mash the outside of the bag with your hands to blend the marinade together. Add the tenderloins or pounded chicken breasts and seal shut, releasing any air in the bag. Using your hands, massage the marinade into meat until evenly coated. Place the bag back in the bowl and place in the refrigerator (the bowl protects against leakage); let the chicken marinate at least 8 hours or up to 24 hours.
  3. Clean the grill and preheat to high.
  4. While the grill heats, cook the peppers. Heat the oil in a large skillet (preferably not non-stick) over medium-high heat. Add the sliced onions, peppers, salt, and sugar; cook, stirring occasionally, until the vegetables start to brown and a brown film forms around edges of the bottom of the pan, 8 to 10 minutes. Add 1/4 cup of water to the pan; scrape the bottom of the pan with a wooden spoon to release any browned bits. Continue cooking for 3 to 4 minutes, until the water is evaporated and the pan starts to brown again; add 1/4 cup more water and cook a few minutes more, until the vegetables are tender-crisp. Season to taste with more salt and sugar if necessary. Set aside.
  5. Oil the grates on the grill. Grill the chicken, covered, for 2 to 3 minutes per side. Do not overcook. Let the chicken cool slightly, then transfer to a cutting board and cut into 1/2-inch strips.
  6. Arrange the chicken and peppers on a serving platter. To warm the tortillas: stack 4-6 tortillas on a plate and cover them with a damp paper towel, then microwave for 30 seconds to 1 minute. Repeat with the remaining tortillas. Serve with the chicken, peppers and optional accompaniments.
  7. Note: The onion and pepper mixture can be made ahead of time and reheated in the microwave.

Reviews & Comments

  • Excellent! The flavors are spot on.
    I prefer to wipe off some of the thick marinade before grilling; I thought the flavors were a little strong when I grilled it with a lot of the marinade still on it. Sometimes I grill whole jalapenos along with the chicken, or add some to the bell peppers for some heat.

Just have to throw the marinade together before going to work and husband does the grilling. Excellent go-to recipe for easy weeknight meal!

  • Hi. I love this recipe. I’m looking for a way to make this during our camping trip next week.
    Can I cook this chicken using a cast iron skillet after it is placed in the marinade? Can I cook the chicken in a foil packet with the vegetables? Thank you for your great recipes!

    • Hi Patty, I think either should work. Obviously, if you cook them in a foil packet they won’t brown on the outside like they would in the skillet. Hope you have fun camping!

  • Hi Jen! We love your recipes and especially like the chicken fajitas. In fact, we’re having a birthday gathering for my husband and would like to make this for our guests. I would really like to make this ahead of time and then just reheat it. In looking at your response to a similar question you say the peppers and the chicken can be reheated in a 325 oven. This sounds perfect, but how long does it take for the chicken to be heated this way and not overcooked? Also want to clarify that I should wait to slice the chicken until after I take it out of the oven? Thanks so much!

    • Hi Judy, So glad you like the recipes! I’d guesstimate that the chicken will need about 15 or so minutes to heat up (but I’m not 100 percent sure so give yourself some breathing room). And, yes, I’d wait to slice them after reheating. Hope your husband has a great birthday!

      • Thanks so much for the response. The 15 minute guesstimate was spot on! This worked perfectly, and the only thing I had to worry about once the party started was to make sure the margarita pitcher was full. Of course, we used your recipe and had 3 pitchers of margaritas mixed and in the fridge before the party! Also made the restaurant style salsa, salsa verde, Mexican rice, and black bean and corn salad with honey vinaigrette. Everything was a hit and you now have a few more fans! Everyone loved your recipes!

    Jen, this and many of your recipes have been such a hit in our house. My boys are learning fast, enjoying cooking and are nearing catering independence before heading off and back to uni in Sept. If they eat out, they often say, it’s not as delicious as yours Mum! I do remind them it’s not mine but my favourite recipe source, “the American Lady”.

  • I cooked the chicken in a skillet and not on the grill. The chicken turned out dry because I overcooked it, but the vegetables were so yummy because of the sugar/water cooking technique. I usually have cherry tomatoes on hand so I throw them in the mix instead of a red pepper. Would you provide some directions for cooking the chicken on the stovetop?

  • I’ve made this recipe several times and always comes out excellent. I was pressed for time on an occasion and resorted to a package of fajita seasoning mix and boy my kids could tell the difference. They stated the liked the other recipe, which is this one! I find it helpful to use a non-stick frying pan to brown and carmelize things – much for difficult with a non-stick pan. Works great for this recipe as you are adding water to the pan after browning the vegetables.

    This recipe is a keeper and the only one I will ever use for chicken fajitas.

The vegetables are my favorite aspect of this dish and I usually double the amount. Oftentimes, when we feel like a vegetarian option, I make the vegetables alone, with a side of rice and black beans. Delicious.

  • My family loves these fajitas! I’ve made them several times now, and I do make a couple of adjustments: I like to make a double batch of the marinade, split it between two large ziploc bags, and fill one bag with the sliced onions and peppers, and the other with sliced chicken breasts. Additionally, I go ahead and add the fresh lime juice to the marinade along with the zest, and shorten the marinating time to 3-4 hours. This is a delicious and easy dinner– very kid friendly as well.

  • SO. GOOD. These taste exactly like what you get in a restaurant and are so easy to make! The smoked paprika is the ingredient that really gives them that restaurant smell and taste. I made in my kitchen using a cast iron pan, and I used chicken tenders, so I skipped the pounding. I served with Jenn’s Restaurant Salsa — both with chips before the meal and some people used as a sauce in their fajitas. This is now in my permanent rotation!

  • Made these for visiting family. Put the chicken in the marinade the night before family was due to arrive, but due to travel issues, they arrived too late for dinner, so the chicken actually sat in the marinade for 48 hours. They were incredible! In fact, the next morning after dinner, my 12 year old great nephew was overheard telling a friend about the awesome chicken fajitas he had for dinner the night before. Congrats on impressing a 12 year old! I served the salsa verde and the restaurant style salsa with these and they were also a huge hit. In fact, my niece took all the recipes to serve to her inlaws when they visit next month.
