- 4 pounds boneless prime rib roast: The star of the dish, providing tender, juicy, and flavorful beef.
- ¼ cup unsalted butter (room temperature): Adds creamy richness and helps the garlic and herbs adhere to the roast.
- 5 cloves garlic (minced): Infuses every bite with a fragrant, savory depth.
- 1 tablespoon kosher salt: Enhances the natural flavors and helps form a crust.
- 2 teaspoons olive oil: Brings a subtle fruitiness and aids in browning the roast.
- 1 teaspoon dried thyme: Lends an earthy, herbal note that pairs beautifully with beef.
- 1 teaspoon dried rosemary: Offers piney, aromatic undertones to complement the garlic butter.
- 1 teaspoon ground black pepper: Adds a touch of heat and balances the richness of the butter.
How to Make Garlic Butter Prime Rib Recipe
Step 1: Bring the Rib Roast to Room Temperature
Start by placing your prime rib roast in a roasting pan and letting it sit out for about 4 hours until it reaches room temperature. This step is crucial for even cooking and ensures the meat stays juicy and tender all the way through. Trust me, patience here makes a big difference in the final texture.
Step 2: Preheat Your Oven
Set your oven to 400 degrees Fahrenheit. This high heat at the beginning will develop a gorgeous crust on the outside of the roast, locking in all those fantastic juices and flavors as it bakes.
Step 3: Prepare the Garlic Butter Mixture
In a small bowl, combine the softened unsalted butter with minced garlic, kosher salt, olive oil, dried thyme, rosemary, and black pepper. Mix thoroughly until everything is well incorporated. This flavorful butter paste is the secret weapon that transforms an ordinary roast into a divine experience.
Step 4: Coat the Roast
Generously spread the garlic butter mixture all over the prime rib’s surface. Cover every inch with those aromatic flavors because this coating will create that stunning crust and rich taste we all adore.
Step 5: Initial Roasting
Place the roast in the oven and cook it for 25 minutes at 400°F. This step is vital to forming the initial sear and caramelization, giving you that tasty exterior crunch everyone craves.
Step 6: Lower the Heat and Cook Slowly
Reduce the oven temperature to 225 degrees Fahrenheit. Cover the roast loosely with foil and continue cooking for another 1 to 1½ hours. Check the internal temperature around the 45-minute mark to avoid overcooking. This slow roasting ensures a beautifully even doneness from edge to center.
Step 7: Remove and Rest
Take the roast out of the oven once it reaches your desired internal temperature (aim for about 130°F for medium-rare). Cover it with foil and let it rest for at least 20 minutes. Resting allows the juices to redistribute throughout the meat, making each slice succulent and flavorful.
How to Serve Garlic Butter Prime Rib Recipe

Garnishes
To enhance the Garlic Butter Prime Rib Recipe’s already incredible presentation, sprinkle freshly chopped parsley or thyme just before serving. These herbs add a pop of green that brightens the plate, along with a fresh herbal aroma that elevates the dish’s rustic charm.
Side Dishes
This prime rib pairs beautifully with a variety of classic sides. Creamy mashed potatoes balance the rich meat, while roasted vegetables add color and texture. A crisp green salad or Yorkshire pudding also make wonderful companions, bringing fresh or fluffy contrasts to the plate.
Creative Ways to Present
For a fun twist, arrange thin slices of the garlic butter prime rib on a wooden board paired with horseradish cream and crusty bread. Or, serve individual portions stacked with grilled asparagus spears and a drizzle of pan juices for an elegant look that’s sure to impress your guests.
Make Ahead and Storage
Storing Leftovers
Once cooled, wrap your leftover prime rib tightly in foil or place it in an airtight container. Store it in the refrigerator for up to 3 days. Proper wrapping ensures the meat stays moist and flavorful for easy reheating.
Freezing
If you want to keep leftovers longer, slice the prime rib and freeze in freezer-safe bags. Be sure to remove as much air as possible to prevent freezer burn. Frozen prime rib will stay delicious for up to 3 months and can be thawed overnight in the refrigerator before warming up.
Reheating
The best way to reheat leftover prime rib is gently in the oven at 250°F, covered with foil to retain moisture. Warm it until just heated through, usually around 15 to 20 minutes depending on thickness. Avoid microwave reheating to keep the texture tender and juicy.
FAQs
Can I use bone-in prime rib for this recipe?
Absolutely! Bone-in will add extra flavor and help insulate the meat during cooking, but you may need to adjust the cooking time slightly. Just keep an eye on the internal temperature for perfect doneness.
How do I know when the prime rib is cooked to my liking?
Use a meat thermometer for the best results. About 130°F for medium-rare, 140°F for medium, and 150°F for medium-well. Remember to factor in carryover cooking during resting time.
Can I prepare the garlic butter mixture in advance?
Yes, you can mix the garlic butter up to a day ahead and keep it refrigerated. Bring it to room temperature before spreading on the roast to make it easier to apply evenly.
What if I don’t have dried herbs on hand?
Fresh herbs can be used instead, but use about three times the amount since dried herbs are more concentrated. Fresh rosemary and thyme add a lovely bright flavor if you have them.
Is it necessary to bring the roast to room temperature?
While not absolutely required, allowing the roast to come to room temperature ensures even cooking throughout and helps achieve that perfect juicy texture without an overcooked exterior.
