Ingredients
  

  • 3 Pounds boneless skinless chicken
  • 2 Stalks lemongrass chopped
  • ¼ Cup vegetable oil
  • 2 Thai chilis
  • 5 Cloves garlic
  • 3 Tablespoons purple onion thinly sliced
  • 2 Tablespoons corn starch

Lemongrass Marinade

  • ¼ Cup soy sauce
  • ¼ Cup fish sauce
  • 4 Tablespoons brown sugar
  • 3 Tablespoons lemon juice
  • 2 Tablespoons grated ginger
  • 1 Tablespoon dried lemongrass
  • 1 Tablespoon sriracha
  • 1 Tablespoon lemon zest

Instructions
 

  • Mix all of the ingredients for the Lemongrass Marinade. Chop the stalks of lemongrass. Add only 2 tablespoons of the fresh chopped lemongrass stalk to the marinade. Set the remainder aside for later. Stir the marinade until fully combined. Reserve half of the marinade and set aside.
  • Slice the boneless skinless chicken into thin 1-inch strips and add to a mixing bowl. Pour half of the marinade over the boneless skinless chicken and stir until fully combined. Allow to sit for at least 10 minutes.
  • In the meantime, chop the Thai chilis and garlic. Thinly slice the purple onion. Add the corn starch to the remaining marinade and stir to make a slurry. Set aside.
  • Heat a pan sprayed cast iron skillet on medium heat. Add vegetable oil. Add all of the marinated chicken to the pan. Allow to cook for 15-17 minutes, stirring occasionally. Turn the heat up to medium high. Allow the chicken to cook for an additional 5-6 minutes until cooked through and until the desired browning and caramelization is reached.
  • Turn the heat back down to medium. Add the remaining chopped lemongrass stalk, Thai chilis, garlic and purple onion. Cook for 2-3 minutes while stirring to combine with the chicken. Add the Lemongrass Marinade slurry and stir for two minutes. Serve with Jasmine rice and enjoy!
