Growing up in upstate New York as a life-long Bills fan, this sandwich tastes like home. But it transcends Buffalo as a beef masterpiece. The roast beef and jus make a for big bold beef flavor, the horseradish provides some adventurous kick and creaminess without overpowering, and the kummelweck roll is the perfectly salty vessel to hold it all together.
Technique tip: Try putting the seasoning on the meat a day ahead of time to better penetrate the roast.
Swap option: Can't find a kummelweck roll? Get some kaiser rolls, brush with an egg wash, sprinkle with pretzel salt and caraway seeds then bake at 350 F for 5 minutes, or until slightly brown and the egg wash is set.
- 1/4 cup mayo
- 1/4 cup sour cream
- 1 tablespoon buttermilk
- 2 tablespoons prepared horseradish, divided
- 1/2 teaspoon garlic powder
- 1/4 teaspoon Worcestershire sauce
- 2 grinds fresh black pepper
- 1 (3-pound) beef roast, such as top round or eye of ribeye
- 3 tablespoons beef rub, store-bought or homemade
- 1½ cups beef broth
- 6-8 kummelweck rolls
For the horseradish sauce:
In a small bowl, mix together all ingredients. Start with half of the horseradish and add more for a desired level of heat. Place in the fridge for at least 30 minutes and up to a day before using.
For the sandwiches:1.
Preheat a grill or oven to 450 F.2.
Cover the beef roast liberally with your favorite steak rub (alternatively, use kosher salt and freshly ground black pepper). Place it in a roasting pan with a rack with the beef in the rack and the broth in the pan. Let it rest on the counter for an hour and come to room temp.3.
Place the roast in the grill or oven. After 10 minutes, lower the temperature to 250 F. Continue to cook the roast until it hits an internal temp of 130 F to 135 F. Remove the roast and allow it to cool for 20 minutes.4.
Pour the beef stock jus into a saucepan (run it through a fine mesh strainer if you have one) and place on low heat.
Slice the beef as thin as you can. Pile it on the bottom bun and top with the horseradish sauce. Dip the top bun partially into the jus before putting it on top of the sandwich. For even more flavor, dip the beef in the jus before adding it to the sandwich or serve the sandwich with a side of jus for dipping.
