How to cook a Wagyu Prime Rib French Dip

Preparing the Wagyu Prime Rib

Season a prime rib roast with salt, pepper and garlic powder then let it sit in the fridge overnight. Letting the meat season overnight allows the seasoning to penetrate into this large cut resulting in flavorful beef. I always make sure to heavily season large cuts of meat because the seasoning does not reach the inside.

I got a boneless wagyu prime rib roast from Snake River Farms. Their wagyu beef quality is next to none and these roasts have insane marbling which means they have a ton of flavor in them! Be sure to check them out if you’re looking for high quality meat this holiday season.

Smoking the Prime Rib

Preheat the smoker to 275° F using hickory wood for a bold smoky flavor. I used my Kamado Joe Classic II for this cook. The Kamado Joe is super versatile in the fact it can transform from a smoker to a grill just by adjusting the vents. This works great for the reverse sear method, allowing you to only have to use one cooker.

For the French dip au jus, combine in a foil pan or large cast-iron skillet: 3 sliced onions, 4 cloves minced garlic, 1 tbsp beef bouillon, 4 cups beef broth and 1 tsp salt. Mix thoroughly, then place the prime rib on a wire rack over the top of the foil pan to catch the meat drippings as it cooks.

I inserted my MEATER Plus into the prime rib roast for this cook. The wireless meat thermometer allows me to monitor the internal temperature of the roast at all time throughout the cook. This will result in perfectly cooked prime rib and takes the guess work out of the cook.

Place the pan and the roast on the preheated smoker indirect of the heat . The cooking time for this is about 2 hours at 275° F. You can reduce the cook time by 25% by increasing to a medium heat of 325°F. Physically check on the roast every 30 minutes to make sure everything looks good and one part of the roast is not cooking quicker than others.

Remove the roast once it reaches an internal temperature of 120° F. Increase the cooking temperature to high heat to sear the roast and give ti more flavor.

Sear the roast over direct heat on all sides then remove it once the internal temperature reaches 130° F for a perfect medium rare.

Make the Wagyu Prime Rib French Dip

Place the roast on the cutting board and cover with aluminum foil then let it rest for 30 minutes. Resting the roast allows the juices to redistribute back into the meat. As the roast rests, keep in mind that it will continue to cook and rise about 10 degrees in temperature.

Once the roast is done resting, thinly slice it against the grain using a sharp carving knife or a meat slicer. Cutting thin slices will allow for a more tender bite since we’re using it for a sandwich. If you were serving the prime rib by itself, you can cut it as thick or thin as you like since you use a knife to eat it.

Assemble 6 oz of thinly sliced prime rib on the toasted hoagie buns, add a layer of cooked onions from the au jus, then top with 2 slices of provolone cheese. Put the sandwich on a baking sheet then place it in a preheated oven under the broiler for 2 minutes until the cheese is melted.

Cut the sandwich in half, then serve it up hot with a side of potato chips. Dip it in a small bowl of the au jus and enjoy!

Have leftover prime rib?

If you end up having leftover beef, store it in an airtight container for a few days. I like to cook a cold slice of it in a skillet with melted butter over a medium-high heat. Serve it up with some eggs and hash browns for a super delicious breakfast!

Another great way to enjoy the leftovers is to thinly slice it an make some Prime Rib Sliders. Dip them in the leftover au jus for one delicious bite.

You can also vacuum seal the leftover prime rib roast and place it in the freezer to enjoy another time. Cut it up into small pieces and use it in a chili or even use it for taco meat. The possibility are endless!
