How to make chicken fajitas in a skillet
- Marinate. Whisk the marinade in a bowl or zip-top bag, add the chicken and toss. Refrigerate 30 minutes to 8 hours. USDA advises marinating poultry in the refrigerator and boiling any used marinade before serving it as a sauce.
- Heat the pan. Set a large cast iron skillet over high heat with 1 tablespoon of oil until it just starts to smoke.
- Sear the chicken. Add half the chicken in one layer. Leave it 2 to 3 minutes to char, then stir and cook until it reaches 165°F, 6 to 8 minutes total. Repeat with the rest.
- Char the vegetables. Add a little more oil and the peppers and onion. Cook 5 to 7 minutes, stirring now and then, until blistered but still crisp.
- Combine. Return the chicken, squeeze over a lime and toss.
- Serve. Bring the skillet to the table with warm tortillas and toppings.
Raw chicken can carry germs, so the CDC recommends keeping raw chicken away from other foods and washing boards and hands after slicing it.
Oven option
Roast the marinated chicken and vegetables on a large sheet pan at 425°F for 20 to 25 minutes, then broil 2 minutes. It is hands-off and good for a crowd. Find more one-pan meals in our sheet pan dinners.

Chicken fajitas on a budget
Fajitas stretch a little chicken a long way because the vegetables and tortillas fill the plate.
- Use thighs: they usually cost less than breasts and stay juicy.
- Bulk it up: add a can of black beans or extra onions and peppers.
- Make your own spice mix rather than buying seasoning packets.
- Plan leftovers: turn extra filling into quesadillas or rice bowls for lunch. Our meal prep ideas show how.
- Shop smarter: see meal planning on a budget and track pepper prices in a grocery price book.
Storing leftover fajitas
Refrigerate the cooked chicken and vegetables within 2 hours. USDA says leftovers keep 3 to 4 days in the refrigerator. Store tortillas separately. Reheat the filling in a hot skillet until steaming, about 165°F.

Frequently asked questions
What goes in a chicken fajita recipe? A chicken fajita recipe uses sliced chicken breast or thighs, bell peppers and onion, tossed in oil, lime juice, chili powder, cumin, smoked paprika, garlic powder, oregano and salt, then seared in a very hot skillet and served in warm tortillas.
How long should chicken marinate for fajitas? Marinate fajita chicken for at least 30 minutes and up to 8 hours in the refrigerator. Longer than that, the lime juice can make the surface mushy. Never marinate raw chicken on the counter.
Is chicken breast or thigh better for fajitas? Both chicken breast and chicken thigh work for fajitas. Chicken thighs stay juicier over high heat and are more forgiving, while chicken breast is leaner. Slice either one against the grain into thin strips so it cooks quickly and evenly.
How do you get restaurant-style fajitas at home? Use a cast iron skillet, get it smoking hot, cook in batches so the pan does not crowd and leave the chicken alone for 2 to 3 minutes so it chars. Cook the peppers separately so they blister instead of steaming.
What temperature should fajita chicken be cooked to? Cook fajita chicken to 165°F, the safe minimum for all poultry. Thin strips usually reach it after 6 to 8 minutes total in a hot skillet. Check the thickest piece with a food thermometer.
What are the best toppings for chicken fajitas? Classic toppings are guacamole, sour cream, pico de gallo or salsa, shredded cheese, cilantro and lime wedges. Pickled onions, sliced jalapeños, refried beans and Mexican rice round out the meal.
Can I make chicken fajitas in the oven? Yes, you can make chicken fajitas in the oven. Spread the marinated chicken and vegetables on a large sheet pan and roast at 425°F for 20 to 25 minutes until the chicken reaches 165°F. Broil for the last 2 minutes for more char.
