🐟 What is Saumon en Croûte?

The term en croûte in French simply means “in a crust.” In this dish, fresh salmon fillets are carefully coated with a creamy filling, layered with vegetables or herbs, then wrapped in puff pastry and baked until golden brown.

The result? Flaky pastry on the outside, moist salmon inside, and a flavorful layer in between. Every bite is a delightful contrast of texture and taste.

🛒 Ingredients You’ll Need

This recipe serves 4 people:

2 large salmon fillets (about 150–200 g each, skin removed)

1 sheet puff pastry (store-bought or homemade, thawed if frozen)

2 tbsp butter

2 cloves garlic, minced

1 shallot, finely chopped

150 g fresh spinach leaves

200 g mushrooms, finely chopped (optional but traditional)

3 tbsp cream cheese or crème fraîche

1 tsp Dijon mustard

1 tbsp fresh dill (chopped)

1 egg yolk + 1 tbsp water (for egg wash)

Salt & pepper to taste

Lemon wedges, for serving

🍳 Step-by-Step Recipe

Step 1: Prepare the Filling

Heat butter in a skillet over medium heat.

Add garlic and shallots, sauté until fragrant.

Stir in chopped mushrooms and cook until they release moisture and become golden.

Add spinach and cook until wilted.

Stir in cream cheese (or crème fraîche), Dijon mustard, and fresh dill. Season with salt and pepper.

Remove from heat and let the filling cool completely.

Step 2: Prepare the Salmon

Pat the salmon fillets dry.

Season with salt, pepper, and a light squeeze of lemon.

If using two fillets, try to match them in size for even baking.

Step 3: Assemble the En Croûte

Roll out puff pastry slightly to fit your salmon.

Place one salmon fillet in the center of the pastry.

Spread the cooled spinach-mushroom filling evenly over the fillet.

Place the second fillet on top, like a sandwich.

Fold the puff pastry over the salmon, sealing the edges well. Trim excess pastry if needed.

Brush with egg wash for a golden finish.

Optional: Use pastry scraps to decorate with leaves or patterns.

Step 4: Bake the Salmon

Preheat oven to 200°C (400°F).

Place the wrapped salmon seam-side down on a parchment-lined baking tray.

Bake for 25–30 minutes, or until the pastry is golden brown and crisp.

Let it rest for 5 minutes before slicing.

🌟 Serving Suggestions

Slice into thick portions and serve with a drizzle of hollandaise sauce or a light lemon butter sauce.

Pair with roasted asparagus, baby potatoes, or a crisp green salad.

A glass of Chardonnay or Champagne complements the richness beautifully.

✨ Tips for Success

Cool the filling completely before spreading it over the salmon, or the pastry may become soggy.

Seal edges well to prevent leaks while baking.

Use center-cut salmon fillets for even thickness.

Don’t overbake – salmon should stay moist inside while the pastry turns crisp outside.
