Recipe Information
Ingredients
- 2 sheets Puff pastry sheets
- 250 grams Button mushrooms
- 1 medium Yellow onion
- 1 teaspoon Fresh thyme
- 2 tablespoons Olive oil
- 1 tablespoon Butter
- 2 cloves Garlic
- 0.5 teaspoon Salt
- 0.25 teaspoon Freshly ground black pepper
- 50 grams Grated Parmesan cheese
- 1 large Egg
- 1 tablespoon Milk
Instructions
Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper.
Remove the puff pastry sheets from the freezer and allow them to thaw slightly on a clean surface.
Finely dice the mushrooms and onion. Mince the garlic.
Heat a large skillet over medium heat. Add olive oil and butter, then sauté the onion until soft and golden, about 5-7 minutes.
Add the mushrooms, garlic, fresh thyme, salt, and pepper to the skillet, and cook until the mushrooms release their moisture and most of it evaporates, around 5-6 minutes.
Remove the mushroom-onion mixture from the heat and let it cool slightly. Stir in the grated Parmesan cheese.
Cut the puff pastry sheets into 12 equal squares. Place each square on the lined baking tray, leaving a little space between each piece.
Using a small knife, lightly score a border about 1-2 cm from the edge of each puff pastry square, being careful not to cut all the way through.
Divide the mushroom-onion mixture evenly among the pastry squares, spreading it within the scored borders.
In a small bowl, whisk together the egg and milk to create an egg wash. Brush the edges of the pastry with the egg wash to ensure a golden, crisp finish.
Bake the tartlets in the preheated oven for 20-25 minutes, or until the pastry is puffed and golden brown.
Remove from the oven and let the tartlets cool for a few minutes before serving. Enjoy warm or at room temperature!
