I truly enjoy eating and cooking cornish hens!
I prefer to cook them in my roaster at a low setting to allow all the natural flavors to mingle with each other...lol but if you don't have a roaster you can use your oven.
What I do is preheat the oven on 400 degrees while I'm cleaning the hen or hens.
After, the cleaning rather I use the roaster or the oven I pat my the hen with a paper towel to get rid of some of the excess water.
If I'm using the roaster I don't worry about foil but if I'm using the oven I line my pan with foil but I also pull off extra so that I can cover the hen with the foil after I season it to help keep in the moisture of the hen.
When seasoning my hen it really depends on how I feel
I will use sage, polutry seasoning, peper, Nature's Seasoning, Garlic Powder or Onion Powder!
NOTE: I MAY USE A COMBINATION OF ALL THE SEASONINGS OR I MAY LEAVE SOME OUT IT TRULY DEPENDS WHAT I HAVE A TASTE FOR!
I also cut margarine or butter and place it around the hen to help it get that golden brown color!
I have tried that spray butter but I don't like the taste of the skin when the dish is done so I stick with the real stuff in regards to that!
When you place your hen in the oven turn it down to about 300 to 350 degrees.
After about 30 mins you can base the hen by dipping a spoon or a baser in the juices in the pan and drizzle it back over the hen then place the foil back over the hen.
let it cook for about 30 more mins and repeat the first step but this time keep the foil off of it so that the hen can get brown.
If you have it in the roaster you can base the hen and just let it continue to cook and will get a great golden brown skin.
Let the hen rest for about 5 mins then cut and serve!!!
I am not a chef but I am a home cook these are steps that I use when cooking I am not responsible if something isn't done correctly.
