Method

Roast Beef

  1. 1

    Prepare the Beef

    Preheat the oven to 300°F (150°C). Pat the beef roast dry with paper towels and season generously with salt, black pepper, garlic powder, onion powder, thyme, and rosemary, rubbing the seasonings into the meat.

  2. 2

    Sear the Beef

    In a large skillet, heat the olive oil over medium-high heat. Sear the beef roast on all sides until browned, about 3-4 minutes per side.

  3. 3

    Slow Roast the Beef

    Transfer the seared beef to a roasting pan and place in the preheated oven. Roast for about 3 hours, or until the internal temperature reaches 135°F (57°C) for medium-rare, or longer for desired doneness.

  4. 4

    Rest the Beef

    Remove the roast from the oven and let it rest for 15-20 minutes before slicing.

Mashed Potatoes

  1. 5

    Prepare the Potatoes

    While the beef is roasting, peel and cut the russet potatoes into chunks. Place them in a large pot and cover with cold water.

  2. 6

    Boil the Potatoes

    Bring the water to a boil over high heat, then reduce to a simmer. Cook the potatoes until fork-tender, about 15-20 minutes.

  3. 7

    Mash the Potatoes

    Drain the potatoes and return them to the pot. Add the butter, heavy cream, salt, and black pepper. Mash until smooth and creamy.

Gravy

  1. 8

    Make the Gravy

    Once the roast has rested, pour the beef drippings from the roasting pan into a saucepan. Over medium heat, whisk in the flour until it forms a paste (roux). Cook for 1-2 minutes.

  2. 9

    Add Broth

    Gradually whisk in the beef broth, stirring constantly. Bring to a simmer and cook until the gravy thickens, about 5-7 minutes. Season with salt and black pepper to taste.
