What temperature do you bake a meatloaf and au gratin potatoes in the same oven?

You can bake meatloaf and au gratin potatoes together at a temperature of 350°F (175°C). This temperature allows the meatloaf to cook thoroughly while giving the au gratin potatoes enough time to become golden and bubbly. Just ensure that the meatloaf reaches an internal temperature of 160°F (70°C) for safety. Adjust cooking times as necessary, possibly covering the au gratin if it browns too quickly.
