Description
Crisp toasted baguette topped with sautéed earthy mushrooms and melted nutty Gruyère, finished with fresh herbs for a warm, elegant appetizer that’s easy to make and impossible to resist.
Ingredients
- Baguette: 1 loaf, sliced into 1/2-inch rounds
- Olive Oil: 2 tablespoons, for brushing the bread
- Mushrooms: 8 ounces, cremini or button, sliced thin
- Butter: 1 tablespoon, to sauté the mushrooms
- Garlic: 2 cloves, minced
- Fresh Thyme: 1 teaspoon, chopped
- Salt and Pepper: To taste
- Gruyère Cheese: 1 cup, freshly grated
- Parsley: 2 tablespoons, finely chopped, for garnish
Instructions
- Preheat Your Equipment: Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.
- Combine Ingredients: In a skillet over medium heat, melt butter with a splash of olive oil. Add sliced mushrooms and cook until golden, about 6 to 8 minutes. Stir in minced garlic, chopped thyme, salt, and pepper and cook for another minute.
- Prepare Your Cooking Vessel: Arrange baguette slices on the prepared baking sheet and brush each slice with olive oil. Toast in the oven for about 5 minutes until lightly golden.
- Assemble the Dish: Spoon the sautéed mushroom mixture onto each toasted baguette slice, distributing evenly.
- Cook to Perfection: Sprinkle freshly grated Gruyère over the mushroom-topped toasts and return the baking sheet to the oven for 5 to 7 minutes, until the cheese is melted and bubbling.
- Finishing Touches: Remove crostini from the oven, sprinkle with finely chopped parsley, and let cool for a minute so the cheese sets slightly.
- Serve and Enjoy: Arrange the crostini on a platter and serve warm as an appetizer or snack. Enjoy immediately for best texture.
Notes
- Toast the bread before topping to avoid soggy crostini.
- Do not overcrowd the pan when sautéing mushrooms so they brown instead of steaming.
- Use freshly grated Gruyère for a smoother, more even melt.
- You can prepare the mushroom mixture up to one day ahead and reheat before assembling.
