Tips to Cook Prime Rib at 225 Degrees
- Prime rib is simply the beef sliced from the rib portion, specifically ribs 6 to 10. It is also known as “standing rib roast when presented on the bone.” The origins of ribeye steaks can be traced back to this region. It’s juicy, well-marbled, and very delectable.
- You can buy boneless prime rib, but I recommend roasting it on the bone for the finest flavor, juiciness, and texture.
- You can budget 1 pound per person for a bone-in rib roast. Meanwhile, calculate ¾ pounds per person for a boneless roast. Yes, this amount of beef should suffice!
- If you are lucky, you’ll have enough leftovers to create French dip sandwiches or other meals.
- Bones don’t contribute flavor, but they help regulate temperature, which means you’ll get more tender, medium-rare meat in the finished roast. And, of course, when you’re done, you get to nibble on those bones.
- Season it well. Though there is no need to add much more than a decent heavy dusting of salt and pepper to prime rib because it has plenty of flavor on its own.
- You can also season it ahead of time. If you have the time, season the prime rib with salt at least a day ahead of time and up to four days ahead of time, allowing it to lay on a rack in your refrigerator uncovered. This will give the saline more time to infiltrate and season the surface while drying it off, resulting in greater browning during roasting.
- Allow the roast to air-dry on a rack in the refrigerator overnight before roasting to improve the crust. Seasoning the meat with salt up to a day ahead of time can help the seasoning sink deeper into the meat.
- Slow roasting allows the prime rib to cook more uniformly, resulting in soft, juicy pink flesh from end to end. Because the outside of the roast cooks faster than the inside, the outer layers of the rib roast develop a thick “grey ring” of overcooked flesh. Many recipes call for browning the prime rib in a hot oven before lowering the temperature. The issue with that method is that it leads to uneven cooking.

How to Cook Prime Rib at 225 Degrees
This recipe is suitable for prime rib roasts ranging in size from two to six ribs. One pound of bone-in roast per guest is a good estimate. (Each rib adds around 1.5 to 2 pounds to the roast.) Use a dry-aged prime-grade or grass-fed roast for the finest results.
- Start by trimming your prime ribs to your preference.
- Then proceed to salt the roast generously.
- Make sure you insert a thermometer probe near the edge of the roast, set the low-temp alarm to 30°F (-1°C), and then the roast in the freezer.
- Proceed to preheat the oven to 225°F (107°C) in the meantime.
- Remove your roast from the freezer when the low-temperature alert goes off.
- Over high heat, heat a heavy skillet – cast iron might just be the ideal choice to make.
- In a skillet, sear the roast on all sides.
- Then proceed to season to taste with pepper and/or additional ingredients.
- Place the roast on a rimmed baking sheet on a rack. Set the high-temperature alarm for 125°F (52°C) and insert a probe into the very center.
- Proceed to cook the roast until the high-temperature alarm goes off in the oven. Make sure there are no lower temperatures in the meat.
- Remove the meat from the oven and cover it with foil to rest for 30 minutes.
- After that, carve the meat and serve
