Prime Rib

Horseradish Cream

Natural Jus

Method

Preparing the Prime Rib

  1. 1

    Season the Roast

    Preheat the oven to 450°F (232°C). In a small bowl, mix together the kosher salt, black pepper, minced garlic, chopped rosemary, and olive oil. Rub this mixture all over the prime rib roast.

  2. 2

    Roast the Prime Rib

    Place the seasoned prime rib in a roasting pan. Roast in the preheated oven for 20 minutes, then reduce the temperature to 325°F (163°C) and continue roasting for about 1.5 hours or until the internal temperature reaches 130°F (54°C) for medium-rare. Remove from the oven and let it rest for 20 minutes before slicing.

Preparing the Pomme Purée

  1. 3

    Cook the Potatoes

    In a large pot, add the cubed potatoes and cover with water. Bring to a boil and cook until tender, about 15-20 minutes. Drain and return to the pot.

  2. 4

    Make the Purée

    Add the heavy cream, butter, and salt to the potatoes. Mash until smooth and creamy. Adjust seasoning to taste.

Roasting the Root Vegetables

  1. 5

    Prepare the Vegetables

    Toss the prepared carrots, parsnips, and beets with olive oil, salt, and black pepper in a large bowl.

  2. 6

    Roast the Vegetables

    Spread the vegetables on a baking sheet and roast in the oven for 30-35 minutes until tender and caramelized.

Making the Horseradish Cream

  1. 7

    Mix the Cream

    In a small bowl, combine the prepared horseradish, sour cream, lemon juice, and salt. Mix well and adjust seasoning to taste.

Preparing the Natural Jus

  1. 8

    Make the Jus

    In a saucepan, combine the beef broth, red wine, and fresh thyme. Bring to a simmer and cook for 15-20 minutes until slightly reduced. Season with salt and black pepper to taste.
