Oven Chicken Fajitas in less than 30 minutes

This easy baked fajitas are a super simple dinner recipe that I make 2 or 3 times a month. It only takes a few minutes to throw together and then it goes in the oven until dinner is served.

It makes a tasty keto friendly meal. To keep your macros in check, you can serve them with keto-friendly tortillas, on their own, or over spanish cauliflower rice

If you are not following a keto diet, you can serve baked chicken fajitas over your favorite rice, with beans, or in regular tortilla shells. 

They’re a fun way to switch up taco night along with our keto tacos, chicken enchilada casserole, or some awesome taco zucchini boats.
