Rocky Mountain Roast Beef Recipe

Directions

1. 1

   Prepare the Roast

   Preheat your oven to 325°F (160°C). Season the beef roast with salt, pepper, and garlic powder. Place it in a roasting pan and roast for about 1.5 to 2 hours, or until the internal temperature reaches 135°F (57°C) for medium-rare.

2. 2

   Cook the Bacon

   While the roast is cooking, in a skillet over medium heat, cook the bacon until crispy. Remove and set aside on paper towels to drain.

3. 3

   Sauté the Vegetables

   In the same skillet with some of the bacon grease, add olive oil if needed. Sauté sliced onions and mushrooms until they are soft and caramelized, about 8-10 minutes. Season with salt and pepper to taste.

4. 4

   Assemble the Sandwich

   Once the roast is done, let it rest for 10 minutes before slicing thinly. On each bun, layer the roast beef, sautéed onions and mushrooms, bacon, and top with Swiss cheese.

5. 5

   Melt the Cheese

   Place the assembled sandwiches in a preheated oven or under a broiler just until the cheese melts, about 2-3 minutes.

6. 6

   Serve

   Serve the sandwiches warm with your favorite side or dipping sauce.
