Chicken Fajitas

Smoky grilled chicken, sizzling peppers and onions, and all the classic accompaniments—whip up chicken fajitas at home that rival those from your favorite Tex-Mex restaurant!
Chicken fajitas are a popular Tex-Mex dish with flavorful chicken strips served with sautéed onions and bell peppers. The chicken is marinated in a mix of warm spices, lime, and garlic, which helps tenderize the meat and boost flavor. Served with warm flour tortillas and toppings like guacamole, sour cream, salsa, and shredded cheese, fajitas are always a hit.
In restaurants, fajitas are often served on a sizzling cast iron plate for added flair. While it might be tricky to replicate that sizzling experience at home, my version is just as tasty, if not better! These fajitas are flavorful, customizable, and easy to prepare, making them perfect for weeknight dinners or casual get-togethers. Plus, leftovers are great in salads, tacos, burritos, and more.
“Amazing! These are by far the best fajitas! I may or may not have licked the plate”
What You’ll Need To Make Chicken Fajitas
- Chicken: You can use boneless skinless chicken breasts or chicken tenderloins for this recipe. If using breasts, they need to be pounded to an even thickness before marinating. Tenderloins do not require pounding, making them a a great time-saver.
- Vegetable oil: The base for the marinade. Also used to cook the peppers.
- Garlic: Adds a pungent, aromatic flavor to the marinade.
- Lime zest: Provides a bright, citrusy flavor to the dish without the risk of toughening the chicken, as lime juice would.
- Cumin, oregano, ancho chile powder, smoked paprika: This blend of spices adds warmth, earthiness, and a smoky flavor to the fajitas. Skip the fajita seasoning packet from the supermarket—it contains additives and isn’t nearly as tasty as what you can pull together quickly at home. If you’d like to add a little heat, include a generous pinch of cayenne pepper.
- Soft flour tortillas: The wrap for the fajitas.
- Red Onion & Bell Peppers: This classic fajita duo provide sweetness and crunch, adding a fresh, vibrant element to the fajitas. If you’re a spicy food lover, try substituting some of the bell peppers for jalapeño peppers.

Step-by-Step Instructions
First, pound the chicken breasts to an even 1/2-inch thickness. This helps tenderize the chicken and makes sure it cooks evenly. (If you’re 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 alter the texture of boneless skinless chicken breasts, making them tough and leathery. The zest of the lime imparts lime flavor without changing the texture of the meat.
Mash all of the ingredients together, then add the chicken to the marinade and place in the fridge for at least 8 hours or overnight—the longer you marinate, the more flavor your fajitas will have.
When you’re ready to grill, heat the oil in a large pan over medium-high heat. Add the peppers and onions.
Cook over medium-high heat until the vegetables start to brown. Add a splash of water to deglaze the pan, scraping up the brown bits, and keep cooking until the veggies are caramelized and tender-crisp. (This veggie mixture can be prepared up to 3 days ahead of time and reheated in the microwave.)
When you’re ready to serve the fajitas, preheat the grill. 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. Be sure to warm your tortillas before serving; warming helps to make the tortillas softer and more pliable, and it also enhances their flavor.

Ingredients
For the Chicken
- 1½ to 1¾ pounds chicken tenderloins or boneless, skinless chicken breasts
- ¼ cup vegetable oil
- 3 cloves garlic, minced
- 1 tablespoon lime zest, from 2 limes
- 1 teaspoon cumin
- ¾ teaspoon oregano
- ¾ teaspoon ancho chile powder
- ½ teaspoon smoked paprika
- 1 teaspoon salt
- 8-12 small soft flour tortillas
For the Peppers
- 2 tablespoons vegetable oil
- 1 large red onion, sliced ¼" thick
- 2 bell peppers, sliced ¼" thick
- ¼ teaspoon salt
- ½ teaspoon sugar
Optional Accompaniments For Serving
- Sour cream
- Guacamole, store bought or homemade
- Salsa, store bought or homemade
- Shredded cheese
- Chopped cilantro
Instructions
- (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 ½-inch thickness.
- 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.
- Clean the grill and preheat to high.
- 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 ¼ 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 ¼ 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.
- 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 ½-inch strips.
- Arrange the chicken and peppers on a serving platter. To warm the tortillas: stack 4 to 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.
- Make-Ahead Instructions: The onion and pepper mixture can be made 3 days ahead of time and reheated in the microwave.

It was moist and delicious! Made it for Cinco de Mayo and it was a hit! Great for summer barbecue parties.
I needed to make fajitas for a dinner party & these turned out perfectly! They are moist & delicious. Thank you for sharing!
2 quick questions: Is the oregano ground or dried leaves? And is the salt kosher or table? Thanks so much…every recipe of yours I have tried so far has been a winner! Keep them coming!
Hi Trish, For my recipes, salt is always table salt unless kosher is specified, and the oregano is dried leaves. Hope you enjoy!
I made these last night and OMG, they were delicious. I ended up marinating the chicken from late morning to early evening (about 8 hours). This is such an easy recipe to make and I will definitely make them again 🙂
Made this Grilled Chicken Fajita recipe last night and we loved it! I decided to make it at the last minute so I only marinated it for 3+ hours and the marinade still produced wonderful flavor and moist chicken. I will be making this again and again. Thanks.
Made these last night and we both just loved them!!! Made two changes—adjusted spices to what we both like and because we both needed a beef fix-I substituted beef for chicken! It was outstanding. Thank you for another addition to my menus.
This was the second time I made your chicken fajitas. The first time about a month ago, made exactly as recipe. Very very tender and moist,but our taste didn’t agree with the taste of cumin. This time only used half of the amount and they were excellent. Another fabulous recipe Thank you!!
This recipe sounds delicious! However, today and for the next couple of days is predicted to be very cold and extremely windy where I live. I know grilling would be ideal, but do you think broiling would still taste very good, and what do you think of adding a liquid smoke to the marinade?
Hi Joanne, Broiling will work and I’m sure a little liquid smoke would be delicious. 🙂
Jenn, thank you so much for the advice! This was absolutely scrumptious! I thought I had enough chicken breasts, but I had a package of chicken breasts and a package of the chicken thighs. I used them both since it was what I had, and they both were devoured. I used one teaspoon of Wright’s liquid smoke in the marinade. It was just right since I had the smoked paprika too. I was asked to make this again and I will! It was so simple and such a hit!
This was SUCH a huge hit last night!!! I have 2 teenagers so I always double whatever I make so there are left overs – let me tell you it was all gone within 24hrs! This is definitely a great go-to! The only debate over the dinner table was what was better – these or your Chipotle Chicken Quesadillas recipe, which I make all the time as well!
Thank you, thank you!!!
Hi! If I have to use a broiler instead of a grill, how long should I leave the chicken in for? Thanks!
Hi Audrey, The cook time should be about the same. 🙂
