For dinner this evening we are cooking a roast beef and intend to serve a baked brie appetizer. Unfortunately, we only have one oven. To reach medium rare the roast needs 3 hours at 325° while the brie needs to be cooked at 400° for 20 minutes.
Is there a way to cook both of these items in the oven at the same time? Is it a matter of adjusting the length of time the brie needs to be in the oven?
