Gulden's® Shaved Beef Sandwiches with Mustard

INGREDIENTS

• 6 tablespoons Gulden's® Spicy Brown Mustard, divided
• 1-1/2 teaspoons kosher salt
• 1/2 teaspoon ground black pepper
• 1/2 teaspoon dried thyme leaves
• 1/2 teaspoon dried rosemary, crushed
• 2-1/2 pounds beef eye of round or top round roast
• 1 tablespoon vegetable oil
• 4 cups beef broth
• 8 ciabatta buns
• 4 tablespoons softened butter
• 8 slices (1 oz each) Havarti cheese 

DIRECTIONS

Prep:

• Preheat oven to 425°F. Stir together 3 tablespoons mustard, salt, pepper, thyme and rosemary in small bowl. Rub mustard mixture over beef.

• Heat large nonstick skillet over medium-high heat. Add oil and beef to skillet. Cook beef on each side 2 minutes, until lightly browned. Remove to a baking dish and bake until internal temperature reads 135°F, about 40 to 50 minutes.

Combine:

• Pour beef broth into skillet and stir to remove browned bits. Simmer 10 minutes; set aside and keep warm. Use a slotted spoon to remove any large bits, if desired.

• Remove beef from oven and cover tightly with foil. Rest 15 minutes, until internal temperature reaches 145°F for medium rare.

Create:

• Place bun halves on baking sheet. Spread each evenly with butter. Bake 10 minutes, until lightly toasted.

• Spread remaining mustard evenly on bottom buns.

• Use a sharp knife to shave beef as thinly as possible. Divide beef evenly onto bottom buns.

• Top with cheese and top buns. Serve with warm au jus for dipping.
