Direction

1. Heat 2 tablespoons oil in a large cast-iron skillet over high just until smoking. Add one-third of the mushrooms in a single layer, and cook, without stirring, until golden brown, about 3 minutes. Stir in 3 thyme sprigs, 2 crushed garlic cloves, 1/4 teaspoon salt, and 1/4 teaspoon pepper. Reduce heat to medium-high, and cook, stirring occasionally, until mushrooms are tender and browned all over, about 3 minutes. Add 1 tablespoon butter, 1 tablespoon parsley, and 1 teaspoon vinegar. Cook, stirring occasionally, until mushrooms are coated in butter, about 1 minute. Transfer mushroom mixture to paper towels to drain; discard cooked garlic and thyme.
2. Wipe skillet clean, and repeat process 2 times with remaining oil, remaining mushrooms, remaining thyme, remaining garlic, 1/2 teaspoon salt, 1/2 teaspoon pepper, 2 tablespoons butter, remaining parsley, and remaining vinegar. Place all mushrooms in a large bowl,and season with remaining 1/2 teaspoon salt and remaining 1/4 teaspoon pepper. Keep warm or let cool to room temperature.
3. Preheat oven to 350°F. Place brioche slices in a single layer on a wire rack set inside a baking sheet. Bake in preheated oven until lightly toasted, about 8 minutes per side. Brush with remaining 2 tablespoons softened butter.
4. Spread cheese evenly over brioche toasts. Spoon mushroom mixture evenly over toasts; garnish with parsley, pickled onion slices, frisée, and chives. Drizzle with lemon juice and extra-virgin olive oil.
