- 1 Prime Rib Roast (make sure to keep the weight)
- 2 sticks of butter
- Rough Cut (B’s Rub)
- Montreal Steak Seasoning
- Kosher salt
- Cell phone (or calculator/timer)
Step 1: Let roast rest at room temp for 6 hours
An important step in this process is to let the roast rest at room temperature for at least 6 hours or overnight to ensure even cooking.
Step 2: Make a compound butter
Mix a seasoned butter to cover the roast and create a delicious crust for your prime rib.
Step 3: Cover the roast in the butter
Cover the roast in the compound butter with a spatula.
Step 4: Heat oven to 500 degrees
Heat up your oven to 500 degrees. Get ready for some easy math to get your initial sear time.
Step 5: Calculate your initial sear
Multiply the weight of your rib roast by 5. In this case, we had a 4 pound prime rib times 5. 4×5=20 minutes. Round up to the nearest minute and get the rib roast in the oven for that sear time
Step 6: Shut off oven and wait for 2 hours
That’s it! Don’t open the oven. Don’t even look at it. Just set a timer for two hours and relax. Then get ready to enjoy your perfect medium rare prime rib when it’s ready after two hours.
