Step 1
Start by cutting the onion in half and removing the tough center part. Slice the halves thinly. Heat a little oil in a large skillet or wok over high heat, then toss in the onion. Cook and stir it for about 30 seconds until it just starts to brown. Turn the heat down to medium-low and add water, soy sauce, brown sugar, mirin, and sake. Let everything simmer together for about 3 minutes so the flavors blend nicely. Next, add the beef to the pan, cover it, and cook until the meat is done—this should take around 3 to 5 minutes. Once everything is cooked, divide the beef and sauce between bowls and sprinkle with sesame seeds, chopped green onions, pickled ginger, and some seaweed strips for a tasty finish.
