The ultimate special occasion recipe! A classic bone-in Ribeye Roast gets an impressive finishing sauce and kicked up side dish.
Heat oven to 350°F. Combine seasoning ingredients; press evenly onto all surface of beef roast.
Place roast, fat side up, in shallow roasting pan. Insert ovenproof meat thermometer so tip is centered in thickest part of beef, not resting in fat or touching bone. Do not add water or cover. Roast in 350°F oven 2-1/4 to 2-1/2 hours for medium rare; 2-1/2 to 3 hours for medium doneness.
Meanwhile prepare Chocolate-Port Sauce. Melt butter in large nonstick skillet over medium heat. Add shallots and thyme; cook and stir 4 to 6 minutes or until shallots are lightly browned. Add port; cook 5 to 7 minutes or until reduced by one half, stirring occasionally. Add broth; bring to a boil. Reduce heat to medium; cook 15 to 17 minutes or until reduced by one half, stirring occasionally. Stir in cream and soy sauce; cook 3 to 5 minutes or until slightly thickened, stirring frequently. Remove from heat. Add chocolate; stir until melted. Season with salt and pepper, as desired. Keep warm.
About 45 minutes before serving, prepare Goat Cheese Mashed Potatoes.
Remove roast when meat thermometer registers 135°F for medium rare; 145°F for medium. Transfer roast to carving board; tent loosely with aluminum foil. Let stand 15 to 20 minutes. (Temperature will continue to rise about 10°-15°F to reach 145°F for medium rare; 160°F for medium.)
Carve roast into slices; season with salt, as desired. Serve with sauce and mashed potatoes. Garnish with parsley, if desired.
Goat Cheese Mashed Potatoes: Peel 3-1/2 pounds all-purpose potatoes and cut into 2-inch pieces. Place potatoes in stockpot and add enough water to cover potatoes; add salt as desired. Bring water to a boil. Reduce heat; cover and cook 25 to 30 minutes or until potatoes are tender. Drain well. Mash potatoes with 1-1/2 cups milk, 6 ounces softened goat cheese and 2 tablespoons butter in large bowl with electric mixer until smooth. Season with 1-1/2 teaspoons salt and pepper, as desired. Keep warm.
Test Kitchen Tips Sauce may be prepared up to 1 day ahead. Cover and refrigerate. Reheat gently before serving. Do not boil.
To prevent seasoning on roast from overbrowning, tent loosely with aluminum foil after roasting for 1 hour.
