Here is a general roast beef cooking time chart based on the weight of the roast:
Weight | Rare (120-125°F) | Medium Rare (130-135°F) | Medium (140-145°F) | Well Done (150-155°F) |
---|---|---|---|---|
2-3 lbs | 35-45 minutes | 45-55 minutes | 55-65 minutes | 65-75 minutes |
4-5 lbs | 45-55 minutes | 55-65 minutes | 65-75 minutes | 75-85 minutes |
6-7 lbs | 55-65 minutes | 65-75 minutes | 75-85 minutes | 85-95 minutes |
8-10 lbs | 65-75 minutes | 75-85 minutes | 85-95 minutes | 95-105 minutes |
Please keep in mind that these times are only a general guide, and the actual cooking time can vary depending on a number of factors, such as the desired doneness, the type of oven, and the starting temperature of the roast. It’s always a good idea to use a meat thermometer to check the internal temperature of the roast, as this is the most accurate way to determine doneness.
