What Is Salmon en Croute?
In the culinary world, the term “en croute” defines a food that is wrapped in pastry dough and then baked in the oven. The dough can be puff pastry or ordinary pie dough.
Salmon en croute has another name — salmon wellington. And as the name implies, it has a great popular cousin, beef wellington.
Back in the 14th-16th century, beef wellington was the fashionable dish among the higher classes. A fillet of beef is coated with paté and mushroom before being wrapped in ham and pastry and then baked.
Chefs have since experimented with this recipe using various types of proteins, especially those that might be easier to find and more affordable. Over time, salmon emerged as the ideal ingredient for this scrumptious and impressive recipe.
Is Salmon en Croute Healthy?
Baked dishes, in general, are often considered unhealthy due to their high saturated fat and sodium content.

Main Ingredients in Salmon en Croute
Before we go in, let’s take a look at the required ingredients for this salmon en croute recipe:
Salmon fillets: Once seasoned, salmon is wrapped in the puff pastry to soak up the goodness of the other filling ingredients. The fish then comes out moist, buttery, and irresistibly satisfying.
Puff pastry: The pastry dough becomes buttery and crunchy once baked. It also acts as a cover to envelop the salmon fillet and keep the filling succulent.
Mushrooms: This hearty element is sauteed in olive oil and garlic until softened. This combination provides subtle moisture that seeps into the salmon and keeps it tender throughout the baking process.
Spinach: Spinach adds a scrumptious flavor and a moist layer to the filling. Plus, this veggie is packed with folate, vitamin C, K, and A.
Lemon zest: We use it to add a dose of freshness and bright acidity to the salmon.
Egg yolk: Brushing the egg wash over the top of the pastry is a simple technique to help it turn out golden brown in the oven.
Don’t be intimidated by salmon en croute’s long list of ingredients, the dish is quite straightforward and easy to make. Read below to see the recipe and get some handy tips.

Salmon can pair nicely with a wide range of herbs and spices due to its bold and rich flavor. Some of the best complements are dill, fennel, tarragon, parsley, basil, and thyme. You can go wild and try out new combinations to find out your favorite.
A common mistake when baking pastry dishes is allowing your crust to go soggy. To prevent this unpleasant situation, make sure your filling is dry without any excess moisture.
You can also make a hole in the pastry to allow the steam to escape in the oven. This way the liquid will not leak, resulting in a nice crunchy base.
Can I Cook Salmon from Frozen?
For this particular recipe, we don’t recommend using frozen salmon. The frozen fish will release excess water during the baking process, resulting in a runny filling and soggy crust.
