This is basically a common Japanese fast food where beef and caramelized onions are served on top of short-grain rice. Perfect when hot, cold, or room temperature. Good for school lunches on hot days.
For the onion: While the recipe suggests a quick browning, extending this phase for a deeper, sweeter caramelization will significantly enhance the umami profile of the dish. Aim for a rich golden brown before adding liquids. Beef preparation: Ensure your ribeye is very thinly sliced against the grain for maximum tenderness. Partially freezing the steak for 15-20 minutes prior to slicing makes this task much easier and yields uniform pieces. Cooking the beef: Ribeye cooks quickly. Be careful not to overcook it, as it will become tough. Remove from heat as soon as it's just cooked through. Rice: Always serve Gyudon over freshly cooked, perfectly steamed Japanese short-grain rice. This is fundamental to the dish's integrity, allowing the savory sauce to be absorbed beautifully. Garnishes: The optional garnishes like green onions and pickled ginger are not merely decorative; they provide essential textural contrast and bright, piquant flavors that balance the richness of the beef. Do not skip them if possible.
