Salmon Wellington is a delightful twist on the classic Beef Wellington, featuring succulent salmon wrapped in flaky puff pastry. This dish combines the rich flavors of dijon mustard and garlic-infused spinach, creating a gourmet meal that's perfect for special occasions or a luxurious weeknight dinner.
While most of the ingredients for this recipe are common, you might need to visit the supermarket for a few items. Puff pastry is typically found in the frozen section, and make sure to get a high-quality, skinless salmon fillet. Fresh spinach is essential for the best flavor, and dijon mustard adds a unique tanginess that regular mustard can't match.

Ingredients For Salmon Wellington Recipe
Salmon fillet: A rich, flavorful fish that serves as the centerpiece of this dish.
Puff pastry: A light, flaky dough that encases the salmon, creating a beautiful golden crust.
Dijon mustard: Adds a tangy, slightly spicy flavor that complements the salmon.
Egg: Used for brushing the pastry to give it a golden, shiny finish.
Olive oil: Used to sauté the spinach and garlic, adding a rich flavor.
Spinach: Provides a fresh, slightly earthy taste that pairs well with the salmon.
Garlic: Adds a robust, aromatic flavor to the spinach.
Technique Tip for This Recipe
When working with puff pastry, ensure it remains cold until you're ready to use it. This helps maintain its structure and results in a flakier, more delicate crust. If the pastry becomes too warm, it can become difficult to handle and may not puff up as desired. If necessary, chill the assembled Salmon Wellington in the refrigerator for 10-15 minutes before baking to ensure the pastry is at the optimal temperature.

How to Store or Freeze This Dish
Allow the salmon wellington to cool completely before storing. This helps prevent condensation, which can make the puff pastry soggy.
Wrap the salmon wellington tightly in plastic wrap or aluminum foil. Ensure there are no gaps to keep out air and moisture.
Place the wrapped salmon wellington in an airtight container. This provides an extra layer of protection against freezer burn and keeps the flavors intact.
Label the container with the date of preparation. This helps you keep track of how long it has been stored.
Store the salmon wellington in the refrigerator if you plan to eat it within 2-3 days. For longer storage, place it in the freezer where it can last up to 2 months.
To reheat, preheat your oven to 350°F (175°C). If frozen, allow the salmon wellington to thaw in the refrigerator overnight.
Place the salmon wellington on a baking sheet lined with parchment paper. Cover it loosely with aluminum foil to prevent the puff pastry from over-browning.
Bake for 15-20 minutes or until heated through. Remove the foil for the last 5 minutes to crisp up the puff pastry.
Let it rest for a few minutes before slicing and serving. This helps the salmon wellington retain its shape and makes for a better presentation.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Salmon Wellington on a baking sheet lined with parchment paper. Cover it loosely with aluminum foil to prevent the puff pastry from becoming too brown. Heat for about 15-20 minutes or until warmed through.
For a quicker option, use a toaster oven. Set it to 350°F (175°C) and place the Salmon Wellington on the rack. Heat for about 10-15 minutes, checking occasionally to ensure the pastry doesn't overcook.
If you're in a hurry, the microwave can be used, but it might make the puff pastry less crispy. Place a slice of the Salmon Wellington on a microwave-safe plate. Cover it with a damp paper towel to retain moisture. Heat on medium power for 1-2 minutes, checking to see if it's warmed through.
For an air fryer, preheat it to 350°F (175°C). Place the Salmon Wellington in the basket and heat for about 5-7 minutes. This method helps to keep the pastry crispy while reheating the salmon evenly.
If you prefer a stovetop method, use a skillet over medium-low heat. Add a small amount of olive oil to the pan. Place the Salmon Wellington in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through to ensure even warming.
