What is Salmon Wellington
Salmon Wellington or Salmon en Croute is a savory salmon pie where salmon is properly seasoned, then placed over a bed of creamy spinach and wrapped in puff pastry. The puff pastry is brushed with egg wash, then baked in the oven until golden.
Spinach and salmon is a match made in heaven, and when it’s wrapped in buttery and flaky puff pastry, it gets even better!
The Ingredients
You will need the following ingredients:
Complete list of ingredients and amounts can be found in the recipe card below.
- Puff pastry – I used ready store-bought puff pastry but you can, of course, make your own. If it’s frozen, make sure you thaw it in the fridge overnight.
- Salmon fillets – if frozen then thaw them completely before cooking.
- Butter, cream cheese, parmesan cheese, and an egg for the egg wash.
- Onion, garlic, and baby spinach leaves.
- Dried breadcrumbs, salt, and pepper.
I know that this salmon wellington looks so fancy, and probably complicated. But trust me, it’s actually SO easy to make. Let me show you how!
How to Make Salmon Wellington
- First, make the spinach mixture. In a pan melt the butter, and saute the diced onion until it’s soft and translucent.
- Add the spinach, and cook it until it just wilts (do not overcook it as it will still cook further in the oven). Season with black pepper, and lower the heat to low heat, then add the cream cheese. After the cream cheese melts, add the parmesan cheese and the breadcrumbs. Mix everything together and remove from heat and set aside.
- Season the salmon fillets with salmon and pepper. Then roll out the pastry sheet on your counter, cut it into halves (or in a size that’s good enough to fit the salmon and the filling).
- Place each salmon fillet in the center of the puff pastry sheet and leave about 2 inches around the edges. If the puff pastry sheet is not big enough, you can roll it out to make it a little bigger.
- Top each salmon fillet with the spinach mixture using a spoon, spread it evenly. Brush the edges of the puff pastry sheets with a beaten egg, and fold it as shown in the image below.
- Place the salmon on a greased or lined with parchment paper baking sheet seam side down. And make crosshatch slits on the top of each Wellington using a sharp knife.
- Bake at 200°C (390°F) for 30 minutes or until the pastry is golden.
How to Make Ahead, and Store.
- Make ahead: You can make these salmon wellingtons ahead of time, and place them in the freezer for up to 3 months. Take out of the freezer and bake for 40 minutes at 200°C (390°F).
- Store: Store in the fridge in an airtight container for up to 3 days.
- To reheat: Reheat in the oven at 180°C (356°F) for 10-15 minutes, or until warmed through. Or reheat in the microwave, however, puff pastry has a better texture if reheated in the oven.
What to Serve Salmon Wellington With?
- Serve with steamed veg on the side; broccolini (tenderstem), broccoli, or green beans.
- A side of potatoes is also great with salmon wellington, try scalloped potatoes, smothered potatoes, or mashed potatoes.
- Or go with a side salad that is simple enough for this dish, I like this simple tossed green salad, this delicious kale salad, or a roasted cauliflower salad.
Recommended Tools for This Recipe
- Saute pan. Make sure that you’re using the right size of pot or pan,
- Sheet pan. I used a quarter sheet pan as I only made 2 wellingtons.
- Garlic press. A kitchen essential.
- Sharp knife. This is the knife that I use all the time, a sharp knife is so important and if you want to invest in a new knife then a high-quality chef knife is what I recommend. This one is also currently on sale and well worth the money.
- Pastry brush. For the egg wash.

This was such an easy recipe to prepare. Followed directions to the tee-came out fabulous. Will make it at thanksgiving for my husband who dislikes turkey. One thing—very rich. A little goes a long way. Also, leftovers heat up beautifully and taste the same as first time.
