How long should I cook a 32-36oz lobster tail?

I'm really not sure how to cook lobster at all, but I won't be grilling it. I want to butterfly the meat, but if wrapping the tail in foil and baking will insure the meat cooks evenly I'll do that. I'm open to preparation suggestions.How long should I cook a 32-36oz lobster tail?
I am a former chef and do it as you said, I would season it lightly or if you like with a garlic butter preparation, and wrapped in foil at 375 d F for 20-25 minute is fine, let it cool for a few minutes and serve.How long should I cook a 32-36oz lobster tail?
A solid way to cook a lobster tail is to boil it partially and then broil it in an oven. Typically for whole lobsters, you add 5 minutes of cook time for every pound. Being that this only a tail, the cook time shortens a bit. Boil it in some old bay flavored water for 4 minutes, then split it open and butterfly, add some whipped butter and seasoning to the tail meat and broil in the oven for a minute or two. This process has worked for me many times.
