Making a Salmon Wellington at home couldn’t be easier… or more delicious. Imagine a moist and perfectly seasoned piece of salmon tucked away under a creamy spinach filling. Then, it’s wrapped up in a buttery, flaky crust! If you ever want to impress your friends and family, or just have a restaurant-style meal at home – you MUST make this.

Okay y’all… I even impressed MYSELF with this recipe. Salmon Wellington. You guys know I barely eat red meat, so even though I recently tried the beef version – the salmon variety is supreme to me! The cheesy sautéed spinach topping takes it to the next level. Let’s get into it.
Ingredients
- Frozen Puff Pastry Dough – The main key to making puff-pastry salmon is… puff pastry of course. Like my other puff pastry recipes, I use the frozen kind and let it thaw on the counter for 20 or so minutes before cooking.
- A Fantastic Cut of Salmon – We’re going with a simple spice blend for seasoning the fish, so grab some quality pieces of salmon! Be sure it’s skinless and boneless.
- Sautéed Spinach – Along with the fish, my salmon wellington recipe has a beautiful, cheesy sautéed spinach mixture. You’re going to need spinach, cream cheese, fresh parmesan, and a hint of lemon juice to lighten it up.
- Egg Wash – The key to a beautiful crust is in egg wash! All you need is an egg + some water. Whisk it up until smooth, and then brush it onto the pastry right before baking.
How to Fold a Salmon Wellington
I added some process photos below so you can get a sense of exactly how to fold this.
The fun part is, you can actually make Salmon Wellington – also known as Salmon en Croute – two ways: with the spinach dip on top of the salmon, or on the bottom!
My photos below show how to assemble and fold the wellington so the spinach is on the top (personal preference as far as looks) but in the instructions card, I left instructions for both options. It tastes amazing no matter where you place the spinach.
In essence, making salmon wellington is so much easier than it looks! We’re going to start by making the spinach mixture on the stove while the puff pastry thaws on the counter. Once everything is smooth, take that off of the heat and prepare your salmon with spices & a secret ingredient – Dijon mustard!
Finally, assemble your pastries, fold, and seal with a bit of egg wash (it acts as a glue). Score the top of the pastry using a knife to help some of the steam escape while cooking. Then bake for about 20 minutes and voila! I love to sprinkle a bit of flaky salt and fresh parsley on top for flavor and color.



FAQs
You certainly can! I love the frozen kind just for convenience, but if you have an amazing puff pastry dough recipe – feel free to use that.
Nope – add your raw (but seasoned) salmon to the puff pastry because it’ll all cook together in the oven. You don’t want your salmon to be dry and overcooked! Be sure to remove any skin from the salmon fillets.
Dijon mustard is my secret ingredient; it helps keep the salmon moist and seals in those beautiful flavors. Don’t skip this ingredient.
