Standing rib roast is a special event; it's also surprisingly easy to make. This version gets a spice rub and a rich, earthy sauce that can be largely made ahead. Ingredients:
1 well-trimmed 8- to 9-pound rib roast (with 4 bones) |
6 1/2 teaspoons crushed dried rosemary, divided |
1 tablespoon coarse kosher salt |
2 teaspoons freshly ground black pepper |
1/2 cup plus 2 tablespoons olive oil |
2 cups boiling water |
1 1/2 ounces dried porcini mushrooms |
4 tablespoons (1/2 stick) butter, room temperature, divided |
10 ounces fresh button mushrooms, cut into 1/4-inch-thick slices |
4 garlic cloves, minced |
2 tablespoons all purpose flour |
1 1/2 cups low-salt beef broth |
3/4 cup dry red wine |
2 bunches fresh rosemary (for garnish) |
Directions:
1. Place rib roast, fat side up, in heavy roasting pan. Mix 4 teaspoons crushed rosemary, salt, and pepper in small bowl. Stir in 1/2 cup oil. Rub mixture all over roast. DO AHEAD Can be made 1 day ahead. Cover and chill. Let stand at room temperature 45 minutes before roasting.
2. Combine 2 cups boiling water and porcini; let soak until mushrooms soften, about 20 minutes. Strain soaking liquid through fine strainer set over measuring cup; reserve porcini. If needed, add enough water to soaking liquid to measure 1 cup. Coarsely chop porcini.
3. Melt 2 tablespoons butter with remaining 2 tablespoons oil in large skillet over medium-high heat. Add fresh mushrooms; sauté until browned, about 6 minutes. Add porcini and garlic; stir 1 minute. Remove from heat. Combine flour, remaining 2 tablespoons butter, and remaining 2 1/2 teaspoons crushed rosemary in small bowl; mash with fork to smooth paste. DO AHEAD Porcini soaking liquid, mushroom mixture, and flour-butter mixture can be made 1 day ahead. Cover separately; chill.
4. Place rack in bottom third of oven and preheat to 350°F. Cook roast until instant-read thermometer inserted straight down into top center of roast registers 125°F to 130°F for medium-rare, about 2 hours 30 minutes.
5. Transfer roast to platter; cover loosely with foil and let rest 35 to 40 minutes. Skim any fat from top of pan juices (there will be a small amount of pan drippings); reserve juices in pan.
6. Set roasting pan atop 2 burners over medium-high heat. Add reserved 1 cup porcini soaking liquid, broth, and wine; bring to boil, scraping up any browned bits. Add mushroom mixture, then butter-flour mixture; whisk constantly over medium-high heat until sauce thickens, about 2 minutes. Season sauce to taste with salt and pepper.
7. Garnish roast on platter with fresh rosemary sprigs. Slice roast and serve, passing mushroom sauce separately.
