Before I cook the halibut, I lightly salt with sea salt on both sides. I also add a bit of course ground black pepper. In the pan, I put a small amount of oil. My favorite to use is coconut oil but I will also sometimes use extra virgin olive oil. Occasionally, I will use organic butter. I cook the halibut on a very low fire because although it is not as delicate as some white fish, it is still pretty delicate and it is really easy to over-cook it. If it starts to stick at all, I add a few drops of water to prevent it from browning on the bottom because to me this can ruin the flavor if it browns too much (a little brown is good). Then right before I take it out I squeeze fresh lemon all over it. I serve it up and eat it hot. Yummy! It takes about 5-7 minutes to cook it this way.
There are some slight variations I use sometimes to this simple method. Sometimes, I add garlic to the oil for a little garlic flavor. Other times I add fresh herbs, dill weed being my favorite since it goes especially well with the lemon.
Using this simple cooking method, you can really taste the natural sweet flavor of the halibut and it is delicious.
