Trout Wellington

Anything your usual proteins can do, Canadian Seafood can do, too! A classic Wellington gets the rainbow trout treatment in a deluxe main course that looks as sensational as it tastes. We’ll walk you through the surprisingly simple preparation of the minced mushrooms and the zesty spinach mix, plus how to wrap it all in pastry. It’s truly a treasure chest of taste!


  • 2 rainbow trout fillets (300 g / 0.7 lb each; 600 g / 1.4 lb total)
  • 1 sheet (225 g) puff pastry
  • 1 egg (65 g)
  • For the mushroom duxelles (mince):
  • 1 tbsp (14 g) butter
  • ¾ cups (100 g) cremini mushrooms, finely chopped
  • ¼ tsp (0.8 g) fresh thyme, chopped
  • A pinch of salt and pepper
  • 1 tbsp (15 ml) white wine
  • For the spinach mixture:
  • 1 tbsp (14 g) butter
  • 1 shallot, chopped
  • 1 clove garlic, chopped
  • 2 cups (100 g) packed spinach, roughly chopped
  • 1 tsp (5 ml) lemon juice
  • ½ tsp (2.5 g) grainy Dijon mustard


To Prep

  1. Preheat oven to 350°F (177°C).

  2. Remove skin from trout and pat dry.

For the Duxelles

  1. Melt 1 tbsp butter in a large frying pan over medium heat. Add in mushrooms and thyme and season with salt and pepper. Cook for 8—10 minutes, stirring occasionally, until the liquid starts to evaporate and the mushrooms begin to turn golden.

  2. Add white wine to pan and reduce temperature to medium-low. Allow the wine to evaporate and moisture to cook out; about 3–4 minutes.

  3. Remove from heat and set aside to cool.

For the Spinach Mixture

  1. In a frying pan over medium heat, melt 1 tbsp butter. Add shallot and garlic and sauté 1 minute.

  2. Add the spinach, lemon juice, and Dijon, cooking until spinach has wilted.

  3. Remove from heat and set aside.

To Assemble

  1. Unroll 1 sheet of puff pastry. Spread mushroom duxelles over pastry in an even layer on one half of the pastry.
  2. Place 1 trout fillet on top of the duxelles. Layer the spinach mixture on top, followed by the second fillet.
  3. Tightly, but gently, wrap puff pastry around fish filling, pressing down all the way around to create a ½-inch pastry border. You can use a fork to seal the edges or your fingers to create a decorative border.
  4. Using the tip of a paring knife, gently score a crosshatch pattern into the pastry, being careful not to pierce through.
  5. Whisk 1 egg with 1 tbsp water and brush mix over pastry. Place in the fridge for 10 minutes before placing into oven.
  6. Bake for 30–35 minutes, or until the pastry is golden brown.
  7. Remove from oven and let rest on a cooling rack for 5 minutes. Slice and serve.

Health Benefits of Trout

  • Bone Health & Growth: Trout is an excellent source of vitamin D and a good source of phosphorus, which play a crucial role in building and maintaining strong bones and teeth and supporting normal growth.

  • Heart & Brain Health: As a source of omega-3 fatty acids, eating trout may promote the physical development of the brain, eyes, and nerves, and due to its low sodium and saturated fat content, it aids in reducing the risk of high blood pressure.

  • Lean & Heart-Friendly: Trout is a lean protein source, and its low sodium and saturated fat content helps lower risks associated with high blood pressure and heart diseases.
