Preheat oven to 350 degrees F. Season beef all over with 2 tablespoons rosemary, salt, and pepper. Heat oil in a 12-inch skillet over medium-high heat. Brown roast well on all sides. Remove to a rack set in a roasting pan. Roast for 1 hour 30 minutes to 1 hour 45 minutes or until 135 degrees F. Remove from oven. Cover with foil and let stand 15 minutes. Serve with Rosemary Olives and additional fresh rosemary, if desired.
In a large skillet, warm the olives, garlic, and herbs in the oil over medium heat for 3 to 5 minutes or until warmed through and herbs begin to sizzle a bit, swirling and tossing occasionally to avoid browning the garlic. Season will with salt, black pepper, and Aleppo pepper. Cook 1 minute more. Serve warm spooned over roast beef.
