2. Ingredient List 🧾
Here’s everything you’ll need to make a delicious Salmon Wellington that’s sure to impress. I’ve grouped the ingredients roughly by the steps you’ll follow, so it’s easy to find what you need when you’re cooking. Measurements are in both metric and imperial, just to keep things straightforward.
Ingredients for Salmon Wellington
- 1 sheet puff pastry (about 320g / 11 oz), thawed if frozen
Tip: Use a good-quality puff pastry — it’s a game-changer for that perfect flaky, golden crust.
- 2 salmon fillets (about 180g / 6 oz each)
Choose fresh, skinless salmon if possible. It cooks evenly and stays juicy inside.
- 2 tablespoons Dijon mustard
Adds a gentle tang that takes this dish to the next level.
- 1 cup fresh spinach (about 30g / 1 oz)
Baby spinach works beautifully here — it wilts quickly and gives a lovely, tender texture.
- 1 small onion (about 70g / 2.5 oz), chopped
Yellow onions are a safe bet for sweetness and depth.
- 2 cloves garlic, minced
Fresh garlic brings that punchy flavour you don’t want to skip.
- 1/2 cup cream cheese (120g / 4 oz), full fat preferred
Full-fat cream cheese makes the filling luxuriously smooth. If you’re after a dairy-free option, try vegan cream cheese or mashed silken tofu.
- 1 egg, beaten
This helps the pastry get that beautiful golden sheen.
- Salt and pepper to taste
Ingredient Notes & Substitutions
- Puff pastry: If you have a gluten sensitivity, some brands offer gluten-free puff pastry, but check the label carefully. Alternatively, filo pastry is lighter but more delicate to handle.
- Mustard: If you find Dijon too sharp, wholegrain mustard is a nice mellow alternative that adds texture, or try a mild English mustard for a gentler heat.
- Cream cheese substitutes: For those avoiding dairy, vegan cream cheeses based on coconut or cashews work pretty well. Just make sure they’re soft and creamy.
Getting these ingredients just right really sets you up for success — fresh, quality components elevate the dish from everyday to special. Now, with everything at hand, the cooking part is going to feel smooth and enjoyable. Trust me on this one!
Step-by-Step Instructions with Pro Tips for Salmon Wellington 🍳
Making Salmon Wellington might sound fancy, but it’s truly a kitchen joy once you break it down. Let’s walk through each step, with some handy tips to make sure your Wellington turns out perfectly flaky and flavourful.
1. Preheat the oven to 400°F (200°C)
Get your oven warming up early on — this is important so it’s nice and hot when your Wellington’s ready to pop in. A hot oven means that golden crisp puff pastry we’re after.
2. Sauté the onion and garlic until translucent
Heat a little oil in a pan over medium heat. Toss in the chopped onion and minced garlic. You want the onion to become translucent, which means it looks clear and soft but not browned. This usually takes 3-5 minutes.
Pro Tip: Keep stirring and watch the onion closely— it’s a game-changer because it sweetens the base layer without overpowering the salmon.
3. Add spinach and cook until wilted; then cool the mixture
Throw the fresh spinach into the pan with the onion and garlic. It won’t take long—just a minute or two until the leaves are soft and reduced. Remove from heat and let this cool completely.
Chef’s Note: Letting it cool prevents the puff pastry from going soggy later on.
4. Mix the spinach mixture with cream cheese, salt, and pepper
In a bowl, combine your cooled spinach mix with cream cheese. A good pinch of salt and pepper enhances the flavour. This creamy layer adds moisture and richness, taking your Wellington to the next level.
5. Place puff pastry on a baking sheet; spread Dijon mustard in the centre
Lay out your sheet of puff pastry on a lined baking tray. Spread 2 tablespoons of Dijon mustard right in the middle — this tangy kick complements the salmon beautifully. Don’t spread it too close to the edges to avoid seepage.
6. Layer salmon fillets over the mustard
Arrange your two salmon fillets on top of the mustard. Make sure they’re evenly spaced. The mustard acts like a flavour bridge, so don’t skip this step.
7. Spread the spinach and cream cheese mixture over the salmon
Spoon the spinach and cream cheese mix evenly over the salmon. This adds a creamy, fresh layer — trust me on this one, it brightens everything up.
8. Fold pastry over filling and seal edges
Now, gently fold the puff pastry over the filling to wrap it all up. Press the edges firmly to seal them well.
Pro Tip: Use a little of the beaten egg as glue on the edges before sealing to make sure nothing leaks during baking.
9. Brush the pastry with beaten egg
Give the wrapped Wellington a good brush with the beaten egg. This step is key — it gives that golden, glossy finish everyone loves.
10. Bake for 20-25 minutes until golden brown
Pop the Wellington in the oven for about 20 to 25 minutes. You’re looking for that puff pastry to turn a deep golden brown and puff up nicely.
Keep an eye near the end — ovens can vary. Once the pastry is golden and flaky, it’s ready to come out. Let it rest for a few minutes before slicing so the filling sets a little.
Following these steps carefully will help you nail a stunning Salmon Wellington every time. Cooking this together is almost as rewarding as the delicious result!
Recipe Variations & Serving Suggestions 🍽️
Now, here’s the fun part—putting your own twist on Salmon Wellington to make it uniquely yours. If you fancy a bit of zest, try adding chopped sun-dried tomatoes into the spinach and cream cheese mix. They bring a burst of sweet, tangy flavour that’s a real game-changer. For those who love a spicy edge, sprinkle some red pepper flakes into the filling. It adds a gentle heat that takes this dish to the next level without overpowering the delicate salmon.
When it comes to serving, keep things simple yet indulgent. This Wellington pairs beautifully with creamy polenta—the smooth texture balances the flaky pastry perfectly. Fresh herbs like dill or parsley scattered over the top brighten up the plate and add a fresh note that complements the rich filling. Roasted baby potatoes or a crisp green salad work well too, giving you a variety of textures and tastes.
If you have leftovers, don’t worry—they keep well! Wrap any leftover pieces tightly in cling film or foil and store them in the fridge for up to two days. When reheating, pop the portions in the oven at 180°C (350°F) for about 10 minutes rather than using a microwave. This way, you’ll keep the pastry crisp and the salmon tender. Trust me on this one—it makes all the difference!
Why This Recipe Works ✔️
Here’s the secret behind why this Salmon Wellington turns out so reliably delicious. The puff pastry acts like a perfect little jacket for the salmon, locking in moisture as it bakes. That means the fish stays tender and juicy instead of drying out—a real game-changer for flaky fish dishes. Meanwhile, the Dijon mustard spread adds just the right tang, cutting through the richness and adding a subtle kick.
Now, the spinach and cream cheese filling isn’t just about flavour—it’s about texture too. The cream cheese makes the mixture luxuriously creamy, which balances the earthiness of the spinach and the mild onion and garlic. Plus, as it warms inside the pastry, it melds beautifully with the salmon, making every bite smooth and satisfying.
By folding the pastry carefully around the filling and brushing it with egg, you get that golden, crisp crust that’s hard to beat. Trust me, these little touches take your Salmon Wellington from good to next-level fabulous.
6. Frequently Asked Questions (FAQ) ❓
Can I make this ahead?
Absolutely! You can prep the whole Wellington, wrap it tightly in cling film, and keep it in the fridge for a few hours before baking. Just let it come to room temperature for about 20 minutes before popping it in the oven to ensure even cooking.
Can I freeze it?
Yes, you can freeze the Salmon Wellington uncooked. Wrap it well in freezer-safe foil or cling film. When ready to bake, thaw it overnight in the fridge, then brush with the egg wash before baking as usual.
What’s the best substitute for cream cheese or Dijon mustard?
If you don’t have cream cheese, soft goat’s cheese or ricotta work wonders — they add a lovely creaminess without overpowering the salmon. For Dijon mustard, try wholegrain mustard or even a mild English mustard; just be mindful of the heat level.
Why did my pastry turn soggy?
Soggy pastry often happens if your filling is too wet or the salmon releases a lot of moisture. Make sure to drain cooked spinach well and pat the salmon dry before assembling. Also, avoid over-filling — a little goes a long way in keeping that crisp, golden crust.
