This Easy Chicken Fajitas Recipe is loaded with juicy chicken, crisp bell peppers, and sweet onions tossed in a dynamite homemade fajita seasoning mixture. Fajitas with chicken are a great 30-minute meal to add to your meal plan. It's as easy to make as Steak Fajitas.
Preheat a cast iron skillet with 1 tablespoon of vegetable oil over medium-high heat.
In a small bowl, add the chili powder, cumin, garlic powder, paprika, oregano, salt and black pepper and stir to combine. Set aside.
Place the chicken breasts between two sheets of parchment or wax paper. Use a meat mallet to pound the breasts to an even 1/2" thickness.
Generously coat both sides of the chicken with the fajitas seasoning mix. Transfer to the preheated skillet and cook for 7-8 minutes per side, until the internal temperature reaches 165°F.
While the chicken is cooking, slice the peppers and onions.
Remove the chicken to a cutting board and let rest for 5 minutes. While resting, add the remaining vegetable oil to the skillet along with the peppers and onions. Cook until softened (approx. 4-5 min). While the vegetables are cooking, slice the chicken.
Add the chicken back to the pan, squeeze a lime wedge over the top and toss with the cooked peppers and onions.
