Serves 8-10
- 6lb Shoulder Roast
- 1/2 cup prepared horseradish
- 2 tablespoons finely chopped parsley
- 2 tablespoons Dijon mustard
- 1 tablespoon coarsely ground black pepper
- 1 tablespoon sugar
- 1 tablespoon sherry vinegar or red wine vinegar
Preheat the oven
Preheat the oven to 375°. Set a rack in a large, deep roasting pan and place the beef roast on the rack. (Remove roast from fridge at least 30 minutes to allow to come to room temperature).
Prepare the rub
In a small bowl, blend the horseradish with the Dijon mustard, chopped parsley, ground pepper, sugar and vinegar to form a paste. Slather the paste all over the top and sides of the meat.
Roast
Roast in the lower third of the oven for about 2 hours, until an instant-read thermometer inserted in the center of the roast registers 125°. Transfer the roast to a cutting board and let rest for at least 20 minutes.
Carefully cut strings. Thinly slice the roast beef across the grain. Transfer the meat to a platter and serve.
Make Ahead: The unsliced roast beef can be refrigerated for up to 3 days. The sliced roast beef can be wrapped in plastic and refrigerated overnight. Serve With Mashed potatoes.
