When you’re cooking a prime rib, it’s always important to keep an eye on the clock. You don’t want to overcook your meat and have it dry out, but you also don’t want to undercook it leaving the center raw. I’ve found that cooking times vary depending on the size of your roast, but if you start with one five pounds or more, then expect to cook it for at least 20 minutes per pound in an oven set at 450 degrees F. That means that if your roast weighs between four and six pounds (as most do), then plan on 30-36 minutes per pound total time from when you put it in after preheating!
Preheat the oven to 450 F.
Preheat the oven to 450 F.
In order to get an accurate reading of your oven’s temperature, use an oven thermometer to check it. If you don’t have one, you can use a laser thermometer or even just stick your hand in there and see how hot it feels (but don’t burn yourself!). If the oven isn’t hot enough, turn up the heat until it reaches 450 F; if it is too hot already, turn off 5 degrees at a time until you find a good medium between 400 F and 450 F that works for this recipe.
Once your roasting pan is preheated and ready for action, set your timer for 20 minutes–this will give us plenty of time to get everything else ready before we need to add our meat into its final resting place!
Place the prime rib in a roasting pan and rub it with butter.
Prime rib is a beef roast often cooked at high heat. It’s usually roasted to medium-rare, but you can cook it to your liking.
To start, place the prime rib in a roasting pan and rub it with butter. Place it in an oven preheated to 450 degrees Fahrenheit for 20 minutes, then reduce the temperature to 325 F and cook for another 45 minutes per pound (for example: if you have a 5-pound roast, you would cook it for about 2 hours 15 minutes).
Cook for 10 minutes per pound at 450 F and then lower to 350 F.
You can use a 10-minute per pound rule of thumb to cook your prime rib. For example, if you have a 5-pound roast, it will take 50 minutes to reach the desired temperature at 450 F and then lower it to 350 F for another hour or so.
This method is good because it allows the meat some time at a high temperature without drying out too much before reducing the heat (you want your meat tender). However, there are other ways you can go about this as well!
A 5 Lb Prime Rib will take approximately 20-25 minutes per pound to cook
A 5 Lb Prime Rib will take approximately 20-25 minutes per pound to cook.
If you prefer a medium-rare prime rib, cook it for 20 minutes per pound.
If you prefer a medium prime rib, cook it for 22 minutes per pound.
So, there you have it. A 5 Lb Prime Rib will take approximately 20-25 minutes per pound to cook and should be served at around 125 degrees F.
