What Are Chicken Fajitas?

Fajitas are a classic Tex-Mex dish traditionally made with grilled meat, sautéed bell peppers, and onions, served with warm tortillas and your favorite toppings. The word “fajita” comes from the Spanish word “faja,” meaning “strip” or “belt,” referring to the thin strips of meat used in the dish.

Originally, fajitas were made with skirt steak, but chicken fajitas became popular in the 1980s as a lighter, healthier alternative. Today, chicken fajitas are a staple of weeknight cooking thanks to their simplicity, versatility, and incredible flavor.

Ingredients You’ll Need

Here’s everything you need for the best homemade chicken fajitas:

For the Chicken Fajitas:

1 ½ pounds (700g) boneless, skinless chicken breasts (or thighs)
1 red bell pepper, sliced
1 green bell pepper, sliced
1 yellow bell pepper, sliced
1 medium red onion, sliced
2 tablespoons olive oil

For the Marinade:

2 tablespoons lime juice (freshly squeezed)
3 tablespoons olive oil
3 cloves garlic, minced
1 teaspoon chili powder
1 teaspoon paprika (smoked or sweet)
1 teaspoon cumin
½ teaspoon oregano
½ teaspoon salt
½ teaspoon black pepper
Optional: pinch of cayenne for heat

Serving:

Warm flour or corn tortillas
Fresh cilantro (chopped)
Lime wedges
Toppings: sour cream, salsa, guacamole, shredded cheese, pico de gallo

Step-by-Step Instructions

1: Marinate the Chicken

In a large bowl or resealable bag, whisk together lime juice, olive oil, garlic, and all the spices. Add the chicken strips, toss to coat evenly, and let them marinate for at least 20 minutes (or up to 8 hours for deeper flavor).

2: Prepare the Vegetables

While the chicken marinates, slice your peppers and onion into even, thin strips. This ensures everything cooks evenly and quickly.

3: Cook the Chicken

Heat a large skillet (preferably cast iron) over medium-high heat. Add 1 tablespoon of olive oil. Once hot, add the chicken in a single layer and cook for 4–5 minutes per side until golden brown and cooked through. Remove the chicken from the skillet and set aside.

4: Sauté the Vegetables

In the same skillet, add another drizzle of olive oil if needed. Add the sliced peppers and onions. Sauté for 5–7 minutes until softened and slightly charred.

: Combine and Serve

Return the cooked chicken to the skillet and toss everything together until well coated and heated through. Squeeze fresh lime juice over the top for a zesty finish.

Serve the sizzling fajita mixture straight from the pan with warm tortillas and your favorite toppings.

Serving Ideas & Toppings

One of the best parts about fajitas is how customizable they are! Here are some ideas to make your meal shine:

How to Store & Reheat Chicken Fajitas

Reheat:

Stovetop: Warm in a skillet over medium heat until heated through.

Freeze:

You can freeze the marinated raw chicken or cooked fajita mixture for up to 3 months. Thaw overnight in the fridge before cooking or reheating.

Pro Tips for Perfect Fajitas

Use a cast-iron skillet – it retains heat beautifully and gives the chicken that irresistible sear.
Don’t overcrowd the pan – cook in batches if needed to keep everything crisp.
Marinate for flavor – lime juice and oil tenderize the chicken while spices infuse deep flavor.
Slice evenly – uniform strips cook evenly and look great in tortillas.
Squeeze fresh lime before serving – that citrus kick makes all the difference!

Variations to Try

1. Sheet Pan Chicken Fajitas

Bake everything on one tray for a hands-free, mess-free dinner. Simply toss chicken and veggies with marinade, spread on a sheet pan, and bake at 425°F (220°C) for 20 minutes.

2. Grilled Chicken Fajitas

For smoky summer vibes, grill marinated chicken and veggies over medium heat for 5–6 minutes per side. Slice and serve warm.

3. Slow Cooker Fajitas
