Key Ingredients for Authentic Mexican Chicken Fajita Recipe

Chicken Fajita Marinade Ingredients

• Chicken Fajita Marinade: The marinade is key to the flavor of the chicken in this recipe, so be sure to marinate the chicken for at least 30 minutes, or up to 4 hours, for maximum flavor.
• Lime Juice and Zest: Fresh lime juice and zest add a bright, citrusy flavor to the marinade. Be sure to zest the limes before juicing them.
• Garlic: Fresh garlic adds a pungent, savory flavor to the marinade. Mince the garlic with a knife, or use a garlic press to save time. Fresh is best, but use garlic powder if you must.
• Spices: The combination of oregano, cumin, smoked paprika, cinnamon, ancho chili powder, and salt give the marinade a complex, smoky, and slightly spicy flavor. You can adjust the amount of chili powder to your taste, or substitute regular chili powder if you can’t find ancho chili powder.
• Chicken: Chicken breast is a lean and flavorful choice for fajitas. Cut the chicken into thin strips for even cooking. You can certainly use chicken thighs as well.
• Onions and Peppers: Thinly sliced onions and peppers add texture, color, and flavor to the fajitas. Use a mix of sweet and spicy peppers for a well-rounded flavor.
• Oil: Use a high-heat oil like avocado oil or vegetable oil to cook the chicken, onions, and peppers in the pan. Divide the oil evenly among the chicken and vegetables for even cooking.

Toppings for Authentic Mexican Chicken Fajita Recipe

Here are some suggested toppings for Fajitas de pollo:

1. Guacamole: A creamy and flavorful addition to your fajitas, guacamole is a classic Mexican condiment made with mashed avocado, lime juice, cilantro, and spices.
2. Pico de Gallo or Salsa: Fresh and vibrant, pico de gallo or salsa is a tomato-based condiment that adds flavor to your fajitas. Make your own by combining chopped tomatoes, onion, jalapeño, cilantro, lime juice, and salt.
3. Spanish Rice: Also known as Mexican rice, Spanish rice is a flavorful side dish made with long-grain rice, tomato sauce, onion, garlic, and spices like cumin and chili powder.
4. Refried Beans: A staple in Mexican cuisine, refried beans are made by cooking pinto or black beans with onion, garlic, and spices, then mashing them and frying them in oil. They’re a creamy and hearty addition to your fajitas.
5. Sour Cream or Mexican Crema: A cool and tangy topping, sour cream or Mexican crema balances out the heat of the fajitas. Mexican crema is a thinner and slightly sweeter version of sour cream commonly used in Mexican cuisine.
6. Shredded Lettuce: Fresh and crunchy, shredded lettuce adds texture and a healthy element to your fajitas.
7. Grated Cheese: A classic topping for fajitas, grated cheese adds richness and flavor to your dish. Cheddar, Monterey Jack, or a blend of Mexican cheeses are all great options.
8. Flour or Corn Tortillas: The perfect vessel for your fajitas, warm flour or corn tortillas are a must-have. Toast them in a dry skillet or on a griddle for added flavor.

How to Make the Best Easy Chicken Fajitas Recipe

Step 1 | Fajita Chicken Marinade

Start this easy recipe by combining all the marinade ingredients until you have a thick but pourable marinade. If necessary, add a bit more lime juice to thin it out. In a large bowl or freezer baggie, add the sliced chicken and the marinade, turning until all the chicken is coated.

Next, marinate the meat for at least 30 minutes on the countertop. Place the chicken in the refrigerator if you plan on marinating it for longer. If preferred, you can marinate the chicken up to 24 hours ahead. 

Step 2 | Prep fajita ingredients

While the chicken is marinating, prep the remaining vegetables by slicing the onions and peppers into thin strips.

Step 3 | Saute the veggies

In a large skillet, heat two tablespoons of oil over medium-high heat. Once hot and shimmering, carefully add the sliced onions and stir, sauteing them for 4-5 minutes until softened and starting to brown. 

Next, add the sliced peppers and turn them with the onions, sauteing for 4-8 minutes more until the ingredients are soft and caramelized. 

Step 4 | Saute or grill the chicken fajitas

Remove the onions and peppers to a plate and cover them with foil while you cook the chicken. 

Then, add an extra tablespoon of oil to the same pan over medium-high heat. Carefully add the chicken strips, careful not to crowd the pan. You may need to work in batches, quickly stir-frying the chicken for about 5-6 minutes until chicken is cooked. 

Step 5 | Combine the chicken and fajitas, then serve!

During the last minute of cooking, add the peppers and onions back into the pan, using tongs to turn and rotate the fajitas until they are combined with the chicken and heated through. Then, serve sizzling hot!

If you want restaurant-style sizzling and slightly charred fajitas, place the cast iron pan into your oven on its highest heat setting. Very carefully, add the hot fajitas to the hot pan and watch (and hear them) sizzle when you’re ready to serve this delicious dish! Serve with warm tortillas and more of your favorite toppings!

Variations & Substitutions

Vegetarian Fajitas: Make vegetarian fajitas with meaty portabella mushrooms, pinto or black beans, tofu, or a plant-based meat alternative. You may also want to increase the vegetables or add variety, like yellow and zucchini squash or broccoli. 

Swap or Add Protein: Serve a variety of meats or swap the chicken for shrimp or beef. If you’re making a combination, marinate each in separate containers. Remember only to saute shrimp until it becomes opaque. 

Spicy Fajitas: Sprinkle some cayenne pepper into the marinade for a little kick of heat, and add some chopped fresh jalapeño when sauteing the peppers.

Chicken Fajita Salad: Serve this recipe over a bed of lettuce or mixed greens to make it a refreshing and flavorful salad. You can even serve it over rice for homemade fajitas burrito bowls.
