- 2 tablespoons olive oil

Instructions
- Preheat Oven: Preheat your oven to 400°F (200°C) to prepare for toasting the baguette slices.
- Heat Olive Oil: In a skillet over medium heat, warm the olive oil to prepare for sautéing the vegetables.
- Caramelize Onions: Add the sliced onions to the skillet and cook them slowly for about 15 minutes until they become soft and caramelized, developing a rich, sweet flavor.
- Sauté Mushrooms: Stir in the sliced mushrooms and continue to cook for approximately 5 minutes until they soften and blend with the caramelized onions.

- Garnish and Serve: Sprinkle freshly chopped parsley on top and serve immediately for the best flavor and texture.
Notes
- Use day-old baguette for better toasting results.
- For a richer flavor, you can add a small amount of butter while caramelizing onions.
- Choose cremini or button mushrooms for the topping for a classic taste.
- Serve warm to enjoy the best texture and flavor contrast between crunchy bread and soft topping.
- These crostini can be prepared ahead by sautéing the topping and toasting the bread separately, then assembled just before serving.
