Sheet Pan Chicken Fajitas
These Whole30 Sheet Pan Chicken Fajitas are a simple and delicious meal the entire family will love. Serve in a bowl with cauliflower rice, salsa, and guacamole for Whole30, or serve in some tortillas for taco night! Gluten free, dairy free, and grain free.
I could eat mexican food every single day and it would never get old. I know it’s one type of food that I can make and it will be a hit with the kiddos, too- yay for not having to cook multiple meals for dinner! These chicken fajitas are the easiest, one-pan dish you can make. I served ours in some Siete grain free tortillas, but to make it a Whole30 compliant meal you could do these over some greens for a salad, or over cauliflower rice! You could definitely throw in some shrimp and take things to the next level!
What You Need to Make These Whole30 Sheet Pan Chicken Fajitas
You only need a few simple ingredients to make these healthier chicken fajitas.
- Avocado oil (I like to use this because of the high heat point, but regular olive oil works, too!)
- red bell pepper
- orange bell pepper
- green bell pepper
- medium onion
- 1.5 lbs chicken breasts – I love to get organic chicken breasts from Butcher Box!
- Cumin
- Chili powder
- Garlic powder
- Paprika
- Oregano
- Salt
- Black pepper
- Red pepper flakes
I love to use this 15 x 21 inch sheet pan for all of my recipes! It’s big enough so everything is spread out and not overlapping, which gets them nice and crispy!
How to make these Whole30 Sheet Pan Chicken Fajitas:
Preheat your oven to 400 degrees. Slice the peppers, onions, and chicken into thin strips (about 1/4-1/2 inch wide). Make sure the chicken pieces are of even thickness to prevent uneven cooking.
Put the peppers and chicken strips into a a large bowl and add the avocado oil and spices. Mix it all together and spread it out evenly on a parchment-lined baking sheet.
Bake for 25-30 minutes until everything is cooked through and beginning to brown. Serve the fajitas in tortillas, on top of a salad, or in a rice bowl with your favorite toppings. Enjoy!

Mary this was DELICIOUS! I am T1 and follow a low carb diet. This was so flavorful and EASY. It will be on repeat. Thank you!!
Yay! Thank you so much for letting me know – so glad you loved it!
If you add shrimp, do you cook them all together? Or do you cook the shrimp for a shorter time?
I would remove the shrimp after 10 mins so they don’t get overcooked! 🙂 Then continue cooking everything else.
Absolutely delicious, even for my Texas born husband. The chicken was tender & super flavorful. To stay whole30 we had the veggies/chicken over cauliflower rice with an avocado & salsa verde. This will be on repeat!
Woo hoo! Thanks, Ashley! So glad you both enjoyed it!
Can you share your recipe with me for the avocado & salsa verde
Hi – There is no recipe! I just add chopped avocado and salsa verde from Trader Joe’s.
Mary, this recipe is AMAZING!! My husband literally high-fived me at the dinner table! The flavor was amazing! Baking it on a sheet pan was so easy and the veggies and chicken came out perfectly. This was a huge hit with all three of my boys too! Thank you so much for this new weeknight rotation!!!
Yay!! Thanks, Julie! I’m so glad you all enjoyed it!
These are the best fajitas! Have made over a dozen times and now make the seasoning in batch and save in zip loc bags for the next time. My friend was amazed at how easy clean up was compared to her skillet fajitas.
Thank you Maggie! I love that idea for saving the seasoning!
Another awesome recipe from you. I served my over mixed organic greens, added some avocado, fresh salsa and a drizzle Tessemae’s lime cilantro ranch dressing.
I can’t wait for your cookbook to come out. Every recipe I’ve made of yours has been outstanding.
Thank you so much, Jessica! This means the world. So glad you enjoyed it!!
Loved these!! So flavorful and easy to make – cutting the chicken makes such a difference. Thank you for the wonderful recipes!
You’re so welcome! 🙂
So flavorful and easy to prepare!

Super easy and delicious!! Absolutely satisfied my craving for the local mexican joint. THANK YOU!!!
Thanks Christina! So glad to hear that!
Could I use chicken thighs for this? All we have!
Definitely!
Hands down the easiest, most delicious meal I make! I love that there is minimal clean up. It tastes delicious as leftovers too! Thank you Mary!!
Glad to hear that, Shauna! You’re so welcome!
One of our favorite easy weeknight meals – we love it with cauli rice and a bit of homemade spicy ranch or spicy mayo. Your fajitas have gotten me out of the “what the heck are we having for dinner” pickle many times!
I am so glad to hear that! Thanks Lauren!
Oh my! Mary has done it again! Made these tonight and my family has already asked to have them again!
It was so easy – and I actually prepped everything the night before and let it all marinade together in the fridge overnight and just used the sweet peppers and onions I already had on hand.
Once again this non-cook made a restaurant level meal!
These were delicious!! So tasty and the chicken came out so juicy. The flavors were perfect! I used siete tortillas to wrap them! So easy and quick cleanup!
I’m so glad you enjoyed them!
Delicious!!
These were so good! My whole family loved the fajitas! Thank you for another super yummy recipe! I served with jasmine rice, guacamole and a little shredded cheese and sour cream.
So delicious and flavorful! 10/10!
