An easy Cornish hen recipe is Martha Stewart's Cornish Hen with Lemon and Herbs, which flavors the birds with parsley, thyme and lemon and takes less than an hour to complete. Another is Food Network's Roasted Cornish Game Hens, which rubs the birds with salt, lemon black pepper, basil, poultry seasoning and olive oil before stuffing them with bell pepper, celery and onion to roast in the oven.
The roasted Cornish game hen recipe is made with six individual Cornish hens, rubbed with a mixture containing salt, lemon pepper, dried basil, poultry seasoning and olive oil. It is roasted with diced bell pepper, onion and celery stuffed into the birds' cavities until the birds reach and internal temperature of 165 degrees Fahrenheit.
For the Cornish hens with lemon and herbs, take two Cornish hens stuffed with fresh thyme and lemon halves and rest them on fresh thyme and parsley in a roasting pan. Rub hens with butter and season with salt and black pepper. Roast at 450 F until the thigh meat registers 180 F.
Other recipes involve making a compound butter that combines softened butter with herbs that is mixed together and then frozen. Place pats of this butter between the Cornish hen's skin and rub generously. The birds are cooked until the thigh meat registers 180 F on a meat thermometer.
