Go in at an angle in the middle of the cut, wait for a second, and then touch the tester to your wrist. If it’s cold, the meat is raw. If it’s warm—close to your body temperature—then the meat is medium rare. If it’s hot, it’s well done.
Also know, can you undercooked prime rib?
Just like any raw or undercooked meat, poultry or seafood, a Consumer Advisory for raw or undercooked animal products is required if you serve the prime rib roast undercooked. Also, an undercooked item must be per consumer request, so you cannot serve undercooked prime rib roast as a standard practice.
Similarly, do you leave a thermometer in food while cooking?
Yes, you can leave your meat thermometer in the meat while it’s cooking as long as the thermometer’s manufacturer says it’s oven-safe. Thermometers that are safe for use while cooking should have a clear “oven-safe” label.
Do you really need a meat thermometer?
The first and foremost reason you should invest in a meat thermometer is food safety. The Centers for Disease Control and Prevention (CDC) recommends cooking foods thoroughly and checking them using a meat thermometer to avoid nasty foodborne illnesses like Salmonella or norovirus.
If you don’t have a meat thermometer, check your beef is roasted by piercing it with a skewer. The juices should run red for rare, pink for medium and clear for well-done.
Verifying Doneness: Cook your Prime Rib Roast until the lowest internal temperature you can find with an instant-read thermometer is 125°F (52°C) for medium rare or 130°F (55°C) for medium doneness. Resting: Remove the roast from the oven. Loosely tent with foil and let it rest on the counter for 30 minutes.
The more undercooked it is, and the sooner you want to eat it, the thinner you’ll want to slice it. Place the meat in an oiled roasting pan or Dutch oven; drizzle it with some stock, sauce, or water; cover it with aluminum foil; and bake the whole thing in a 400° F oven until cooked.
First, we were taught to salt and season the roast the night before, and allow the roast to sit overnight, uncovered, under refrigeration. The salt draws out the moisture and then – only with time – it grabs the seasonings and infuses it back into the meat.
Relax your face—no smiling or grimacing. Now touch your finger to the fleshy part of your cheek: this is the way a rare piece of meat will feel. Touch your chin, right above the point but well below your lower lip. This slightly firmer feel is analogous to a medium-rare doneness.
Roast in the oven until the thermometer registers

Aim for 115 to 120°F for medium rare (125 to 130°F after resting), or 125 to 130°F for medium (135 to 140°F after resting). And remember, a roast will continue to rise by 5 to 10°F as it rests (see rule #13 below), so make sure to pull it out early to account for that!
When checking the temperature of your prime rib roast, insert meat thermometer so tip is in thickest part of beef, not resting in fat or touching bone. Cook until rib roast reaches an internal temperature of 120 degrees F. (or your desired temperature).
