Traeger Prime Rib Roast Recipe - How to Smoke Perfectly

Ever had one of those days where you just need to impress the socks off your guests? Yeah, me too. Last Thanksgiving, I decided to throw caution to the wind and make a smoked prime rib on my Traeger. Yep, you heard that right—prime rib, the crown jewel of meats. I was equal parts excited and terrified. What if I ruined it? What if I over-smoked it and it turned into a hunk of meat jerky? But folks, let me tell you, it turned out so mouthwateringly good that I still daydream about it. And now, I'm sharing the love with you.

How to Make Smoked Prime Rib on a Traeger: The Step-by-Step Breakdown

Alright, let's get down to business. If you’ve never done this before, don’t sweat it. I’ve got your back with a quick and easy breakdown.

Pick Your Rib: Start by choosing the right cut of meat. Go for a bone-in rib roast if you can—it’s got that extra flavor. The size? Depends on how many mouths you’re feeding, but generally, a 4-bone roast will serve around 8 people.
Season Like You Mean It: This ain’t the time to be shy with your seasonings. I like to go heavy with kosher salt, cracked black pepper, garlic powder, and a touch of smoked paprika for that extra oomph. Rub it in like you're giving it a deep-tissue massage. Let the rib sit for at least an hour—overnight if you can.
Fire Up the Traeger: Preheat your Traeger to 225°F. This is where the magic happens. You want low and slow, so the meat gets that perfect smoky infusion.
Smoke It Up: Place the prime rib directly on the grill grates. Close the lid and let it cook for about 3-4 hours, or until the internal temperature hits 120°F. Remember, this is the prime time to crack open a cold one and relax—just keep an eye on that thermometer.
The Sear: Once you hit that sweet internal temp, crank the Traeger up to 450°F. Sear the prime rib for about 15 minutes, until you get that crispy, drool-worthy crust.
Rest and Slice: Take the rib off the grill and let it rest for a good 20-30 minutes. I know, the wait is agonizing, but trust me, it’s worth it. Then, slice it up, and watch as everyone’s eyes widen with anticipation.

What Wood/Pellets to Use for This Recipe?

Now, let’s talk wood—because this isn’t just about throwing any ol’ wood on the fire. For prime rib, I’m all about a mix of hickory and oak. Hickory gives it that rich, bacon-y flavor, while oak keeps things balanced and smooth. It’s like the Batman and Robin of wood pairings.

Some folks swear by mesquite, but I find it can be a bit too aggressive for prime rib. This is a premium cut, after all, so you want to complement the meat’s natural flavor, not overshadow it. If you’re feeling adventurous, you can toss in some cherry wood for a hint of sweetness. But honestly, hickory and oak are where it’s at.

Additional Tips: Because You Deserve Perfection

Monitor the Temp Religiously: Don’t be that person who leaves the grill unattended for hours. Get yourself a good meat thermometer, and check the internal temp regularly. When it hits 120°F, that’s your cue for the sear.
Don’t Forget the Resting Period: I know it’s tempting to dive right in, but letting the meat rest is crucial. It allows the juices to redistribute, making each bite tender and juicy. Trust me, it’s worth the wait.
Basting Optional, but Recommended: Some folks like to baste the prime rib with a bit of butter or beef broth halfway through the cook. It’s not essential, but it adds an extra layer of richness that’ll have your guests licking their plates.

What to Serve with Smoked Prime Rib?

Alright, you’ve nailed the prime rib—now what do you serve it with? You need sides that can hold their own without stealing the show.

Creamy Garlic Mashed Potatoes: These are a must. The creamy, buttery goodness pairs perfectly with the smoky, savory rib.
Roasted Brussels Sprouts with Bacon: The smoky flavor of the bacon ties in beautifully with the prime rib. Plus, it’s a nice way to pretend you’re eating healthy.
Horseradish Sauce: A classic pairing. The sharpness of the horseradish cuts through the richness of the meat.
A Big, Bold Red Wine: Think Cabernet Sauvignon or Malbec. You want something that can stand up to the flavors on your plate.

Leftovers: Because the Feast Should Never End

Now, what if—by some miracle—you’ve got leftovers? First of all, congrats on your self-restraint. Second, there’s so much you can do with leftover prime rib.

Prime Rib Sandwiches: Thinly slice the meat, slap it on some crusty bread, and add a dollop of horseradish sauce. Perfection.
Beef Stroganoff: Take your leftover prime rib, toss it into a creamy mushroom sauce, and serve it over egg noodles. It’s a decadent twist on a classic.
Philly Cheesesteak: Substitute the usual ribeye for your prime rib, throw in some grilled onions and peppers, and top it with melty provolone. You won’t regret it.
Tacos: Yes, tacos. Warm up the prime rib, add some pico de gallo, a squeeze of lime, and you’ve got yourself a gourmet taco experience.

Overall, making smoked prime rib on a Traeger is one of those culinary experiences that’s equal parts challenging and rewarding. The first time might feel like a leap of faith, but when you slice into that perfectly cooked, smoky goodness, you’ll realize it was all worth it. So go on, get that Traeger fired up, and give it a try. And when you’re biting into that first, juicy slice, remember this—great things come to those who smoke.

Ingredients

For the Prime Rib:

1 4-bone Prime Rib Roast (around 8-10 pounds)
2 tablespoons kosher salt
2 tablespoons freshly cracked black pepper
1 tablespoon garlic powder
1 tablespoon onion powder
1 tablespoon smoked paprika
1 tablespoon fresh rosemary finely chopped
1 tablespoon fresh thyme finely chopped
2 cloves garlic minced
¼ cup olive oil

For the Homemade Horseradish Sauce:

½ cup sour cream
2 tablespoons prepared horseradish or freshly grated if you're ambitious
1 teaspoon Dijon mustard
1 teaspoon white vinegar
Salt and pepper to taste

For the Smoked Butter Baste:

½ cup unsalted butter
2 cloves garlic minced
1 tablespoon fresh rosemary finely chopped
1 tablespoon fresh thyme finely chopped
Zest of 1 lemon

Instructions

Seasoning the Prime Rib (Day Before)

In a large mixing bowl, combine kosher salt, black pepper, garlic powder, onion powder, smoked paprika, rosemary, thyme, minced garlic, and olive oil. Mix until it forms a paste.
Pat the prime rib roast dry with paper towels. Rub the seasoning paste all over the roast, making sure to coat it evenly. For best results, let it marinate in the fridge for at least 24 hours. This allows the flavors to really penetrate the meat. Cover it loosely with plastic wrap.

Smoking the Prime Rib

On the day of cooking, take the prime rib out of the fridge and let it come to room temperature for about an hour. Preheat your Traeger to 225°F using a mix of hickory and oak pellets.
Place the seasoned prime rib directly on the grill grates, bone side down. Insert the meat thermometer into the thickest part of the meat, avoiding bone.
Close the lid and let the Traeger do its magic. Smoke the prime rib for about 3-4 hours, or until the internal temperature reaches 120°F for medium-rare. This low and slow method ensures a tender and juicy roast.

Searing and Resting

While the prime rib is smoking, melt the butter in a small saucepan over low heat. Add the minced garlic, rosemary, thyme, and lemon zest. Stir occasionally, letting the flavors meld together. Set aside.
Once the prime rib reaches 120°F, increase the Traeger’s temperature to 450°F. Brush the prime rib generously with the smoked butter baste, and let it sear for about 15 minutes, or until the crust is deep golden-brown and crispy.
Remove the prime rib from the grill and tent it loosely with aluminum foil. Let it rest for 20-30 minutes. This resting period is crucial—it allows the juices to redistribute, making every bite tender and flavorful.

Preparing the Horseradish Sauce

While the prime rib is resting, combine the sour cream, horseradish, Dijon mustard, and white vinegar in a mixing bowl. Stir until well combined. Season with salt and pepper to taste. Let it chill in the fridge until ready to serve.

Serving and Enjoying

After the prime rib has rested, transfer it to a cutting board. Use a sharp carving knife to slice it into thick, juicy slices. Serve immediately with a side of the homemade horseradish sauce.
