Pot Roast Sandwich

This is my take on the famous pot roast sandwich from the Hobnob Corner Restaurant in Nashville, Indiana. All of the food at the Hobnob is soooooo good, and their pot roast sandwich is no exception. It is insanely good. The pot roast is tender, herby, with a hint of wine, and juicy, while the creamy horseradish sauce adds just a little bite. Topped with caramelized onions, it’s the perfect sandwich.

Pot Roast SandwichI actually omitted the caramelized onions the first time I made this sandwich. It was still a great sandwich. As much as I used to not love horseradish I found it to be fantastic on this sandwich. It goes with the roast beef perfectly.

For the caramelized onions

  • 2 tablespoons unsalted butter
  • 2 medium yellow onions halved and sliced very thin
  • Kosher salt and freshly ground black pepper


  • Slather the bread with the horseradish sauce.
  • Add generous amounts of the pot roast.
  • Top with the cheese and place under the broiler long enough to melt the cheese.
  • Add onions and serve.
  • Note: If you have the juices leftover from making the pot roast, run it through a sieve and serve as a great dipping sauce.

For the caramelized onions:

  • Melt the butter in a large frying pan over medium-low heat until foaming.
  • Add the onions and cook them until they are deep golden brown and caramelized, about 45 minutes.
  • Season with salt and pepper.
  • Remove and let cool slightly before serving.
