This easy chicken fajitas dish turns basic ingredients into a mouth-watering, diner-style feast your folks will ask for time and time again.

How To Cook Amazing Chicken Fajitas
- Cut the chicken right:
- Slice thicker chicken pieces sideways to make even strips about 1/2 to 3/4 inch thick that'll cook quick and evenly. This trick makes sure all your chicken finishes at the same time and stays super moist.
- Mix your marinade:
- Throw all marinade stuff in a bowl big enough for the chicken too. The lime starts working on making the meat tender while the oil carries all those herb and spice flavors into the chicken. Let it sit at least 30 minutes but overnight in the fridge works even better.
- Get that chicken golden:
- Your pan should be hot enough that it's almost smoking before the chicken goes in. This high heat makes a tasty brown outside while keeping the juices locked in. Don't touch the chicken for the first few minutes so it gets that nice crust.
- Let it rest:
- After cooking, pile the chicken up and cover with foil for about 5 minutes. This lets all the juices spread back through the meat instead of spilling out when you cut it. This little break makes the difference between dry and juicy chicken.
- Brown those veggies:
- Use the same pan so you get all those tasty bits the chicken left behind. The super hot pan turns the natural sugars in the peppers and onions into golden deliciousness you can't get with lower heat.
- Cut and dish up:
- Slice across the grain to make each bite more tender. Serve everything hot with warm tortillas and all your favorite toppings.

My favorite thing about cooking this dish is when the sliced peppers and onions hit that hot pan still coated with chicken goodness. That sizzle sound and amazing smell reminds me of my first fajita experience at our neighborhood Tex-Mex joint where they brought the hot iron pan right to your table. That memory makes me smile every time I cook this meal.
Tasty Sidekicks
Chicken fajitas go hand in hand with Mexican rice and beans for a full meal. These starchy sides balance out the big flavors while making everything more filling. Drink-wise, you can't go wrong with a classic margarita for grown-ups or some sweet horchata for everyone that goes really well with the spices.

Saving Extras
Keep the cooked chicken and veggies away from your toppings and tortillas to keep everything fresh. Once cooled, put your meat and veggie mix in sealed containers in the fridge for up to 3 days. When reheating, toss everything in a pan with a tiny bit of water to bring back the moisture. If you need longer storage, freeze the chicken and veggie combo for up to 2 months. Don't try freezing the toppings though as they'll turn mushy.
Planning Ahead
Get everything ready beforehand for quick dinner assembly on crazy nights. Cut your chicken and veggies up to two days early and keep them separate in the fridge. Mix up the marinade and store it alone until you're ready to add the chicken. Toppings like guacamole can be made a day ahead if you put some lime juice on top and press plastic wrap right on the surface to stop it from turning brown.
Swap-Out Options
Out of fresh jalapeños? Just use 1/4 teaspoon of cayenne or red pepper flakes instead. No limes? Lemons work fine or try orange juice for a different twist. Chicken thighs can replace breasts for an even juicier result. Want to skip the meat? Use portobello mushrooms or firm tofu with the same marinade and cooking steps for a tasty veggie version.
