I gotta tell you about the time I discovered the Green Mountain Grill and its magic powers when it comes to smoked prime rib. It was one of those sunny Sunday afternoons, you know the kind, where the weather's just right and you can almost taste the barbecue in the air. My buddy Jack had just got his hands on this grill, and boy, was he excited to show it off. Spoiler alert: he wasn’t the only one who fell in love that day.
How to Make Smoked Prime Rib on a Green Mountain Grill
First things first, you gotta get yourself a good cut of prime rib. Don’t skimp on this part. It's the star of the show, after all. I usually go for a nice, marbled 5-6 pounder, enough to feed a small army or just a few very hungry friends. Trust me, you'll want leftovers. Here’s the lowdown on how to make that perfect smoked prime rib:
- Prep the Meat: Start by letting your prime rib sit at room temperature for about an hour. You don’t want to shock the meat by throwing it on the grill while it’s still cold. Give it some love – rub it all over with olive oil, then generously season with kosher salt, black pepper, garlic powder, and rosemary.
- Preheat the Grill: Fire up your Green Mountain Grill to 225°F. This grill’s got a digital control that makes it as easy as pie to maintain the right temperature. No guesswork here, folks.
- Choose Your Wood: For this recipe, I’m a big fan of using hickory or oak pellets. They give a rich, smoky flavor that pairs perfectly with the prime rib. If you’re feeling adventurous, mix in a bit of cherry or applewood for a touch of sweetness.
- Smoke It: Place your seasoned prime rib directly on the grill grate. Insert a meat thermometer into the thickest part of the roast. Smoke until the internal temperature reaches 130°F for medium-rare, which should take about 4-5 hours. Don’t rush it – low and slow is the name of the game here.
- Rest and Sear: Once you’ve hit that magic number, take the roast off the grill and let it rest for about 20 minutes. Meanwhile, crank up the grill to 500°F. After resting, give the prime rib a quick sear on all sides for that beautiful crust.
- Slice and Serve: Carve the roast into thick, juicy slices. You’ll hear the angels sing with every cut, I promise.
What Type of Wood/Pellets to Use
Alright, let's talk pellets. As I mentioned, hickory and oak are my go-to’s for prime rib. They’re robust and add that classic barbecue flavor. If you want a bit of a sweeter note, mix in some cherry or applewood. The Green Mountain Grill handles these pellets like a champ, giving you consistent smoke and flavor every time.
Additional Tips
- Use a Meat Thermometer: Seriously, this little gadget will save you from overcooking or undercooking your precious prime rib.
- Resting is Key: Don’t skip the resting step. It lets the juices redistribute, making your meat tender and flavorful.
- Experiment with Rubs: Don’t be afraid to try different herbs and spices. Sometimes I throw in a bit of thyme or a touch of cayenne for a kick.
What to Serve with Smoked Prime Rib
Now, what’s a prime rib without some killer sides? Here’s what I like to serve:
- Garlic Mashed Potatoes: Creamy, buttery, and full of garlic goodness.
- Grilled Asparagus: Tossed in olive oil and seasoned with salt and pepper. Simple and delicious.
- Caesar Salad: Crisp romaine, parmesan cheese, and a zesty Caesar dressing. Keeps things fresh.
- Yorkshire Pudding: Because nothing soaks up those delicious meat juices like a good Yorkshire pudding.
What to Do with Leftovers
If you’re lucky enough to have leftovers, here are a few ideas:
- Prime Rib Sandwiches: Thick slices of prime rib on crusty bread with a bit of horseradish sauce. Perfection.
- Steak and Eggs: Dice up the prime rib and toss it with scrambled eggs for a hearty breakfast.
- Beef and Veggie Stir-Fry: Quick, easy, and oh-so-tasty. Just toss your leftover prime rib with some veggies and soy sauce.
Overall, smoking a prime rib on the Green Mountain Grill is a game changer. It’s one of those things that once you’ve tried it, you’ll wonder how you ever lived without it. The smoky flavor, the tender meat, the compliments from your friends and family – it’s all worth it. So go ahead, give it a shot, and let me know how it turns out. Thanks for reading, and happy grilling!

- 5-6 pound prime rib roast
- 3 tablespoons olive oil
- 2 tablespoons kosher salt
- 1 tablespoon freshly ground black pepper
- 1 tablespoon garlic powder

- 2 tablespoons fresh rosemary chopped (or 1 tablespoon dried rosemary)
- 2 tablespoons fresh thyme chopped (or 1 tablespoon dried thyme)
Instructions
Preparing the Prime Rib
- Remove the prime rib from the refrigerator and let it sit at room temperature for about 1 hour. This helps the meat cook more evenly.
- In a mixing bowl, combine kosher salt, black pepper, garlic powder, onion powder, rosemary, and thyme.
- Rub the prime rib all over with olive oil. Then, generously apply the seasoning rub to all sides of the meat, making sure to press it into the meat.
Smoking the Prime Rib
- Preheat your Green Mountain Grill to 225°F. Make sure the pellet hopper is filled with your chosen wood pellets. Hickory or oak are excellent choices for a rich, smoky flavor.
- Place the seasoned prime rib directly on the grill grate. Insert a meat thermometer into the thickest part of the roast to monitor the internal temperature.
- Smoke the prime rib until it reaches an internal temperature of 130°F for medium-rare. This typically takes about 4-5 hours, depending on the size of your roast.
Resting and Searing
- Once the prime rib reaches 130°F, remove it from the grill and cover it loosely with aluminum foil. Let it rest for 20 minutes. This allows the juices to redistribute throughout the meat.
- While the meat is resting, increase the grill temperature to 500°F.
- After the resting period, return the prime rib to the grill and sear it on all sides for about 5-10 minutes. This gives the meat a beautiful crust.
Serving and Optional Sides
- Transfer the prime rib to a cutting board and carve it into thick slices.
