Crostini are little toasts with big flavor. This version piles on garlicky, buttery mushrooms with fresh thyme and Parmesan. One bite. That’s all it takes. Make extra. They’ll disappear.
Toast Bread
Preheat oven to 400°F (200°C).
Brush bread slices with olive oil. Toast 5-7 minutes until golden.
Rub warm toasts with garlic clove. Set aside.
Cook Mushrooms
Heat butter and olive oil in a large skillet over medium-high heat.
Add mushrooms in a single layer (don’t crowd). Cook 5-7 minutes without stirring too much until golden brown.
Add garlic and thyme. Cook 1 minute until fragrant.
Pour in wine (if using). Scrape up brown bits. Cook until evaporated.
Season
Stir in Parmesan. Season with salt and pepper.
Assemble
Pile mushrooms onto each toast. Drizzle with truffle oil if using.
Top with extra thyme or Parmesan.
Serve
Serve immediately while mushrooms are hot and bread is crisp.

Storage Notes
Don’t assemble ahead — soggy crostini are tragedy. Store mushroom mixture in fridge for 3 days. Reheat in a skillet. Toast bread fresh when ready to serve. Assemble at the last minute for maximum crunch.
