Ingredients
Scale
Bread and Topping
- 1 baguette (sliced into 1/2-inch rounds)
- 2 tablespoons olive oil
- 1 cup Gruyère cheese (shredded)
- Fresh parsley (chopped, for garnish)
Mushroom Mixture
- 2 tablespoons butter
- 1 shallot (finely chopped)
- 2 cloves garlic (minced)
- 12 ounces mixed mushrooms (cremini, shiitake, or button; sliced)
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
- Salt and black pepper to taste
- 1/4 cup dry white wine or broth
Instructions
- Preheat and Toast Bread: Preheat your oven to 375°F. Arrange the baguette slices on a baking sheet and brush them lightly with olive oil. Toast the slices in the oven for 8–10 minutes, flipping halfway through, until they are golden and crisp.
- Prepare Mushroom Mixture: While the bread is toasting, heat a large skillet over medium heat. Melt the butter along with the remaining olive oil in the skillet. Add the finely chopped shallot and cook for 2–3 minutes until softened. Stir in the minced garlic and cook for an additional 30 seconds to release its aroma.
- Sauté Mushrooms: Add the sliced mixed mushrooms, fresh thyme leaves, and season with salt and black pepper. Sauté the mixture for 8–10 minutes, stirring occasionally, until the mushrooms are golden and their moisture has evaporated.
- Deglaze Pan: Pour in the dry white wine or broth to deglaze the pan, scraping up any browned bits. Cook for about 2 more minutes until most of the liquid has been absorbed, then remove the skillet from heat.
- Assemble Crostini: Spoon the mushroom mixture generously onto each toasted baguette slice. Sprinkle shredded Gruyère cheese evenly over the top.
- Melt Cheese: Return the assembled crostini to the oven and bake for 5–7 minutes until the cheese is melted, bubbly, and slightly golden.
- Garnish and Serve: Remove from the oven and garnish each crostini with chopped fresh parsley. Serve warm for the best flavor and texture.
Notes
- For extra flavor, drizzle a small amount of truffle oil over the crostini just before serving.
- This recipe makes a fantastic appetizer for holiday gatherings, wine nights, or any casual party.
- You can substitute Gruyère with other melty cheeses like Emmental or Fontina if preferred.
- To keep the toast crispier, serve the crostini immediately after baking.
