Roast Beef Sandwich with Horseradish Cream Sauce

Print Recipe
Serves 2


  • 2 tablespoons mayonnaise
  • 2 tablespoons sour cream
  • 1/4 teaspoon horseradish
  • 1/8 teaspoon paprika
  • kosher salt and pepper to taste
  • 1 tablespoon of olive oil
  • 1 tablespoon butter
  • 1/2 medium onion, sliced
  • 3 gloves of garlic, (2 minced, 1 left whole, you will use it to rub the toast)
  • 1/2 teaspoon each salt and pepper
  • 1/2 pound deli sliced roast beef
  • 4 slices Havarti cheese
  • 2 French rolls



Preheat your oven broiler.


Combine first 4 ingredients together in a bowl. Season to taste with salt and pepper. Cover and chill for 20 minutes while you prepare the rest of the sandwich.


In a skillet over medium heat add the olive oil and butter. Once the butter has melted add the onions and garlic. Cook until the onions caramelize, about 10-15 minutes. They should be turning a golden brown. Remove from heat and set aside.


Slice the French rolls in half and lay on a cookie sheet. Put under the broiler for about a minute. Remove from oven and rub the remaining garlic clove on the both sides.


On the bottom piece of each roll layer the roast beef, splitting the meat equally between the two sandwiches. Next, divide the onions evenly among the two sandwiches and place two slices of cheese on top of the onions. Place the tops and bottoms under the broiler until the cheese starts to melt.


Once the cheese has melted remove the sandwiches from the oven. Generously spread the horseradish cream sauce on the top portion of the french roll. Place the top on the rest of the sandwich and cut in half.
