What Makes Cast Iron Fajitas So Good?

We love using our cast iron skillet to make many recipes. Cooking these fajitas in high heat helps to retain the heat to give the the meat the best sear.

It also gives the fajitas the best authentic flavor so we can make our favorite Tex-Mex flavor right at home. Which saves time and money for my large family.

These cast iron skillet chicken fajitas are everything you want in a quick meal that is bursting with smoky flavor, juicy, colorful, and cooked so tender.

Ingredients

How to Make Fajitas in an Cast Iron Skillet

Step 1 – Add all the thin strips of chicken ingredients to a large bowl and toss to thoroughly coat the chicken with the oil and the seasonings.  Let the chicken marinade for at least 30 minutes (or overnight).  

Step 2 – Preheat a cast iron skillet on a grill over medium high heat. Once the skillet is heated through, add in 1 tablespoon of olive oil to the pan. 

Step 3 – Add in the peppers and onions and season them with the chili powder, cumin, salt and pepper. 

Step 4 – Sauté the peppers and onions for 4-5 minutes until tender. Remove from the pan to a separate plate. 

Step 5 – Add the seasoned chicken to the pan and spread it out into a single layer. Allow the chicken to cook without moving it for 3-4 minutes until it’s seared. 

Step 6 – Then toss the chicken and continue to cook until the juicy chicken is cooked through (internal temperature of 165 degrees F). 

Step 7 – Stir the peppers and onions back into the pan. Top with the lime juice and stir to coat in the juice for approximately 1 more minute. 

Step 8 – Warm the tortillas on the grill for 1 minute per side by placing them directly on the grill and watch them closely so they do not burn. Serve over the tortillas topped with chopped cilantro, fresh lime juice and enjoy!

Recipe Tips

• Prepare Skillet – Before placing the veggies and chicken in the skillet, make sure it is hot. This will give them meat the best sear.
• Batches – If you are cooking for a large crowd, you may need to cook the fajitas in batches. You do not want to overcrowd the pan so that everything cooks evenly.
• Slicing Chicken and Veggies – Make sure that the chicken and vegetables are sliced about the same size. This will help to cook them evenly and about the same time.

Variations Ideas

• Change Meat – We used chicken in this recipe but you can also make it with flank steak, skirt steak or shrimp.
• Skip Meat – If you prefer make a vegetarian fajita loaded with peppers, onions, mushrooms and zucchini.
• Low Carb Option – This chicken fajita recipe taste great served over rice instead of made into tacos in a corn tortilla or flour tortilla. We love making a fajita bowl with our leftovers.

What to Serve with Fajitas

Fajitas make the best meal but adding your favorite side dishes and toppings makes them taste even better. Serve the fajitas sizzling hot for a restaurant quality meal.

• Toppings – Serve with your favorite fajita toppings: shredded cheese, salsa, guacamole, pico de gallo and sour cream! 
• Rice – Add of a side of Spanish Rice Recipe, Chipotle Cilantro Lime Rice Recipe or Mexican Rice.
