Cooking Instructions:

Preheat your oven to 400°F (200°C). Prepare a baking sheet by lining it with parchment paper to prevent sticking.

In a mixing bowl, combine the mashed potatoes, shredded cheese, salt, pepper, and any additional seasonings you prefer. Mix well until all ingredients are fully incorporated.

Roll out the thawed puff pastry on a lightly floured surface to your desired thickness. Cut the pastry into squares (approximately 3x3 inches).

Place a tablespoon of the potato mixture in the center of each pastry square. Be careful not to overfill, as this can make sealing difficult.

Fold the pastry over the filling to create a triangle or rectangle shape. Pinch the edges firmly to seal them, making certain no filling escapes during baking.

Brush the tops of the potato puffs with the beaten egg for a golden finish. You can also make a small slit in the top of each puff to allow steam to escape.

Place the puffs on the prepared baking sheet and bake in the preheated oven for 20-25 minutes, or until they're golden brown and puffed up.

Once baked, remove the potato puffs from the oven and allow them to cool slightly before serving. Enjoy them warm!

Extra Tips:

When preparing potato puffs, feel free to experiment with different fillings and spices to suit your taste. You can add cooked bacon, sautéed onions, or even chopped vegetables to the potato mixture for added flavor and texture. Keeping puff pastry cold is essential for achieving the best puff when baking.

If you prefer a crispier texture, consider frying the puffs instead of baking them. Just make sure that the oil is hot enough before adding the puffs to achieve a perfectly crispy exterior. Enjoy your cooking experience!
