Ground beef already formed into patties or separated into smaller quantities take less time and defrost quicker. For instance, 1/2-inch (1.25-cm) ground beef patties that were frozen separately usually take about 10 hours to defrost.
Frozen beef should not be defrosted at room temperature. Harmful bacteria may grow rapidly under such conditions. The best method for thawing beef (or any other type of meat) is to place it in the refrigerator where it will defrost slowly and safely. A large cut of beef may require 2 days to defrost in the refrigerator. The meat should be placed on a plate or dish (to catch any juices that may drip from the thawing meat) and stored on the lowest shelf of the refrigerator.
