Heat vegetable oil in a large cast iron pan, wok, or Dutch oven. Fill with enough oil to shallow fry or completely submerge.
For the chicken: cut each thigh into large bite size pieces and place in a large bowl. Season with salt and pepper, add the minced garlic, egg, flour, cornstarch and water. Mix well using your hands to coat each piece.
Fry each piece until golden on both sides and transfer to a wire rack. Repeat in batches until all the chicken is fried. For extra crispy, return for a double fry. Remove and season with some salt.
Gochujang sauce: Mix together all the ingredients and bring to a gentle simmer. Stir occasionally until nice and bubbly and the mixture has turned into a sticky sauce. About 5 minutes.
Asian slaw: Whisk together the mayonnaise, vinegar, honey, salt, pepper, sriracha, and lemon juice. Pour overtop the shredded cabbage and carrots.
Serve chicken over rice with a side of Asian slaw. Season with some sesame seeds and garnish with fresh cilantro. Enjoy!
