Directions: Skillet Chicken Fajitas

Step 1: Marinate the Chicken
Start by preparing a marinade for the chicken. In a small bowl, mix together 2 tablespoons of cooking oil, minced garlic, ground cilantro, ground cumin, ground cayenne pepper, dried oregano, and kosher salt. Coat the chicken breasts in this mixture and let them marinate for at least 15 minutes. For best results, allow them to sit for up to 2 hours in the refrigerator.
Step 2: Heat the Skillet
In a large skillet, heat 1 tablespoon of cooking oil over medium-high heat. Allow the oil to become hot but not smoking.
Step 3: Cook the Chicken
Once the skillet is hot, add the marinated chicken breasts. Cook for about 5-7 minutes on each side, or until they are golden brown and cooked through. The internal temperature should reach 165°F (75°C). Remove the chicken from the skillet and let it rest for a few minutes before slicing it into strips.
Step 4: Sauté the Vegetables
In the same skillet, add the sliced red onions and bell peppers. Sauté for about 5 minutes, stirring occasionally, until the vegetables are tender and slightly caramelized. You can add a splash of water or broth if needed to deglaze the pan and add extra flavor.
Step 5: Combine and Serve
Return the sliced chicken to the skillet with the sautéed vegetables. Toss everything together to combine and heat through. If desired, squeeze fresh lime juice over the top for added brightness.
Step 6: Prepare the Tortillas
While the chicken and veggies are finishing up, warm the flour tortillas in a separate skillet or microwave. This will make them more pliable and delicious!
Step 7: Assemble Your Fajitas
Serve the chicken and veggie mixture on a platter with warm tortillas on the side. Let everyone build their own fajitas, adding their favorite toppings like salsa, guacamole, or sour cream.
Vegan & Vegetarian Swaps

If you’re looking to switch things up for a vegan or vegetarian option, consider these alternatives:
- Replace chicken with tofu or tempeh – Marinate and cook the same way as you would the chicken.
- Use black beans or chickpeas – For a protein-packed, plant-based filling.
- Substitute with portobello mushrooms – Their meaty texture is a great stand-in for chicken.
- Swap flour tortillas for corn tortillas – A gluten-free option that pairs wonderfully with fajitas.
Mistakes Even Pros Make
Even seasoned cooks can stumble when making skillet chicken fajitas. Here are some common pitfalls to avoid:
- Overcrowding the skillet – This can lead to steaming rather than sautéing, which affects the flavor and texture.
- Not letting the chicken rest – This can cause the juices to escape, resulting in dry meat.
- Skipping the marination step – Marinating the chicken infuses it with flavor, so don’t skip this important step!
- Using low-quality tortillas – Opt for fresh, high-quality tortillas for the best taste and texture.
Storage Pro Tips
After enjoying your skillet chicken fajitas, you may have some leftovers. Here’s how to store them properly:
- Store chicken and vegetables separately from tortillas – This will keep them from getting soggy.
- Use airtight containers – This helps maintain freshness and flavor.
- Refrigerate within two hours – For food safety, make sure to refrigerate leftovers promptly.
- Consume within 3-4 days – For the best quality, eat the leftovers within a few days.
- Reheat on the stove or microwave – Ensure everything is heated through before serving again.
Ask & Learn
Can I use frozen chicken for this recipe?
While it’s best to use fresh chicken for optimal flavor and texture, you can use thawed frozen chicken. Just ensure it’s fully thawed before marinating and cooking.
What toppings pair well with chicken fajitas?
You can enhance your fajitas with a variety of toppings such as sour cream, guacamole, fresh salsa, chopped cilantro, shredded cheese, or sliced jalapeños.
