A few pieces of advice before you cook your roast beef:

  • To roast any meat, try to use cookware made of aluminum, stainless steel, or cast iron. The reason is that these materials are excellent conductors of heat and distribute heat evenly to the roast.
  • To cook the meat evenly, use a pan that holds the beef well but is not bigger than the size of the roast beef.  If you use a large pan with empty spaces, the water which comes out from the beef will evaporate sooner than it should and cause the meat to scorch.
  • If you use a smaller pot, the air circulation is compromised and the roasting and browning of the meat do not happen efficiently. 
  • Try to use a shallow pan for the best result. A shallow pan is better suited to roasting while a deeper pan would cause the water to evaporate and escape. As a result, the beef gets steamed instead of roasted.
  • After you take the roast out of the oven, let it sit for at least 3 minutes. Doing so, not only brings the beef to a safe temperature but also redistributes the meat juices throughout the meat.
