RARE BEEF TENDERLOIN RECIPES

Steps:

• For the beef tenderloin: Preheat the oven to 500 degrees F.
• Place the beef tenderloin on a baking sheet, drizzle with the olive oil and season liberally with salt and pepper. Rub the oil and seasoning evenly over the meat.
• Roast the tenderloin until an internal thermometer reads 125 to 130 degrees F for rare to medium rare, about 20 minutes. Remove from the oven, tent with aluminum foil and let rest until it reaches room temperature, at least 20 minutes. Transfer to a cutting board and thinly slice.
• For the crostini: Turn down the oven temperature to 400 degrees F.
• Put the baguette slices on a baking sheet in 1 layer. Drizzle with the olive oil and sprinkle with salt and pepper. Bake until golden brown and toasted, about 5 minutes.
• For the horseradish sauce: Add the sour cream, applesauce, horseradish, mayonnaise, breadcrumbs and chives to a medium bowl and mix until combined. Season with salt and pepper.
• To assemble: Spread a dollop of horseradish sauce onto each toasted baguette piece, add a slice of beef tenderloin and then top with another dollop of horseradish sauce and a few watercress leaves.

Steps:

• Preheat the oven to 400 degrees F.
• Heat a large ovenproof skillet over medium-high heat. Pat the beef dry and season all over with salt and a generous amount of pepper. Add the oil to the skillet and heat until shimmering. Add 1 tablespoon of the butter and swirl to melt. Add the beef and sear until mahogany brown on all sides, about 8 minutes total.
• Transfer the skillet to the oven. Roast until an instant-read thermometer inserted in the center registers 125 degrees F for medium rare, about 25 minutes. 
• Meanwhile make the ragout: Heat 2 tablespoons of the butter in a large skillet over medium-high heat. Add the mushrooms and spread them out evenly; increase the heat to high. Let the mushrooms cook, undisturbed, until browned, then shake the skillet to flip them over. Add the additional butter along the sides of the skillet as the mushrooms cook if the skillet seems very dry. Continue to cook until nicely browned, about 5 minutes. 
• Add the shallot and cook, stirring often, until softened, about 2 minutes. Season the mushrooms with 1/2 teaspoon salt and some pepper; add the thyme. Pull the skillet off the heat and add the Madeira. Return the skillet to the heat and scrape up any of the brown bits from the bottom with a wooden spoon. Add the heavy cream and bring to a boil. Remove from the heat and keep warm.
• When the beef is ready, transfer to a cutting board, tent very loosely with aluminum foil and let rest for 10 to 15 minutes.
• Slice the beef across the grain, arrange on a platter and serve with the mushroom ragout.
