These easy, flavorful, sheet pan chicken fajitas are sure to become a favorite! They’re oven-roasted to perfection!

I love a quick and simple dinner. These sheet pan fajitas are just that! They only take a few minutes to prep and the rest is done in the oven. Meanwhile, you can whip up some of our favorite spanish rice and a bowl of homemade guacamole!

Easy Sheet Pan Fajitas

We’ve made these fajitas at least 7 times over the past few months. I think it’s safe to say they’re a favorite.

Not going to lie – They take a little extra prep work (meaning you’ve gotta slice up peppers, onions, and chicken) but other than that, they’re a breeze!

A few things I love about these sheet pan fajitas is everything is cooked on the same sheet pan so all the flavors blend together. It is pretty healthy with all the veggies and protein. You don’t have to babysit it at the stove. And you have fewer dishes to do after dinner!!

How to Make Chicken Fajitas

MARINATE. You can marinate the chicken overnight in a liquid marinade but I prefer to use a dry rub because I usually forget to marinate my chicken in advance, plus dry rubs work better than liquid marinades! We want the moisture from the chicken to evaporate quickly so it will sear well and create a delicious caramelized crust.

PREP. While doing all your prep work, preheat your oven to 400 degrees and place your baking sheet in the oven so it is nice and hot! Begin by chopping the bell peppers, onions and chicken. For cutting raw chicken, use a sharp knife that is not serrated. Make a clean cut rather than a sawing motion.With peppers and onions, cut them in long strips.

ROAST. Place your bell peppers and onions on the sheet pan. Spread them out evenly across the pan and roast them for 8 minutes. (Tip: Warming the pan before adding the veggies gives you less of a risk that the veggies stick and burn on the pan.)

While the veggies are roasting, mix the chicken and seasonings (dry rub). You can use the store-bought version if you are looking for a short cut!  

Add the chicken to the pan (making sure to separate the pieces of chicken so they don’t stick together) and bake for another 15-20 minutes or until the veggies are roasted and the fajitas are golden brown! 

After it comes out of the oven squeeze some lime juice over top (add a touch of freshly chopped cilantro) and it’s ready to be devoured- and trust me it will!

SERVE. I like to put my fajitas in a flour tortilla, but you can use corn or omit the tortilla altogether if you are trying to eat keto/low carb! Then I like to top it with cheese, sour cream, salsa and lettuce

Recipe FAQs

How to control the spice level? If you are concerned about the spice level you can decrease the amount of chili powder and chili flakes. This might be something to consider if you’re making it for kiddos.

Can you put whole pieces of chicken on the pan? If you choose to not cut the raw chicken just make sure to cook until the chicken is cooked through. Use a meat thermometer to ensure that it reaches 165 degrees.

Crockpot Instructions: Cover the bottom of the pot with a can of diced tomatoes and then the boneless chicken breasts and then the sliced veggies. Cook on high for 2.5-3 hours or on low for 4-6 hours then you can cut or shred the chicken. Just cook until the chicken is done and the veggies are tender. This is a great option but you will miss out on the caramelized texture of the chicken and roasted flavor of the veggies!

Instant Pot Instructions: Toss the chicken in the dry rub and then place the chicken strips on the stainless steel insert in the instant pot with a little oil on the bottom. Top with sliced peppers and add a ½ cup of water. Then set to manual high pressure for 10 minutes and after that quick release the pressure.

How to Store + Make Ahead

Sheet pan chicken fajitas are definitely best fresh, but you can do some of the prep work ahead of time! You can chop the veggies and chicken, the night before or the morning of, and store them in separate containers in the fridge. Or you can even chop them and freeze them for a future meal, just thaw it in the fridge the night before!

If you have leftovers, store them in an airtight container in the refrigerator for up to 4 days. Reheat either in the microwave or in a pan on the stovetop!  

Just know that these are gonna be good and you will soon find this recipe on repeat! Enjoy!!

Notes

*I prefer cutting the chicken against the grain. I find that this method creates more tender strips of fajita meat.
**Do NOT use olive oil!! We are roasting at a very high temperature. Olive oil should not be used at 400 degrees. I've used all three types of oil, however, vegetable and avocado are my favorite.

  1. I made these today and they were awesome. One pan was chicken and one pan was steak…the chicken one was definitely the best. The chicken was tender. I also thinly sliced a jalapeno and added it to the onion and peppers. I will definitely make this again!

  2. LOVE this recipe!! I’m a foodie and look at lots of recipes…this one was easy and exactly what I was looking for. Seasoning from the chicken flavors the pepper and onions perfectly. I’ve made it twice in two weeks!! Once with flour tortillas and once with corn tortillas, both delicious. I will make two pans and pop it all in a crock pot and serve it at our Christmas party this year. I know it will be a huge hit! Thanks so much for the recipe.

      1. 5 stars
        My family loved these fajitas. They are so flavorful. I like it because you don’t need to serve anything else with it.

  3. This is by far the best (and easiest) recipe I have tried for sheet pan fajitas. Low cal – even my daughter who watches everything she eats- loved it.. It also satisfied the big eaters in my family. Spices were delicious.. I did not feel the need to add oil to the chicken, I just laid the chicken coated with the spices  on top of the peppers and onions which I did put in the oven ahead of time.. I did preheat the baking sheet as suggested while I attended to the pepper and onion prep. Thank you.. This will become a go to recipe. 

  4. This recipe was delicious and quick to make! For my family, the amount of spice was perfect, the chicken was tender, the peppers and onions were awesome, not soggy. My family really enjoyed this dish, they said it was like they ordered from a restaurant, it was so good!

  5. Great chicken recipe for a quick dinner. I really love spicy food and chicken so I might try this tonight.

  6. Perfect recipe. I don’t say that very often, but this is wonderful. If I would tweek anything, I would used a little better chicken than the thigh. Never cooked with thigh of a chicken and it was a little more gristle/fat than I am used to. But then again, maybe that is why the chicken was so juicy and good. Jury out.

  7. I’m getting ready to make this for tomorrow’s late lunch/early dinner. Very excited to make it!! QUESTION:
    Can I assemble the chicken/spicemixture the night before? 

  8. While the spices could be tasted, the chicken itself did not have any flavor. Would marinating it overnight help?

  9. This popped up on my FB today which was serendipitous since I was just looking for chicken breast and bell pepper recipes. I couldn’t find anything that seemed like a quick prep for weeknight dinner. My hopes weren’t high because I didn’t think the chicken would be moist.  I am so happy with this recipe! It was easy, the tip regarding cutting the chicken was spot on.   I wish I would have made more! This is a great base recipe that I bet could be altered for different flavors and. Ombinations. Thank you for this winner! 

    1. Hi Amy, I haven’t made these with thighs before. I would definitely suggest using breasts over thighs because breasts are leaner and get a nice crisp exterior as they roast. Thighs will produce too much liquid on the sheet for things to get properly cooked.

  10. Amazing! I added asparagus to the onions and bell peppers, cause I live asparagus! So good. Such tender chicken! Thank you!

  11. Any way I can make ahead and freeze for a party coming up? Cook as usual and beat up in crockpot?

  12. So good. I prepped ahead of time and prepared these for my AHG troop. Rave reviews from the girls and everyone ate it. Co leader wants that recipe.  

  13. This was so delicious. I made it as written with no substitutions. I don’t think I’ll ever try another fajita recipe.  

  14. This is the second time I have used this recipe and will certainly be using it again. Absolutely delicious!  I cook the vegetables for longer than the recipe suggests but that is down to personal taste.
    I serve it with avocado, sour cream and grated cheese and plenty of lime juice.

  15. Excellent fajitas!  Loved that it is done in one pan.  Lined the pan with foil for easy clean up.  Just add chopped cilantro as a garnish.  This recipe is a keeper!!

  16. This is a great recipe! I did add more cayenne to the seasoning mix because my husband and I like spicy. I’ll probably add a jalepeno or two next time, but overall absolutely delicious! 

  17. My family LOVED this recipe!
    I changed it slightly, however. Instead of using bell peppers, I used Anaheim and jalapeno peppers, cut and baked the same way.

  18. Great recipe! Cooking times, including preheating the pan, and seasoning amounts were spot on (unless you want it spicier). All the kids and adults loved this. Easy to scale up and great for a party with homemade guac.

  19. Man I wish you had that comment about it using olive oil in the actual recipe where it instructs to toss the veggies. I didn’t read to the end and used olive oil. 🤦🏼‍♀️ Lol!!

  22. 5 stars
    This was really easy and so very good!! Don’t know why but it would not let me give it five stars. 

  23. I love that these are made on one sheet! Less dishes are the best. This meal was a hit with the entire family too. So flavorful and filling.

  24. 5 stars
    This is one of my go-to recipes, and it’s a favorite of my two young kids and husband! The flavor is excellent and sheet pan fajitas are so much better (and easier!) than grilled. I am kind of a flavor snob. If I’m going to eat, I want it to taste great, even if I’m just eating a burger, and this flavor is a home run! Thank you for the recipe!

  25. 5 stars
    Planned to take pics when the pan came out of the oven, but my family dug in! Really good recipe. The prep work with slicing everything is not so bad once you get to walk away from the stove while it all roasts. Delish!

  26. Love this recipe. I can’t tell you how many times I have made it. My husband requests this meal almost every week! It is so good for Taco Tuesdays. The chicken is always tender and flavorful and the combination with the onions and peppers is perfect. We make a side of cilantro lime cauliflower rice to keep it a low carb meal. Thank you for this recipe!

    1. You are so welcome! The cilantro lime cauliflower rice sounds like a prefect side for these fajitas. Thanks for sharing!

  27. 5 stars
    Just made this for dinner, it is the best fajita recipe ever! Will definitely make this again and again. Thank you for sharing. I used chicken tenders instead of breast, turned out great.

    1. Thank you! I’m glad you enjoyed the fajitas! The tenders sound like a great substitution too.

  28. 5 stars
    My family loved these fajitas. They are so flavorful. I like it because you don’t need to serve anything else with it.

    1. Yay! I’m glad your family enjoyed the fajitas. And yes, they have it all in that one pan. So quick and easy!

  29. 5 stars
    Made this on the bbq because it was too hot to turn on the oven. I will definitely be making this again and again. I think this would be delicious over rice.

    1. Ooh I bet it was great over the bbq too! And I have had it over rice… very tasty too. Glad you enjoyed the fajitas!
