Ingredients List
Let’s talk about flavor and texture: flaky pastry, rich salmon, and garlicky creamy spinach, all in one bite. Here’s everything you need:
Main Ingredients:
- 1 sheet puff pastry, thawed (store-bought is perfect; use all-butter for best flavor)
- 4 skinless salmon fillets (about 6 oz each)
- 1 tablespoon Dijon mustard (adds tang and depth)
- 1 tablespoon olive oil
- 1 small onion, finely chopped
- 2 garlic cloves, minced
- 1 pound fresh spinach (or use 10 oz frozen, thawed and drained)
- ½ cup white wine (Sauvignon Blanc or dry white works best)
- ¼ cup heavy cream
- Salt and black pepper, to taste
- 1 egg, beaten (for egg wash)
- Fresh dill or parsley, for garnish (optional)
Substitution Ideas:
- Replace salmon with halibut or cod for a milder taste.
- Use leeks or shallots instead of onion for a sweeter, milder profile.
- Swap white wine with vegetable broth for an alcohol-free version.
- For dairy-free, sub cream with coconut cream or unsweetened oat cream.

Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Pro Tip: Preheating the baking sheet helps the bottom of the pastry cook evenly and stay crisp.
Step 2: Season the Salmon
Pat the salmon fillets dry. Season both sides with salt and pepper, then brush the top with Dijon mustard. Set aside.
Step 3: Make the Creamy Garlic Spinach
Heat olive oil in a skillet over medium heat. Add onions and cook until translucent, about 3 minutes. Stir in minced garlic.
Add spinach and sauté until wilted. Pour in white wine, cooking until reduced by half. Stir in the heavy cream and simmer until slightly thickened. Season with salt and pepper to taste.
Personal Tip: Let the filling cool completely before assembling to avoid soggy pastry.
Step 4: Assemble the Wellington
Roll out the puff pastry on a floured surface. Cut into 4 equal rectangles.
Place a spoonful of spinach mixture on each rectangle. Lay the salmon (mustard side down) over the filling. Add more spinach on top.
Fold the pastry over the salmon and seal the edges. Place seam-side down on the baking sheet. Use a fork to crimp the edges for a decorative touch.
Step 5: Add the Golden Finish
Brush each pastry with the beaten egg for a glossy golden crust. Optional: score a decorative pattern on the top with a sharp knife (don’t cut through).
Step 6: Bake to Perfection
Bake for 25–30 minutes or until the pastry is golden and the salmon is just cooked through.
Remove from oven and let rest for 5 minutes before serving. Garnish with fresh dill or chopped parsley.
