Easy Sheet Pan Chicken Fajitas
Roasted, perfectly seasoned chicken, colorful bell peppers, poblano peppers, and sweet onionsโall cooked together on one sheet pan. Served fajita-style with a quick, creamy Mexican-style verde sauce and fire-charred tortillas. Everything is simple, flavorful, and comes together in no time. These fajitas are a fun, any-night-of-the-week dinner that feels extra special (but is secretly so easy!).
Sure, itโs called Taco Tuesday โ but today, weโre making it Fajita Wednesday! Tacos and fajitas are kind of like cousins. Traditionally, fajitas are served sizzling hot on a skillet with grilled meat, peppers, and onions. Tacos are more grab-and-go, often with a wide range of fillings.
Honestly, maybe these are a little taco-ish. But my vision was fajitasโand Iโm sticking with it. These are fresh, flavorful, and so perfect for summer nights.
I actually made this recipe a few weeks ago, just before Cinco de Mayo, but waited to share it because it felt a little more seasonalโbright and summery. Iโve been saving it for the right Tuesday!
And according to my cousin Abby, today is that day. Sheโs been asking for the recipe since she first saw the preview and said, โYou need to post it already!โ
So here it is! Iโm really excited to finally share these. Theyโre simple to prep, especially when you use my homemade Mexican fajita/taco seasoning blend. Honestly, the most time-consuming part is just slicing the veggies!
Letโs jump into the details
Ingredients
- chicken breast
- salted butter โ or olive oil, but I prefer butter
- garlic
- taco seasoning โ I shared my mix in the notes
- yellow onions
- bell peppers
- poblano peppers
- flour tortillas โ I love Caramelo Tortillas, charred them over a gas burner
- mashed avocados and lime โ for serving
Ingredients โ for the sauce
- plain Greek yogurt
- mayo โ or you can use more Greek yogurt
- salsa verde
- pickled jalapeรฑos
- cilantro
- Cotija or feta cheese
Special Tools
For these quick fajitas, you need a sheet pan and a mixing bowl. Plus a few other everyday kitchen tools.
Steps
Step 1: Roast the Chicken, Peppers & Onions
On a large sheet pan, toss the chicken with a few pats of butter, minced garlic, your favorite taco seasoning, sliced onions, bell peppers, and poblano peppers. Season everything generously with salt and pepper.
Spread everything out in an even layer and bake until the chicken is cooked through and the veggies are tender. The exact time will depend on how large or small you slice the chickenโjust keep an eye on it!
Tip: If your sheet pan feels crowded (or youโre doubling the recipe), divide everything between two pans for even cooking. Itโs perfect for meal prep too!
Step 2: Mix the Creamy Verde Sauce
While the chicken is roasting, whisk together the quick creamy verde sauce. Itโs super simple but adds so much flavor.
In a small bowl, combine:
-
Greek yogurt
-
Mayo
-
Salsa verde
-
A few pickled jalapeรฑos for heat
-
Fresh chopped cilantro for brightness
Stir it all together and set aside. Thatโs it!
Step 3: Assemble the Fajitas
Now for the fun partโbuilding your fajitas!
I love to char flour tortillas over the gas burner for a little smoky flavor. If thatโs not an option, just warm them in a dry skillet until theyโre lightly toasted.
Hereโs how I like to layer mine:
-
Start with smashed avocado, seasoned with lime juice and flaky sea salt.
-
Add the roasted peppers and onions.
-
Top with juicy, golden chicken.
-
Drizzle over that creamy verde sauce.
-
Finish with shredded cheese, fresh cilantro, and a good squeeze of lime.
So delicious. So easy. And such a fun dinner any night of the week!
The sides
When it comes to fajitas, the sides are just as important as the main event! I love serving these with a side of rice and homemade tortillas chips. I bake the chips in the oven using tortillas, olive oil, and sea salt. We love them!
Donโt forget the essentials:
-
Smashed avocado or guacamole
-
Fresh lime wedges for squeezing over everything
And of course, a margarita (or two!) makes it all feel like a summer celebration.

These looked delicious but turned out even better than expected. They were so easy to put together and really delivered on flavour. This instantly became a family favourite and they will be made again!
Hey Kristina,

Delicious! The whole family loves this recipe! Going into the rotation. And, on the list for when we host family and friends. Thanks for another great recipe, Thieghan!
Hey there,
Thanks a bunch for making this recipe and your comment, so glad to hear it turned out well for you!
Have a great week!
I followed the recipe as written and it is quick and easy and my family agrees it is great! My husband actually said to add this to my list of make again recipes.
Hey Lyla,
Fantastic! Love to hear this recipe turned out nicely for you, thanks so much for making it!
Have a wonderful week!
The sauce was soooo good (even though I had to have the cilantro on the side because the husband thinks it tastes like soap ๐)! Great way to elevate my normal fajita topping of Greek yogurt and salsa. Loved it!
Thanks so much, Kristy! Love to hear this!
Your Cotija Sauce is confusing – I added the 1/2 cup of cheese to the sauce. After reading the top, which I rarely do, it omits the cheese when making the sauce. And the recipe for the sauce says: To make the sauce, combine all ingredients in a bowl. Season with salt.
So, how do you make it?
Hi Jane,
You can follow the recipe as written by adding the 1/2 cup of cheese to the sauce:) I hope you love this recipe!
This was so delicious! Loved everything about it and so did the family!
Hey Cindy,
Awesome! Love to hear this recipe was enjoyed by your family, thanks so much for making it!
These were really tasty. I would suggest making at least half if not less of the sauce though. It was waaaaaay too much for this amount of fajitas. It was good though (although I am such a wimp with spice that I would put less salsa verde in it next time- ha!) and I put the rest in the freezer to eat this recipe again in the future.
Hey Aubree,
Your feedback means a lotโthanks for trying this recipe! I’m happy it delivered!
We make fajita bowls every week for one our meal preps but I was so tired, it was cold outside, and did not want to grill this time. Though this didnโt give it the char we love, the flavors were very yummy and the meat was so tender! We used chicken thighs because theyโre cheaper for the amount you get! I didnโt have poblano or all of the ingredients to make the crema, so Iโm excited to try this again but with the crema next time. Sounds amazing. I will also add more salt next time!
Hey Jenny,
Happy Monday! I appreciate you giving this recipe a try, so glad to hear it was a hit!
I have made this recipe for parties with young and old and everyone loves it and says you can smell it outside walking up to the house and it smells so good. Itโs pretty easy and delicious!
Thanks so much, Ann! Love to hear this recipe turned out well for you, I appreciate you making it! Have a great Monday!
This was so good and SO easy. Perfect weeknight dinner. The sauce makes it. I put a lot of pickled jalapeรฑos in it – and it was spicy! Charing the tortillas really makes it! I will put this in regular rotation.
Hey Mary Beth,
Thank you so much for giving this recipe a try and sharing your thoughts, so happy it worked for you!
My favorite!!! On repeat every week for months now and tonight making it for guests too!
Yay! Thanks so much, Cristina! Love to hear your family has been enjoying this recipe! Have a great weekend!
I have made fajitas many times, but these were fantastic! Loved the added Poblano Pepper to the mix of veggies for added spice and the Cojita Verde Sauce is amazing (even though I had to leave out the pickled jalapeรฑo – couldnโt find them at my grocery store).
Yum – thank you!
Thank you so much Julie! So so glad you loved these fajitas! xT
