Smoked garlic butter prime rib is the best version of smoked prime rib on the internet. Slathered in herb-infused compound butter and slow-smoked to perfection, this prime rib is sure to be the crowning glory of your holiday table.
Garlic Butter Prime Rib
I am all about slow-smoked hunks of beef, and there is nothing more indulgent or delicious than a smoked prime cut of a beef rib roast. I’ve been smoking prime rib for years, but this method quickly shot up to the top of my favorite recipes. The entire roast is enrobed in seasoned garlic butter to infuse the roast with flavor and slowly baste the meat’s exterior during the smoking process.
Another bonus from this smoked garlic butter crust is the melted browned butter drippings. I smoke my garlic butter prime rib on a rack above a baking sheet. That way, as the meat smokes and the butter slowly melts, it collects underneath the roast and bubbles and browns. When the roast is finished, I strain that gorgeous butter, season it with a little salt, and use that as a finishing sauce to drizzle over the sliced prime rib. It’s absolutely indulgent.
Ingredients for Garlic Butter Prime Rib
The base of this recipe is extremely simple. All you need to season the roast is high-quality salt and black pepper (Adjust the 1 Tablespoon amounts here as needed to cover the entire roast).
- 8-10 pound bone-in prime rib roast
- 1 Tablespoon coarse ground salt
- 1 Tablespoon black pepper
For the garlic herb butter, you’ll need the following ingredients:
- 16 ounces softened butter
- 8 cloves minced garlic
- 2 sprigs of finely minced rosemary
- 2 sprigs of finely minced thyme
- 2 teaspoons salt
- 2 teaspoons black pepper
The flavors in the seasoned butter are inspired by a resting butter I use on grilled steaks. The idea is to enhance the beef’s natural flavor without overpowering those subtle earthy notes in the meat. The butter has fresh garlic, fresh herbs, and salt and pepper. It’s simple but absolutely incredible. The garlic and herbs smoke on the outside edges of the prime rib roast and make the most delicious crust ever!
How to Make Garlic Butter Prime Rib
Let’s get going on making this amazing roast! The process is fairly straightforward and should result in an incredible, unforgettable meal. Here’s how to make garlic butter prime rib:
- Preheat. Fire up your favorite smoker and allow it to fully preheat to 225 degrees F with oak or hickory wood.
- Prep. Trim the top of the roast down to 1/4 inch thick. Season the roast on all sides with salt and pepper.
- Slather in garlic butter. Make the garlic butter in a small bowl, and then slather the roast on all sides with the butter.
- Smoke. Place the buttered roast on a flat baking rack above a rimmed baking sheet on the smoker. Smoke until the prime rib reaches 120 degrees F for Rare doneness, 125 degrees F for Medium-Rare, or 130 degrees F for Medium doneness.
- Rest. Remove the prime rib from the smoker and rest for 20 minutes. Increase the temperature of the smoker to 400 degrees F. Strain the butter and drippings from the baking sheet and set aside.
- Sear. Once the grill reaches 400 degrees F, place the prime rib directly on the grill grates and sear the meat until it reaches your preferred final doneness (130 degrees F for Rare, 135 degrees F for Medium-Rare, or 140 degrees F for Medium).
- Enjoy. Remove the garlic butter prime rib from the smoker and rest for around 15 minutes. Drizzle with the reserved drippings before slicing and serving.
How Long to Smoke Garlic Butter Prime Rib
Plan approximately 35 minutes per pound at 225 degrees F for smoking a rare roast. If you like your prime rib closer to medium, plan on 40 minutes per pound. Don’t forget to allow at least 30 minutes of rest time and another 15 minutes or so for the high-heat sear before serving when factoring in the total amount of time it will take to smoke this garlic butter prime rib.
Of course, the most essential part of smoking a perfectly pink prime rib roast is cooking it to the correct internal temperature. For that, I recommend getting an internal thermometer that you can use to track your prime rib during the entire cooking process.

Ingredients
- 1 8-10 pound bone-in prime rib roast
- coarse salt and pepper
Garlic Herb Butter
- 16 ounces softened butter
- 8 cloves garlic minced
- 2 sprigs rosemary finely minced
- 2 sprigs thyme finely minced
- 2 teaspoons salt
- 2 teaspoons black pepper
Instructions
- Preheat. Preheat your smoker to 225 degrees F for indirect cooking. I recommend oak or hickory for this recipe.
- Prep the prime rib. While the grill is warming up, prepare your roast. Trim any excess fat from the top of the roast down to 1/4 inch thick. Season on all sides with an even sprinkling of salt and pepper.
- Slather in garlic butter. In a small bowl combine the softened butter, garlic, herbs, salt, and pepper. Slather the entire roast with the garlic butter.
- Smoke. Place the roast on a flat rack elevated above a baking sheet on the smoker. Close the lid, and smoke the roast until the internal temperature reaches 120 degrees F for Rare or 128 degrees F for Medium. For a rare, bone-in roast, plan on 35 minutes per pound of prime rib.
- Rest. Remove the roast to a cutting board and allow to rest for 20 minutes. Strain the butter and drippings from the baking sheet into a separate bowl and set aside. While the roast is resting, increase the temperature of your grill to 400 degrees F.
- Sear the roast. Once the grill is up to temperature, return the roast to the grill and sear until you reach your desired internal temperature. Pull the roast off at 130 degrees F for rare, 135 for medium rare, or 140 for medium. This process should go quickly, so keep a close eye on your temperature.
- Rest, slice, and serve. Remove the prime rib to the cutting board and let the meat rest for at least 15 minutes before slicing and serving. Drizzle the reserved butter and drippings over the roast for an extra decadent finish.

Looks delicious. Any suggestions for developing a jus?
How can I make this on gas grill? Which cut of prime rib do you recomnend?I haven’t made it yet so I cant provide a review. But all the recipes I have tried had been terrific! And I think this one will be as well!
You can use these techniques to help impart some smoke flavor, but the cooking process is the same on a gas grill or in an oven. Follow as written!
Is searing at 120 degrees necessary or can I smoke until135 degrees?
That will work just fine!
I am planning on doing this for a prime rib for Christmas. bis the butter salted or unsalted
I use salted butter!
and you use Salt?
Love it I finally got to try it out in my smoker and had to take it out Early but very good
My 8.5 lb. roast took WAY less time to cook on the pellet smoker. Started at 225, had to drop temp to 200 2 hours in. We like rare, so I pulled at 120 (it got there in only 22 mins/lb.). Of course nothing else was ready so I wound up resting it for an hour, then seared for 10 mins at 450. Final temp was 130 and it was a Christmas miracle because it was perfect! Can’t emphasize enough the unpredictability of smoking large cuts of meat, so be ready for anything and trust your instincts!
TRULY appreciate this comment! This seems to always be the case for as well… Seemingly always catches me unawares. Prepping everything else NOW thanks to your “heads up” reminder
We made this for our Christmas dinner yesterday 12/26/22. I actually smoked two a 5lb. and a almost 10 lb. That way I was able to have the small one for those who like there’s a little more done then us true carnivores. It was amazing. Thankful we had enough, we get leftovers tonight. I go no where else to find my perfect smoking recipes. I cannot thank you enough for your website and your generosity of giving us the recipes for the products you sale. I need to print them off. I am scared I will come to look for one I love and it will be gone. Merry Christmas to your family and staff and Happy New Year!
I made it for Christmas dinner, it was awesome! Thank you!
This. Was. The. Best. Directions were spot on. I did the HGH Grill Squad masterclass and it helped me confidently request the meat I wanted from the butcher. Smoking adds that extra kiss of flavor. I used Lumberjack oak, hickory, and cherry blend. Susie always does an amazing job with her step by steps directions and videos so I feel like I know what I’m doing. Bottom line…. my frosted meat cake was perfect. Thanks Susie and the HGH Team… even Taste Test Todd.
Use salted butter or unsalted? Wife and I are each convinced we are right. She says it’s definitely unsalted, I assumed salted butter. Can you please save our Christmas with the correct butter to use? Thanks so much in advance!!!
