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!!
Why are you using flour tortillas? Corn are way better for fajitas.
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!
I wasn’t sure about baking them instead of grilling, but it was surprisingly good! Wow!
Baking really does keep the chicken juicy! Glad you liked it! 😊
Oh man, forgot to buy tortillas! Just ate the chicken veg mix. Still good.
Tasted good but way too much onion, ugh! Next time I’ll cut it down.
My chicken came out kinda dry after 25 minutes. I should’ve checked earlier, I guess. The veggies were tasty, but I had to add extra sour cream to make it less dry.
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.
Just okay. My kids didn’t eat it and that’s a big deal for me. 🤷♀️
I’m sorry to hear that! Sometimes kids can be picky. Maybe try less seasoning next time?
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?
I had to cook it for longer than 25 minutes, my chicken was still pink. Not sure what I did wrong.
I think 400°F is fine, but I would cut the chicken a little thinner. Mine came out a bit dry in spots.
Meh, my kids only want pizza. Who puts sour cream on fajitas anyways??
Easiest dinner ever! Love how colorful it looks and tastes amazing too! 🥳
This recipe was super easy and tasted amazing! My family loved it! ⭐⭐⭐⭐⭐
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!
This recipe was so easy and delicious! My whole family loved it!
I’m glad to hear that! It’s one of my favorites too. Did you add any extra toppings?
Not a fan of the tortillas… they’re too doughy for me. I used lettuce instead! 🌿
The sheet pan method is clutch. Cleanup was basically nothing and everyone grabbed tortillas right away.
Delicious! My kids loved it and I made it twice last week.
I dunno, this seems kinda basic. How can you make it fun? My kids are picky!
That’s awesome! I love that it was a hit with the kids. Can’t wait to try it myself!
I don’t think 1 pound of chicken is enough for 4 people! Need more meat.
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 didn’t have fajita seasoning so I used taco seasoning and it still tasted great. Next time I’ll add a squeeze of lime too.
So easy and honestly super flavorful. I used smoky fajita seasoning and the peppers came out perfect—tender but still a little bite. Great weeknight meal.
Fajitas are best made on the grill!!! Oven just don’t do it right!
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? 😂
I don’t know if I did something wrong, but mine turned out dry. 🙁 ⭐⭐
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!
Delicious! But I missed the guacamole part… 🙁
This recipe is amazing! So easy and delicious. My kids loved it!
Perfect for weeknight dinners! I used leftover chicken and it worked just as well.
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!
Why do you cook it on a sheet pan? Seems wasteful. 🤔
I don’t cook much, this was simple but felt fancy! 🤩
Just wow. I made this for my kids and they are devouring it. Thanks!
5 stars! Easy meal for a busy day! I added some salsa too.
I dunno, sounds kinda boring. Shouldn’t it have beans or something? Just chicken and veggies?
I totally agree! This recipe is a lifesaver when you don’t have much time. Salsa added is a great touch!
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 just didnt like it. Chicken was dry and too many veggies. Not for me.
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!
Can you use ground beef instead of chicken? I don’t eat chicken.
Yes, you can definitely use ground beef instead! Just make sure to cook it thoroughly before mixing it with the veggies.
These were amazing! So easy and flavorful. My family loved it!
What is fajita seasoning? Can I just use taco seasoning instead?
Made this tonight—so easy and the flavors are legit. The peppers and onions got perfectly tender on the edges.
