This quick chicken fajita marinade delivers bold Tex-Mex flavor. Make it ahead or freeze with the chicken for easy weeknight fajitas in just 30 minutes.
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.
