Prime Rib and Accompaniments

Method

Preparation Steps

  1. 1

    Prepare the Prime Rib

    Preheat your oven to 350°F (175°C). Season the prime rib with salt and pepper. Place it in a roasting pan and cook in the preheated oven for about 1.5 to 2 hours, or until the internal temperature reaches 130°F (54°C) for medium-rare. Let it rest for 20 minutes before slicing.

  2. 2

    Make the Natural Jus

    In a saucepan, combine the beef broth and drippings from the cooked prime rib. Bring to a boil and simmer for about 20 minutes until slightly reduced.

  3. 3

    Prepare the Horseradish Aioli

    In a bowl, mix together the mayonnaise and fresh horseradish. Adjust seasoning with salt and pepper to taste.

  4. 4

    Fry the Crispy Onions

    In a bowl, mix flour, salt, and pepper. Dip the thinly sliced onions into the buttermilk, then coat in the flour mixture. Heat oil in a deep skillet over medium heat. Fry the onions until golden brown and crispy. Remove and drain on paper towels.

  5. 5

    Assemble the French Dip

    Slice the buttered French rolls and pile in the sliced prime rib. Top with crispy onions and a generous dollop of horseradish aioli. Serve with small bowls of natural jus for dipping.
