What Cut of Meat Should I Use for Prime Rib Roast?

You want to go with a bone-in prime rib roast, sometimes labeled as a standing rib roast. The bones add flavor and help insulate the meat during roasting, promoting an even cook. A 3 to 5 bone roast is ideal for most gatherings. Be sure to ask your butcher for a well-marbled piece—marbling ensures tenderness and rich taste.

Options for Substitutions

• Fresh Herbs: If fresh herbs aren’t available, dried ones can work in a pinch—just use about one-third of the amount since dried herbs are more concentrated.
• Garlic Paste: Garlic powder can substitute in emergencies, though it lacks the pungency of fresh garlic.
• Butter Substitute: Olive oil or ghee are good alternatives to butter, especially if you need a dairy-free version.
• Mustard Base: Dijon mustard adds a tangy kick to the crust, but you can use horseradish for a sharper flavor profile.
• Boneless Roast: You can use boneless rib roast, just adjust cooking time slightly as it may cook faster without the bone.

Ingredients for Herb Crusted Prime Rib Roast

• Prime Rib Roast (Bone-In): The star of the show. Choose a well-marbled, bone-in cut for maximum flavor and tenderness.
• Fresh Garlic: Crushed or finely minced, garlic brings bold, aromatic flavor to the crust.
• Fresh Rosemary: A key herb that pairs beautifully with beef. It adds earthy and pine-like notes.
• Fresh Thyme: Adds another layer of herby brightness to the crust.
• Kosher Salt: Essential for seasoning the roast deeply and drawing out its natural flavors.
• Cracked Black Pepper: Adds a bit of spice and balance to the salt and herbs.
• Dijon Mustard: Acts as a binder for the crust and gives a subtle tanginess.
• Unsalted Butter: Softened, it forms the base for the herb paste and helps create a golden-brown crust.
• Olive Oil: A drizzle helps with even searing and enhances the herb blend.
• Optional: Horseradish or Worcestershire Sauce: For a punch of sharp, savory depth if you want to experiment with bold flavors.

Step 1: Prepare the Prime Rib

Take the prime rib out of the refrigerator and let it sit at room temperature for at least 2 hours. This ensures even cooking. Pat it dry with paper towels to help the crust adhere better later on.

Step 2: Mix the Herb Butter Crust

In a bowl, combine softened butter, minced garlic, chopped rosemary, thyme, salt, pepper, and Dijon mustard. Mix until it forms a thick, aromatic paste. Add a touch of olive oil if needed for easier spreading.

Step 3: Coat the Roast Generously

Rub the herb butter crust all over the surface of the roast, including the sides and in between the bones. Be generous—this crust is where the magic happens. If you’re using horseradish or Worcestershire, mix it into the paste beforehand.

Step 4: Preheat and Roast

Preheat your oven to 450°F (230°C). Place the roast, bone-side down, on a rack in a roasting pan. Roast at this high temperature for 20 minutes to create a crust.

Step 5: Lower Temperature and Continue Cooking

After the initial 20 minutes, reduce the oven temperature to 325°F (160°C). Continue roasting until the internal temperature reaches your desired doneness: 120°F for rare, 130°F for medium rare, 140°F for medium. Use a meat thermometer to be precise.

Step 6: Rest the Meat

Remove the roast from the oven and tent it loosely with foil. Let it rest for at least 20-30 minutes. This step is crucial—resting allows the juices to redistribute, making the meat incredibly tender.

Step 7: Carve and Serve

Using a sharp carving knife, slice between the bones or into thick slabs depending on your serving style. Serve with your favorite sides, au jus, or a creamy horseradish sauce for extra indulgence.

How Long to Prepare the Herb Crusted Prime Rib Roast

Preparation Time: Allow about 20 to 30 minutes to prepare the herb crust and coat the roast. However, you’ll need to bring the meat to room temperature before cooking, which takes about 2 hours. This step is non-negotiable for even roasting and best texture.

Cooking Time: The roasting itself takes roughly 1.5 to 2.5 hours depending on the size of the roast and desired doneness. A 6-pound roast cooked to medium-rare typically takes about 2 hours at 325°F after the initial high-heat sear. Don’t forget to add another 20–30 minutes for resting post-cooking.

Watch Out for These Mistakes While Cooking

• Skipping the rest time: Cutting too soon lets the juices run out.
• Overcooking: Use a thermometer; prime rib continues to cook slightly while resting.
• Undersalting: Be generous with salt to enhance the beef’s natural flavor.
• Using cold meat: This leads to uneven cooking.
• Too much crust charring: If the crust starts to burn, loosely tent with foil during the roast.
