Preheat your oven to 375°F (190°C).
Grease a 12-cup muffin tin with butter or cooking spray.
Roll out the puff pastry on a lightly floured surface and cut into 12 equal squares.
Press each square into the muffin cups, ensuring the edges are slightly above the rim.
In a mixing bowl, whisk together the eggs and heavy cream until well combined.
Stir in the cheddar cheese, Parmesan cheese, and chopped herbs. Season with salt and pepper.
Pour the egg mixture evenly into each pastry-lined muffin cup.
Bake in the preheated oven for 20-25 minutes, or until the quiches are puffed and golden brown.
Remove from the oven and let cool slightly before serving.
Variations & Tips
For a different flavor profile, try adding cooked bacon or ham to the egg mixture. You can also experiment with different cheeses, such as Gruyère or feta, for a unique twist. If you prefer a crustless version, simply omit the puff pastry and bake the egg mixture directly in a well-greased muffin tin. For a gluten-free option, use gluten-free pastry or a crust made from almond flour.
