Step 1

Preheat a 6-quart air fryer to 400 degrees F.

Step 2

Whisk the soy sauce, sugar, mirin, sesame oil, garlic, 1/2 teaspoon pepper and 2 tablespoons water together in a large bowl until most of the sugar is dissolved and the marinade is homogenous. Set aside 1 tablespoon of the marinade in a medium bowl, add the zucchini and 1/4 teaspoon salt and toss well until coated. Add the beef to the remaining marinade and toss until the beef is well coated.

Step 3

Transfer the marinated beef to the air fryer basket and air fry until the ribeye is browned on top and cooked through, about 10 minutes. Carefully transfer the beef to a serving plate and without cleaning the basket transfer the marinated zucchini to the basket and air fry until the zucchini is browned on top and cooked through, 5 to 6 minutes.

Step 4

While the zucchini is cooking, tear the beef into bite-size pieces. Transfer the zucchini to the same serving plate with the beef and pour the residual marinade from the bottom of the air fryer over the beef. Sprinkle with sesame seeds and serve with rice.
