BISON CHATEAUBRIAND WITH HORSERADISH BUTTER SAUCE
1 bison chateaubriand
Salt and pepper to taste
1 tbsp vegetable oil
1/2 stick of unsalted butter
3½ tbsp horseradish, drained (not creamed)
1 tsp Worcestershire sauce
Preheat oven to 300°F.
Pat chateaubriand dry, and season with salt and pepper.
Heat oil in a large cast-iron skillet over moderately high heat until hot but not smoking. Cook for 5 minutes on each side for medium-rare.
Transfer meat to roasting pan, and place in preheated oven to finish cooking for 8 minutes.
After removing the skillet from heat, immediately add butter and horseradish, stirring and scraping up any brown bits.
Stir in Worcestershire sauce, and spoon butter sauce over chateaubriand before slicing.
