The Caramelized Onion: A Sweet and Savory Base

The foundation of these hand pies is the caramelized onion. Onions, when cooked slowly over low heat, release their natural sugars, transforming into a sweet, tender component that adds depth to the overall flavor of the dish. The addition of sugar and salt during the caramelization process enhances this natural sweetness, allowing the onions to develop a golden-brown color and a rich flavor.

To caramelize the onions, start by heating a skillet over medium-high heat and adding a mixture of butter and olive oil. The butter adds richness, while the olive oil helps to prevent the butter from burning. Once the onions are added, cook them for about 20 minutes, stirring frequently, until they are soft, sweet, and golden brown. Allow the onions to cool completely before incorporating them into the filling.

The Mushroom Filling: Earthy and Flavorful

The mushroom filling is the heart of these hand pies, bringing a savory, umami-packed element to the dish. Mushrooms, particularly varieties like cremini or button mushrooms, have a naturally rich flavor that pairs perfectly with the sweetness of the caramelized onions. Sautéing the mushrooms in the same pan as the onions allows their flavors to meld together, creating a harmonious filling.

Start by cooking the mushrooms in a hot skillet until they release their moisture and shrink down. Stir frequently for about 10-15 minutes, allowing the mushrooms to brown and develop a deeper flavor. Adding garlic, thyme, soy sauce, salt, and freshly ground black pepper during the last few minutes of cooking enhances the savory flavor profile of the mushrooms. The soy sauce adds a touch of umami and depth, making the filling even more flavorful. Once the mushroom mixture is cooked, remove it from the heat and let it cool completely before adding it to the pastry.

Assembling the Hand Pies: Easy and Delicious

Assembling the hand pies is a simple yet satisfying process. Start by preheating the oven to 400ºF (200ºC) and lining a baking sheet with parchment paper to prevent sticking. Roll out the puff pastry sheet and cut it into 6 equal squares. Each square will become an individual hand pie, so be sure to cut the pastry evenly to ensure each pie is a similar size.

Next, divide the grated cheese (cheddar or Gruyère) evenly between the pastry squares. The cheese will melt into the filling, adding richness and flavor. Then, spoon the caramelized onion and mushroom mixture onto each pastry square, ensuring the filling is spread evenly. Be sure to leave a border around the edges to make sealing the pies easier.

Brush the edges of the pastry with a beaten egg to help seal the pies and create a golden crust. Fold the pastry over the filling to form a half-moon shape, and press the edges together using a fork to create a crimped edge. The fork will also help to ensure that the hand pies are properly sealed, preventing the filling from spilling out during baking.

Baking the Hand Pies: Golden Perfection

Once assembled, place the hand pies on the prepared baking sheet and brush them with more beaten egg. This egg wash gives the hand pies a beautiful golden color once baked. Sprinkle a little grated Parmesan cheese on top for an extra burst of flavor and a delicious, crispy finish.

Bake the hand pies in the preheated oven for 15-20 minutes, or until the pastry is golden brown and crisp. The filling should be hot and melted, and the crust should be flaky and buttery. Once baked, allow the hand pies to cool slightly before serving. This will help the filling set and prevent any steam from escaping when you take a bite.
