Hashed Beef (ハッシュドビーフ) is a classic Yōshoku (a Japanese version of Western cuisine, 洋食) dish that is made by simmering thinly sliced beef and vegetables like onion in a demi-glace or tomato-based sauce. While it has roots in British hash, the Japanese “Hashed Beef” has come to mean a rich, slow-simmered stew served over rice.
This recipe revolutionizes the traditional, long-simmering method of hashed beef, completing the dish in just 10 minutes! The moderate acidity of the tomato combined with the umami and richness from the secret ingredient, oyster sauce, achieves a deep, "well-simmered" flavor in a short time. Its ease makes it suitable for simple lunches or quick dinners when you’re tired but want a comforting, home-cooked meal.

Tips & Notes
・This recipe used canned tomatoes packed in purée. Canned tomatoes come in two varieties: those packed in juice and those packed in crushed purée. Adjust the amount of sugar depending on the type of canned tomato used. Using the juice-packed type will result in a thinner consistency.
・Substituting sake with red wine will result in a richer flavor.
・Adding salt while frying the onion accelerates dehydration, causing it to change color faster.
・Thoroughly frying the butter and beef increases the overall flavor and umami.
・The seasoning of this recipe is on the sweeter side; adjust the amount of sugar to taste.
・For meal prep: can be frozen for 3 weeks.
