Teriyaki Beef Bowl

Instructions

1. Prepare the teriyaki sauce
   In a medium bowl, combine soy sauce, mirin, brown sugar, sake (if using), minced garlic, and grated ginger. Whisk until the sugar has completely dissolved.
2. Marinate the beef
   Place the thinly sliced beef in a large bowl and pour half of the teriyaki sauce over it. Reserve the remaining sauce for later. Gently mix to ensure all beef is coated and let marinate for 10 minutes while preparing other ingredients.
3. Cook the onions
   Heat vegetable oil in a large skillet or wok over medium-high heat. Add the sliced onions and cook until they become soft and translucent, about 3-4 minutes.
4. Cook the beef
   Add the marinated beef to the skillet with the onions. Cook, stirring frequently, until the beef is no longer pink, about 5-6 minutes. Be careful not to overcook as the thin slices cook quickly.
5. Add the remaining sauce
   Pour the reserved teriyaki sauce into the skillet. Bring to a simmer and cook for 2-3 minutes until the sauce thickens slightly and coats the beef.
6. Assemble the bowls
   Divide the cooked rice among four serving bowls. Top each bowl with an equal portion of the teriyaki beef and sauce.
7. Garnish and serve
   Sprinkle each bowl with sliced green onions and sesame seeds. Serve immediately while still hot.
