Equipment

Ingredients

For Chicken Fajita Marinade

  • ¼ cup fresh lime juice
  • 2 tablespoons avocado oil, or other neutral flavored oil such as canola or vegetable oil
  • 1 teaspoon sugar
  • 1 teaspoon smoked paprika
  • 1 teaspoon granulated garlic powder
  • 1 teaspoon chili powder
  • 1 ¼ teaspoon kosher salt

For Chicken Fajitas

  • 4 teaspoons avocado oil, or other neutral flavored oil such as canola or vegetable oil
  • 1 ½ pounds chicken breasts (or thighs), sliced into 1-inch thick strips
  • 3 medium yellow onions, thinly sliced
  • 4 bell peppers (any color), thinly sliced

Instructions

Make the Chicken Fajita Marinade

  • Whisk the lime juice, oil, sugar, smoked paprika, garlic powder, chili powder and salt in a small bowl until the sugar is completely dissolved.
  • Add the marinade, chicken, and 1 tablespoon water to a 1-gallon zip-top bag or baking dish. Toss the chicken to coat, then press as much air out of the bag (if using) as possible, or cover with plastic wrap (if using a baking dish).
  • Refrigerate and marinate for 15 minutes, or up to 6 hours.

Cook the Chicken

  • Preheat a large cast iron skillet to medium-high heat. Remove the chicken from the marinade, shaking off any excess. Set the remaining marinade aside.
  • Add 2 teaspoons of avocado oil to the pan, then add the chicken in an even layer.
  • Allow the chicken to cook on one side for 5 minutes or until browned, then flip and cook 2-5 more minutes until cooked through. Remove from the pan and set aside.

Cook the Fajita Veggies

  • To the same pan (no need to wash it first), add 2 teaspoons of oil, along with the veggies.
  • Cook for 5-10 minutes, or until the vegetables are softened and begin to char, stirring frequently.
  • Add the remaining marinade to the veggies, along with the cooked chicken and bring to a strong simmer, stirring to coat. Simmer for 1-2 minutes for the marinade to reduce and for the flavors to combine.
  • Serve immediately with toppings of your choice.

Notes

  • A note about the nutrition information on this recipe, since we discard the marinade before cooking, it can be a little difficult to calculate. Nutrition information does not include toppings.
  • If you prefer to marinate the chicken without the fajita veggies, try my simple taco chicken marinade
