Table of Contents
Ingredients You’ll Need
- 1 sheet puff pastry – thawed but kept cold for best puff and crispness
- 1 salmon fillet (12–14 oz, center-cut) – skin removed, patted very dry so the pastry stays crisp
- 2 tablespoons unsalted butter – for sautéing the aromatics
- 2 cloves garlic, finely chopped – adds a gentle aromatic base
- ½ medium yellow onion, finely chopped – brings sweetness once sautéed
- 5 oz fresh baby spinach, roughly chopped – wilts quickly and blends well into the filling
- ⅓ cup plain breadcrumbs – helps absorb moisture and keep filling firm
- 4 oz cream cheese, softened – gives the filling a creamy texture
- ¼ cup grated Parmesan cheese – adds nutty depth and saltiness
- 2 tablespoons fresh dill, chopped – classic pairing with salmon
- 1 teaspoon Dijon mustard (optional) – brightens the flavor of both fish and filling
- 1 egg, beaten with 1 teaspoon water – for a shiny egg wash finish
- Kosher salt and freshly ground black pepper – to season salmon and filling
- Lemon wedges, for serving – a squeeze of freshness at the table
Step-by-Step Instructions
Step 1: Preheat the oven and prepare the baking sheet
Set your oven to 425°F (220°C). Line a large baking sheet with parchment paper and, if you’d like an extra-crisp bottom, place the sheet in the oven to preheat.
Step 2: Cook the spinach filling
Melt the butter in a skillet over medium heat. Add the onion and garlic and sauté until translucent, about 3–5 minutes. Stir in the spinach and cook just until wilted, about 1 minute.
Remove from heat, then stir in the breadcrumbs, cream cheese, Parmesan, dill, and optional Dijon mustard. Season lightly with salt and pepper. Let the mixture cool completely before using.
Step 3: Season the salmon
Pat the salmon fillet very dry with paper towels. Sprinkle both sides with salt and black pepper. If using, spread a thin layer of Dijon mustard on top of the fillet for extra flavor.
Step 4: Assemble the Wellington
On a lightly floured surface, roll the puff pastry just enough to smooth the seams. Place the salmon fillet in the center, then spoon the spinach mixture evenly over the top, leaving about a 1-inch border around the edges.
Step 5: Fold and seal the pastry
Bring the long sides of the pastry up and over the salmon, then fold the shorter ends over like a present. Trim away any excess pastry and press gently to seal. Carefully flip the package seam-side down onto the prepared baking sheet.
Step 6: Add egg wash and score the top
Brush the entire pastry with the beaten egg wash. Use a sharp knife to score diagonal lines across the top, this helps release steam while baking and adds a pretty finish.
Step 7: Bake until golden
Bake for 20–25 minutes, or until the pastry is deep golden brown and crisp. The salmon should reach an internal temperature of 125–130°F (52–54°C) for medium doneness.
Step 8: Rest and serve
Let the salmon wellington rest for 10 minutes before slicing. Use a serrated knife with a gentle sawing motion to avoid crushing the pastry. Serve with lemon wedges for brightness.

Pro Tips
- Cool the filling before wrapping. A hot spinach mixture will melt the pastry before it bakes, leading to soggy layers. Let it cool fully for best results.
- Chill before baking. Once wrapped, place the assembled salmon wellington in the fridge for 10 minutes. Cold pastry puffs better and holds its shape in the oven.
- Slice with care. Use a sharp serrated knife and a gentle sawing motion to cut clean slices without crushing the flaky crust.
