I usually broil oysters for about 5 minutes when I cook them, but they won't fit in the pan. Can I get the same result from cooking them in a 500 degree oven? How long?
Sure, you can do that. What I would do is pre-heat the oven and line a halfsheet pan with rock salt and have that in the oven as it is pre-heating so that the salt is super hot too. Shuck the oysters, deep side down and place in the hot rock salt and roast about 5 minutes or maybe less. Watch for the edges of the oysters just begin to curl, Of course raw oysters on the half shell are divine too. 'thoug one thing that might have contributed to muy becoming a 'hound were oyster roasts in Savannah as a kid. Outdoor BBQ pit, roaring hot fire, big bunches of oysters plunked down on top of seaweed that was on top of really hot sheet metal and covered with wet burlap bags and steamed open. Back then we dipped them in melted butter and sometimes added catsup and lemon. Sigh! It has been a long time since I had an oyster roast.
