Make a sizzling skillet of chicken fajitas for your next weeknight meal. This crowd-pleasing dinner comes together in a single pan, made with chicken thighs, onion, bell pepper, and a simple homemade seasoning blend.
Fajitas are the star of any Tex-Mex restaurant visit. You can hear that hot skillet sizzling from across the room. Why not recreate that experience in your own kitchen? These skillet chicken fajitas are surprisingly easy to make at home, and come together in a single cast iron skillet.
These chicken fajitas are made with chicken thighs for extra flavor and juiciness (but can also be made with chicken breasts). Onion and bell pepper are sautéed with minced garlic and a simple blend of spices. All you need is a stack of warm flour tortillas and you're ready to dig in.
Serve these skillet chicken fajitas for a quick weeknight family meal. They can be served on their own or with your favorite taco toppings, like sliced avocado, guacamole, salsa, pico de gallo, and sour cream.
Ingredients and substitutions
- Chicken thighs - For this recipe, you'll need one pound of boneless, skinless chicken thighs. Can be substituted with chicken breasts if desired.
- Olive oil - Can be substituted with your favorite cooking oil you have on hand.
- Bell pepper - Any color of bell pepper works in this recipe (green, red, yellow, or orange). I suggest choosing two colors for added visual appeal.
- Onion - White or yellow onions work well in this recipe.
- Garlic - I highly suggest mincing your garlic fresh for best flavor.
- Seasoning - Cumin, chili powder, paprika, salt, and red pepper flakes. Spices can be substituted with store bought fajita seasoning or taco seasoning if needed (the two are very similar, but taco seasoning is generally spicier, containing more chili powder. Fajita seasoning usually contains more cumin).
- Cilantro - If you dislike cilantro, it can be omitted or substituted with parsley.
- Lime - One lime is squeezed over your fajitas just before serving.
- Tortillas - Use your favorite brand and style. I suggest 6-inch flour tortillas for fajitas.
What pan is best for fajitas?
I recommend using a large, 12-inch cast iron skillet for fajitas. This size has plenty of surface area for cooking your chicken and veggies separately, giving them a nice char.
Plus, using a cast iron pan adds that restaurant quality flavor and feel. Cast iron retains heat well, ensuring your fajita ingredients don't get cold before your skillet makes it to the dinner table.
Here's the pan I use in the photos:
If you don't have a cast iron pan on hand, a stainless steel sauté pan will work just fine.
Can I use chicken breasts?
Yes, this recipe will work using chicken breasts instead of chicken thighs. Keep a close eye on your chicken as it cooks, and remove it from the pan as soon as it reaches 165 degrees Fahrenheit. Chicken breasts are low in fat and can quickly dry out when overcooked, so it's important to keep an eye on them while cooking.
Why are chicken thighs better?
I like to use chicken thighs because they're a little fattier, which adds more flavor. Chicken thighs are also more forgiving when cooking, meaning they don't dry out quite as fast as chicken breasts do. They're also generally a little cheaper and budget-friendly when compared to boneless, skinless chicken breasts.
