How Long to Cook Prime Rib at 350


Prime rib is a delicious cut of beef that you’re probably not eating as often as you should. It’s ideal for holidays, special occasions and when you just want to treat yourself. But how long do you need to cook prime rib in order to get it perfectly done? And what temperature should it be when you pull it out of the oven? In this article we’ll discuss both questions so that your next prime rib meal will be perfect!

Preheat oven.

Before you start cooking, you’ll want to preheat your oven. This will allow it time to heat up while you prepare the rest of your meal. If possible, set the temperature to 350 degrees Fahrenheit and allow 30 minutes for this step (or longer if necessary).

Remove roast from wrapping and place on a rack in pan that has been lightly coated with cooking spray.


Now that you have a roast, it’s time to cook it. The first step is removing it from its packaging and placing on a rack in pan that has been lightly coated with cooking spray. Don’t use foil or plastic wrap–this will keep the juices from escaping and make for an unevenly cooked prime rib. Also, don’t use a roasting pan that’s too small; you want plenty of room for air circulation around your meat so all sides get evenly crisped up before serving time rolls around!

Rub roast with oil and sprinkle with salt, pepper and garlic powder.

So, you’ve got your prime rib, and now it’s time to make it even more delicious. Rubbing the meat with oil will help keep it moist as it cooks. Sprinkle on salt and pepper for flavor–and don’t forget to add garlic powder for a little kick!

Place in oven for 15 minutes per pound or until internal temperature reaches about 135degrees.

Place the roast in a roasting pan and cook at 350degrees for 15 minutes per pound or until internal temperature reaches about 135 degrees. If you are cooking a larger roast, you may need to cook it for longer.

The internal temperature should be 135 degrees before you take it out of the oven

After you’ve cooked the meat to 135 degrees, take it out of the oven and let it rest. It’s important to let your prime rib rest before carving because this allows all those delicious juices to redistribute throughout the meat. If you cut into it too soon, those juices will run out and leave dry pieces of prime rib behind.

The proper amount of time for resting is 20 minutes per pound (1 hour total). This means that if you have a 7-pound piece of prime rib, then your total resting time should be 1 hour and 20 minutes after removing from heat.


Now you know how long to cook prime rib at 350 degrees. When it comes to cooking this delicious cut of meat, there’s nothing better than knowing exactly what temperature your meat is at and how long it’s been in the oven. With these tips, you should be able to perfectly prepare any type of roast or steak without any hassle!
