A simple drizzle of olive oil on the mushrooms helps them cook through and stay moist and tender.

You can bake these directly on the baking sheet, but I wanted the bottoms of the portabello mushrooms to cook evenly. Simply elevate them by cooking on a wire rack. The air in the oven will be able to move under and around the mushrooms during baking.
