Instructions

  1. 1

    Rub the beef roast all over with oil, salt, and pepper.

  2. 2

    Roast at 450°F (230°C) for 15 minutes. Lower the heat to 325°F (163°C), add the onion halves, and roast 1 to 1.5 hours until 130°F (54°C).

  3. 3

    Let the roast rest for at least 20 minutes. Save all the pan drippings.

  4. 4

    Stir the pan drippings and beef stock together in a saucepan. Simmer for 15 minutes to make the au jus (thin gravy), then season with salt and pepper.

  5. 5

    Brush the kaiser rolls with a little water, then sprinkle with caraway seeds and pretzel salt. Warm briefly in the oven.

  6. 6

    Slice the rested roast beef very thinly across the grain.

  7. 7

    Quickly dip the cut side of each roll in the hot au jus. Pile the sliced beef high on the rolls.

  8. 8

    Serve right away with extra au jus for dipping and horseradish on the side.

Chef's tips

Slice the roast beef paper-thin against the grain once well rested — thick slices make the sandwich hard to bite through.

Storage

Refrigerate sliced roast beef and jus separately for up to 4 days.

Reheating

Warm the jus gently on the stovetop; keep the beef cold or just at room temperature rather than fully reheating it, to preserve tenderness.

Common mistakes to avoid

  • Overcooking the roast past medium-rare, which turns thin slices tough and dry.
  • Skipping the caraway-and-salt topping on the roll, which is what makes it a true kummelweck.
  • Serving without horseradish, an essential element of the classic sandwich.
