Squid can most definitely be baked, but you will need to take the time to figure out how exactly to do this. It will be important to make sure that you plan ahead however much squid you want to cook as this will make a difference in the baking process. Make sure to tenderize your squid before baking it. All you will have to do is simply gently pound the squid with a mallet a few times until it has become adequately tender. You will need to make sure that you do not hit the squid so hard as to where the meat will tear though. It’s always a good idea to tenderize the meat like this before cutting it whole.
You should also keep in mind that you will want to slowly cook the squid on a low heat setting, just s if you were roasting it. When you are cooking your squid you will be able to use the high heat setting on your oven, but not for very long. It will be incredibly important to make sure that you do not overcook your meat. In order to make your calamari a bit tenderer, you may want to think about soaking it in lemon juice prior to baking it.
You should also save the ink because it can enhance the overall flavor of stews and other such dishes. The ink sac is located in the same area as the intestines so you will need to make sure that you are extra careful when trying to retrieve it. There is not going to be a whole lot of ink in there so you will need to make sure that you get every drop possible.
