Prime rib is definitely one of my favorite cuts of beef, and as luck would have it, it's also one of the most expensive.😬 This means you HAVE to get the recipe right, or you will have wasted hundreds of dollars, am I right?

No pressure, I've got your back with this foolproof smoked prime rib recipe.

🧐 Why This Recipe Works

There are so many reasons why this gluten-free and GMO-free Smoked Prime Rib Recipe is amazing. First, the simple prime rib rub consists of kosher salt, freshly ground black pepper, Montreal steak seasoning, and a small amount of cayenne pepper. Together, they do a perfect job of flavoring the rib roast.

The salt in the smoked prime rib rub will first draw the moisture out of the prime rib roast, forming a dry crust around it. You may think you've ruined the prime rib, but not to worry! Through the amazing process of diffusion, the meat will not only absorb the seasoning but also the moisture back into the meat.

Finally, we're slathering a mixture of butter, garlic, and herbs all over the roast, which will provide an incredibly flavorful and crispy crust, especially since we are making reverse sear prime rib.

Are you familiar with reverse searing? When you reverse sear prime rib, it simply means that the meat is seared at the end of the cooking time instead of at the beginning.

🛒 What Goes Into This Recipe

🔖 Ingredients & Substitutions

• Beef Prime Rib: Choose an 8-10 pound standing prime rib (bone-in). This means that the rib bones are still attached and allow the rib to stand on the bones. The bones add flavor, so avoid buying a boneless roast. Some people like to remove the bones and use them as a base to rest the roast onto, this also makes the finished prime rib easier to slice.
• Butter: Instead of olive oil, this recipe calls for unsalted butter. Since the roast will already be heavily seasoned with kosher salt, avoid using salted butter.
• Herbs: Although I added dried rosemary, thyme, and herbs de province to the butter and garlic crust mixture, fresh herbs can definitely be substituted. If you do use fresh herbs, use 3x the amount.
• Montreal Steak Seasoning: If you don't have Montreal Steak Seasoning on hand, it's ok to leave it out.
• Cayenne Pepper: The cayenne pepper adds a bit of heat which is not necessarily traditional, but our family loves it. It can easily be left out.
• Garlic:There is no need to include garlic powder in the dry rub because we will be using an entire clove of garlic in the herbed garlic butter crust.

🍖 How to Smoke A Prime Rib

Day 1 | Season Prime Rib and Prepare Herbed Butter

Step 1: Wash and dry prime rib, then set it onto a pan. If the roast has a thick fat cap, trim some of the fat from the top of the roast.

Step 2: Mix kosher salt, freshly ground black pepper, Montreal steak seasoning, and cayenne pepper in a small bowl.

Step 3: Rub the seasoning into the prime rib. Go a little lighter on the ends, to keep them from being overly salty. Place on a rack over a tray and refrigerate overnight, uncovered.

Pro Tip: This method of drying the roast in the fridge is called dry brining (some call it dry-aging, but dry-aging takes a lot longer). This same method is also used in my son's outstanding Grilled Ribeyes Basted in Butter recipe.

Step 4: Prepare Herbed Butter: Add softened butter, herbs, and garlic cloves to a food processor (paid link). Blend until a paste is formed.

Step 5: Using a spatula, transfer the herb mixture into a small Ziploc sandwich bag and roll it into a log. Refrigerate the herbed butter until needed.

Day 2 | Smoking the Prime Rib

Step 6: Six hours before you plan on eating the prime rib, pull it out of the fridge along with the butter. Give it 2 hours to come to room temperature.

Step 7: After the prime rib has rested for 1 hour and 45 minutes, set your Traeger or electric smoker to225 degrees F.SelectSuper Smoke and preheat 15 minutes. Spread half of the herbed butter over the prime rib, then place prime rib on the grill. Insert the probe or a meat thermometer into the thickest part, and set the probe temperature to 120℉.

Step 8: Begin checking the internal temperature after 3 hours. When the roast reaches 120℉, pull it off the grill and allow it to rest for 15 minutes. Meanwhile, kick up the Traeger's temperature to 450°F.

Step 9: Right before putting the prime rib back on the grill, brush the remaining herbed butter all over it. Re-insert the probe into the thickest part, and set the probe temperature to130°For 135°F for medium-rare to medium.It should take approximately 15-20 minutes to get to that temperature.

Pro Tip: Remember that the Traeger prime rib temperature will continue to rise during the resting period.

Rest Traeger Smoked Prime Rib Roast Before Serving

Step 10: When the smoked prime rib is ready, remove from the grill and wrap in foil for 15 minutes. If it's going to be a while before you serve it, wrap the foil-wrapped roast in a clean towel and place in a small cooler (without ice) until ready to serve.

Many factors can change these times including the temperature of the meat, the temperature of the grill, the temperature outside, and how many times you lift the lid to sneak a peak.

• 4 to 5 pounds: 2 — 3.5 hours
• 6 to 8 pounds: 3 — 4.5 hours
• 9 to 10: pounds: 4.5 — 6.5 hours

🤷🏻‍♀️ Recipe FAQs

👩🏼‍🍳 Pro Tips

• When seasoning the roast, use a large cookie tray underneath. The excess seasoning will land in the tray and can be used to season the areas you missed.
• It's important to bring the prime rib to room temperature before it is smoked. Smoking a cold roast will add to the cooking time and who needs that?
• Do not raise the lid of the smoker while smoking the prime rib. It reduces the temperature inside and adds to the cooking time.
• This recipe calls for cooking the meat low and slow. If you want to shorten the cooking time, you can kick up the temperature to 250℉.
• If you'd like to make au jus to serve with the sliced Traeger prime rib, smoke the roast in an aluminum pan or tin to collect the yummy juices.
• Resting the roast allows the juices to redistribute, so don't skip that part!
• If you decided to debone the prime rib, use butcher's twine to secure the prime rib over the bones so that the roast has a natural rack to stand on as it smokes.
