HOW TO COOK CHATEAUBRIAND IN THE OVEN RECIPES

Steps:

• "According to Wikipedia, the same cut of beef can be called Chateaubriand, tournedos, filet de bouef (French), Medallians, Tenderloin Steak (USA), or Fillet Steak (UK and Ireland). The two secrets to this simple recipe are (1) a grill pan, and (2) RESISTING the temptation to turn the steak too frequently. (A grill pan is a large saute pan that has raised grill ridges.) I've grilled filet mignon before, and it's terrific, but this is one of the few cases where I actually prefer the grill pan -- it sears with a moister method than grilling -- it cooks nearer to its own juices, making it less likely to dry out. Place the pan over medium high heat, and allow to come up to temperature (approximately 4-5 minutes). Add 1-2 tablespoons of vegetable oil and tilt it around to cover the pan. Slice medallions in very consistent-thickeness slices, approximately 1 inch thick. Cover with ample ground course salt and pepper. Place tournedos (fillets), putting them down away from you, one by one, into the pan. DO NOT DISTURB them for 3 minutes. Lift with tongs and flip. Wait another 2-3 minutes. Rotate 45 degrees, and sear for another 2 minutes. Flip again to complete the grill marks, and cook another 1-2 minutes. I like my steaks medium, and I carefully watch the color on the outside -- remove them from the grill pan when there is still a faint pink line in the center. Tonight I found that cooking time for me was about 5-6 minutes total. "

Steps:

• Preheat the oven to 400 degrees F. Season the beef with salt and pepper. In a large skillet, over high heat, melt the butter. Add the beef and sear for a couple of minutes on each side. Place in the oven and roast for 20 to 25 minutes for medium rare. Remove from the oven and rest for 5 minutes before slicing. Serve with potatoes and chateaubriand sauce
• For the potatoes: In a saute pan, over medium heat, melt 8 tablespoons of butter. Add the potatoes and season with salt and pepper. Saute the potatoes for 3 to 4 minutes. Place the potatoes in the oven and roast the potatoes until golden brown and tender, about 20 minutes, shaking the pan every 5 minutes. Remove from the oven and add the parsley. For the Sauce: In a saucepan, combine the vinegar, wine, peppercorns, shallots, and tarragon. Bring the liquid to a boil and reduce to 1 tablespoon. Add 1 tablespoon of water. Combine the reduced liquid and egg yolks in a stainless bowl, over simmering water. Whisk until frothy. In a steady stream, add the butter until the sauce thickens. Season with salt and pepper. Strain the sauce through a chinois and set aside.
