• 5-6 pounds bone-in rib roast: The star of the dish, this cut offers juicy, tender meat with rich marbling that bursts with flavor when roasted.
• 4 tablespoons coarse sea salt: Essential for dry brining the roast, it draws out moisture and amplifies the natural beef flavors.
• 3 tablespoons freshly cracked black pepper: Adds a sharp, fragrant bite to balance the meat’s richness.
• 1 teaspoon garlic powder: Deepens savory notes, complementing the roasted garlic perfectly.
• 1 teaspoon mustard powder: Brings a subtle tang and complexity to the crust.
• 1 teaspoon minced fresh thyme: Lends a fresh, herbaceous aroma and taste.
• 1 (1.1 ounce) pack Johnny's French Dip Au Jus seasoning: Offers a flavorful base for the au jus sauce.
• 2 heads garlic: Roasted alongside the roast, they provide a sweet, buttery garlic spread to smear on each slice.
• 2 tablespoon extra-virgin olive oil: Keeps the garlic moist during roasting and adds richness.
• ½ cup heavy whipping cream, chilled: Whipped to soft peaks, this creates the creamy foundation for the horseradish sauce.
• ½ cup sour cream: Adds tanginess and smooth texture to the horseradish cream.
• ¼ cup mayonnaise: Offers richness and body to balance the horseradish’s heat.
• 3-6 tablespoons horseradish sauce: The star ingredient in the sauce for that signature sharp, zesty kick.
• 2 tablespoons minced chives: Provides a subtle onion note and fresh color.
• ½ teaspoon sea salt: Enhances all the flavors in the horseradish cream.

How to Make Prime Rib with Roasted Garlic and Horseradish Cream Sauce Recipe

Step 1: Dry Brine the Prime Rib

Start by preparing your prime rib the day before roasting. Line a baking dish with paper towels and place the roast inside. Rub it thoroughly with coarse sea salt, allowing the salt to penetrate overnight in the refrigerator uncovered. This dry brining process is key to developing a crusty, flavorful exterior and ensures the meat stays juicy and tender during cooking.

Step 2: Prepare the Horseradish Cream Sauce

While the meat is brining, get a head start on the horseradish cream sauce. Whip the chilled heavy cream in a small bowl until soft peaks form; this gives the sauce incredible lightness and body. Gently fold in sour cream, mayonnaise, horseradish sauce, chives, and a touch of sea salt. Chill this mixture to let the flavors meld beautifully. The sauce will add a refreshing, spicy contrast once your roast is ready.

Step 3: Season the Prime Rib

About two hours before roasting, combine black pepper, garlic powder, mustard powder, thyme, and half the Au Jus seasoning in a bowl. Rub this aromatic blend all over the prime rib, coating it evenly. Let the roast come to room temperature uncovered on your counter—they say good things take time, and letting the meat warm ensures even cooking and a lush texture.

Step 4: Roast the Prime Rib and Garlic

Preheat your oven to 450°F. Place the prime rib bone-side down in your roasting pan or ovenproof skillet. Trim the tops of the garlic heads just enough to expose the cloves, drizzle olive oil over them, wrap each head tightly in foil, and place them alongside the roast. Roast together for 20 minutes to jumpstart the Maillard browning, then lower the heat to 325°F and continue roasting for 60-70 minutes. Use an instant-read thermometer to check doneness—rare at 125°F, medium-rare at 135°F, or to your preferred level. Once out of the oven, let the roast and garlic rest for 20 minutes to lock in the juices.

Step 5: Make the Au Jus and Carve

While the meat rests, bring the roasting pan juices to a boil on the stove. Add the remaining Au Jus seasoning and a cup of water, whisking and reducing the liquid by half for a rich, flavorful sauce. Slice the prime rib thinly with a sharp knife and serve it alongside the luscious roasted garlic (simply squeeze the soft cloves out of their skins), the creamy horseradish sauce, and the savory au jus for dipping. Each component works harmoniously to elevate your meal to extraordinary.

How to Serve Prime Rib with Roasted Garlic and Horseradish Cream Sauce Recipe

Garnishes

Simple garnishes like fresh thyme sprigs or a sprinkle of finely minced chives on top of the meat add visual appeal and a pop of herbal brightness. A light drizzle of olive oil or a dusting of coarse sea salt over the sliced roast just before serving enhances texture and flavor. The roasted garlic cloves themselves make an irresistible, buttery garnish that guests will love spreading or eating directly.

Side Dishes

This prime rib pairs perfectly with classic sides such as creamy mashed potatoes, roasted seasonal vegetables, or crispy Yorkshire puddings. For a lighter option, consider a peppery arugula salad tossed with lemon vinaigrette to cut through the richness. The horseradish cream sauce complements both hearty and fresh accompaniments seamlessly.

Creative Ways to Present

To turn your Prime Rib with Roasted Garlic and Horseradish Cream Sauce Recipe into a feast for the eyes, arrange the sliced meat fanned out on a large wooden carving board surrounded by the roasted garlic heads and bowls of horseradish sauce and au jus. Alternatively, serve individual portions plated with a smear of garlic, a dollop of sauce, and sides artistically stacked or draped for a restaurant-style experience that will dazzle your diners.

Make Ahead and Storage

Storing Leftovers

Leftover prime rib makes fantastic next-day sandwiches or hearty additions to salads. Store slices tightly wrapped in foil or in an airtight container in the refrigerator for up to three days to maintain moisture and flavor.

Freezing

For longer storage, freeze sliced prime rib and sauce separately in airtight containers. Properly stored, the beef can last up to 2 months. Be sure to thaw overnight in the fridge to keep the texture intact.

Reheating

Reheat slices gently in a low oven (around 275°F) covered with foil to avoid drying out. For sauces, warm slowly on the stovetop, stirring frequently. This careful approach preserves the lusciousness and prevents toughness.

FAQs

What is the best way to check prime rib doneness?

The most accurate method is using an instant-read thermometer inserted into the thickest part of the roast. Aim for 125°F for rare, 135°F for medium-rare, adjusting to your preferred level. This helps avoid guesswork and ensures perfectly cooked meat.

Can I make the horseradish cream sauce in advance?

Absolutely! The horseradish cream sauce tastes even better after sitting overnight in the fridge, allowing the flavors to meld. Store it in an airtight container and give it a quick stir before serving.

Why do we dry brine the prime rib?

Dry brining with salt helps draw moisture from the meat and then reabsorb it, resulting in a juicier roast with a beautifully seasoned crust. It’s a simple step that elevates the overall flavor and texture.

Is roasted garlic difficult to prepare?

Not at all. Trimming garlic heads, drizzling with olive oil, wrapping in foil, and roasting alongside the meat creates soft, caramelized cloves that are easy to squeeze out and add sweet, mellow garlic flavor to your dish.

What sides pair best with horseradish cream sauce?

Rich vegetables like roasted carrots, creamy mashed potatoes, and even crispy onion rings complement the sharp, tangy qualities of horseradish cream wonderfully, balancing richness with bright heat.
