ROAST BEEF WITH MUSHROOM SAUCE RECIPES

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.

Steps:

• Remove roast from refrigerator. Preheat oven to 500 degrees.
• In a small bowl, mix together salt, pepper, garlic, olive oil and red-pepper flakes to create a kind of paste. Rub this all over the roast. Place beef in a roasting pan or cast-iron skillet, fat-side up, and put in oven. Cook undisturbed for 5 minutes per pound.
• Turn off oven. Do not open oven door. Leave roast to continue cooking, undisturbed, for two hours.
• After two hours, remove roast from oven. Slice and serve alongside, ideally, a watercress salad, some skillet-fried potatoes and a small tureen of Henry Bain sauce.
