Ingredients

  • 1 medium loaf Baguette
  • 12 ounces, fresh Cremini Mushrooms
  • 2 cloves, minced Garlic
  • 1 medium, finely diced Shallot
  • 2 tablespoons Unsalted Butter
  • 1 tablespoon Olive Oil
  • 1 teaspoon, chopped Fresh Thyme
  • 2 tablespoons, chopped Fresh Parsley
  • 2 tablespoons Dry White Wine (optional)
  • 2 tablespoons, softened Cream Cheese (or mascarpone/crème fraîche)
  • 2 tablespoons, grated Parmesan Cheese (optional, for garnish)
  • 0.5 teaspoon Salt
  • 0.25 teaspoon, freshly ground Black Pepper

Instructions

  1. 1

    Preheat oven to 375°F (190°C). Slice the baguette into ½-inch thick rounds.

  2. 2

    Arrange baguette slices on a baking sheet. Drizzle lightly with olive oil and toast in the oven for 8-10 minutes, or until golden and crisp. Set aside.

  3. 3

    Clean the mushrooms thoroughly and slice them thinly.

  4. 4

    In a large skillet, melt butter with olive oil over medium heat. Add diced shallot and cook for 2-3 minutes until softened.

  5. 5

    Add minced garlic and sauté for 1 minute until fragrant. Add sliced mushrooms and cook for 8-10 minutes, stirring occasionally, until they release their liquid and start to brown.

  6. 6

    Deglaze the pan with dry white wine (if using), scraping up any browned bits from the bottom. Cook until the wine has evaporated.

  7. 7

    Stir in chopped fresh thyme, salt, and pepper. Remove from heat and stir in softened cream cheese (if using) and fresh parsley.

  8. 8

    Spoon the mushroom mixture generously onto each toasted baguette slice.

  9. 9

    Serve immediately, optionally garnished with a sprinkle of grated Parmesan cheese.

Chef's Tips

  • Storage: Leftover mushroom topping can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently before serving on freshly toasted crostini.
  • Substitutions: Feel free to experiment with different mushroom varieties like shiitake or oyster mushrooms. For a dairy-free version, omit the butter and cream cheese, using only olive oil, and consider a splash of vegetable broth for richness.
  • Make Ahead: Toast the baguette slices up to a day in advance and store them in an airtight container. Prepare the mushroom mixture a few hours ahead and gently reheat before assembling.
  • Fun Fact: While traditionally made with baguette, crostini can also be made with slices of rustic sourdough bread for a chewier texture and tangier flavor.
