I’m always on the hunt for easy dinner recipes that will feed a crowd and be a hit with the whole family, and I have a feeling that I’m not the only person out there with these specs in mind! Today’s Sheet Pan Chicken Fajitas dirty very few dishes, require few (if any) side dishes, and are enjoyed by adults and children alike.
We make fajitas in the skillet quite a bit, but since sheet pan fajitas seem to be the rage these days, I thought I’d give them a try. I was really happy with the results! I think that the longer cook time used in baking produces more tender chicken than frying does. Plus, I was able to put the veggies and chicken in the oven to bake and had half in hour in which to set the table, clean up the prep dishes, and get out all the various fajita accoutrements.
A loaded fajita is quite filling, so I didn’t even serve any sides with this meal. Everyone was stuffed! If you have voracious eaters, a nice salad or steamed veggie would be a good side item. If you go the Fuel Pull route with your fajita toppings, you could even serve these fajitas with a side of seasoned brown rice for a cheap THM:E meal!
These easy chicken fajitas can fit into any THM fuel type depending on what toppings you use; I’ve included suggestions in the printable recipe below.
I get a lot of questions about what low-carb tortillas I use. When purchasing low-carb tortillas, look for brands with 6g net carbs or less. (Subtract dietary fiber from the total carb count to calculate net carbs.) We just buy whatever our local discount grocery store happens to be carrying, so I’ve tried nearly every brand out there and couldn’t really pick a favorite.

- Spread the chicken, onion, bell pepper, and mushrooms on a sheet pan (with sides to hold the juices). Sprinkle with the cilantro, minced garlic, and seasonings, and pour the butter on top. Stir to coat. Bake at 350* for 25 minutes or until the chicken is cooked through.
- Serve with low-carb tortillas and your choice of toppings. Depending what toppings you use, this meal can be a THM:S or FP. If you choose the FP option, you could add a carb source to make an E meal.
When buying low-carb tortillas, look for a brand with 6g net carbs or fewer. I've used many different brands and usually just buy whatever my local discount grocery store happens to be carrying.

Oh my goodness this is so so yummy!!! I made it tonight thinking it’s quick and relatively healthy. But I was literally making “yummy” sounds while eating because I couldn’t believe how tasty this was (and so very quick to put together!). Definitely a keeper! Thank you!
I just made this for lunch with quinoa and 0% yogurt. So yummy! Thanks
I’ve made this at least twice and it’s always a hit! Great recipe!
This is awesome!!! Thank you! Taste like restaurant fajitas. ?
This is one of my favorites!! Fast, easy and delicious!! The onions taste amazing cooked this way….thanks!!
Just made this for lunch and OH MY!!! It is wonderful and so quick!! Thank you so much for all of the wonderful recipes!! I am enjoying your cookbook so much!
Hope you are enjoying Louisiana!
I certainly am enjoying LA, Patricia! So glad you liked the fajitas! (And the cookbook.)
This was delicious! We served it over cauliflower rice and loved it. We will definitely be adding it into our rotation!
OMGoodness!! This was the BEST! I will never buy fajitas at restaurants again!
Wait… peanut butter on fajitas??? Sounds amazing otherwise!!! Adding it to the menu for the week!
Did anyone ever try this with beef? or shrimp?
Made these tonight and they were scrumptious. Thanks for sharing all your great recipes.
We are having fajitas tomorrow, so I’m totally doing it this way. Thanks!
Do you eat 2 tortillas? I usually eat 2 & have never even thought about going over carbs. Do both combined need to be under 6g?
No, I can only ever handle one. Your net carbs from packaged items like tortillas need to come to 6g or less in total. 🙂
OK, Thanks! Also, I am loving the cookbook.
I thought it was 10g or less? I buy the Ole LC tortillas that are 5 net carbs each and eat 2. I’m still verrrry new to this, so is this wrong? Thanks!!
Good question! You can have 10g net carbs or less in a FP or S meal, but THM recommends that only up to 6g of that comes from “frankenfoods.”
This was a perfect Cinco de Mayo dish. My whole family loved it! Thank you.
I’m excited to try this asap. I’m always excited to see what new recipes are on your blog. Feeding a family of 7 is fun with new, healthy recipes to try!
You planned our supper! Thanks! As a busy Mom of 4 its wonderful to check e-mail and find my main meal of the day planned….We really like fajitas I’m eager to try the sheet pan method. Looks easier than the fry version that needs to be watched. God bless your day….
this looks awesome!!!!
