Prime Rib with Horseradish Butter Recipe Ingredients

Prime Rib:

• 2 sticks (1 cup) unsalted butter, at room temperature
• 1/4 cup prepared horseradish
• 2 tablespoons mixed or tri-color peppercorns, coarsely cracked
• Kosher salt
• One 7- to 8-pound boneless prime rib roast

Sauce:

• 2 cups sour cream
• 2/3 cup prepared horseradish, drained
• Kosher salt and freshly ground black pepper
• 1 bunch fresh chives, coarsely chopped (about 3/4 cup)

How To Make Prime Rib with Horseradish Butter Recipe

1. Preheat and Prep: Preheat the oven to 500 degrees F. Ensure your butter is completely soft at room temperature for easy mixing.
2. Make the Compound Butter: In a medium bowl, combine the softened butter, 1/4 cup prepared horseradish, cracked peppercorns, and 2 tablespoons of kosher salt. Stir until evenly combined into a thick paste.
3. Season the Roast: Slather the seasoned horseradish butter evenly over the top and sides of the roast (leave the bottom bare). Place the roast on a rack set in a large roasting pan.
4. The High Heat Blast: Roast the beef for 35 to 40 minutes (calculate roughly 5 minutes per pound). This high heat creates the signature dark golden brown crust.
5. The “Oven Off” Method: After the initial roast time, turn the oven off. Let the roast sit inside the oven for 1 1/2 hours. Do not open the oven door during this time. The residual heat will finish cooking the beef to a perfect medium-rare without drying it out.
6. Make the Sauce: Meanwhile, whisk the sour cream, drained horseradish, 2 teaspoons salt, and 1 teaspoon pepper together in a medium bowl until well combined. Stir in the fresh chives. Cover and refrigerate until ready to serve.
7. Serve: Remove the roast from the oven. Cut it into 1-inch-thick slices and serve with the cool horseradish sauce.

Recipe Tips

• The “Closed Door” Rule: The success of this method relies entirely on trapping the heat. If you open the door to peek, the heat escapes, and the roast won’t cook through. Tape a note to the oven door if you have to!
• Butter Temperature: The butter needs to be very soft so you can massage it over the meat without it falling off in chunks.
• Drain the Horseradish: For the sauce, make sure to drain the liquid from the jarred horseradish before mixing it with the sour cream. If you don’t, the sauce will be watery.
• Cracked Peppercorns: Use a mortar and pestle or the bottom of a heavy skillet to coarsely crack the peppercorns. You want texture/crunch, not fine dust.
• Timing the Meal: As noted, this requires working backward. If you want to eat at 6:00 PM, the roast needs to go into the oven around 4:00 PM (40 mins active roast + 90 mins sitting).

What To Serve With Prime Rib with Horseradish Butter Recipe

This rich, buttery roast needs classic steakhouse sides.

• Yorkshire Pudding: To soak up any drippings.
• Creamed Spinach: A classic pairing.
• Roasted Potatoes: Crispy roasted potatoes or garlic mashed potatoes.
• Glazed Carrots: For a sweet contrast to the peppery beef.

How To Store Prime Rib with Horseradish Butter Recipe

• Refrigerate: Store leftover beef in an airtight container for up to 3 to 4 days. Keep the sauce refrigerated separately; it stays fresh for 5-7 days.
• Reheat: Gently reheat slices in a skillet with a little butter or beef broth just until warm. Do not microwave high heat or the meat will turn gray and tough.
• Freeze: You can freeze the cooked beef wrapped tightly for up to 3 months. Do not freeze the sour cream sauce as it will separate.
