KEY INGREDIENTS
To me, a fajita must have fresh cilantro garnish, guacamole, pico de gallo, sour cream, Oaxaca and Cotija cheeses, and lime wedges. These key ingredients are crucial for creating the best chicken fajitas tucked into a warm tortilla with your favorite fajita toppings.
- Boneless, skinless chicken breasts - buy chicken breasts, thin sliced chicken breasts, or chicken tenders. For the best results cut so that the chicken pieces are roughly the same thickness.
- Lime juice - Lime juice is the one ingredient that I won't leave out. It is the scidic tang that wakes up the entire fajita.
- Peppers and onions - A colorful assortment of green, red, orange, and yellow peppers plus red onion, white onion, or yellow onion makes these fajitas delicious and vibrant.
- Flour tortillas - Authentic fajitas always are served on flour tortillas. Use corn tortillas if you must.
SWAP IT OUT!
Versatility is a hallmark of this recipe. No green bell peppers? Any color will do. Prefer steak fajitas or shrimp fajitas? Feel free to swap the protein. For those avoiding gluten, corn tortillas can easily replace flour tortillas. Use skinless boneless chicken thighs in place of chicken breasts if you prefer dark meat.

Chicken should reach an internal temperature of 165°F to ensure it's cooked through.
TOP TIPS
- For thinner slices of chicken, slice it when it's partially frozen. Slice chicken into an even thickness for best cooking
