Roast Beef & Horseradish Recipe

Cooking Instructions

1. 1

   Prepare the Roast Beef

   Preheat the oven to 300°F (150°C). Season the roast beef with salt and pepper, and place it in a roasting pan. Roast for 3-4 hours or until it reaches your desired doneness. Let it rest for 20 minutes before slicing.

2. 2

   Caramelize the Onions

   In a skillet over medium heat, add a tablespoon of olive oil. Add sliced onions and cook, stirring occasionally, until they are golden brown and caramelized, about 20-25 minutes.

3. 3

   Prepare Roasted Red Peppers

   If using fresh red peppers, roast them over an open flame or in the oven until the skin is charred. Place them in a bowl covered with plastic wrap for 10 minutes, then peel off the skin and slice.

4. 4

   Assemble the Sandwich

   Layer the sliced roast beef on a slice of sourdough bread. Top with caramelized onions, roasted red peppers, provolone cheese, and a generous spread of horseradish mayo. Close the sandwich with another slice of sourdough.

5. 5

   Grill the Sandwich

   Heat a skillet or grill pan over medium heat. Place the sandwich on the pan and grill until the bread is golden brown and the cheese is melted, about 3-4 minutes per side.

6. 6

   Serve

   Slice the sandwich in half and serve warm.
