We are not thinkin' Arbys-- not after a roast beef sandich like this one. A classic creamy cheese sauce makes this sandwich super rich, while a horseradish sauce adds a kick. We love the onion bun, preferaby bakery-made, but you could also use a pretzel bun instead. Make this sandwich the centerpiece of your Super Bowl Spread or serve along with beer and fries for a crowd-pleasing meal.  

Ingredients

  • 8 ounces extra-sharp Cheddar cheese, grated (about 2 cups)
  • 1 tablespoon cornstarch
  • 1 (12-oz.) can evaporated milk
  • 2 teaspoons hot sauce
  • 1 (1.5-oz.) onion rolls, split
  • 1/2 cup sour cream
  • 1/4 cup mayonnaise
  • 2 tablespoons thinly sliced fresh chives
  • 3 tablespoons prepared horseradish
  • 1 tablespoon fresh lemon juice
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 2 pounds thinly sliced Perfect Roasted Beef Tenderloin

How to Make It

  1. Preheat oven to 300°F. Combine cheese and cornstarch in a medium saucepan. Stir in evaporated milk and hot sauce; cook, whisking constantly, over low until sauce is bubbly and well combined, about 5 minutes. Remove from heat; keep warm.

  2. Wrap rolls in aluminum foil; bake in preheated oven until thoroughly heated, about 10 minutes.

  3. Meanwhile, combine sour cream, mayonnaise, chives, horseradish, lemon juice, salt, and pepper in a small bowl. Spread sour cream mixture on cut sides of bottom halves of rolls; top each with 4 ounces Beef, and drizzle each with 3 tablespoons Cheddar sauce. Cover with top halves of rolls; serve immediately with remaining Cheddar sauce, if desired.
