Roasted mushrooms bring a delicious umami flavor to any dish and can easily stand in for meat in lots of recipes. So having a big batch on hand gives you freedom to riff all week. Don't worry about overcrowding the pan. As the mushrooms cook, they will release all their water, shrink and then finally crisp up in the olive oil. To keep this recipe versatile, we seasoned with only salt and pepper -- but chopped garlic or shallots and fresh herbs like thyme or rosemary are delicious additions.
