Ingredients to make fajitas

Homemade fajitas seasoning — while you can use store-bought pre-mixed seasoning, to make your own, all you need is chili powder, cayenne powder, paprika, cumin, black pepper, and salt. These are pantry staples, so I always have them on hand. I like making my own as there aren’t any filler ingredients added to them or additional sugars.
Oil — I use olive oil to saute my ingredients, but you can use a different oil, such as avocado oil.
Garlic — I like to use freshly minced garlic instead of garlic powder for this skillet chicken fajitas recipe.
Chicken breast — I like using free-range organic chicken with no antibiotics or added hormones.
Bell peppers — I use a mixture of red, yellow, and green bell peppers. It’s like eating the rainbow! However, you can use whatever bell pepper you prefer. Keep in mind that red bell peppers are the sweetest, then they get less sweet from orange, yellow, to green. Use all red bell peppers if you want the sweetest results!
Onion — I use a medium onion, but feel free to use more or less. You can use yellow, sweet, or even red onions.
Salt and pepper
Fresh lime juice for garnish

Instructions to make Fajitas in a skillet

This easy chicken fajita skillet recipe is cooked on your stovetop. It’s a one-pan meal with plenty of protein and veggies, and it is super easy to make.

Slice the chicken into long strips (about the same length as the peppers and onions). Having thin slices helps them cook faster and more evenly.
Allow the chicken to marinate in fajita seasoning for 15 to 20 minutes. You can also let it marinate longer if you are meal prepping your meat in the morning for a quick evening meal.
Cook the chicken thoroughly over medium-high heat and then remove it from the skillet.
Next, cook the veggies. If you prefer crisp veggies, cook them a couple of minutes less than the recipe calls for. Add a minute or two if you like the peppers and onions to be softer.
Add the chicken back to the skillet to combine with the veggies, and then serve them up!

If you have a cast iron skillet, cooking the meal in it will produce the flavor of a grill without having to sit outside over hot flames.

You have a couple of options for serving this meal.

You can eat the chicken and veggies as is, or wrap everything in a flour tortilla or corn tortilla. If you omit the tortillas, this dish is gluten-free and low-carb.

Either with or without the tortilla, you can add any toppings that your family enjoys. Setting up a fajita bar is a great way to serve a crowd. Another benefit is, there will be enough choices to please everyone.

Recipe tips

If your chicken was frozen, thaw them completely and pay them dry with some paper towels before seasoning. This helps the oil and seasoning stick better to the chicken.
If you’re worried about overcooking your chicken, use a meat thermometer to check the internal temperature of the chicken breasts. Once they reach 160F degrees, it’s cooked and ready to be eaten.
If you want to double or triple this recipe, you can cook them in batches so they cook evenly. You don’t want to overcrowd the skillet too much as the ingredients will steam instead of sear.
Use a well-seasoned cast-iron skillet for best results. A cast-iron skillet gives you the best char on the chicken and bell peppers.
