Mushroom Crostini is an elegant and easy appetizer—crispy, golden baguette slices topped with savory, garlicky sautéed mushrooms, fresh thyme, and a drizzle of balsamic glaze. Perfect for parties, holiday gatherings, or a simple snack.
Instructions
Make the Crostini
Preheat oven to 375°F (190°C). Arrange baguette slices on a baking sheet. Brush both sides with olive oil. Bake for 8 to 10 minutes until golden and crisp. Set aside.
Sauté the Mushrooms
Heat olive oil in a large skillet over medium-high heat. Add mushrooms in a single layer (work in batches if needed). Cook undisturbed for 3 to 4 minutes until golden brown. Stir and continue cooking for another 3 to 4 minutes until caramelized.
Add Aromatics
Add shallot and garlic to the skillet. Cook for 1 to 2 minutes until fragrant. Add thyme and balsamic vinegar. Cook for 1 minute until vinegar has mostly evaporated. Season with salt and pepper. Stir in fresh parsley.
Assemble the Crostini
Top each toasted baguette slice with a generous spoonful of sautéed mushrooms.
Garnish and Serve
Drizzle with balsamic glaze and garnish with fresh thyme sprigs. Serve immediately.
Pro-Tips for Picture-Perfect Mushroom Crostini
- Don’t Overcrowd the Pan: Mushrooms need space to brown properly.
- Use a Mix of Mushrooms: Cremini, shiitake, and oyster mushrooms add depth.
- Toast Crostini Until Crisp: Prevents sogginess.
- Serve Immediately: Best when the bread is still crisp.
These Mushroom Crostini are savory, earthy, and elegant—a perfect party appetizer.
