Recipe FAQs

Can I use chicken thighs instead of chicken breast? 

You can substitute chicken breast for chicken thighs! Just cut into strips the same way. 

How to know the chicken is done?

Since the chicken is sliced thin you can tell it is done just by the exterior. However, you can also use a meat thermometer to be sure. Chicken should reach an internal temperature of 165°F. 

Can I use frozen vegetables?

Fresh vegetables are best for getting a crispy and tender finish, but you can use frozen veggies if in a pinch. Be aware that frozen veggies may release excess moisture. 

Store & Reheat 

  • Storage. Leftovers can be stored in an airtight container, in the fridge for up to 3 days. 
  • Reheat. Warm fajitas on a skillet over medium-low heat until warm throughout. 
  • Freeze. You can freeze cooked fajitas by sealing them in a freezer-safe container and storing them for up to 3 months. Reheat: Let fajitas thaw in the fridge overnight before warming on a skillet over medium heat.
