Things You'll Need
Microwave-safe dish or plate
The microwave oven can be used to defrost or cook oysters. Microwave ovens vary in power and cooking times, therefore it may be necessary to experiment with your microwave to determine the ideal cooking time for your particular oven. Generally speaking, when the oyster opens it is ready to be served. About a dozen oysters can be cooked at one time. Cooking times vary, from 3 minutes for a few oysters or double that time for a dozen oysters.
Wash and scrub the raw oysters under cold running water.
Arrange the oysters on a microwave-safe plate or casserole dish. If you are cooking a dozen or so, arrange them around the perimeter of the plate first, then place a few in the center.
Microwave on high for 3 minutes for a dozen oysters. Rotate the plate.
Microwave for another 3 to 4 minutes, or until the shells pop open. If you are cooking just a few oysters, the total cooking time will be around 3 minutes.
To thaw frozen oysters, follow step 1 and then cook for 1 to 2 minutes on defrost. They can then be shucked and used as uncooked oysters.
If your microwave has a rotating carousel, combine steps 3 and 4.
