Question: how long does it take to cook a 1.5 lb roast?
Answer: Drizzle with olive oil and place the roast on top. Place the roast in the oven and bake for about 15 minutes, then reduce the heat to 375 F (190 C). Roast for about 13-15 minutes per pound for rare, 17-19 minutes for medium, and 22-25 for cooked through.
