I've had several recipes for Raost Beef over the years, but this one is simple and works well for me.
1 4-pound top sirloin roast , fat trimmed to 1/4 inch thick
Salt and pepper
1 tablespoon vegetable oil
8 ounces white mushrooms , chopped
2 onions , chopped fine
1 carrot , peeled and chopped
1 celery rib , chopped
1 tablespoon tomato paste
4 garlic cloves , minced
1/4 cup all-purpose flour
1 cup red wine
4 cups low-sodium beef broth
1 teaspoon Worcestershire sauce
Pat roast dry with paper towels. Rub 2 teaspoons salt evenly over surface of meat. Cover with plastic wrap and refrigerate for at least 1 hour or up to 24 hours.
Adjust oven rack to lower-middle position and heat
oven to 275 degrees. Pat roast dry with paper towels and rub with 1 teaspoon pepper. Heat oil in large Dutch oven over medium-high heat until just smoking. Brown roast all over, 8 to 12 minutes, then transfer to V-rack set inside roasting pan (do not wipe out Dutch oven). Transfer to oven and cook until meat registers 125 degrees (for medium-rare), 1½ to 2 hours.
Meanwhile, add mushrooms to fat in Dutch oven and cook until golden, about 5 minutes. Stir in onions, carrot, and celery and cook until browned, 5 to 7 minutes. Stir in tomato paste, garlic, and flour and cook until fragrant, about 2 minutes. Stir in wine and broth, scraping up any browned bits with wooden spoon. Bring to boil, then reduce heat to medium and simmer until thickened, about 10 minutes. Strain gravy, then stir in Worcestershire and season with salt and pepper; cover and keep warm.
Transfer roast to cutting board, tent with foil, and let rest 20 minutes. Slice roast crosswise against grain into 1/2-inch-thick slices. Serve with gravy.
