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.
The best way to safely thaw ground beef is in the refrigerator. Keeping meat cold while it is defrosting is essential to prevent growth of bacteria. Cook or refreeze it within 1 or 2 days. To defrost ground beef more rapidly, you can defrost in the microwave oven or in cold water. If using the microwave, cook the ground beef immediately because some areas may begin to cook during the defrosting. To defrost in cold water, put the meat in a watertight plastic bag and submerge. Change the water every 30 minutes. Cook immediately.
