Sheet Pan Fajitas are SUCH an easy meal for the whole family!
Easy.  Healthy.  Versatile. Sold! Tender fajitas with chicken, fresh veggies, all cooked up on the same sheet pan! Serve with tortillas, on top of a salad or wrapped up in a lettuce wrap.
Check out this video to see how easy these Sheet Pan Fajitas are to make!   Toss it together then throw it in the oven and boom….dinner done!  I love the concept so much, I am busy developing several more sheet pan recipes to share with you soon.  Been up to my elbows in sheet… pans that is..argh, somebody stop me.
HOW TO MAKE CHICKEN FAJITAS!
- Slice your veggies and chicken. Â Keep them the same size so they cook at the same time.
- We used a variety of colored peppers. We sometimes throw in a sliced poblano for a little extra zing!
- Mix spices and olive oil for a delicious and healthy homemade fajita marinade.
- Toss chickens and vegetables in marinade on sheet pan.
- Bake until fully cooked and enjoy!
We love this set of three sheet pans, a size for everything. After adding everything to your sheet pan, measure out all your spices and toss right into the olive oil.
Cumin, chili powder, garlic, salt and pepper into some olive oil makes your perfect fajita marinade. Â The olive oil and the spices really help put some flavor into the fajitas- this easy spice mix works great even if you were to marinate the chicken and just bake chicken breasts by themselves.
We find this homemade version to be so much more flavorful AND healthier than packaged/store bought fajita or taco spices. Be cautious if you plan on using it for grilling though- olive oil plus an open flame can be a dangerous, very flammable thing.
Kick it up with hot sauce, or maybe a jalapeño mixed in with the veggies if you like spicy.  Serve with sour cream, avocado, grated cheese…all your favorite fajita fixings!  Wrap it all up in a warm tortilla, lettuce leaf or dump it on salad!  We love the flavor of this chilled, too. Another few reasons to love this recipe. It’s healthy, low fat, low carb, Paleo and Whole30 compliant.  It also feeds a crowd and provides leftovers for that boring old lunchbox.
Learn more about how to make Sheet Pan Fajitas with Chicken:
- Chicken is fully cooked at an internal temperature of 165 degrees farenheit. We recommend using a meat thermometer.
- Toss the fajitas midway through cooking to make sure everything is cooked evenly throughout, but also to double coat the fajita seasoning on the chicken and vegetables.
- Slice your chicken and veggies about the same thickness to ensure everything is done at the same time.
- Use the convection feature on your oven if you have it, it will brown the veggies nicely.
- You can substitute a casserole dish or 9 x 13 cake pan in a pinch.
- Top yours with avocado, cilantro and red onion (like below) and toss around to warm those up- adds a ton of flavor without a ton of calories.
- You do not have to line the sheet pan with foil as the olive oil will help slide the fajitas right off; but we find the foil makes for easier clean up and recommend it.
- If you want to reheat these, simply pop them in the microwave on medium heat for 30-45 seconds. You can also reheat them in a stove top skillet until warm throughout- this will help keep the chicken tender and will yield slightly better results than microwaving.

This is a fantastic recipe! I’m on day 7 of a whole 30 and spent hours in the kitchen yesterday and needed today to be simple and delicious. This recipe delivered! Thank you!
Thank you Danielle!
Hello Kathi, just found this recipe. I love sheet pan recipes and slow cooker recipes, I work late most nights and when I get home it`s hard getting supper done before it`s time to put little ones to bed. Getting everything ready before work and then popping it in the oven when I get home or having hubby watch it in the slow cooker is great. I would love to do this recipe, but everyone is getting a little tired of chicken, could I use maybe a flank steak or some other kind of beef? Thank you in advance, and have downloaded all of these 6 pan pan sheet dinners. Going to try the salmon fajitas next sunday.
Hi Pauline! I think you could use most any protein with it as long as it’s cut thinly enough to get done at the same time the veggies are done! Don’t blame your family for getting tired of chicken, I think we are gonna start to cluck around here soon! Maybe a dark meat chicken thigh?
Can I do this without slicing the chicken?
Sure! Just make sure your onions and peppers are cut in thick strips so they don’t over cook while the chicken cooks!
Wondering if I can mix and coat the chicken/veggies in advance and then freeze them to be pulled out a few days later?
Hi Michelle – gosh, I don’t think I could recommend it, I haven’t tried it! I’m not sure how the olive oil will freeze. Sorry, not much help :(.
I loooove this recipe! I have made it several times for my family and we enjoy it every single time. Just made it for a friend who just had twins and she said it was absolutely delicious…..two thumbs up for sure????
Made this for dinner last night… It was a huge hit!!! So easy to make. I had to double it because I had to use the chicken I had. So so so good!! Thank you!!
I love leftover fajitas for lunch! So glad you liked it!
Such a flavorful simple recipe! My new go to recipe!
Making this now 😉 if using convection feature on oven do I still set temp to 400 ?
Sorry I couldn’t respond in time! Yes, still use 400. I use my convection feature for this recipe as well. It helps brown the veggies. Thanks!
I made this recipie for sheet pan fajitas for dinner tonight. This recipie was wonderful.
It was easy to follow and the chicken and peppers and onions,cooked well and I will
Definately be making this recipie again.
Thank you
Hi Susan, I’m so glad you liked them! Truly appreciate you taking the time to send a note!
I ran across this recipe, and your blog, last Friday. I made this over the weekend and my son loved it. He said there was just the right amount of spice and thought the flavor was terrific! For easy clean up I lined the pan with aluminum foil. Perfect! Thanks for a great recipe. Will definitely make it again.
So glad! Thank you so much for taking the time to send a note!
Delish. Made this for hubby & kids. Everyone loved it!!
These are my favorite kind of notes! So glad your family loved it. Thanks for taking the time to write!
Just made these for dinner tonight. They were amazing! Definitely a keeper recipe I’ll make often!
Hi Kat! I’m so glad you liked them I just made a whole sheet of them on Sunday for my Whole30! Thanks for the comment!
Did you serve anything else with them (I’m planning avocado)? I’m making these tonight for Whole30 day 4 🙂
Be aware: tortillas, sour cream, and cheese add-ins are not on the Whole 30 plan.
I think everyone on the plan understands the extra add-ins are not Whole30 compliant but thanks for the warning.
I can’t wait to make this fajita recipe. I’m going to double it since I like to cook in batches. However I’m concerned about you saying to use tortillas and add sour cream and shredded cheese since none of those are Whole 30 compliant. Your recipe is on the Whole 30 set of recipes you’ve gathered, but then you add none compliant ingredients. That being said, I still can’t wait to make the fajita part. I’ll eat it as is and also in lettuce or Napa cabbage wraps, over a sweet potato and with scrambled eggs. I know it’s going to be yummy.
