What temperature is roast beef most tender?
Roasting beef causes the muscles to contract and expel the juices in the meat. It's best to cook your roast beef to an internal temperature of around 130-1355℉ for medium-rare. The meat will be the most tender at this temperature and will retain more juices. Letting the meat rest for 20-30 minutes after cooking is critical. This will give the muscles time to relax, which helps to redistribute the juices in the meat, giving a more tender result. The internal temperature will continue to rise another 5-10°F while it rests due to carryover cooking, so remove the meat before you reach the final desired temperature.
