Equipment

  • 1 Baking sheet
  • 1 Parchment paper
  • 1 Pastry brush
  • 1 Sharp knife
  • 1 Air fryer for quick version

Ingredients
  

  • 1 sheet puff pastry thawed
  • 1 lb 450 g salmon fillet skin removed
  • 2 tbsp olive oil
  • 1 small shallot finely chopped
  • 2 cups fresh spinach
  • 3 oz 85 g cream cheese, softened
  • 1 tsp Dijon mustard
  • 1 tbsp fresh dill or parsley chopped
  • 1 egg beaten (for egg wash)
  • Salt and black pepper to taste

Instructions
 

  • Prepare Filling: Heat olive oil in a pan, sauté shallot until soft. Add spinach and cook until wilted. Let cool slightly, then stir in cream cheese, Dijon mustard, and herbs. Season with salt and pepper.
  • Prepare Puff Pastry: Roll out puff pastry on parchment paper. Place salmon fillet in the center, season with salt and pepper. Spread spinach mixture evenly over salmon.
  • Wrap Salmon: Fold puff pastry over salmon, sealing edges tightly. Place seam-side down on a parchment-lined baking sheet.
  • 4. Egg Wash & Bake: Brush pastry with beaten egg for shine. Score lightly on top for design if desired. Bake at 400°F (200°C) for 25–30 minutes, until pastry is golden and salmon reaches 125–130°F (52–54°C) inside.
  • Serve: Slice and serve warm with a side salad or roasted vegetables.

Notes

  • For a richer filling, add sautéed mushrooms or a layer of smoked salmon.
  • Ensure puff pastry is well sealed to prevent leaks.
  • For a quick version, bake in an air fryer at 375°F (190°C) for 12–15 minutes.
  • Best served immediately but can be reheated in the oven to re-crisp pastry.
