There is nothing quite like the smell of a prime rib roast cooking in the oven. The rich aroma of garlic and fresh herbs fills your entire home, making everyone hungry long before dinner is ready. This roast is the ultimate centerpiece for any special meal. It has a beautiful, dark crust on the outside and a tender, juicy pink center. When you slice into it, the garlic herb butter melts over the warm meat, creating a savory sauce that is simply delicious. It looks fancy, but it is actually very easy to prepare with just a few simple steps.
Why Make This Prime Rib Roast With Garlic Herb Butter
Making a prime rib roast is one of the best ways to celebrate a holiday or a big family gathering. This recipe uses a garlic herb butter that creates an incredible flavor profile. The butter helps the salt and herbs stick to the meat, forming a delicious crust. Unlike other cuts of beef, prime rib is naturally marbled with fat, which means it stays moist and flavorful as it roasts. You do not need complicated tools or hard-to-find ingredients to make this taste like it came from a high-end restaurant. It is a reliable dish that always impresses your guests with its rich taste and melt-in-your-mouth texture.
How to Make Prime Rib Roast With Garlic Herb Butter
The secret to a great prime rib is starting with room-temperature meat. You simply mix softened butter with minced garlic and fresh herbs like rosemary and thyme. After patting the meat dry, you rub this flavorful butter all over the roast. You start the oven at a high temperature to sear the outside and lock in the juices. Then, you lower the heat to finish cooking the meat slowly. This two-step roasting method gives you that perfect golden-brown exterior while keeping the inside tender. Finally, let the meat rest before carving so all those tasty juices stay inside the beef.
Ingredients
- 5 to 6 pound beef prime rib roast (bone-in or boneless)
- 1/2 cup unsalted butter, softened to room temperature
- 6 cloves garlic, minced very fine
- 1 tablespoon fresh rosemary, chopped
- 1 tablespoon fresh thyme, chopped
- 1 tablespoon kosher salt
- 1 teaspoon coarse black pepper
- 2 tablespoons olive oil
Directions
- Remove the roast from the refrigerator about 2 hours before cooking. This allows the meat to reach room temperature, ensuring it cooks evenly.
- Preheat your oven to 450°F (230°C).
- In a small bowl, combine the softened butter, minced garlic, rosemary, thyme, salt, and black pepper. Mix well until it forms a smooth paste.
- Pat the roast dry with paper towels. Rub the olive oil all over the meat.
- Spread the garlic herb butter mixture generously over the entire roast, covering the top and sides.
- Place the roast in a roasting pan with the fat side facing up. If using a bone-in roast, the bones will act as a natural roasting rack.
- Place the pan in the preheated oven and roast for 15 minutes at 450°F. This high heat creates a beautiful crust.
- Reduce the oven temperature to 325°F (165°C). Continue roasting until a meat thermometer reaches your desired doneness (about 115-120°F for medium-rare). This usually takes about 13 to 15 minutes per pound.
- Remove the roast from the oven and transfer it to a cutting board.
- Cover the meat loosely with foil and let it rest for at least 20 to 30 minutes. This step is vital for a juicy roast.
- Slice the roast against the grain and serve warm with the pan juices.

How to Serve Prime Rib Roast With Garlic Herb Butter
This roast is a star on its own, but it pairs perfectly with classic sides. Serve thick slices of the beef alongside creamy mashed potatoes or roasted root vegetables like carrots and parsnips. A fresh green salad with a light vinaigrette helps balance the richness of the meat. You can also serve it with a side of prepared horseradish or a simple beef au jus made from the drippings in the roasting pan. For a special touch, offer warm dinner rolls to soak up every bit of the garlic butter and beef juices.
How to Store Prime Rib Roast With Garlic Herb Butter
If you have leftovers, they are just as delicious the next day. Wrap the cooled meat tightly in plastic wrap or aluminum foil and store it in an airtight container. It will stay fresh in the refrigerator for up to 4 days. If you want to keep it longer, you can freeze the roast for up to 3 months. To reheat, place slices in a baking dish with a little beef broth, cover with foil, and warm in a 300°F oven. This method prevents the meat from drying out and keeps it tender.
Expert Tips for Perfect Prime Rib Roast With Garlic Herb Butter
Always use a meat thermometer to check for doneness. Relying on time alone can be tricky because every oven and every piece of meat is different. Make sure to insert the thermometer into the thickest part of the meat, away from the bone. Another tip is to salt the meat the night before and leave it uncovered in the fridge; this acts like a dry brine and makes the meat even more flavorful. Finally, never skip the resting period. If you cut the meat too soon, all the juices will run out onto the board, leaving you with dry beef.
Delicious Variations
You can easily change the flavor of this roast by swapping the herbs. Try using fresh sage or oregano for a different earthy taste. If you like a bit of heat, add a teaspoon of crushed red pepper flakes to the butter mixture. For a smoky flavor, mix in a tablespoon of smoked paprika. You can also add a tablespoon of Worcestershire sauce to the butter for an extra punch of umami. If you prefer a sweeter crust, a small amount of brown sugar mixed with the herbs can create a lovely caramelized exterior.
Frequently Asked Questions
1. What temperature should I pull the roast out for medium-rare?
For a perfect medium-rare, take the roast out of the oven when it reaches 115°F to 120°F. The temperature will rise about 5 to 10 degrees while it rests.
2. Should I use a bone-in or boneless roast?
Both work well! Bone-in roasts often have more flavor and the bones act as a rack. Boneless roasts are much easier to slice and cook a bit faster.
3. Can I use dried herbs instead of fresh?
Yes, you can. Use about one-third the amount of dried herbs since they are more concentrated than fresh ones.

4. Why do I need to let the meat sit at room temperature before cooking?
This ensures the beef cooks evenly from the edges to the center. If it is cold, the outside might overcook before the middle is ready.
5. What if I don’t have a roasting pan?
A large cast-iron skillet or a sturdy 9×13 baking dish will work fine. Just make sure it can handle the high heat.
6. How do I make the “au jus” from the pan?
After removing the roast, place the pan on the stove over medium heat. Add a cup of beef broth, scrape the brown bits from the bottom, and simmer until slightly reduced.
7. Do I need to tie the roast with string?
If you are using a boneless roast, tying it with kitchen twine helps it keep a round shape so it cooks evenly.
8. Is it okay to use salted butter?
Yes, but if you use salted butter, reduce the amount of extra salt you add to the rub so it does not become too salty.
9. Can I cook this in a slow cooker?
While you can, you will miss out on the crispy, buttery crust that the oven provides. Oven roasting is the best method for this specific cut.
10. How much prime rib should I buy per person?
A good rule of thumb is to plan for about 1 pound per person for bone-in roasts, or half a pound per person for boneless roasts.
