Zusatztipps für die Zubereitung

To achieve the best texture, ensure your skillet is large enough so the mushrooms aren't crowded; this allows them to brown properly rather than steaming. Using a cheese shaver or vegetable peeler will give you the perfect thin ribbons of Parmesan cheese.

Varianten und Anpassungen

You can substitute the wild mushrooms with any combination you have available. For a vegan version, simply omit the Parmesan or use a plant-based alternative, and replace the butter with additional olive oil. For gluten-free needs, use a gluten-free baguette.

Serviervorschläge

These crostini pair beautifully with a crisp white wine such as Sauvignon Blanc or Pinot Grigio. Serve them immediately while the bread is crisp and the mushrooms are hot for the best experience.
