Mushroom Crostini Appetizers
Equipment
- 1 large baking sheet
- 1 large skillet
- 1 Cutting board
- 1 Chef's knife
- 1 Mixing bowl
- 1 Wooden spoon
- 1 pastry brush or spoon
- 1 measuring cup set
- 1 measuring spoon set
Ingredients
- 1 baguette loaf sliced into 1/2-inch rounds
- 3 tablespoon olive oil divided
- 2 tablespoon unsalted butter
- 16 ounce mushrooms finely sliced
- 2 clove garlic minced
- 1/4 teaspoon kosher salt
- 1/4 teaspoon black pepper freshly ground
- 1/4 teaspoon dried thyme or 1 teaspoon fresh thyme leaves
- 1/4 cup dry white wine or vegetable broth
- 1/4 cup grated Parmesan cheese
- 1/4 cup mascarpone cheese or cream cheese softened
- 2 tablespoon fresh parsley finely chopped
Instructions
- Preheat the oven to 400°F (200°C).
- Arrange the baguette slices on a large baking sheet in a single layer.
- Brush both sides of each slice lightly with 2 tablespoons of the olive oil.
- Toast the bread in the oven for 6–8 minutes, flipping halfway, until lightly golden and crisp, then set aside.
- Heat the remaining 1 tablespoon olive oil and the butter in a large skillet over medium-high heat.
- Add the sliced mushrooms to the skillet and cook, stirring occasionally, for 6–8 minutes until they release their moisture and start to brown.
- Stir in the minced garlic, salt, pepper, and thyme, and cook for 1–2 minutes until fragrant.
- Pour in the white wine or vegetable broth, scraping the bottom of the pan, and cook for 2–3 minutes until most of the liquid has evaporated.
- Reduce the heat to low, stir in the Parmesan and mascarpone (or cream cheese) until melted and creamy, then remove from the heat.
- Spoon a generous amount of the mushroom mixture onto each toasted baguette slice.
- Return the assembled crostini to the oven for 3–5 minutes to warm through and lightly set the topping.
- Remove from the oven and sprinkle with chopped fresh parsley before serving.
Notes
For best results, slice the baguette just before toasting so it stays fresh and doesn’t dry out too much, and cook the mushrooms in a wide skillet so they sauté and brown instead of steaming. Let the pan get hot before adding the mushrooms, and avoid overcrowding to develop deep flavor; if needed, cook them in two batches. You can prepare the mushroom topping a few hours ahead and gently rewarm it, then toast the bread just before serving to keep it crisp. Vary the flavor by mixing mushroom types (cremini, shiitake, oyster), adding a pinch of red pepper flakes for heat, or finishing with a drizzle of good olive oil or a few drops of balsamic glaze for extra richness.
