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.
1 If parts of the beef still seem solid, it is not completely defrosted.  If necessary, you can finish up the defrosting process in the microwave. Place the ground beef in a microwave-safe dish and cover it. Microwave on 50 percent power for 20 to 30 seconds at a time until it finishes thawing.
