Instructions

1. Preheat oven to 425°F. Grate 1 tablespoon peel and squeeze 1 tablespoon juice from 1 lemon. Combine lemon peel, lemon juice, garlic and pepper in small bowl; reserve 1 tablespoon for potatoes. Press remaining lemon mixture onto all surfaces of beef roast. Cut remaining lemon into 12 wedges lengthwise; set aside.
2. Place roast on rack in shallow roasting pan. Do not add water or cover; set aside.
3. Combine reserved 1 tablespoon lemon mixture, potatoes, lemon wedges, oil and 1/2 teaspoon salt on rimmed sheet pan; toss to coat evenly. Roast beef in 425°F oven 30 to 40 minutes for medium rare; 40 to 45 minutes for medium doneness. Roast potatoes 25 to 30 minutes or until potatoes are tender, stirring once.
4. Remove roast when instant-read thermometer registers 135°F for medium rare; 150°F for medium. Transfer to roast to carving board; tent loosely with aluminum foil. Let stand 15 minutes. (Temperature will continue to rise about 10°F to reach 145°F for medium rare; 160°F for medium.)
5. Carve roast across the grain into slices; season with salt, as desired. Serve with potatoes and lemon wedges.
