What is the proper cooking temperature of beef roast?

• A. 140 for 15 seconds
• B. 145 for 15 seconds
• C. 150 for 15 seconds
• D. 155 for 15 seconds

Answer: (B)

Cooking a beef roast successfully hinges on reaching a safe, desirable internal temperature. The recommended minimum is 145°F (63°C) in the center, followed by a rest of several minutes so the juices redistribute and carryover cooking finishes the job. This temperature gives a juicy roast with medium-rare to medium doneness, depending on the size and cut. Cooking to 140°F can leave the center underdone for many diners, while 150°F or 155°F will yield a more done, drier result. The specific “for 15 seconds” timing isn’t the deciding factor; what matters is hitting that 145°F target in the thickest part and then resting.
