The secret to this recipe lies in the contrast of textures—the crunch of the oven-baked bread against the tender, buttery mushrooms. By rubbing the warm toast with a fresh garlic clove, you infuse the bread with a fragrant aroma that perfectly complements the topping.

Ingredients

  • Bread & Garlic: 1 baguette (sliced into 8 diagonal pieces), 2 tablespoons olive oil, 2 large garlic cloves (one whole, one minced).
  • Mushrooms: 300 g mixed wild mushrooms (cremini, shiitake, oyster), 1 tablespoon unsalted butter, 1 tablespoon olive oil, 1 small shallot (finely chopped), 1 teaspoon fresh thyme leaves, salt and freshly ground black pepper.
  • To Finish: 30 g Parmesan cheese (shaved), fresh thyme sprigs.

Instructions

Step 1
Preheat your oven to 200°C (400°F).
Step 2
Arrange the baguette slices on a baking sheet and brush both sides with 2 tablespoons of olive oil. Bake for 8–10 minutes, turning once, until golden.
Step 3
While the toasts are still warm, rub one side of each with the whole peeled garlic clove, then set them aside.
Step 4
In a large skillet, heat 1 tablespoon of olive oil and 1 tablespoon of butter over medium-high heat. Sauté the shallot for 1 minute, then add the minced garlic for 30 seconds.
Step 5
Add the sliced mushrooms and season with salt and pepper. Cook for 5–7 minutes until golden and any liquid has evaporated. Stir in the thyme leaves.
Step 6
Spoon the mushroom mixture onto the toasts, top with shaved Parmesan and extra thyme, and serve warm.

Zusatztipps für die Zubereitung

To achieve the best texture, ensure the skillet is hot before adding the mushrooms so they sear and brown rather than steaming in their own moisture. Don't skip rubbing the whole garlic clove on the warm bread; it provides a much more delicate and even garlic flavor than using garlic powder.

Varianten und Anpassungen

This recipe is easily adaptable. For a vegan version, simply omit the Parmesan or use a plant-based alternative, and replace the butter with additional olive oil. For those with gluten sensitivities, use a high-quality gluten-free baguette.

Serviervorschläge

These crostini are best enjoyed immediately while warm. They pair beautifully with a crisp white wine such as Sauvignon Blanc or Pinot Grigio, which cuts through the richness of the sautéed mushrooms and butter.
