Ingredients

For the puff pastry

• 1 sheet of puff pastry (store-bought or homemade)
• 1 egg (for egg wash)

For the filling

• 2 salmon fillets (about 200g each), skin removed
• 2 medium leeks, white parts only, finely chopped
• 200g mushrooms, sliced
• 1 tablespoon olive oil
• 1 tablespoon butter
• 100ml heavy cream
• 1 garlic clove, minced
• Salt and pepper, to taste
• Fresh thyme (optional)

Optional substitutions

• Salmon alternatives: For a vegetarian version, replace the salmon with roasted vegetables such as zucchini or bell peppers.
• Dairy-free option: Swap heavy cream for a plant-based cream like coconut or almond cream.

Instructions

Step 1 — Prepare the filling

In a large skillet, heat the olive oil and butter over medium heat. Add the chopped leeks and sauté for about 5 minutes until they soften and become translucent. Stir in the sliced mushrooms and minced garlic, and cook for another 4–6 minutes until the mushrooms release their moisture and begin to brown.

Step 2 — Cook the salmon

Season the salmon fillets with salt and pepper. In a separate pan over medium-high heat, sear the salmon for 3–4 minutes per side until lightly cooked but still slightly underdone in the center — it will finish cooking inside the pastry. Remove from heat and set aside.

Step 3 — Combine the filling

Pour the heavy cream into the leek and mushroom mixture, stirring gently. Allow the cream to simmer briefly until it thickens slightly and coats the vegetables. Season with salt, pepper, and fresh thyme if using. Remove the pan from the heat and let the filling cool for a few minutes so it won’t make the pastry soggy.

Step 4 — Assemble the pastries

Preheat the oven to 200°C (390°F). On a lightly floured surface, roll the puff pastry sheet and cut it into two equal rectangles large enough to enclose each salmon fillet with filling. Spoon a portion of the leek-and-mushroom mixture into the center of each rectangle, place a salmon fillet on top, then add a little more of the vegetable mixture over the salmon to distribute flavor evenly.

Step 5 — Seal and bake

Fold the pastry over the filling and seal the edges by pressing with a fork. Brush the tops with beaten egg for a glossy, golden finish. Transfer the pastries onto a baking sheet lined with parchment paper and bake for 20–25 minutes, or until the pastry is puffed and deeply golden. Let the pastries rest a few minutes before serving.

Notes & Tips

• Keep the pastry cold: Work quickly and keep the puff pastry chilled until just before baking to achieve maximum flakiness.
• Avoid overfilling: Too much filling can cause leakage. Use a moderate amount so the pastry seals cleanly.
• Flavor boosters: Fresh herbs like thyme or dill add brightness; a squeeze of lemon over the finished pastry brightens the dish.
• Sealing tips: Brush a thin line of water along the pastry edges before pressing to help them stick together.

Serving Suggestions

Serve the salmon puff pastry with a fresh green salad, steamed seasonal vegetables, or roasted new potatoes. A light vinaigrette on the side helps cut the richness of the pastry. For a wine pairing, a crisp white such as Sauvignon Blanc or a lightly oaked Chardonnay complements the flavors nicely.

Salmon is an excellent source of omega-3 fatty acids, which support heart health. Leeks and mushrooms add fiber, vitamins, and minerals for a balanced plate.

Storage and Reheating

Refrigerate leftovers in an airtight container for up to 2 days. To reheat and preserve crispness, warm the pastry in a preheated oven at 180°C (350°F) until heated through and crisp on the outside. Avoid microwaving, which makes the pastry soggy.

Frequently Asked Questions

• Can I use frozen puff pastry? Yes — thaw it fully according to package instructions before using.
• Can this be prepared ahead? Prepare the filling in advance and assemble just before baking to keep the pastry crisp.
• What other fish can I use? Cod or trout work well; for a vegetarian version, use roasted vegetables instead of fish.
