RECIPE FOR ROAST BEEF SANDWICH RECIPES

Steps:

• For the au jus: Heat the oil over medium heat in a medium saucepan. Add the peppercorns, salt, thyme, garlic, rosemary and shallots. Cook the shallots, stirring occasionally, until they become translucent, 6 to 8 minutes. Add the sherry and simmer, a few minutes. Add the stock and simmer, 20 to 25 minutes. Remove the saucepan from the heat and strain the liquid. Keep warm. 
• For the pickled radishes: Simmer 1/2 cup water, the vinegar, sugar, coriander seeds, salt, star anise, bay leaf and garlic. After 10 minutes of simmering, pour the mixture over the radishes in a heat-proof container and cool. 
• For the sandwich build: Place the bottom halves of the rolls on a work surface. Place the sliced Homemade Roast Beef on the bottom. Top with 1 slice gruyere each, some pickled radishes and watercress. Cover with the tops of the rolls. Cut each sandwich in half, dunk into the au jus and realize sometimes leftovers are just better.
• Preheat the oven to 400 degrees F. Mix the rosemary, thyme, salt, pepper and garlic in a small bowl. Rub the mixture all over the roast, cover with plastic wrap and refrigerate, about 20 minutes. 
• Heat the oil in a large heavy skillet over high heat. Wipe off the excess garlic and herbs and add the roast to the pan. Sear the roast on all sides, 2 to 3 minutes per side. Transfer the roast to a roasting pan with a rack. Roast until an instant-read thermometer inserted into the center registers 125 degrees F, about 50 minutes. Transfer the roast to a cutting board and let rest, about 10 minutes. Thinly slice the roast and serve. 

Steps:

• In a small bowl, mix together the onion and 1 tablespoon of the salt. Set aside for 20 minutes. Rinse the onions with cold running water. Drain and squeeze to remove excess liquid. Combine the onions and the vinegar and marinate at least 30 minutes or up to 24 hours.
• In a small bowl, mix together the mayonnaise, sour cream, horseradish, zest, and 2 teaspoons salt. Season generously with pepper and hot sauce to taste. Refrigerate the horseradish sauce for at least 30 minutes.
• Preheat the broiler. Slice the rolls in half lengthwise. Using your hands, shallowly scoop out the inside of each half. Transfer the rolls to a baking sheet and arrange scooped-side up. Toast the rolls under the broiler for about 1 minute. Slather the inside of the rolls with the horseradish sauce. On each of the roll bottoms, layer 2 tomato slices and season with salt and pepper to taste. Top the tomatoes with some of the roast beef overlapped into "ruffles" and season with salt and pepper. Top the meat with some of the onions and watercress and cover with the tops of the roll. Serve immediately.
