Easy Sheet Pan Fajitas

Easy Sheet Pan Fajitas are a weeknight staple. Nothing is better than delicious fajitas and only 1 pan and 1 bowl for cleanup. This simple dinner is a great recipe for keto sheet pan fajitas as well. The best part of the recipe is the paleo fajita seasoning.

Easy Sheet Pan Fajitas

This recipe is versatile and you can make it vegan very easily. You can also use chicken, steak, or even a portabella mushroom. Anything goes! 

The most important part of the recipe is the paleo fajita seasoning. I make a double batch of this and keep it in my pantry for easy dinners. 

Luckily, if your using chicken, steak, or mushroom you do not need to adjust the cook time. 

Alternatively, you could just add a couple extra bell peppers and onions as well. I love making a huge batch of this and having leftovers. 

Keto Sheet Pan Fajitas

My favorite way to keep this recipe low carb/keto and even paleo/whole 30 is to eat it on a salad.
