High heat is the only way to roast mushrooms without boiling them in their own moisture. When mushrooms hit a 450 degree F oven packed tightly together, they steam slightly at first, then rapidly release internal water that evaporates off the hot pan surface rather than pooling around the caps. Managing moisture and cheese placement prevents common texture failures.
Reserve the trimmed stems in a sealed container in the refrigerator for up to three days to use in vegetable stocks or blended soups. Proper oven calibration guarantees the parmesan crisps instead of melting into an oily puddle.
