How to Make Chicken Fajitas in a Cast Iron Skillet
Add the lime zest, juice and 1 tablespoon of the olive oil to a small bowl.
Whisk to combine, then mix in the fajita seasoning to create a rub.
Add the chicken in a large bowl and pour the chicken fajita seasoning over the top, then toss to coat the chicken. Marinate for 30 minutes in the fridge.
Heat a cast iron or large skillet to medium high heat. Add half the remaining olive oil and butter.
Sauté the chicken on all sides until cooked through and reaches an internal temperature of at least 165°F when checked with a meat thermometer.
Remove the chicken from the pan and set aside, covered to keep warm.
Add in the remaining olive oil and butter, along with the peppers and onion.
Sauté until the onions are soft and have become slightly charred and caramelized.
Add the chicken back in and toss to combine. Serve with a squeeze of lime juice and chopped cilantro.
Can I Freeze Leftover Fajitas?
Absolutely! Just place leftovers in a freezer-safe bag or other type airtight container, labeled with the date they were prepared, and stick them in the freezer for up to 3-4 months.
To thaw, all you have to do is place the bag or container in warm water until it's loosened up enough to transfer them to a skillet for reheating.
How Many Carbs are in Chicken Fajitas without Tortillas? Are Fajitas Good for Keto Diet?
There are only 4 net carbs in one serving of chicken fajitas without serving them wrapped in a tortilla.
If you were to add a flour tortilla, that would drive up the carb count to over 50 grams per serving! Fajitas with corn tortillas have over 45 grams of carbs.
That savings in carbs make chicken fajitas an excellent choice for those on Keto or low carb diets. Plus, because this recipe uses a homemade chicken fajitas seasoning, you aren't adding a bunch of preservatives or added sugar, which makes them even heathier!
How Much Chicken Fajita Per Person?
If you are planning a dinner where fajitas are the main protein, you will want to consider having 4-6 ounces of chicken per person. Just like with any other meal, some will eat more than that, some will eat less. You'll also either serve this over a salad, Keto friendly tortilla, cauliflower rice or with a vegetable or salad on the side.
What Cut of Meat is Chicken Fajita?
This is totally a personal preference. You can use chicken breasts or thighs. But there are a few things for you to consider...
Chicken breasts are leaner. Since they have less attached fat, they require less work when slicing them into strips. They are also a denser cut than thighs and they shrink less when cooked, which could make a difference if you are making them for a crowd.
Thighs have more flavor and are always super tender. Because of the fat that runs through the thigh, you never have to worry about dried out or tough strips of chicken. Dark meat typically takes longer to cook but you can counter that by using thinner strips.
Either way you go, both are great choices and will work great when searing in cast iron.
If you prefer beef, try these beef fajitas in crockpot. They're the ultimate "set it and forget it" fajitas, cooked low and slow!
How Do you Eat Fajitas without Tortillas?
You can eat them just as you would pepper steak or grilled chicken breast. If you want, you can serve them over a bed of Mexican Cauliflower Rice or even over simple salad with some Chipotle Ranch Dressing drizzled over the top.
What Toppings Go on Fajitas?
One favorite way to serve these fajitas is to set up a fajita station and let everyone dress their own. Toppings for you to consider are:
- Sliced avocado or fresh Guacamole
- Chopped fresh cilantro
- Lime wedges
- Sliced fresh or pickled jalapenos
- Diced tomatoes or salsa
- Chopped lettuce
- Various cheeses-3 Cheese Mexican blend, pepper jack, cheddar, crumbled cotija
- Pico de Gallo
What is the Best Way to Cut Chicken Breast for Fajitas?
The reason I decided to slice the chicken first, is so the marinade/spices can cover more surface area, giving the chicken a bit more flavor. When doing this, you'll want to slice the breasts against the grain to help keep them tender. But there is another way you can cook your chicken if you’d like.
You can leave the breasts whole and marinate accordingly. Then sauté the chicken until cooked through, then slice the chicken against the grain and serve with the cooked veggies.
