What you need for slow roast prime rib recipe for all special occasions – Prime Rib Bone In – Prime Rib and Roast Seasoning ( I highly recommend this brand) – Irish butter (don't go cheap with your butter, use a high-quality grass-fed butter) – Fresh thyme – Fresh Rosemary – Chunky Sea Salt – Beef Stock or Beef Broth – Plastic Wrap – Sheet Pan – Meat Thermometer – Roasting Pan with a roasting rack
Step 1: Season roast generously with kosher salt or chunky sea salt and prime Rib seasoning and add slices of butter all around the rib roast.
Step 2: Cover loosely with plastic wrap and refrigerate, for 4-6 hours or overnight if you have time. Don't wrap the plastic wrap too tight. Step 3: Remove the roast from the refrigerator and allow the prime rib to come to room temperature on a cutting board Step 4: Preheat the oven to 200 degrees Fahrenheit. (95 degrees C) low temperature
Step 6: Bake roast in the preheated oven until internal temperature reaches 115 degrees F (46 degrees C) for medium-rare, about 3 ½ hours. Remove from the oven and tent with aluminum foil; allow to rest, for about 20 minutes.
Once the oven has come up to temperature, uncover the rested roast and return it to the oven. Bake until well-browned, 6 to 10 minutes. Slice with a sharp knife on the fat side. Serve with creamy horseradish sauce or Au jus sauce from the bottom of the roasting pan and enjoy!
