BAREFOOT CONTESSA BEEF TENDERLOIN RECIPES

Steps:

• For the beef: Preheat a pizza oven or regular oven to 400 degrees F.
• Sprinkle the tenderloin with all the herbs and salt and pepper. Heat a 14-inch cast-iron pan over medium-high heat and add 1/4 cup cooking oil, heating until hot. Add the tenderloin and sear until golden brown, about 5 minutes on each side. Once almost browned on the second side, add the butter and let melt. Transfer the pan to the oven to continue cooking until your desired doneness, or 12 minutes for medium-rare. Allow to rest for 10 minutes, then slice into 1- to 1 1/2-inch-thick slices.
• For the Armagnac sauce: Add the beef fat to a large Dutch oven over medium-high heat and let melt. Add the bones and sear just until some of the bone marrow has begun to melt, about 5 minutes. Transfer to the oven and roast until dark and golden, about 15 minutes. Add the carrots, celery, onion, garlic and porcinis. Put back into the oven and allow to brown another 10 minutes.
• Transfer the pot to the stovetop. Add the rosemary, sage and Armagnac. Allow the alcohol to ignite and immediately cover with the lid. Place over medium heat and bring to a simmer. Add the veal demi, chicken stock and green peppercorns, stirring to combine. Simmer, covered, for 30 minutes over medium heat.
• Carefully strain the Armagnac sauce directly into a medium saucepan and whisk in the cold butter until thoroughly combined.
• For the wild mushrooms: Turn the heat on under a 12-inch cast-iron pan to medium-high until hot. Add the mushrooms and allow to get hot again, then add the butter and allow the mushrooms to brown all over, about 10 minutes. Add the parsley and rosemary and stir to combine. Taste and adjust seasoning as needed with salt and pepper. Keep warm until ready to serve.
• For the gremolata: Add the panko to a large cast-iron pan and allow to toast over medium-high heat, about 2 minutes. Add the butter and allow to brown, another 2 minutes. Add the garlic and bloom for 2 minutes. Add the parsley and chives to finish. Taste and adjust seasoning as needed.
• Add the mushrooms to the bottom of a large platter. Top with the sliced tenderloin, then spoon the sauce around the outside of the mushrooms. Top the tenderloin with the gremolata and serve.

Steps:

• Preheat the oven to 275 degrees F. Line a sheet pan with aluminum foil.
• Dry the entire tenderloin with paper towels and brush it all over (top and bottom) with the butter. Sprinkle it all over with 4 teaspoons of salt and 2 teaspoons of pepper. It will seem like a lot but trust me, it's important.
• Place the filet on the sheet pan and roast it for 1 to 1 1/4 hours, until an instant-read thermometer inserted into the end of the beef registers 130 degrees F for medium rare. Remove from the oven, cover tightly with aluminum foil, and allow to rest at room temperature for 15 minutes. Discard the foil and allow to sit at room temperature.
• Meanwhile, place the shallots, 3 tablespoons of tarragon, the wine, and vinegar in a small saucepan and bring it to a boil over medium-high heat. Boil for 5 minutes, until only 1 tablespoon of liquid remains. Set aside to cool for 15 minutes.
• Place the egg yolks, lemon juice, mustard, 2 1/2 teaspoons salt, and 1 teaspoon pepper in the bowl of a food processor fitted with the steel blade and process for 10 seconds. With the processor running, slowly pour the vegetable oil and olive oil through the feed tube to make a thick emulsion. Add the shallot reduction and the remaining tablespoon of tarragon leaves and pulse to combine. Refrigerate until ready to serve.
• Slice the filet of beef between 1/4 and 1/2 inch thick, sprinkle with salt, and serve warm, at room temperature, or cold with the béarnaise mayonnaise on the side.
