Pat the chicken thighs dry with a paper towel, then use kitchen shears to carefully remove the bones, along with any joints or cartilage. Pound the chicken flat with a meat pounder, or you can make cuts on the thick parts of the chicken so the meat is even in thickness.
4 bone-in, skin-on chicken thighs
Season the chicken with salt and pepper, then toss the chicken with cornstarch so it’s evenly coated.
Salt and pepper, 3 tbsp cornstarch
On a large COLD skillet, spread avocado oil and add the chicken skin-side down in a single layer. Turn the heat to medium heat and once the chicken starts to sizzle, cook for 7 minutes until the skin is browned and crispy (you may need a splatter guard), then flip and cook for 5 more minutes until the chicken is fully cooked (internal temperature of 165). Remove the chicken and set aside, leaving the chicken fat in the pan.
2 tsp avocado oil
With the stove still on, add the white part of the green onions and garlic to the chicken fat. Saute for 1 minute.
4 garlic cloves, 4 green onions
Turn off heat, then immediately add the green parts of the green onions, tamari sauce, oyster sauce, sesame oil, and sugar. Stir until the sugar is dissolved.
4 green onions, 2 tbsp tamari sauce, 1½ tbsp oyster sauce, 1 tbsp sesame oil, 1 tsp sugar
Serve the chicken with rice, then drizzle with the scallion sauce on top of the chicken. Enjoy!
