What Is Salmon Wellington?
You might know salmon wellington as salmon en croute. En croute is a French term used to reference any food wrapped in a puff pastry dough and baked in the oven – which is exactly what salmon Wellington is!
Like other Wellington recipes, such as beef Wellington, salmon Wellington features a filet of salmon often topped with a filling wrapped in pastry dough and baked until golden brown.
Ingredients You’ll Need
- Salmon – Use large, thick filets, and make sure they’re fully thawed.
- Puff Pastry – Like the salmon, you want to make sure your puff pastry is thawed.
- Large Egg – Beat this in a bowl to use as an egg wash, preventing the pastry from becoming soggy and creating a beautiful golden exterior.
- Cream Cheese – Use brick-style cream cheese, not tub varieties! Full-fat is best.
- Frozen Spinach – We recommend using frozen spinach over fresh spinach as it’s already finely chopped. Make sure it’s thawed and drained well.
- Mozzarella Cheese – Feel free to experiment with any cheese you like best.
- Salt and Black Pepper – Adjust to taste.
Step-By-Step Instructions for Puff Pastry Salmon
- Prepare the filling. Combine the cream cheese, spinach, and mozzarella in a mixing bowl. Season to taste, and set aside.
- Fill. Roll the puff pastry out into a rectangle on a lightly floured surface. Spoon the cream cheese mixture into the center, leaving space around the edges. Place the salmon filet over the cream cheese, and add salt and pepper to taste.
- Fold. Carefully fold the edges of the puff pastry over the salmon, pressing the edges together to create a seal.
- Add the egg wash. Transfer the salmon puff pastry to a baking sheet lined with
parchment paper. Make sure the seem side is down! Then, use a sharp knife to make slits on the top. Brush the top of the salmon wellington with egg wash.
- Bake. Transfer the baking sheet to a preheated oven, and bake until the puff pastry is golden brown and the salmon reaches an internal temperature of 145 degrees Fahrenheit.
- Rest. Allow the cooked salmon en croute to cool for a few minutes before slicing and serving.
- Add Veggies. Feel free to incorporate more or different vegetables such as onions or mushrooms.
- Swap the Cheese. Parmesan or Boursin cheese would also taste great!
- Use Phyllo Sheets. Swap out the puff pastry, and wrap your salmon with phyllo sheets instead.
- Add Citrus. Include a dash of lemon juice and/or lemon zest for bright, refreshing notes that balance out some of the heaviness of the fats.
Salmon en croute can easily be served as a complete meal on its own. However, it also pairs wonderfully with a variety of side dishes.
