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 platernrn”
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 lbs 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 to 12 small soft flour tortillas
For the Peppers
- 2 tablespoons vegetable oil
- 1 large red onion, sliced ¼-in (6-mm) thick
- 2 bell peppers sliced ¼-in (6-mm) 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-in (13-mm) 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 (60 ml) 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 (60 ml) 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 (13-mm) 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.

This is the best way to make grilled chicken breasts whether or not you are making fajitas. They are juicy and well seasoned and go great with the peppers and onion part of the recipe. Best part: grandkids love them too!
Heaven! This is the best fajita recipe ever! Fantastic easy recipe, I would never have thought of using lime zest instead of lime juice, but it tastes better and keeps the marinade thicker! Glazing the veggies with a little sugar is genius! Thanks, Jenn! I’m gonna have a party and serve this with margaritas and your Carne Asada!!
I made this recipe two days ago as written and both my husband and I absolutely loved it. I’ve made a few of your recipes and have never been disappointed. I used to question ingredients (the sugar on the bell peppers) but now I trust your recipes, don’t worry about the ingredients, and know that if it’s an ingredient you add it will simply work, because you’ve made the recipe, you know your flavors and you never disappoint.
Thanks 🙏 for sharing your knowledge with home cooks like myself.
The only change I made was the marinating time I didn’t have much time, I only marinated it for four hours and a half. It was delicious 😋 next time I will plan better and do the 12 hours.
❤️
Another terrific meal and I used up some extra grilled breasts. Makes a great, easy meal. Thanks again Jen!
Hi, I made this fajita recipe today and we really enjoyed it. I marinated overnight with a little extra oil and cilantro (I love cilantro). I cooked the chicken in the air fryer instead of the grill and it turned out great.
This was fantastic. The spices in the marinade were perfect. My husband, who is from Texas, was impressed.
Yet another FANTASTIC recipe! My son moves out this week and asked for the recipe. Sadly, he won’t be able to BBQ. What would be the best way to cook the chicken without a BBQ.
THANKS Jen!
Glad it was a hit! I’d use the oven or the stove to cook them inside. If you use the oven, I’d place them on a broiling pan and broil 4 to 6 inches from the heat for 5 minutes per side, or until chicken is done. If you use the stove (you’ll need to turn the oven on too), sear the chicken in an oven-proof sauté pan over high heat (for a min or two per side until browned) then finish it in a 350-degree oven for 5-10 minutes. Hope that helps!
This chicken recipe is fantastic! My 13 year old daughter gave it a “10” on a scale of 1-10, for deliciousness! I will definitely be making this again!
These fajitas were delicious! I believe they were close to being as good as my fav Mexican restaurant. I used chicken tenderloins, which I had on hand. I think I’ll try chicken breasts next time.
We prefer corn tortillas, and the microwave warming worked well. I usually warm them in a hot dry skillet, but this method was easier and delicious.
I always use a prepared fajita rub. This time I made your recipe. Loved it and easy to prepare
