- Make the filling: Add the cream cheese to the spinach and stir until melted. then mix in the parmesan cheese and lemon juice. Remove from heat and let it cool slightly.
- Assemble the pastry: Place the puff pastry on the baking sheet. Spoon the spinach mixture into the center, shaped about the same size as the salmon.
- Add the salmon: Season the salmon fillet with salt and pepper, then lay it on top of the spinach filling.
- Wrap and seal: Fold the puff pastry over the salmon, sealing all the edges. Gently flip it over so the seam is on the bottom.
- Brush and score: Brush the top and sides of the pastry with egg wash. Lightly score the top with a knife to let steam escape.

Recipe Tips:
- Pat the salmon dry before using: Wet salmon can make the pastry soggy. Use a paper towel to gently dry the fillet before wrapping it.
- Let the spinach filling cool before assembling: If the filling is too hot, it can melt the pastry and make it hard to work with. Give it a few minutes to cool down.
- Don’t roll the pastry too thin: Keep the puff pastry at its original thickness so it bakes up golden and crisp without tearing.
- Seal the edges well: Press the pastry edges firmly together to lock in the filling. This helps prevent any leaks in the oven.
- Use a sharp knife to score the top: Scoring allows steam to escape and gives a beautiful finish. Just make sure not to cut all the way through the pastry.
