- 1/2 cup dried wakame seaweed (1/2 ounce)
- 1 cup boiling water
- 1 stick unsalted butter, at room temperature
- Kosher salt
- 1 1/4 pounds whole heads of maitake (also known as hen-of-the-woods) mushrooms
- 1/4 cup extra-virgin olive oil
- 2 tablespoons chopped chives
- Lemon wedges, for serving
How to make this recipe
In a small bowl, cover the seaweed with the boiling water and let stand until pliable, about 30 minutes. Drain and chop the seaweed; transfer to a bowl. Stir in the butter and season with salt and pepper.
Preheat the oven to 425°. Arrange the mushrooms on a rimmed baking sheet in a single layer. Drizzle with the olive oil, season generously with salt and pepper and toss to coat. Dollop three-fourths of the seaweed butter over the mushrooms. Roast for about 30 minutes, basting occasionally, until tender, deeply golden and crispy in spots.
Scrape the mushrooms and crispy seaweed onto a serving platter and top with the chives. Serve with lemon wedges and pass the remaining seaweed butter at the table.
The seaweed butter can be refrigerated for 1 week or frozen for up to 1 month.
The saltiness of these pretty mushrooms is a wonderful match for Albariño from coastal Spain.
