Vegetables + Seasoning Used for Whole30 + Keto Sheet Pan Fajitas
To keep these authentic mexican restaurant style, I like using bell peppers and red onions. Both are whole30 + keto friendly! But I’ve swapped in other vegetables I have in the fridge too, like zucchini, squash, broccoli, tomatoes, cauliflower, etc.
I coat the vegetables and chicken in olive oil to add some healthy fat, then season them all in my homemade taco seasoning. So much better and healthier than store bought, which usually has preservatives and sugar.
Secret to Juicy Chicken in Sheet Pan Fajitas
A lot of sheet pan chicken fajita recipes I’ve tried have you pre-cut the chicken breasts into strips, and throw it all on the baking sheet. When I’ve made them this way, the chicken gets so dry and overcooked, since it cooks way faster than the vegetables.
The secret to juicy chicken is to leave the chicken breasts whole! This way they will cook at the same rate, but the chicken will still be juicy. After it is done roasting slice and serve!
I like using medium size 6-ounce chicken breasts. If you’re using those great big huge chicken breasts, give them a slice horizontally to make them thinner.
Serving Suggestions for Whole30 + Keto Sheet Pan Chicken Fajitas
My favorite healthy way to enjoy these chicken fajitas is in a loaded up burrito bowl, or taco bowl. I’ll fill it up with cauliflower rice, sliced lettuce, guacamole, salsa and some jalapenos. Some cashew queso would be amazing too!
You could also mound it on top of a bunch of chopped lettuce as a fajita salad, use butter lettuce to make a healthy taco, or of course regular ‘ole tortillas if that works with your diet.
Whole30 + Keto Sheet Pan Chicken Fajitas Meal Prep
This makes an amazing meal prep too! Especially since the oven does most of the work for you, so you’re not spending your Sunday cooking away.
Once the fajitas have cooked and completely cooled, I’ll put them in a meal prep container with my favorite toppings to make a burrito bowl. When it’s lunch time, I enjoy it cold, but I included instructions to heat it up if you like it warm.

Just made this for dinner. The family loved it! Our meal plan this week was the verde chicken, sheet pan fajitas and the 5 ingredient Shawarma meal. They’re all easy and amazing! Thanks Natalie!
This one quickly became a family favorite!
It is fantastic that my sheet pan fajitas are a family favorite Tara. They are my family’s favorite too!
Our favorite of the sheet pan recipes but make sure you include the queso…. it is beyond worth it! This has become a family staple for us… highly recommend!
I love that you pair the sheet pan fajitas with queso Marissa. Oh my that sounds delicious!
So yummy! Making this tonight for the second time in two weeks. Loved by my whole family including 2 teenage sons. Also made for great leftovers for my lunch the next day.
I love that you have made them twice in 2 weeks Rebecca. They must be a hit! So glad your whole family enjoyed them. They do make fantastic leftovers! :)
Made this tonight! It was delish! A easy and must new add to our monthly rotation!
I am so happy you liked my sheet pan fajitas Dianne! I love to hear it was easy to make and delish! Exactly what I was hoping for. So glad you will be making it again.
This recipe has been a total game changer in my house! Fajitas is a family favorite, and I love that It’s a meal I can make last and spread out for quick meals throughout the week (less cooking for me). Before this recipe fajita night meant a BIG mess in the kitchen using multiple pans! And it was always a 50/50 on whether the chicken would be too dry, too spicy or if the veggies would be over or undercooked.
With this recipe my fajitas are PERFECT, juicy, and flavorful every time – and I only have to clean a sheet pan and a cutting board! Plus the taco seasoning linked on this is perfection!
Sometimes I like to add cilantro and a squeeze of lemon juice to switch up the flavor (since we make this literally every week now). I also sometimes buy my bell peppers in bulk to cut up and freeze – so when I’m ready to make this I can throw the frozen veggies on the pan and they still cook perfectly!
Love that I can make a huge sheet and have meals all week. Great thrown on lettuce for a salad (no dressing needed), tossed in a tortilla for a quesadilla/burrito, and I’ve even used leftover chicken to make chicken tortilla soup.
If I could give this recipe 100 stars I would!
Omg and I forgot to mark the stars in my comment! *facepalm* so commenting again .
Oh my goodness Jessica! Thank you so much for the fantastic comment on my sheet pan fajitas! Your feedback really means the world to me! Isn’t it amazing how simple it is to make delicious fajitas every time? I also adore that the clean up is so easy! It is good to know that the recipe works well with frozen bell peppers. Thanks for sharing that.
Made these super easy fajitas tonight! The vegetables were so sweet and yummy and I used 2 thighs and 2 breasts. One of us likes dark meat and one likes white meat in our house. The chicken turned out juicy.
Isn’t it amazing how sweet and tasty the veggies get when you roast them Coleen? I am so glad your chicken turned out juicy. Thanks so much for your feedback!
Super easy, super simple, super fast, super delicious. We make this every week now for meal prep for the week ahead and I always look forward to meal time!
Yeah! I am so happy the fajitas were easy, simple, fast and delicious Kelsey! What more could you ask for? I love it! Even better that you make them once a week now. That is fantastic.
I’m at a point in life where I google whatever food/recipe I’m thinking of followed by “tastes lovely” and BAM it shows up and ALWAYS tastes amazing! This was delicious and so simple.
Oh my gosh! You just made my day Erika! I absolutely love that you google recipe ideas followed by my name! That is fantastic! I am so glad you liked my sheet pan fajitas. I am glad they turned out delicious and were simple to make.
Delicious! Had for dinner this evening and all my family loved it. Cleanup was a breeze too. Thanks for sharing.
I am so happy that you and your family enjoyed my sheet pan fajitas Sarah. I love a sheet pan dinner so much and it is great how easy clean up is.
Another Tastes Lovely recipe that is going in my regular meal rotation. I’m feeding a family of four and everyone loved this. It helps to meal prep the taco seasoning and queso if you want to add those. The rest is simple but delicious. The hubs and I put it over cauliflower rice and the kids filled tortillas. We all topped with Tastes Lovely guacamole. Highly recommend!
I am so glad you liked my fajitas April! Even better that your whole family liked it. I also love topping it with guacamole. I am thrilled will be part of your recipe rotation. That just makes my day!
So good! I made this in part of my meal swap with friends and her husband wont stop talking about how delicious it was! Love the easiness of this meal.
Yeah! I am so glad this was a hit! Happy it was easy and delicious!
Made this for the 3rd time today and it just keeps getting better and better! Love this recipe!
Yeah! So thrilled you have made this 3 times already! That absolutely makes my day Cheryl!
Another yummy recipe, so simple so good!
This is so easy and so delicious! I highly suggest you use her spice mix and don’t substitute it with a store bought one. The spice mix is perfect and not too salty like store bought ones normally are. So great for nights when you just don’t feel like cooking.
I am so happy you enjoyed the fajitas Isabelle! I am such a fan of homemade spice mixes. They are always so much more flavorful that store bought and you are right, much less salty.
So easy but oh so tasty!! This one will be a regular recipe in the rotation.
Yea! Thank you so so so much Judy! Glad you love it as much as we do!
