For the best skillet chicken fajitas, keep these tips in mind:
- Use a cast iron skillet for even heat distribution and the perfect sear on the chicken and vegetables.
- Make sure your skillet is hot before adding the chicken to ensure a nice, golden crust.
- Don’t overcrowd the skillet. Cook in batches if necessary to avoid steaming the ingredients.
- Let the chicken rest for a few minutes before slicing to retain the juices.
The most important tip is to not rush the cooking process. Allowing each component to cook properly ensures the flavors meld beautifully, giving you that authentic fajita taste.
Step-by-Step Instructions
Preparing the Ingredients
Start by slicing the chicken breasts into thin strips. Then, slice the bell peppers and onion into similar-sized strips. Mince the garlic cloves and set everything aside.
Cooking the Chicken and Vegetables
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the chicken strips and season with half of the chili powder, cumin, smoked paprika, salt, and pepper. Cook until the chicken is browned and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set aside.
In the same skillet, add the remaining olive oil. Toss in the sliced bell peppers, onion, and garlic. Season with the remaining spices and sauté until the vegetables are tender and slightly charred, about 5 minutes.
Assembling the Fajitas
Return the cooked chicken to the skillet with the vegetables. Stir everything together so the flavors can meld. Warm the tortillas in the microwave or a dry skillet, then fill each with a generous scoop of the chicken and pepper mixture.
