All About Oven Baked Chicken Fajitas

Interestingly, ‘fajitas’ is actually a TexMex recipe. This is my take on my favourite fajitas I’ve eaten in restaurants here and also in Mexico. If you’d like to learn about more authentic Tex Mex fajitas you can read about them (along with a recipe) at MuyBuenoKitchen.

There are so many ways to get that unmistakable and much-loved fajitas flavour, including Slow Cooker Fajitas and even Chicken Fajita Pasta.

But here we’re focusing on the simple and straightforward oven fajitas that are baked on a single sheet pan.

Chicken Fajitas Leftovers

In the fridge Simply fold them inside a tortilla and let them go cold. Put them in Tupperware and store them in the fridge for up to 3 days. They’ll be delicious for lunch the following day and shouldn’t be too messy as there’s not loads of sauce.

You could also use any filling up inside a Chicken Quesadilla too!

How to reheat Chicken Fajitas You can eat them cold or reheat them well in the microwave or in foil in the oven.

In the freezer The chicken fajita filling freezes fine, although it might be a little drier than when it’s freshly made. Just wait until it’s totally cold and then put into a freezer proof container and freeze for up to 3 months. Defrost thoroughly before reheating.

    So much easier than frying them – I am a complete convert. Means I can leave them prepped on a tray in the fridge ready for the teens to cook themselves!

    Your recipes really are a godsend Sarah 🙏

    1. Hi Amy, which chicken are you using? If you use frozen chicken this can happen as it has water added, otherwise it’s just the water from the vegetables. You could try your oven a little higher temperature, or just pour off some of the liquid halfway through cooking.
