Gyudon: the five-minute Japanese rice bowl

Gyudon is the dish that Japan's fast-food chains have built empires on. Yoshinoya, Sukiya and Matsuya together sell hundreds of millions of bowls of it per year. The reason is not a mystery: sweet, savoury beef and onions over rice, assembled in under five minutes, provides a satisfaction that is disproportionate to its simplicity. Made at home with good beef and properly made dashi, it is better than any chain version by a considerable margin.

The two elements that determine quality

Beef cut thickness and onion caramelisation. The beef should be sliced to about 2mm - thin enough to cook through almost immediately when added to simmering broth. This is either a task for a Japanese knife and some patience, or a conversation with a butcher. Ribeye or sirloin with visible marbling is the correct choice. Lean beef produces a dry, tough result.

The onions need to cook until genuinely translucent - about five minutes in the broth - before the beef goes in. Undercooked onions have a sharpness that clashes with the sweet broth. Well-cooked onions absorb the broth and become soft, sweet and almost indistinguishable from the sauce itself.

The broth

Combine dashi (or water with a piece of kombu), soy sauce, mirin, sake and a small amount of sugar. The proportions vary by preference, but the balance should be sweet-forward with a clear soy backbone. Taste the broth before adding the meat and adjust: more mirin for sweetness, more soy for depth, more dashi for lightness. Add the onions and broth together to a shallow saucepan or wide skillet and bring to a simmer.

Assembly

Once the onions are translucent, lay the beef slices across the top in a single layer and cook for two to three minutes. Do not stir aggressively - the beef should remain in flat sheets rather than breaking into small pieces. Spoon generously over hot steamed rice in a deep donburi bowl. Top with a soft-poached or onsen tamago egg, a pinch of beni shoga (pickled red ginger) and a sprinkle of shichimi if you like heat.

One good variation

Add enoki mushrooms to the broth alongside the onions. They cook in the same time and add a different texture and a subtle earthiness that suits the beef particularly well.
