Description
Golden, flaky, and filled with savory sautéed mushrooms and caramelized onions, these Mushroom Puff Pastry Tarts are the perfect elegant appetizer or snack. Topped with melted Gruyère and a hint of thyme, they’re as delicious as they are beautiful.
Ingredients
- Puff Pastry Sheets: 2 sheets, thawed
- Cremini Mushrooms: 3 cups, sliced
- Yellow Onion: 1 large, thinly sliced
- Garlic: 2 cloves, minced
- Olive Oil: 2 tablespoons
- Fresh Thyme: 2 teaspoons, chopped
- Salt: 1 teaspoon
- Black Pepper: ½ teaspoon
- Gruyère Cheese: 1 cup, shredded
- Egg: 1, beaten (for egg wash)
Instructions
- Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
- In a frying pan, heat olive oil over medium heat. Sauté the onions until caramelized, about 10 minutes. Add garlic, then mushrooms, thyme, salt, and pepper. Cook until all moisture evaporates and the mixture is golden.
- Roll out the puff pastry on a floured surface. Cut each sheet into 4 equal rectangles and place them on the baking sheet.
- Score a 1 cm border around each piece. Spoon the mushroom mixture into the center of each, then sprinkle with Gruyère cheese.
- Brush the pastry borders with beaten egg for a golden finish.
- Chill tarts in the fridge for 10 minutes, then bake for 20 to 25 minutes until puffed and golden.
- Garnish with fresh thyme and serve warm or at room temperature.
Notes
- Make sure the mushroom filling is dry to avoid soggy pastry.
- Use parchment paper for easy removal and cleanup.
- Reheat in the oven to revive crispiness.
