In a medium bowl or plastic bag, combine the New York strip steak, oyster sauce, fish sauce, soy sauce, sugar, and black pepper and massage the steak to coat. Marinate for 10 minutes at room temperature.
Preheat the air fryer to 425°F (220°C).
Add the steak to the air fryer and cook for 5–6 minutes on each side, until caramelized on the outside and the internal temperature registers 135–145°F (57–63°C) on an instant read thermometer, depending on your desired doneness. Transfer the steak to a cutting board and let rest for 10 minutes.
Meanwhile, make the jeow: In a medium bowl, stir together the fish sauce, sugar, MSG, chile flakes, toasted rice powder, kaffir lime leaves, lime juice, and scallions until the sugar is dissolved. Stir in the bird’s eye chiles. Set aside until ready to serve.
Thinly slice the steak against the grain. Drizzle the jeow over top and garnish with the mint and cilantro. Serve with sticky rice.
