Sheet Pan Chicken Fajitas are an easy, one-pan meal that combines tender chicken, vibrant bell peppers, onions, and zesty fajita seasoning – all roasted together for a flavorful, no-fuss dinner. This dish is perfect for busy weeknights when you want a healthy and satisfying meal with minimal cleanup. The ingredients are simple, but the flavors are bold, with the chicken and vegetables infused with smoky spices and a touch of citrus.
To make Sheet Pan Chicken Fajitas, start by slicing chicken breasts or thighs into strips and seasoning them with a blend of chili powder, cumin, paprika, garlic powder, onion powder, salt, and a squeeze of lime juice. Bell peppers and onions are also sliced into strips and tossed with the same fajita seasoning to ensure every bite is bursting with flavor.
Everything is arranged on a sheet pan and roasted in the oven until the chicken is perfectly cooked and the vegetables are tender and caramelized. The result is a sheet pan full of smoky, savory chicken and crisp, sweet peppers and onions. The roasted vegetables are slightly charred around the edges, giving the dish extra depth and richness.
Once everything is cooked, serve the fajitas in soft flour tortillas or warm corn tortillas. Top them with your favorite toppings, such as sour cream, guacamole, salsa, shredded cheese, or cilantro, to make them even more delicious.
Sheet Pan Chicken Fajitas are not only easy to make, but they’re also highly customizable. You can swap the chicken for shrimp, beef, or a vegetarian option like tofu or beans. Add other vegetables like zucchini or corn for added variety. You can even adjust the level of spice by using more or less chili powder or adding jalapeños.
This dish is great for meal prepping, as the ingredients can be prepped ahead of time and roasted just before serving. It’s perfect for a casual dinner with family or friends or even a taco night. The best part? Cleanup is a breeze, with just one pan to wash!

Why do people keep adding sour cream and guac? The fajitas are good enough without it!!
5 stars! Made it twice this week! So quick!
I don’t know… Seems like too much oil to me? Can it be done with less? 🤔
I agree! This recipe is super easy and delicious! I’ve made it for my family too, and they loved it! 😊
Fajitas on a sheet pan? Genius! I usually stand over the stove. Will do this every time now 🥳
This is such a great idea! I hate cleaning pots and pans! Can’t wait to try it! 😍
Yeah, but isn’t it the same as normal fajitas? Not sure it will taste as good…
What are ‘fajitas’? I just put chicken and veggies on bread.
Soo good! The seasoning hit just right! Also, I forgot the tortillas, so I just ate it with chips. Yum!
Glad to hear you enjoyed it! Using chips sounds like a fun twist!
Oh man, forgot to buy tortillas! Just ate the chicken veg mix. Still good.
This is lit! I added some jalapeños for a kick! 🔥
This is basically just chicken and stuff. Kinda overrated? Making fajitas in a pan seems lazy.
My tortillas burned in the oven. Maybe I’m not doing it right?
Don’t worry! It happens. Maybe try lowering the oven temp a bit next time?
Easiest dinner ever! Love how colorful it looks and tastes amazing too! 🥳
What do you mean by fajita seasoning? Is that like a spice or something? 🤔
Yum! But I forgot to preheat the oven and had to wait longer. Still worth it!
I always forget to preheat too! But hey, better late than never! Glad it still turned out yummy!
I don’t know, it seems too simple. I expected more flavors or something special. Might need to add more spices next time.
But the simplicity is what makes it easy! Sometimes less is more, you know? Just try adding some hot sauce.
I think it’s all about the toppings! You can make it special with some fresh lime and pico de gallo. Give it another try!
Not a fan of the tortillas… they’re too doughy for me. I used lettuce instead! 🌿
Amaze recipe! I added some corn and it worked! Yum!
That sounds delicious! Corn must add a nice sweetness. I’m trying that next time!
Did you really need that much olive oil? Seemed kinda greasy to me. I just used a bit.
Quick and yummy! I used leftover turkey instead of chicken and it still turned out great. 10/10 would recommend.
Wow, this was so easy and super delicious! Whole family loved it! 🌟
But is it really that good? I mean, just throwing stuff on a pan and baking? 🤔
I’m so glad your family enjoyed it! It’s one of our favorites too! 🌈
I don’t understand how it’s graded easy. The chicken got burnt in the oven. What did I do wrong? 😩
Maybe you left it in too long or your oven runs hot? I set mine at 375°F and it turns out good. Don’t lose hope!
I don’t like chicken. Can I use beef instead? 😂
This is the best chicken fajita recipe I’ve ever tried! My family loved it and it was super easy to make. Will definitely make again!
These were a hit with my family! So easy and delicious!
Hit? More like a miss for me. The chicken was kinda dry and the seasoning was not enough. 🙁
I’m glad your family loved it! It’s one of my favorites too. So easy to make on a busy night!
This recipe is amazing! So easy and delicious. My kids loved it!
This recipe was super easy and delicious! My kids loved it!
My chicken took a lot longer to cook. It’s kinda dry now. 🤷♂️
Maybe try checking the chicken’s internal temp next time? It should be 165°F. That might help! 😄
I swapped chicken for tofu and it was still delicious! I’m a vegetarian and this recipe worked great for me!
Fajitas are always a good idea! 👍 Can’t go wrong with them!
I don’t cook much, this was simple but felt fancy! 🤩
It turned out okay, but I think I missed something. The seasoning didn’t really stand out.
Maybe you didn’t use enough seasoning? It’s important to coat everything well. I usually add extra just to be safe!
I tried it but the chicken was kinda dry. Maybe bake it less? Had to drown it in salsa to eat it.
I had some problems, the chicken was dry. Maybe less time?
Easy to make and clean up! 🥳
Absolutely love how quick this recipe is! Perfect for busy nights. 🌟
Too spicy for my liking. Shouldn’t be called fajitas!
100% making this again! So good and healthy too.
Total disaster. Burnt the chicken to a crisp! 😢
Oh no! That sucks! Make sure to keep an eye on it next time. 😬
I dunno, these ‘fajitas’ were just stir-fry in a tortilla. Not impressed.
Yummy! My kids loved it—definitely making again! 😍
So much flavor! I did it all in one pan, very handy for cleanup.
Simple but tasty! I can see myself making this again for sure.
Not sure I trust this one tho. Fajitas need grilling, right? This baking seems weird.
Nah man, fajitas are grilled, like you said. This ain’t it!
I totally get your skepticism! But baking can actually keep the chicken juicy too. Give it a shot, you might be surprised!
It was ok, but I think the seasoning could use more flavor. Did I mess up?
I tried this but it came out kinda bland. I think more spices would help.
I added some extra garlic and lime juice. Yum!
Wow, this is so good! Tasted just like the fajitas from my fave restaurant.
