Ingredients for the Meat and Beans

  • 600 g whole beef sirloin
  • 1 tablespoon olive oil
  • 30 g Dijon mustard
  • 17 g salt (for meat and beans combined)
  • 2 teaspoons colorful peppercorns

Additions for the Green Beans

  • 500 g green beans (fresh or frozen)
  • 3 teaspoons ume vinegar

For Serving

  • 100 g cranberry sauce or preserve

Preparation and Roasting

  • 1
    Take the meat out of the refrigerator one hour before roasting to bring it to room temperature. Coarsely crush the colorful peppercorns in a mortar.
  • 2
    Clean the meat of any membranes, then tie it with kitchen twine to help it keep its shape. Season thoroughly with salt and rub in the coarsely crushed peppercorns.
  • 3
    Preheat the oven to 140 °C (top and bottom heat).
  • 4
    Heat one tablespoon of olive oil in a hot pan and sear the meat quickly on all sides (about 1-2 minutes per side) to seal in the juices.
  • 5
    Place the meat on a baking tray and spread generously with Dijon mustard. If you have a meat thermometer, insert it into the center of the meat. Roast for about 40 minutes, or until the internal temperature reaches 50-55 °C (medium-rare).
  • 6
    After roasting, remove the meat and let it rest for at least 10 minutes before slicing thinly.

Preparing the Side Dish and Serving

  • 1
    Wash the green beans and steam or boil them in hot water for about 7 minutes until crisp-tender. Immediately drain them and plunge into ice water to preserve their vibrant color. Finally, drain well, drizzle with ume vinegar, and season with a pinch of salt.
  • 2
    Serve the thinly sliced roast beef with green beans and a portion of cranberry sauce.
Tip
Always slice the meat against the grain after resting to ensure it remains as tender as possible.
