Ingredients Notes

The beauty of Chicken Fajitas lies in their simplicity and the fresh, bold ingredients that make them shine. Let’s take a closer look at what you’ll need:
The star of the dish is chicken. Both boneless, skinless chicken breasts and thighs work well here. Breasts are leaner, while thighs bring a bit more juiciness and flavor.
Bell peppers are essential for that signature fajita flair. Choose a mix of red, yellow, and green peppers for a colorful presentation and a balance of sweetness and crunch.
Onions add depth and sweetness to the dish as they caramelize during cooking. Yellow or white onions work best, but red onions can add a slightly sharper flavor.
The fajita seasoning ties everything together. You can use a store-bought mix for convenience or make your own with chili powder, cumin, paprika, garlic powder, and a pinch of cayenne for heat.
For cooking, a good-quality cast-iron skillet is ideal. It retains heat well, ensuring you get that beautiful char on the chicken and veggies.
How To Make This Chicken Fajitas Recipe

Making Chicken Fajitas is as straightforward as it gets. With just a few steps, you’ll be on your way to a restaurant-quality meal at home.
Start by prepping your ingredients. Slice your chicken into thin strips, and do the same with the peppers and onions. Keeping the slices uniform ensures everything cooks evenly.
Heat a large skillet over medium-high heat and add a drizzle of oil. Once hot, add the chicken strips, seasoned generously with your fajita seasoning. Let them cook undisturbed for 3-4 minutes to develop a golden-brown crust before flipping.
Once the chicken is cooked through, remove it from the pan and set it aside. In the same skillet, toss in your peppers and onions. Allow them to cook until they’re tender and slightly charred, about 5-7 minutes.
Return the chicken to the pan and toss everything together. This step allows the flavors to meld while ensuring everything is heated through.
Serve your fajita mixture immediately with warm tortillas, a dollop of sour cream, guacamole, or your favorite toppings.
The entire process takes less than 30 minutes, making it one of the quickest and most satisfying meals you’ll whip up all week.
Storage Options
If you have leftovers (a rare occurrence!), Chicken Fajitas store beautifully for easy meals later in the week.
Transfer the fajita mixture to an airtight container and refrigerate for up to 4 days. The flavors will continue to develop, making leftovers even tastier.
To freeze, let the fajitas cool completely before placing them in a freezer-safe container. They’ll keep for up to 3 months. Thaw in the fridge overnight before reheating.
For reheating, use a skillet over medium heat to revive the flavors and texture. Microwaving works too, but the veggies may lose some of their charred edges.
Variations and Substitutions
Chicken Fajitas are incredibly versatile, and there are countless ways to tweak this recipe to suit your preferences.
For a vegetarian option, swap the chicken for firm tofu or hearty portobello mushrooms. Both absorb the fajita seasoning beautifully and bring their own unique textures to the dish.
Want to add more protein? Throw in some black beans or chickpeas for a plant-based protein boost.
If you like it spicy, add sliced jalapeños or a dash of hot sauce to the skillet. A sprinkle of crushed red pepper flakes can also amp up the heat.
Try experimenting with different seasonings. A smoky chipotle seasoning or a splash of lime juice at the end can add a new twist to the classic fajita flavor profile.
For a low-carb option, skip the tortillas and serve the fajita mixture over cauliflower rice or a bed of greens for a fajita salad.
No matter how you make them, these Chicken Fajitas are sure to become a favorite in your recipe rotation. With their bold flavors and endless customization options, they’re a meal you’ll come back to time and time again. Enjoy!
