Baked Salmon in Puff Pastry with Cremini Mushroom Duxelle


This delicious recipe for salmon wellington, or salmon en croûte, features a cremini mushroom sauce atop wild king salmon, wrapped and baked in puff pastry. This elegant meal is much easier to prepare than you might think-- puff pastry is easy to work with. I served with with a beurre blanc sauce, as well. We loved this!

Step 1


Rinse and thoroughly pat dry cremini mushrooms before using a food processor or sharp knife to finely mince.

Melt butter in a sauté pan over medium heat. Add shallots and sauté until soft. Stir in cremini mushrooms and simmer for 7 to 10 minutes, stirring occasionally, allowing the mushrooms to cook down while their moisture evaporates.

Add white wine, thyme and salt. Simmer for an additional 5 to 7 minutes.

Remove from heat and stir in whipping cream. Use immediately or cover and refrigerate. Makes 1 cup.


I froze the remaining Duxelles, for a month. It thawed perfectly, and was delicious spread over puff pastry and rolled, sliced into pinwheels. Bake at 400°F for about 10 to 12 minutes.

Elegant yet easy to prepare, salmon wellington makes a lovely entrée for a dinner party or evening in as the puff pastry parcels can be prepared and refrigerated for up to two hours before being baked.


Cut puff pastry into four equal 5-inch x 8-inch (13-centimeters x 20-centimeters) sheets. Approximate measurements are suitable.

Spread 1/4 cup mushroom duxelle evenly onto each sheet of puff pastry, leaving a 1/2-inch (1 centimeter) margin at the edges. Place a salmon fillet in the center of each prepared pastry, seasoning each with a sprinkle of salt.

Fold up edges in a lengthwise and press puff pastry together to seal a seam across the center of the salmon fillet. Flip pastry over so that seam is hidden and gently press the sides together to close.


I brushed an egg wash over each wellington, to give a lovely golden color to the pastry.

Bake salmon wellington at 400°F (205°C) for 15 minutes. Lower heat to 325°F (165°C) and bake for an additional 15 to 20 minutes until puff-pastry is flaky and golden brown.

If using previously frozen salmon, allow fillets to completely thaw before assembling the salmon puff-pastry.


These can also be frozen, and then baked for a little extra time. I also tested reheating one of these, after they were baked, in a conventional oven (do not microwave), and they turned out just fine!
