Why I Love Sheet Pan Fajitas

Sheet pan meals have minimal dishes and everything is cooked together right on the same pan. These chicken fajitas are easy to make and require minimal prep. 

They make an excellent meal to prep in advance because they reheat well. You can make them for meal prep, or just have dinner ready earlier in the day for busy weeknights. 

The leftovers are also versatile. You can turn them into burrito bowls or use them in quesadillas.

Ingredients

  • onion
  • poblano pepper
  • red bell pepper
  • orange bell pepper
  • boneless skinless chicken brerast
  • fajita seasoning
  • salt & pepper
  • avocado oil
  • lime (optional)

Substitutions and Alterations

  • Onion – if you prefer red onion, you can use that in place of yellow or white. 
  • Poblano – The poblano can be replaced with green chiles or jalapenos. 
  • Bell peppers – use your favorite colors. I prefer red and orange, but green and yellow work great as well. 
  • Chicken breast – you can replace the chicken breast with chicken thighs. The cooking time will change, so be sure to adjust for that. 
  • Fajita seasoning – if you’re in a pinch, taco seasoning works well in this. I recommend just making your own though. Fajita seasoning is specifically paprika and cumin heavy which adds a nice flavor to this meal.
