Ingredients

  • 500 g beef (thinly sliced)
  • 1 onion (sliced)
  • 1 carrot (sliced)
  • 200 g mushrooms (sliced)
  • 2 tbsp vegetable oil
  • 2 tbsp flour
  • 300 ml beef stock
  • 2 tbsp ketchup
  • 2 tbsp Worcestershire sauce
  • 1 bay leaf
  • Salt to taste
  • Pepper to taste
  • Cooked rice (for serving)

Steps

  1. In a large pan, heat 2 tablespoons of vegetable oil over medium heat. Add the sliced beef and cook until browned, about 5 minutes. Browning the meat enhances flavor through the Maillard reaction.

  2. Add sliced onions, carrots, and mushrooms to the pan. Sauté for about 5 minutes until the vegetables soften, releasing their flavors into the dish.

  3. Sprinkle the flour over the mixture and stir for 1-2 minutes to create a roux, which will thicken the sauce.

  4. Gradually add 300 ml of beef stock while stirring to avoid lumps. Bring the mixture to a simmer and add ketchup, Worcestershire sauce, and a bay leaf. Simmer for 10 minutes until the sauce thickens.

  5. Season with salt and pepper to taste. Remove the bay leaf before serving.

  6. Serve the beef hash over a bed of warm cooked rice, ensuring the sauce is generously spooned on top.

Why this works

The technique of making a roux is crucial for achieving a smooth and rich sauce, serving as a base for the flavors to meld together. By sautéing the beef and vegetables first, you're developing complex flavors that create depth in the dish. The addition of ketchup and Worcestershire sauce contributes to a sweet and tangy balance, while the beef stock provides the necessary umami. If the sauce seems too thick, you can easily adjust it by adding a bit more beef stock or water to reach your desired consistency. Conversely, if the sauce is too thin, continue simmering it uncovered to reduce and thicken further. This dish showcases the fusion of Western cuisine with Japanese tastes, making it a beloved staple in yoshoku (Western-style Japanese cuisine).
