Meaty cremini mushrooms are tossed in a simple dressing of red wine vinegar, dijon mustard, olive oil, minced garlic, and chopped rosemary, then placed into a hot oven until tender. As they roast, the spongy mushrooms not only absorb the sharp and herbaceous flavors of the dressing, but their own meaty mushroom flavor intensifies as well.
After removing the mushrooms from the oven, they can be served warm or at room temperature. But if your guests have enough wine in them, they might not want to wait that long. In that case, just pass out the forks and let your guests dig in.
- 4 medium garlic cloves, minced (about 4 teaspoons)
- 1 tablespoon minced fresh rosemary
- 1/4 cup red wine vinegar
- 1 tablespoon dijon mustard
- 1/8 teaspoon dried red pepper flakes
- 1/2 teaspoon salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper, plus more to taste
- 1/2 cup olive oil
- 2 pounds crimini mushrooms, wiped clean
- 1 tablespoon lemon juice from 1 lemon
- Chopped fresh parsley, for garnish
Adjust oven rack to center position and preheat the oven to 400°F.
In a large bowl, add the garlic, rosemary, red wine vinegar, mustard, red pepper flakes, 1/2 teaspoon salt, and 1/2 teaspoon pepper and whisk until well combined. Slowly drizzle in the olive oil, while constantly whisking, and mix until the dressing thickens and emulsifies. Add the mushrooms to the bowl and toss until all the mushrooms are coated in the dressing.
Pour the dressing and the mushrooms into a large baking dish and arrange the mushrooms in a single layer. Place the mushrooms in the oven and roast for 15 minutes. Using a wooden spoon, stir the mushrooms, then continue roasting until the mushrooms are tender, about 10 minutes longer.
Allow the mushrooms to cool slightly. Transfer the mushrooms to a large serving dish, then stir in the lemon juice. Season to taste with more salt and pepper, and garnish with chopped parsley. Serve the mushrooms warm, or at room temperature, with crusty bread for dipping into the extra dressing.
