Chicken Fajitas

There’s just something about the smell and sound of sizzling fajitas that always makes my mouth water. As much as I love ordering fajitas at a restaurant, making them at home has proven to be way more rewarding! Truly, I’ve yet to order chicken fajitas anywhere that are this juicy, tender, and loaded with savory flavor.

The best part? This recipe could not be any easier to make in just one pan. You just have to toss the chicken and veggies in a bowl (or bag) to marinate in the fridge, then you toss it all in a pan and cook to perfection in just a few minutes. I do recommend marinating the chicken and veggies for a full 4 hours to really solidify that bold flavor!

If you’re serving these skillet fajitas at a party, like on Cinco de Mayo, I recommend setting up a toppings bar. That way, your guests can make their perfect fajita just the way they like it! Just a few of my favorite toppings include limes, lettuce, cheese, avocados, sour cream and salsa. Oh, and you can’t forget the most important pairing – a margarita!

Storing and Reheating

If you happen to have any leftovers, you’re in luck! The chicken and veggies reheat like a charm. Just be sure to let everything fully cool to room temperature prior to storing in an airtight container in the fridge for 3-4 days. To reheat, I recommend tossing the chicken, peppers and onions right back into a skillet over medium-low heat until warmed through.

If you need to use your microwave, be sure to reheat everything for just 30 seconds at a time until warmed all the way through. You don’t want to overheat your chicken and risk drying it out.

Tips for the Best Chicken Fajitas

Get the very best skillet fajitas every time with these quick tips and tricks:

  • Let everything marinate. Sure, you can just season the chicken and veggies and call it a day. However, when you let it all marinate in the fridge for at least 20 minutes, you give the flavors time to develop and really settle in. I always marinate my chicken fajitas for a full 4 hours.
  • Warm your tortillas. The best way to make any store-bought tortilla (corn or flour) taste fresh is to toast it in a pan over medium-low heat for just a few seconds on each side.
  • Have fun with the toppings! Creating a big topping bar is always so much fun. Get creative with your toppings and be sure to comment below to let me know what you tried!
