How To Make Sheet Pan Chicken Fajitas

Preheat the oven to 425. Lightly oil the pan with cooking oil.
Slice chicken breast pieces, bell pepper and onion into ¼ inch strips. Slice so the meat and vegetables are about the same size so everything cooks evenly. Some thicker chicken breasts may need to be sliced in half as well as into slices to get strips that are roughly ¼ inch thick. Add the chicken and vegetables to the sheet pan in an even layer.

In a small bowl mix together olive oil, oregano, cumin, garlic powder, paprika, cayenne pepper and salt. Pour the mixture over the sliced chicken, peppers and red onions.

Place the sheet pan in the oven for 25-30 minutes or until the chicken is cooked all the way through. You can check the chicken with a meat thermometer that it has reached 165 in the center. Serve with warm soft tortillas and enjoy! You can also squeeze additional fresh lime juice over top of the fajitas at the table if desired.

Variation Ideas

Add zucchini- thin-sliced zucchini or yellow squash can be delicious to add to the fajita veggies
Swap or add mushrooms- Sliced fresh mushrooms, especially portabella mushrooms, are really delicious added to this recipe. You could also swap mushrooms for the chicken to make a vegetarian version of these fajitas.
Add poblano peppers- These delicious peppers are mildly spicy (less spicy than jalapenos) and you prep them the same as bell peppers. Remove the seeds and stem, then slice. I recommend adding one or two peppers the first time.
Try shrimp – Shrimp can be delicious in this dish and is an easy swap! I’d plan for between a pound and a half of shrimp and two pounds of shrimp and make sure to devine the shrimp first. Expect shrimp may cook a little quicker, I’d start checking it after 15 minutes for doneness. I also recommend cutting the vegetables extra thin so they cook at the same rate as the shrimp.
Swap taco or fajita seasoning – While I love the spice blend on this dish, you can swap a more basic taco seasoning or Mexican-inspired spice mix blend. I recommend using 4 teaspoons of seasoning and still adding the teaspoon of salt. If your premixed seasoning is especially salty, decrease the salt to 1/2 a teaspoon or the salt can be omitted if you choose.
Add hot sauce- A drizzle of hot sauce gives these sheet pan fajitas a spicy kick at the table, yum! Use a little or a lot of hot sauce to your own taste.

What To Serve with Chicken Fajitas

There are so many delicious and easy options to serve with chicken fajitas! Pick a topping or two, or add a bunch of toppings to round out your meal.

Blender Salsa – This is a more tomato-based restaurant-style salsa, perfect for tacos and chips!
Cheese – shredded Cheddar, crumbled Queso Fresco, or shredded Monterey Jack cheese are all great choices for tacos.
Guacamole – Fresh homemade guacamole is SO good and a super quick recipe to make. Great for chips or tacos!
Sour Cream – or creme fraiche is delicious too!
Pico de Gallo – mild chunky salsa, this is what is included in the pictures
Black Bean Corn Salsa – Serve hot or cold!
Cilantro – A little fresh chopped cilantro adds so much freshness to tacos, but if you don’t like cilantro you can also try fresh parsley.
Street corn dip – this delicious dip is as yummy on top of tacos as it is on a chip!
Shredded Cabbage or Lettuce – Chop or shred cabbage or lettuce for extra crunch!
Spanish Style Rice or Cilantro Lime Rice – makes a quick and easy side! Spanish-style rice is often found at a Mexican restaurant while cilantro lime rice is a copycat from Chipotle.

How Long Do Chicken Fajitas Last?

Expect these chicken fajitas will last for three days when stored in an airtight container in the refrigerator.

Can I prep these Chicken Fajitas Ahead Of Time?

You could prep this pan ahead of time by slicing the vegetables and the chicken, and then add the other ingredients right before cooking.

You can also even marinate the chicken and the vegetables in the oil and spices ahead of time. If you choose to marinade for more flavor, I recommend marinating for 4-5 hours for the ideal flavor.

I wouldn’t marinate for longer than 24 hours though because this recipe has lime juice in it. The lime juice can begin to change the texture of the chicken and it won’t taste it’s best if marinated for more than 24 hours.
