These sheet pan chicken fajitas are the easiest weeknight dinner you will ever make, with juicy seasoned chicken, colorful bell peppers, and sweet onion all roasted together on one pan for minimal cleanup. These easy chicken fajitas are an easy, healthy, and flavorful weeknight dinner served with all your favorite toppings.
Preheat oven to 425°F. Put a large sheet pan in the oven while it preheats. A hot pan helps the chicken and vegetables sear instead of steam.
Marinate chicken. In a large bowl, mix olive oil, lime juice, and all seasonings. Add sliced chicken. I suggest marinating for at least 30 minutes.
Spread on the hot pan. Carefully remove the hot sheet pan and spread everything in a single layer. Don’t crowd it too much. Use 2 pans if needed. Sprinkle peppers with salt.
Bake for 18–22 minutes, tossing once halfway through, until the chicken is cooked through and the vegetables are tender.
Broil for flavor.Broil for 2–4 minutes at the end to get some browned edges. Watch closely.
Finish with fresh lime. Squeeze more lime over everything and sprinkle with cilantro. Serve with guacamole or avocado, sour cream or mexican crema, fresh lime wedges, salsa or pico de gallo, shredded cheese, and warm tortillas
Notes
Storage: Store leftover chicken fajitas in an airtight container in the refrigerator for up to 4 days. Keep the toppings separate so the tortillas and toppings stay fresh.
