Description
For these grilled chicken fajitas, you’ll quickly marinate the chicken in a garlic lime marinade and that’s all it needs to transform it into a stellar fajita filling. Just add guac, cheese, and grilled veggies and call this dinner in under 30 minutes!
Ingredients
For the fajitas:
- 1/3 cup freshly squeezed lime juice
- 7 tbsp canola oil, divided
- 3 cloves garlic, minced or pressed
- 1 tbsp Worcestershire sauce
- 1 1/2 tsp brown sugar
- 1 jalapeño, seeded, ribbed and diced
- 1 1/2 tbsp minced fresh cilantro
- 1 tsp salt
- 3/4 tsp pepper
- 1 1/2 lbs boneless, skinless chicken breasts (6 halves total), pounded to about 1/2-inch thick
- 1 large red onion, sliced into 1/2-inch thick slices, rings not separated
- 2 large bell peppers, stemmed, quartered and seeded
- 8-12 (6-inch) flour tortillas
Toppings for serving:
- Shredded cheddar or Monterey jack cheese
- Guacamole
- Sour cream
- Scallions, sliced
- Extra cilantro, chopped
Instructions
- Whisk the lime juice, 4 tablespoons of the canola oil, garlic, Worcestershire sauce, brown sugar, jalapeño, minced cilantro, salt and pepper together in a medium bowl. Reserve ¼ cup of the marinade and transfer the rest to a large, shallow casserole dish. Add the chicken to the dish, cover the dish tightly with plastic wrap, and refrigerate it for 15 minutes.
- Meanwhile, heat the grill to high. When the grill is hot, brush both sides of the onion slices and peppers with 2 tablespoons of the oil. Turn two of the burners down to medium, keeping the third on high. Brush the grill grates with the remaining tablespoon of oil.
- Place the chicken (without the marinade, which you can discard now) on the hot end of the grill. Place the onions and peppers on the medium side of the grill. Cook the chicken for 3-4 minutes per side, until nice grill marks emerge and it is cooked through (165° F). Flip the onion slices (a spatula helps here rather than tongs) and peppers once the bottoms have started to char and cook on the other side until slightly charred as well. Remove the chicken and vegetables from the grill and keep them warm on a platter under foil. Turn the burners back to high and toss the tortillas on the grill for 20 seconds on each side until they are warmed and starting to char. Remove them from the grill and keep them warm between two clean kitchen towels.
- Add the reserved ¼ cup marinade to a large, shallow bowl. Separate the onion slices into rings and add them, along with the peppers to the marinade. Slice the chicken on the diagonal and add the chicken to the bowl as well, tossing everything to coat well with the marinade. Serve the onions, peppers, and chicken on a large platter alongside the suggested toppings for serving.

This is my favorite grilled fajita recipe, too! If I hadn’t already been in love with CI, I would have been after this.
These fajitas are the absolute best, it was the first meal we made when the weather got warmer!
