Coffee herb rub, cherry pellets, and a 225°F-to-450°F reverse sear turn this Smoked Prime Rib into a mahogany-crusted, edge-to-edge medium-rare roast. The dry brine happens the night before, so the actual cook day stays mostly hands-off once the smoker's running. I build the au jus straight from the pan drippings, and the crust holds its color because the rub and wood were picked to work together, not tossed on out of habit.

How I Built My "Coffee Smoke Ring" Prime Rib Smoked Prime Rib
Coffee herb rub + cherry pellets = deep bark, not bitterness
I wanted a bark that tasted as good as it looked, so I started playing with a coffee-based rub on the pellet smoker. The coffee adds a deep, almost chocolate-like flavor and helps build that dark crust, but it can turn harsh if you push it too far. Cherry pellets ended up being the sweet spot for me: they add a gentle, slightly sweet smoke that supports the coffee and herbs instead of fighting them. The result is a thick, flavorful bark that tastes complex, not burnt or bitter.
Mustard and Worcestershire binder that actually does something
The mustard and Worcestershire aren't there just because "that's what BBQ people do." I use them because they actually solve a problem: keeping a fairly loose rub stuck to a big piece of meat through a long cook. The mustard adds just enough stickiness and acidity to help the rub cling and start breaking down the surface. The Worcestershire brings salt, umami, and a little sugar, which all help with browning. By the time the roast hits the smoker, the surface is tacky and well-seasoned, and the rub stays put instead of falling into the drip pan.
Low-and-slow smoke with reverse sear for a perfect medium-rare center
For this cut, I treat the smoker like a very flavorful low oven. I run the roast low and slow so the interior can come up to temperature gradually, which gives you that edge-to-edge medium-rare instead of a gray band around the outside. Once it's just shy of my target temp, I rest it briefly, then crank the heat for a reverse sear. That blast of high heat tightens and crisps the bark without overcooking the center you just spent hours bringing up gently. It's a little extra step, but it's the difference between "pretty good" and "this is exactly how I wanted it."
Ingredients and What Each One Does
The roast: boneless vs bone-in standing rib roast
- Boneless prime rib roast - This is what I make for bigger holiday dinners when I want easy slicing, neat leftovers, and no one fighting over bones. It cooks very evenly, which makes hitting that perfect medium-rare center a lot less stressful.
- Bone-in standing rib roast - I save this for smaller gatherings where I want that "whoa" moment when it comes to the table. The bones act like a built-in roasting rack, and I always claim one for myself later as a cook's treat.
- Kosher salt - This is the one thing I will not skip; I use it for an overnight dry brine so the roast tastes seasoned all the way through, not just on the outside. Anytime I don't plan ahead with salt, I regret it at the carving board.
- Freshly ground black pepper - I like a coarser grind so you can actually see and taste the pepper in the crust. When I make this for pepper lovers, I grind it directly onto the roast right before it hits the smoker.
Coffee herb rub breakdown
- Finely ground coffee - This is the ingredient that makes people pause mid-bite and ask what's going on in the crust. I use a medium roast espresso grind so it gives a deep, almost chocolatey flavor instead of "you're drinking a cup of coffee with your beef."
- Brown sugar - Just enough to help the crust caramelize and smooth out any sharp edges from the coffee. In my side-by-side tests, the version with a little sugar always disappeared first.
- Smoked paprika - Even though this roast lives in the smoker, I still add smoked paprika to fill in any gaps when the pellets run mild. It's my shortcut to that rich, brick-red bark that looks like it came from a legit BBQ joint.
- Dried thyme and rosemary - I rub these between my fingers as I sprinkle so they actually wake up and flavor the bark. They're my little nod to classic Sunday roast, tucked into a very smoky, modern recipe.
- Granulated garlic and onion - I lean on the granulated versions because they cling beautifully and don't scorch as quickly in the smoker. I make this for family dinners when I want every bite to taste like comfort food, just with a little more attitude.
Mustard paste and when to use it
- Yellow mustard - This is my go-to binder when I'm committed to a serious bark and don't want half my rub falling off into the drip pan. You don't taste "mustard roast" at the end; it just gives the surface that tacky, even coat so everything sticks.
- Worcestershire sauce - I swipe this on under the mustard when I want extra umami and color without mixing a full marinade. This is what I reach for on busy days when I still want the outside of the roast to taste like I fussed over it.
Garlic herb butter finish
- Unsalted butter - This is what I soften and mash with herbs and garlic, then melt over the hot crust right before slicing. I make this for any "celebration dinner at home" because it instantly makes the roast look and taste like a steakhouse splurge.
- Fresh garlic - I prefer fresh cloves here because they bloom in the warm butter and perfume the whole roast. When I'm cooking for garlic lovers, I don't hold back; this is the flavor they remember.
- Fresh parsley and thyme - I stir these in at the very end so they stay bright and green instead of turning dull. They cut through the richness just enough, and they make the platter look like something you actually planned, not just threw together.
Au jus from smoker drippings
- Beef broth - This is the quiet helper that stretches the drippings into enough sauce for the table without watering down the flavor. On weeknights or busy holidays, I grab a good boxed broth and let the smoker do the fancy work.
- Drippings from the smoker drip pan - This is the part that makes this recipe feel completely mine: I build the sauce from what the roast gives me. I make this whenever I want the au jus to taste like a smoky, concentrated version of the meat itself, not just warm broth.
- A splash of Worcestershire or soy sauce - I add this at the end when the au jus tastes good but not quite "I'd happily sip this from a mug" good. It's my fast way to deepen the flavor without cooking it down forever.
How to Smoke Prime Rib on a Pellet Smoker
1. Trim, dry brine, and tie the roast
I start by trimming off just the thick, hard outer fat that I know won't render, but I always leave a good cap so the roast self-bastes in the smoker. Once it's trimmed, I pat it very dry, season it generously with kosher salt on all sides, and tuck it on a rack in the fridge, uncovered, for an overnight dry brine so the salt has time to move inward and the surface can dry out for better browning. If I'm using a boneless roast, I tie it every couple of inches so it holds a round, even shape and cooks at the same rate from end to end. If you're still deciding which cut to buy, I break down exactly how bone-in, boneless, and standing rib roast differ in my Oven Baked Ribs guide - the same trimming and tying logic applies across most large roasts.
2. Mix the coffee rub and apply the binder
The next day, I mix the coffee rub right before I need it so the aromas are fresh and the brown sugar isn't clumping. I whisk the dry ingredients together in a bowl, then set them aside while I coat the roast lightly with Worcestershire and a thin layer of yellow mustard, treating it like I'm priming a wall before paint. The surface should feel tacky, not wet, so the rub clings in an even, generous layer instead of sliding around; I press it on with my hands rather than shaking from way above so I don't waste half of it on the cutting board.
3. Set up the pellet smoker and drip pan
Before the roast goes anywhere near heat, I get the pellet smoker completely ready so I'm not scrambling later. I fill the hopper with cherry pellets, set the temp to 225°F, and let the smoker preheat long enough to come fully up to temperature and start producing clean, steady smoke rather than thin white wisps. Under the grate where the roast will sit, I slide in a sturdy drip pan with a bit of beef broth or water in the bottom; it catches the rendered fat and smoky juices, and that's what I turn into the au jus later instead of letting it burn off on the deflector plate.
4. Smoke low-and-slow at 225°F
When the smoker is ready, I set the roast on the grates fat cap up so the melting fat runs down over the meat as it cooks. From here, I treat the smoker like a very flavorful low oven and resist the urge to keep opening the lid; I rely on a good probe thermometer and aim for a slow, steady climb toward my target pull temperature. During this stage, I'm not chasing a specific time as much as a look and an internal temp: the bark should darken and set, the roast should feel gently springy when poked, and the thermometer is my final say.
5. Rest, build the au jus, and make the herb butter
Once the roast hits just shy of my target temp, I pull it from the smoker, tent it loosely with foil, and let it rest while I deal with everything it left behind. I skim the excess fat from the drip pan, set it over gentle heat, and stir in more broth plus a splash of Worcestershire or soy until it tastes like concentrated smoked beef instead of just salty liquid. While that simmers, I mash softened butter with garlic and fresh herbs in a small bowl; that butter is my finishing move, and I keep it ready to go so it can melt over the crust while the meat is still hot. If you love a rich, glossy sauce built from the pan drippings, my Red Wine Braised Short Ribs takes that concept even further - the braising liquid reduces into something you'll want to put on everything.
6. Reverse sear at 450°F and serve
For the reverse sear, I crank the pellet smoker (or a separate grill or oven) up to 450°F and give it time to actually reach that temperature so I get a quick, intense blast of heat. The rested roast goes back in just long enough to re-crisp and deepen the bark without pushing the center past the medium-rare I worked for; this part goes fast, so I stay close. As soon as it comes off, I set it on the board, spread the garlic herb butter over the sizzling crust, give it a short final rest so the juices settle, then slice thick, rosy pieces and pass the warm smoked au jus at the table.

Instructions
Night Before - Dry Brine
- Combine all coffee herb rub ingredients in a small bowl and stir until evenly blended.
- Pat the ribeye roast dry on all sides with paper towels.
- Trim the fat cap to approximately ¼ inch thickness. Score in a diamond pattern - diagonal lines about 1 inch apart, then rotate and repeat. Do not cut into the meat.
- For a boneless roast, tie with butcher's twine every 2 inches to help it hold its shape during the cook.
- Sprinkle the coffee herb rub generously over every surface and press gently so it adheres.
- Place the roast on a wire rack set over a rimmed baking sheet and refrigerate uncovered for 8 to 24 hours. Do not skip this step - the dry surface that forms overnight is what allows the bark to develop properly.
Day Of - Prep and Smoke
- Remove the roast from the refrigerator about 1 hour before smoking and let it sit at room temperature.
- Whisk together the Dijon mustard, Worcestershire sauce, minced garlic, and rosemary in a small bowl until combined. Set the mustard paste aside.
- Set up your smoker. For a double grate smoker, place a foil-lined drip pan on the lower grate below where the roast will sit. For a single grate smoker, place a disposable aluminum roasting pan directly on the grate and set the roast on a wire rack inside the pan.
- Fill the hopper with cherry pellets. Start the smoker with the lid open. Once the flame is ignited, close the lid and preheat to 225°F for about 15 minutes.
- Brush the mustard paste in a thin, even coat over every surface of the roast.
- Spray or drizzle and dab all sides generously with beef tallow.
- Place the roast fat-side up directly on the smoker grate above the drip pan.
- Insert a wireless probe thermometer into the thickest part of the roast, making sure the tip is centered and not sitting in a fat pocket.
- Close the lid and smoke undisturbed until the internal temperature reads 125°F - approximately 35 minutes per pound. Try not to open the lid during the first 2 hours.
Rest and Prepare for Reverse Sear
- Once the roast hits 125°F, remove it from the smoker and place it on a cutting board. Rest uncovered for 30 minutes.
- Remove the drip pan from the smoker and pour the drippings and any meat bits into a medium saucepan.
- Crank the smoker to 450°F with the lid closed and let it fully preheat.
- While the smoker preheats, make the herb butter: stir together the softened butter, minced garlic, rosemary, thyme, salt, and pepper until smooth. Set aside.
Au Jus
- Set the saucepan with drippings over medium heat.
- Add the beef broth, Worcestershire sauce, garlic powder, and pepper.
- Bring to a simmer and cook for 8 to 10 minutes, stirring occasionally, until slightly reduced and the flavor has deepened.
- Taste and add salt as needed.
- Strain through a fine-mesh strainer into a serving pitcher and keep warm until serving.
Reverse Sear
- When the smoker reaches 450°F and the roast has rested 30 minutes, spray or dab all sides again with beef tallow.
- Return the roast to the smoker on indirect heat - away from the firepot with the flame grate closed.
- Close the lid and sear for 15 minutes, rotating the roast halfway through, until a deep brown crust has formed on all sides.
- Pull the roast from the smoker. Internal temperature should read 130°F for medium rare.
- Immediately spread the herb butter over the hot crust on all sides and let it melt for about 5 minutes before carving.
- If guests are not ready, tent loosely with foil and hold for up to 30 minutes.
Carve and Serve
- Slice the roast into ½-inch to ¾-inch slices against the grain.
- Serve immediately with warm au jus alongside.
My Best Tips for Getting This Right Every Time
How much prime rib per person (and how big a roast to buy)
For a boneless roast, I plan about 8-10 ounces of cooked meat per person if there are a few hearty eaters at the table, and closer to 6-8 ounces when there are lots of sides or appetizers. When I'm standing at the butcher counter doing the math, I assume I'll lose some weight to trimming and cooking, so I'd rather buy a little extra and enjoy leftovers than watch the last slices disappear too fast.
Internal temperatures and carryover cooking you can trust
I treat the thermometer as the boss and aim to pull the roast a few degrees before my "dream" number, knowing it will keep climbing while it rests. For medium-rare, I like to pull around the low 120s, tent it loosely with foil, and let carryover cooking bring it into the mid-120s to low 130s as the juices settle. The important thing is to stick the probe into the thickest part, avoiding big seams of fat or bone, so you're getting a real read on the center, not a hot spot.
When to choose cherry, oak, or blended pellets
Cherry is what I reach for when I want a gentle, slightly sweet smoke that lets the coffee rub and beef flavor stand out without turning harsh over a long cook. Oak runs a bit stronger and more straightforward; I use it when I know my guests like a more pronounced smoke profile or I'm pairing the meat with bolder sides. Blended pellets are my "don't overthink it" option on busy days - they're usually balanced enough that you get good smoke without needing to micromanage which wood is in the hopper.
How to adapt this for a bone-in standing rib roast
With a bone-in roast, I treat the bones like a built-in roasting rack and let them shield the meat a bit from direct heat. I still dry brine, tie between the bones if it looks loose, and use the same binder and rub, but I expect it to take a little longer to reach temp because of the extra mass. When I slice, I like to cut the bones off in one slab first and then slice the roast into thick slices; the bones stay in the kitchen as the cook's bonus, and the plate still looks like the same signature coffee-rubbed, cherry-smoked prime rib I've been aiming for from the start.
Make-Ahead, Storage, and Reheating
How far ahead you can dry brine
For this roast, I like a good overnight dry brine, but I'm very comfortable going out to about 24-36 hours if my schedule is tight. I salt it, set it on a rack, and let it hang out uncovered in the fridge so the surface dries a bit and the salt has time to move inward; any longer than about a day and a half, and I personally start to worry about it tasting a little too salty for my liking.
Holding the roast if it finishes early
If the roast hits temp earlier than I planned (it happens), I pull it, tent it loosely with foil, and tuck it in a warm spot while I get everything else caught up. When I need to hold it longer-say up to an hour-I wrap it in foil, set it in a dry, room-temp cooler, and let the insulation work for me; it stays hot enough to be pleasant, but not so hot that it keeps overcooking.
Storing and reheating leftovers without drying them out
Leftovers go into shallow containers with a little bit of au jus spooned over the top so the meat has some moisture to sit in. When I reheat, I keep the slices on the thicker side and warm them low and slow-either covered in the oven with extra jus or gently in a skillet with a splash of broth-so they come back to life instead of turning gray and tough. This is my go-to plan when I'm making prime rib sliders or "fancy" leftover sandwiches the next day. The same gentle reheating rules I follow here apply to leftover ribs too - my How I Cook Ribs at Home guide has a whole section on keeping pork ribs juicy the second day.
Freezing and thawing smoked prime rib
If I know I'm going to freeze some, I slice the roast first, then wrap the pieces tightly in smaller portions so I'm not thawing more than I need. I like to freeze them with a bit of au jus in the package, then thaw in the fridge and reheat gently in a covered pan with more jus; it's as close as I've gotten to "fresh" prime rib from the freezer without drying it out.
Variations and Substitutions
Herb-only rubbed smoked prime rib
If I'm cooking for someone who isn't excited about coffee in a rub, I strip it back and lean hard into herbs, garlic, and pepper instead. I still dry brine the roast, then coat it in a mix of kosher salt, cracked black pepper, dried (or fresh) rosemary, thyme, and plenty of granulated garlic and onion so the bark tastes like the best classic roast beef, just with a hint of smoke. I make this version when I want the flavor to feel familiar and "holiday traditional," but still clearly cooked on the smoker.
Peppercorn-crusted prime rib
For a more assertive crust, I swap the coffee rub for a heavy-handed peppercorn crust, using a mix of cracked black, pink, and sometimes green peppercorns so it's punchy but not one-note. I press the pepper mix onto a well-salted, lightly mustard-coated roast, then smoke it the same way; the result is a prime rib that tastes like a giant, smoky steak au poivre. This is my go-to when I know the table is full of steakhouse people who love that sharp pepper bite with rich beef.
Horseradish cream sauce instead of au jus
On nights when I don't feel like babysitting a pan sauce, I skip the au jus and serve the prime rib with a cool, tangy horseradish cream instead. I stir prepared horseradish into sour cream or crème fraîche with a bit of Dijon, lemon, salt, and pepper, then chill it so it thickens and mellows a bit before dinner. I make this when I want a bright, zingy contrast to the smoky, fatty meat-the kind of sauce people keep dragging their fork through long after the meat is gone.
Frequently Asked Questions
Yes. If I don't have the pellet smoker handy, I treat my oven like the "low-and-slow" part and add smoke with a short stint on a grill or a smoking tube. You won't get quite the same level of smoke, but the dry brine, coffee rub, and reverse sear still give you a really close version.
If I'm in a rush, a few hours of salt is better than nothing, but the roast is always noticeably better after an overnight dry brine. The meat tastes seasoned all the way through instead of just on the outside, so I try hard to give it that extra time.
No, at least not in a "drinking a latte with your steak" way. I use coffee because it deepens the crust and adds a gentle bitterness that balances the fat; most people just taste a rich, complex bark and don't realize coffee is in there until I tell them.
It happens to me, too. I pull it off the heat, tent it with foil, and tuck it into a dry cooler or warm corner of the kitchen; it stays hot and juicy for quite a while, and you can always give it a quick reverse sear right before serving to re-crisp the crust.
I slice the meat a little thicker, store it with some of the au jus, and reheat it gently with more liquid-either covered in the oven or in a skillet over low heat. The goal is to warm it just until it's pleasantly hot, not to recook it.
