James Martin’s Salmon En Croute is a show-stopping centerpiece that looks incredibly difficult but is surprisingly achievable. James strips away the fuss of making puff pastry from scratch, championing high-quality store-bought pastry to make this a realistic weeknight luxury or Sunday feast. The secret to his version is moisture management: he uses a layer of cream cheese and herbs (or sometimes a watercress/spinach mousse) between the fish and the pastry to keep the salmon succulent while preventing the bottom of the pastry from getting soggy.

James Martin Salmon En Croute Ingredients
- 800g Salmon Fillet
- 500g Puff Pastry
- 150g Cream Cheese
- 1 bunch Fresh Dill
- 1 bunch Watercress or Spinach: (Optional) Wilted and squeezed very dry.
- 1 Lemon
- 1 Egg
- Salt & Black Pepper
- Plain Flour: For dusting.

How To Make James Martin Salmon En Croute
- Prep the Filling: In a small bowl, mix the cream cheese, chopped dill, lemon zest, salt, and plenty of black pepper. Tip: If using spinach/watercress, ensure it is squeezed bone-dry before mixing, or it will make the pastry soggy.
- Prep the Pastry: Preheat your oven to 200°C (400°F). On a lightly floured surface, roll out the puff pastry into a large rectangle (approx. 30cm x 40cm), about the thickness of a pound coin.
- Assemble: Place the salmon fillet in the center of the pastry. (If using two thinner fillets, sandwich the filling between them). Spread the herb cream cheese mixture generously over the top of the salmon.
- Wrap: Brush the edges of the pastry with a little beaten egg. Fold the longer sides of the pastry over the salmon to encase it, overlapping them slightly. Trim off any excess pastry at the ends and tuck them underneath to create a neat parcel.
- Score: Flip the parcel over so the seam is on the bottom and place it on a baking tray lined with parchment paper. Brush the entire surface with the beaten egg. Lightly score the top of the pastry with the back of a knife in a crisscross or diamond pattern (be careful not to cut all the way through to the fish).
- Bake: Bake in the preheated oven for 20–25 minutes until the pastry is puffed and deep golden brown.
- Rest: Remove from the oven and let it rest for 5–10 minutes before slicing. This allows the salmon to finish cooking in the residual heat and makes it easier to carve.

Recipe Tips
- Cool the Filling: If you cook spinach for the filling, let it cool completely before putting it on the pastry. Hot filling melts the butter in the raw pastry and ruins the puff.
- No Soggy Bottoms: James sometimes suggests placing the baking tray in the oven while it preheats. Placing the pastry onto a hot tray helps crisp up the base immediately.
- Pin Bones: Run your finger down the center of the raw salmon fillet to check for bones. Remove them with tweezers; finding a bone ruins the elegance of the dish.
- Temperature: If you have a meat thermometer, the internal temperature of the salmon should be around 50°C (122°F) for medium-rare/medium.

What To Serve With Salmon En Croute?
Since James Martin’s Salmon En Croute is a rich, buttery dish, it is best balanced with simple, fresh sides. Buttered new potatoes or crushed baby potatoes with mint are the ideal accompaniment, while vibrant greens like steamed asparagus, tenderstem broccoli, or wilted green beans add necessary color and crunch. For a final elegant touch, serve it with a jug of zesty lemon hollandaise or a light parsley cream sauce to tie the meal together.
How To Store Leftovers Salmon En Croute?
- Fridge: Store in an airtight container for 2 days.
- Freezer: Not recommended. While safe to freeze, the pastry will lose its texture and become soggy upon thawing.
How To Reheat Salmon En Croute?
Microwave: Avoid. It will turn the pastry soft and chewy.
- Oven: Place on a baking tray and cover loosely with foil (to prevent burning the pastry). Heat at 180°C (350°F) for 15–20 minutes. Remove the foil for the last 5 minutes to re-crisp the pastry.
FAQs
Yes, you can build the parcel up to 6 hours ahead and keep it in the fridge. Brush with egg wash just before baking.
Usually moisture. Ensure the salmon is patted dry, and if using spinach, squeeze every drop of liquid out. Also, try baking on a preheated tray.
Yes, for a lighter, crunchier version. Layer 4-5 sheets with melted butter in between, but reduce cooking time slightly as phyllo browns faster.
