Instructions

  1. Step 1: Preheat oven to 325°F. Rub 4 lbs beef rib roast all over with 3 tsp kosher salt, 2 tsp black pepper, and 3 tbsp olive oil. Place roast on a rack in a roasting pan and tuck 2 sprigs fresh rosemary underneath. Roast for 2 to 2 1/2 hours until internal temperature reaches 130°F for medium-rare.
  2. Step 2: Remove roast from oven and transfer to a cutting board; tent loosely with foil and rest for 20 minutes.
  3. Step 3: Meanwhile, place roasting pan over medium heat on the stove. Add 8 oz sliced cremini mushrooms and sauté for 5 minutes until browned. Stir in 4 minced garlic cloves and cook for 1 minute until fragrant.
  4. Step 4: Sprinkle 2 tbsp all-purpose flour over mushrooms and stir for 1 minute to cook the flour. Slowly whisk in 1 cup beef broth and 2 tbsp soy sauce, scraping browned bits from the pan. Simmer for 5-7 minutes until gravy thickens and coats the back of a spoon.
  5. Step 5: Slice rib roast and serve with mushroom soy pan gravy spooned generously over the top.
