Ingredients
Get ready to create an unforgettable Prime Rib Roast experience with these simple, high-quality ingredients.
For the Compound Butter:
- 8 tablespoons unsalted butter, room temperature (1/2 cup or 1 stick)
- 2 teaspoons chili powder, mild
- 1 teaspoon ground cumin
- 1 tablespoon fresh thyme, chopped
- 1 tablespoon fresh rosemary, chopped
- 3 cloves garlic, minced
- 1 teaspoon salt, to taste
- 1 teaspoon black pepper, to taste
For the Prime Rib Roast:
- 5 pounds bone-in Prime Rib Roast (standing rib roast)
- 2 medium onions, quartered
- 5 cloves garlic, peeled
- 4 sprigs fresh thyme
- 2 sprigs fresh rosemary
For the Red Wine Gravy:
- 1 cup dry red wine
- 1 cup low-sodium beef broth
- 1 tablespoon cornstarch
- 2 tablespoons water
Notes & Substitutions for Perfect Prime Rib
- Choose bone-in: The bone adds insulation, which helps the meat cook more evenly and enhances the overall flavor and juiciness of the beef roast.
- Select Prime/Choice grade: Look for good marbling (flecks of fat) throughout the meat; this ensures tenderness and exceptional flavor. To ensure you select the best quality beef for your roast, understanding the official standards for USDA beef grades and marbling is highly beneficial.
- Room temperature is key: Allowing your prime rib to sit out before cooking ensures more even cooking throughout the roast.
- Pat roast very dry: This essential step helps create that beautiful, crispy, flavorful crust. Don’t skip it!
- Season generously: A generous layer of seasoning builds deep, complex flavors.
- Tie the roast (optional): Ask your butcher to tie the roast for you; it makes carving much easier after cooking.
- Serving size guide: Plan on about 1 pound per bone-in person, ensuring generous servings and potential leftovers.
- Herb alternatives: Feel free to swap in fresh sage, oregano, or savory for a different aromatic profile.
- Wine substitute: If you prefer not to use wine, simply use an additional cup of beef broth for the gravy.
Equipment
Gather these tools to make your cooking experience smooth and easy. You’ll need a large cast iron skillet or a sturdy roasting pan that comfortably fits your Prime Rib Roast. An instant-read meat thermometer is essential for perfect doneness. Have a sharp carving knife and a spacious cutting board ready for slicing. Don’t forget aluminum foil for resting the roast. A small bowl and whisk are perfect for the gravy, and a gravy boat is optional for serving.
Instructions
Creating a showstopping Prime Rib Roast is simpler than you think. Follow these steps for an incredibly juicy and flavorful meal.
Preparing the Roast
Remove your Prime Rib Roast from all its packaging. Let it sit out at room temperature for one to two hours. This step helps ensure the roast cooks evenly. Make sure your roast is fully thawed; never cook a frozen roast. Using paper towels, pat the roast completely dry on all sides. This crucial step promotes a beautiful, crispy crust.

Instructions
- Remove roast from packaging, pat it dry with paper towels, and let it sit at room temperature for 1-2 hours to thaw completely.
- Preheat oven to 450°F for at least 30 minutes while the prime rib comes to room temperature.
- In a bowl, combine butter with chili powder, cumin, thyme, rosemary, minced garlic, salt, and pepper.
- Spread the compound butter mixture evenly over the entire prime rib roast.
- Place quartered onions, peeled garlic, thyme, and rosemary in a large skillet or roasting pan, then place the buttered roast on top.
- Cook the roast at 450°F for 15 minutes, then reduce the oven temperature to 325°F and continue cooking until a meat thermometer reads 120°F (approximately 15 minutes per pound).
- Once the roast reaches 120°F, remove it from the oven, transfer to a cutting board, cover with foil, and let rest for 20 minutes to reach a final temperature of 130°F for medium-rare.
- Slice the rested prime rib and serve with gravy over mashed potatoes.
Gravy
- While the roast rests, place the skillet with onions, garlic, and herbs over medium-high heat; add red wine and beef broth, bring to a boil, then simmer for about 5 minutes until reduced.
- Mix cornstarch with water and whisk into the simmering sauce; cook for a few more minutes until the gravy thickens to your desired consistency.
- Strain the thickened gravy into a bowl, then pour it into a gravy boat.
Notes
Making the Compound Butter
Preheat your oven to 450°F (232°C) for at least 30 minutes while the prime rib comes to room temperature. In a small bowl, combine the softened butter with chili powder, ground cumin, fresh chopped thyme, fresh chopped rosemary, minced garlic, salt, and pepper. Mix these ingredients until they are well combined. Using a spatula or your hands, spread this flavorful compound butter mixture evenly over the entire surface of the Prime Rib Roast.
Roasting the Prime Rib
Arrange the quartered onions, peeled garlic cloves, and fresh thyme and rosemary sprigs in a large cast iron skillet or roasting pan. These aromatics will infuse the roast with extra flavor and create a bed for the meat. Carefully place the prepared Prime Rib Roast on top of the onions and herbs, bone-side down, in the skillet. This positioning helps the roast cook evenly and prevents it from drying out. Roast the prime rib for an initial 15 minutes at the high temperature of 450°F. After 15 minutes, reduce the oven temperature to 325°F (163°C). Continue roasting the prime rib until an instant-read meat thermometer inserted into the thickest part of the meat (avoiding the bone) reads 120°F (49°C) for medium-rare, or your desired internal temperature. As a general guide, estimate about 15 minutes of cooking time per pound of prime rib at the lower temperature.
Resting and Carving
Once your meat thermometer reaches the target temperature, remove the Prime Rib Roast from the oven. Transfer it immediately to a clean cutting board. Tent the roast loosely with aluminum foil. Let the prime rib rest undisturbed for 20 minutes. This resting period is critical; the internal temperature will continue to rise (this is called carryover cooking), and the juices will redistribute throughout the meat, ensuring a tender and incredibly juicy roast. After resting, carefully carve the prime rib into thick slices against the grain. Serving the slices against the grain ensures maximum tenderness.
Crafting the Red Wine Gravy
While the roast is resting, place the roasting pan or skillet containing the drippings, onions, garlic, and herbs over medium-high heat on your stovetop. Pour in the dry red wine and low-sodium beef broth. Bring the mixture to a boil, then reduce the heat and let it simmer for about 5 minutes. The sauce should reduce slightly and become more concentrated. In a small bowl, whisk together the cornstarch and water to create a smooth slurry. Slowly stir this cornstarch slurry into the simmering liquid in the skillet. Continue to whisk gently and cook for a few more minutes until the gravy thickens to your desired consistency. If you prefer a thicker gravy, you can add a bit more cornstarch slurry. For a silky-smooth gravy, strain the mixture through a fine-mesh sieve into a clean bowl, discarding the solids. Pour your rich red wine gravy into a gravy boat and serve it warm alongside your carved Prime Rib Roast.

Common Mistakes to Avoid
- Cooking a cold roast directly from the fridge. Always allow it to come to room temperature first.
- Skipping the crucial resting period. This leads to dry meat as juices escape when carved.
- Not using a meat thermometer for accuracy. Guessing leads to over or undercooked results.
- Overcooking and drying out the meat. This is the biggest mistake you can make with a beautiful prime rib.
Serving Suggestions & Variations
Enhance your Prime Rib Roast experience with perfect pairings and creative twists.
- Classic Sides: Serve alongside creamy mashed potatoes, tender roasted asparagus, or decadent creamed spinach for a complete meal.
- Bread: Offer crusty bread or warm dinner rolls; they’re perfect for soaking up every last drop of the rich gravy.
- Wine Pairing: Complement your impressive beef roast with a robust Cabernet Sauvignon or a smooth Merlot.
- Herb Variations: Experiment with different compound butter flavors like a bright lemon-herb butter or a smoky paprika-garlic blend.
- Spice Blends: For an adventurous twist, try a horseradish crust or a bold Cajun seasoning rub on your prime rib before roasting.
Storage & Reheating
Proper storage and reheating ensure your delicious Prime Rib Roast leftovers remain just as enjoyable. Store any leftover prime rib slices in an airtight container in the refrigerator for up to 4 days. If you have a larger amount, you can freeze individual slices wrapped tightly in plastic wrap and then aluminum foil for up to 3 months. To reheat, gently warm slices in the oven at a low temperature (around 250°F) with a splash of beef broth, covered, until just heated through. You can also reheat gently on the stovetop with a little gravy or broth. Avoid using the microwave, as it can dry out the meat and make it tough.
