Pro Tips for the Best Ham and Cheese Puff Pastry

Thaw the puff pastry overnight. It is easier to work with and puffs better.
Keep the pastry cold. Cold pastry puffs better, so work quickly.
Don’t overfill the pastry. Too much filling can leak out during baking.
Seal the edges well. This prevents the filling from escaping.
Brush with egg wash. This creates a beautiful, golden finish.
Bake until deep golden brown. This ensures the pastry is fully cooked.
Let it cool slightly before slicing. A 3 to 5 minute rest allows the cheese to set.
Serve warm. This is best enjoyed hot and fresh.
