Swordfish Wellington Recipe – Luxurious Prosciutto-Wrapped Puff Pastry Seafood Dish

Swordfish Wellington Recipe

This Swordfish Wellington recipe elevates fresh swordfish with creamy leeks, savoury prosciutto, and flaky puff pastry for a rich and elegant seafood entrée. Featured on Fish the Dish, this luxurious dish transforms simple ingredients into a restaurant-quality centerpiece that’s perfect for special occasions and dinner parties.

The Inspiration

Inspired by the classic Beef Wellington, this seafood adaptation brings a coastal twist to a traditionally rich and indulgent dish. On Fish the Dish, hosts Spencer Watts are known for reimagining iconic recipes in approachable yet elevated ways, and this Swordfish Wellington recipe is a perfect example of that creative philosophy.

Swordfish, with its firm and meaty texture, holds up beautifully when wrapped and baked, making it an ideal substitute for traditional beef. The creamy leek mixture adds depth and richness, while prosciutto provides a salty, savoury layer that enhances the natural flavour of the fish. Encased in buttery puff pastry, the result is a golden, crisp exterior that contrasts perfectly with the tender seafood inside.

This dish draws inspiration from French and British culinary traditions, where pastry-wrapped mains are often served for festive occasions. It’s designed to impress visually and deliver complex flavour layers while still being achievable for confident home cooks.

Ingredients

• 3 tablespoons (45ml) butter
• 1 cup (240ml) 35% cream

• Pinch of salt and white pepper
• 4 swordfish fillets (4 ounces each or 120 grams each)
• 4 sheets frozen puff pastry
• 8 slices prosciutto
• 1 egg

Method

• Preheat oven to 400^oF (205^oC).

• Cook for another 5-6 minutes, or until cream is completely reduced.
• Remove from heat and allow to cool completely.
• Roll out one thawed sheet of puff pastry into a large rectangle.
• Place 2 slices of prosciutto on second half of puff pastry.
• Place one swordfish fillet over the prosciutto, and season with pepper.
• Add one quarter of the cold creamed leeks over the fish, and wrap with prosciutto.
• Fold puff pastry over the whole thing and seal edges using the tips of a fork.
• Whisk egg in a bowl, and brush over the puff pastry.
• Start over for the 3 remaining swordfish fillets.
• Place on baking sheet and cook in preheated oven for 12-15 minutes.

Serving Suggestions

This Swordfish Wellington recipe is ideal for elegant dinner parties, holiday feasts, or any occasion where you want to serve a show-stopping main course. Serve each Wellington individually plated with a light sauce or reduction on the side to complement the richness of the pastry and cream-filled leeks.

Pair it with roasted vegetables, buttery mashed potatoes, or sautéed greens like Cumin Flavoured Kale to balance the richness of the dish. For a more refined presentation, slice the Wellington in half to reveal the layers of swordfish, prosciutto, and creamy leeks inside the golden pastry shell.

Wine pairings such as Chardonnay, Pinot Gris, or light-bodied red wines enhance the buttery pastry and savoury seafood profile. This dish also works beautifully as the centerpiece of a multi-course dinner featuring lighter starters like shrimp rolls or ceviche.
