Oven-Baked Chicken Fajitas

This Oven-Baked Chicken Fajitas freezer meal recipe is near and dear to my heart…and my stomach!

I love this easy chicken fajita recipe because it has great, bold flavors, without being too spicy.  It is easy to prepare, and best of all, it cooks in the oven in just 20 minutes!  You can dress this fajita mix up or down, however your heart desires.  It can be an evening dinner-plate stunner, or a late-night low-key “eating dinner on the couch in front of a good show after a long day” comfort.  So versatile!

This is also what is often lovingly referred to as a dump style freezer meal, meaning you do minimal prep on the ingredients, then dump them all in a freezer bag, and stick it in the freezer.  No pre-cooking needed.  Then on cooking day, you pull it out, dump the contents into your baking dish, and bake.  Dump and freeze, then dump and bake.  Easy peasy.

Or skip the freezer part all together and make from fresh – like I said, she’s versatile!

Ingredients and Prep

Nothing terribly fancy here, just your good, solid, hearty standards – chicken breasts, bell peppers, onion, and some warm spices to give it some zing.

Really, the only prep you need to do on this one is to cut up your chicken, and then slice your onion and bell peppers.  I put the ingredients in bowls in order to get a good picture, but when you’re making this at home, just skip that step!  No need to dirty any more dishes than you have to.

(You might notice that my chicken is cubed instead of cut into thin strips like traditional fajita meat – I do this simply because my little ones don’t handle the longer pieces of meat very well. You can cut your’s however you prefer.)

Freezing the Chicken Fajita Mix

To make the Oven-Baked Chicken Fajitas as a freezer meal, simply place your chicken, onions and bell peppers directly into a gallon-size freezer bag.  Then add in the oil and spices.  Remove as much air as possible, seal it tightly and then knead the ingredients to mix.

(If you’re not using this as a freezer meal and will cook this directly from fresh, skip the bag and place your chicken, peppers and onions straight into a 9×13 dish, then add the oil and spices and toss to coat.)

Make sure to label your bag and include the date and cooking instructions.

Then into the freezer we go!  If possible, lay your bag out flat as it freezes.  This will help save space.  Then, once frozen, you can stack it with additional meals, or even turn it upright to stack it like you would a book on a bookshelf.

You’ll want to pull this simple chicken freezer meal out the night before, and let it thaw in the refrigerator.  When you’re ready to cook, pour the contents of the bag into a 9×13 baking dish, and bake at 400 degrees Fahrenheit for 20-25 minutes until the chicken is cooked through and the peppers are soft.  Serve with warmed tortillas and your choice of toppings, add-ons, or whatever strikes your fancy.

Have Your Fajitas and Stay Keto, Too!

This easy chicken fajita recipe is great for keto folks!  Actually, it’s great for ANY folks! 

I especially like it because I can make it for dinner for the whole family, and those who are not restricting carbs can have their normal fajitas with their flour tortillas, and those eating keto can skip the tortillas but still get a great filling meal! 

Or go one further and serve with cauliflower rice, avocados, shredded cheese and sour cream for a keto chicken fajita burrito bowl!

Update: I had someone ask me this week if this meal would work in the slow cooker instead of the oven, and I am happy to report that I tried it yesterday in said slow cooker and it worked great!! (Cook on low for 3-4 hours.)  I happen to prefer it done in the oven, because chicken breast sometimes tends to get a little dry in the slow cooker with the long low heat.  But it is still totally doable and you might not even notice a difference, especially once it’s inside a nice warm tortilla wrapped up with all your favorite toppings!

How long are these good in freezer?


Tuesday 16th of May 2023

For best taste and texture you’ll want to use within about 3 months. (I’ve left mine in for 6+ months without any ill effects but it will really depend on how you package and store it, so shoot for within 3 months for your first try.). The main concern will be avoiding freezer burn on the chicken.

Absolutely love this recipe! I have tried several freezer recipes and this one is at the top of my list. We camp often and it’s so nice to pull a dinner out of the freezer and have dinner on the table in 30-45 minutes. It’s just 2 of us, so this recipe made two dinners for us. Thank you!

I’m so glad you liked it!! It is one-off my personal favorites. 😉

My family loves fajitas! If I doubled the recipe per freezer meal would it still be okay to use a 9x13 baking dish?


Wednesday 10th of August 2022

Yes - I often double it myself. ;) You might need to add just a bit to the cook time if the pan is extra full and stir about halfway through.

I stumbled in this recipe while trying to figure out a quick way to take several meals to several people who are sick or dealing with a surgery or new baby. I quadrupled this recipe and made a huge batch of Spanish rice in the instant pot so my family could have a hot dinner, but also so I could take dinner to several families in need. This is the BEST, easiest fajita chicken I have ever tasted, and the veggies came out fantastic too. So much easier, so much tastier than pan-fried! This is a keeper for sure, thank you so much for publishing it. It’s been a blessing to many families in my area, and so easy for me to batch-cook a ton of it for families in need.

Oh my goodness, you are so very welcome! What a kind thing to say!! Thank you! I'm so glad you like them!


Wednesday 10th of July 2019

I am wanting to make this recipe!! But I am curious do the peppers turn out to be soft/soggy tasting? or do they hold more of a crunch cooked texture? curious to see if it would be better dividing the meat and the veggies and cooking veggies in skillet at eating time.


Wednesday 10th of July 2019

If cooking from fresh (not previously frozen) they are fairly crisp if you cook just until the chicken is done (onions will be soft but peppers will still have some crunch). If you are cooking after it has been frozen and thawed, then the peppers will be soft. Not soggy, but soft. You can absolutely prep the chicken alone and leave the veggies out (so freeze the chicken and spices but not the onions or peppers) until you're ready to cook! Or just make it entirely from scratch and cook (don't freeze). Hope that helps!
