Martha roasts crispy shiitake mushrooms for a healthy snack or side dish.
Preheat oven to 400 degrees.
Place mushroom caps on a baking sheet, gill-side up. Drizzle with 2 tablespoons olive oil, turn mushrooms, and drizzle with remaining 2 tablespoons olive oil; season with salt and pepper and toss to coat.
Transfer to oven and roast for 25 minutes. Turn mushrooms and continue to roast until larger mushrooms are crisp on the edges and smaller ones are crisp throughout, 10 to 15 minutes more. Season with more salt; serve warm or at room temperature.
