These Grilled Chicken Fajitas are packed with flavor for an easy, healthy meal! The chicken is flavored with a homemade marinade, then grilled to perfection.

I am, and always have been, really big on seasonal foods. I try to always enjoy the best of what each season has to offer. Summer, fortunately, doesn’t just have great food. It also provides us with — what I affectionately call — grilling season.

You know what I mean. There is just something special about being outside, sun on your face, and the smell of burgers on the grill! It is special enough that it must have its own season. So, I am officially declaring grilling season open! It’s here!

In honor of warmer weather and sunny skies, I decided to make a big pile of piping hot homemade chicken fajitas! These fajitas are a game changer.

They take basic ingredients like chicken, peppers, onion, lime, cilantro, and garlic and turn them into something really special. The key is the fajita marinade! Instead of reaching for a packet of seasoning or the bottled stuff, we make our own.

Chicken Fajitas Ingredients 

This recipe is split into two parts: the marinade and the fajitas themselves. To make the BEST chicken fajita marinade, you’ll need:

• Olive oil
• Red onion
• Fresh cilantro
• Jalapeño
• Lime juice
• Garlic
• Brown sugar
• Salt and pepper

And for the rest of the recipe, you’ll need:

• Chicken breasts
• White onion
• Bell pepper
• Cherry tomatoes
• Corn tortillas  

Can I Make This Recipe Low-Carb? 

Yes, you can! Use homemade Zucchini Tortillas instead of corn tortillas for a lower carb fajita. 

How to Make Grilled Chicken Fajitas 

Grab some limes, garlic, jalapeños, red onion, fresh cilantro and a couple other pantry staples and get to work! Here is how we make these easy chicken fajitas: 

1. Combine the chicken fajita marinade ingredients in a large plastic bag, and add some sliced chicken breast.
2. Toss the mixture around a bit to make sure everything is nice and covered.
3. Now comes the hard part. The waiting. Let the chicken marinade at least 8 hours.
4. After your chicken has marinated, it’s time to prep your veggies. I sliced an onion, bell pepper and threw in some cherry tomatoes, for good measure.
5. Drizzle or spray a little olive oil and salt and pepper over the veggies to give them a little extra flavor.
6. Heat your grill to medium heat and add your chicken breast, cook on each side 2-3 minutes or until golden brown and juicy.
7. Remove chicken from heat and add the vegetables, grill until lightly charred.

Grab some warm corn tortillas and pile the grilled chicken and veggies as high as you’d like! Garnish with a lime wedge and some cilantro for the perfect healthy dinner. 

What to Serve with Chicken Fajitas 

These jalapeño lime chicken fajitas are pretty impressive on their own. But if you pair them with one of the following sides, you’ll have a real fiesta on your hands! 

• Avocado Bacon Dip
• Jalapeño Ranch Dip
• Seasoned Black Beans 
• Roasted Tomatillo Salsa
• Lima Bean Salsa

Tips for Making the Best Chicken Fajitas 

• If you feel like living on the wild side, you can throw the juiced lime peels in with the marinade to give it a little extra zing.
• You can put the chicken in the marinade in the morning before work. If you want to give it lots of extra time to soak up that jalapeño lime goodness, you can do it the night before. Either works fine.
• I always recommend using a meat thermometer to ensure that the chicken is completely cooked through. Cooking times listed may vary depending on the thickness of your meat.
