Ingredients
- 4 ½ lb boneless prime rib at room temperature
- Flaky sea salt to taste
- 1 large brown or white onion peeled and sliced into half moons
Instructions
- Preheat the oven to 390F. Pat the beef as dry as possible with kitchen towel and season well all over with sea salt.
- Spread the onions in a pile about the same size as the beef joint in the bottom of a baking dish. Place the beef on top.
- Roast the beef for 20 minutes before reducing the heat to 340F. If you’re cooking a boned piece of prime rib, roast for a further 1 hour for rare beef, 1 hour 25 minuted for medium beef, and 1 hour 45 minuted for well done beef. If you’re cooking a rolled boneless piece of prime rib, roast for a further 45 minutes for rare beef, 1 hour for medium beef, or 1 hour 15 minutes for well done beef.
- Remove the beef from the pan and double wrap in tin foil. Leave in a warm place - reserving the pan juices to make a sauce if desired - to rest for 30 minutes before carving. Don’t be tempted to skip this step or else the beef will be tough and not entirely cooked to rare, medium or well done as it continues to gently cook during the resting period.

Notes
- Typically a 4.5lb bone in prime rib will be a 2 bone joint of beef.
- To make a quick pan sauce, add 1/2 cup boiling water to the baking dish and whisk into the onions and cooking juices, scraping the brown bits off the bottom. If you have one, drain off the fat in a separator jug. Heat the reserved juices over a medium high heat, adding hot water to reach the desired consistency, seasoning to taste with salt and Worcestershire sauce, and thickening with 1/2 tbsp cornflour mixed with 1/2 tbsp cold water to create a paste.
