Equipment

  • 1 Baking sheet
  • 1 large skillet
  • 1 Cutting board
  • 1 Chef's knife
  • 1 Mixing bowl
  • 1 Wooden spoon
  • 1 pastry brush or spoon
  • 1 garlic press (optional)

Ingredients
  

  • 1 baguette loaf sliced into 1.25 centimeter thick rounds
  • 60 milliliter olive oil plus extra for drizzling
  • 30 gram unsalted butter
  • 400 gram mixed mushrooms sliced
  • 2 clove garlic minced
  • 60 milliliter dry white wine or vegetable broth
  • 2 gram kosher salt
  • 1 gram freshly ground black pepper
  • 5 gram fresh thyme leaves chopped
  • 10 gram fresh parsley chopped
  • 30 gram grated Parmesan cheese
  • 60 gram soft goat cheese or mascarpone optional; softened

Instructions
 

  • Preheat the oven to 200 degrees Celsius and line a baking sheet with parchment paper.
  • Arrange the baguette slices on the baking sheet in a single layer and brush the tops lightly with olive oil.
  • Toast the baguette slices in the oven for 7 to 9 minutes until lightly golden and crisp around the edges, then set aside.
  • While the bread toasts, heat olive oil and butter in a large skillet over medium-high heat until the butter is melted and foamy.
  • Add the sliced mushrooms to the skillet in an even layer and cook without stirring for 2 to 3 minutes to allow them to brown.
  • Stir the mushrooms, then continue cooking for 5 to 7 minutes until they release their moisture and it mostly evaporates.
  • Add the minced garlic, salt, pepper, and thyme to the mushrooms and cook for 1 to 2 minutes until fragrant.
  • Pour in the white wine or vegetable broth and cook for 2 to 3 minutes, scraping the bottom of the pan, until most of the liquid has reduced.
  • Remove the skillet from the heat and stir in half of the chopped parsley and the grated Parmesan cheese.
  • If using goat cheese or mascarpone, spread a thin layer onto each warm crostini.
  • Spoon a generous amount of the mushroom mixture onto each toasted baguette slice.
  • Transfer the mushroom crostini to a serving platter, drizzle lightly with olive oil, and sprinkle with the remaining parsley before serving.

Notes

Extra Tips For the best flavor, use a mix of mushrooms such as cremini, shiitake, and oyster, and avoid overcrowding the pan so they brown instead of steam. Day-old baguette works especially well because it toasts up crisp without becoming tough. You can toast the crostini in advance and re-crisp them in a hot oven for a few minutes just before topping. Adjust the garlic and herbs to your taste and feel free to add a pinch of red pepper flakes for gentle heat. If serving for a party, keep the mushroom topping warm in a covered pan over low heat and assemble crostini in small batches so the bread stays crunchy and the topping stays juicy.
