• Before You Start…Please note that this recipe requires at least overnight marinating time. 

To Make the Negi Miso Sauce

• Gather all the ingredients. Cut the green part of 1 Tokyo negi (naga negi; long green onion) into fine rounds.
  
• Heat a large frying pan over medium-high heat. When it‘s hot, add 1 Tbsp toasted sesame oil. Then, add the sliced negi and stir-fry until wilted.
  
• Lower the heat to medium low. Add 3 Tbsp miso, 1 Tbsp sugar, 2 Tbsp mirin, 2 Tbsp sake, ½ tsp soy sauce, and 1 tsp ginger (grated, with juice) and stir to combine. It burns easily because of the miso, so keep stirring while you cook. When most of the liquid has evaporated, turn off the heat and let cool.
  

To Make the Negi Miso Chicken

• In a bowl or resealable plastic bag, combine 1 lb boneless, skinless chicken thighs with the negi miso sauce. Marinate for at least overnight.
  

To Cook the Negi Miso Chicken

• Heat a large frying pan on medium heat. When it‘s hot, add 1 Tbsp neutral oil. Remove the chicken from the marinade, wiping off as much of it as you can since miso burns easily (and reserving the marinade to make a sauce later). Add the chicken to the pan. Cook the chicken until golden brown, then flip. Reduce the heat and cover the pan with a lid. Let the chicken cook until fully cooked through, then transfer it to a plate.
• Add the reserved negi miso marinade to the pan. Add 4 Tbsp water (or you can use sake) and stir. Bring it to a boil, then let it simmer for a few minutes (as the raw chicken was in the sauce). Serve the chicken immediately with the negi miso sauce. Enjoy!

To Store
