This chicken fajitas recipe always makes the most tender, juicy, flavorful chicken fajitas that are loaded with flavor, and it is so easy to make!

We’re cooking up one of our favorite weeknight meals in the Chili Pepper Madness kitchen tonight, my friends. Would you believe me if I told you it’s simply chicken and vegetables?

Healthy chicken and veggie dinners don’t need to mean “boring and flavorless” when you bring in a powerhouse of seasonings to marinate the chicken and combine with them with sweet and spicy peppers.

We’re talking Homemade Chicken Fajitas, and I already know you are going to love them. This might just be your new favorite recipe.

These easy chicken fajitas are huge on flavor. All you need are a simple yet powerful selection of seasonings, a bit of oil and lime juice for a chicken fajita marinade that results in tender, juicy chicken every single time.

Just sear them up in a pan along with your selection of sweet bell peppers and onions, some spicy jalapeno peppers if you’d like (I sure do!), and serve them up on warmed tortillas with your favorite fajita toppings.

Talk about delicious. And easy! This goes into my favorites collection because they’re so easy to make. I hope you love them as much as we do.

Let’s talk about how we make chicken fajitas, shall we?

Recipe Tips & Notes

  • Homemade Fajita Seasonings. As a time saver, use this fajita seasoning recipe to make your fajita seasonings ahead of time. This way, you can simply scoop out a couple tablespoons, mix with oil, water and lime juice, then marinate your chicken anytime. Or just use it as a dry rub and sear the chicken for even quicker fajitas.
  • Fajita Marinade. I use this chicken fajita marinade all the time, but it’s great for other proteins as well, like for steak fajitas or shrimp fajitas. It’s also great for vegetables or even marinating tofu or veggie based meats for vegetarian fajitas. Try marinating the bell peppers with the marinade. Great stuff! Huge flavor builder, and the marinade also helps to tenderize the meats.
  • Serving Chicken Fajitas. Fajitas are basically big chicken tacos, so you can pile on any and all of your favorite toppings. Toss on some of your favorite salsa, like pico de gallo, some spicy guacamole, diced tomatoes, fresh chopped herbs. I always go for a few dashes of hot sauce. Gotta spice things up, right?

That’s it, my friends. I hope you enjoy my chicken fajitas recipe. Let me know if you make it. I’d love to hear how it turned out for you. Keep it spicy! Fajita night!
