How to Make Salmon en Croute
-
Preheat your oven to 200°C/400°F, setting the stage for a delightful meal ahead. This temperature will ensure your pastry becomes beautifully golden and flaky.
-
Chop the kale finely, removing any thick ribs, and combine with softened mascarpone or cream cheese in a bowl. Add lemon juice, salt, and pepper, stirring until it forms a lovely, thick paste.
-
Roll out the puff pastry on a lightly floured surface, aiming for a rectangle about 1/8″ thick. This will give you a sturdy wrap for your flavorful filling.
-
Place the seasoned salmon pieces flat in the center of the pastry rectangle. Spread the kale mixture generously on top of the salmon, ensuring every bite will burst with flavor.
-
Brush the edges of the pastry with the beaten egg to create a perfect seal. Fold the sides over the filling and pinch them together securely, crafting an envelope for the salmon and kale.
-
Flip the filled pastry gently and set it on a parchment paper-lined baking sheet. Brush the entire surface with the egg wash, giving it that irresistible golden hue when baked.
-
Optional: If you have leftover pastry, create decorative shapes and place them atop the croute. Brush them with egg wash for a beautiful finish.
-
Vent the pastry by making 3-4 small slits on top. Bake in the preheated oven for about 30 minutes, until the pastry puffs up and turns a lovely golden brown.
-
Rest for 5 minutes before serving, allowing the flavors to meld together beautifully.
Optional: Garnish with fresh herbs for an extra pop of color.

Expert Tips for Salmon en Croute
• Perfect Pastry: Ensure your puff pastry is fully thawed but chilled before rolling to maintain that flaky texture.

Salmon en Croute Recipe FAQs
What type of kale should I use for the filling?
Absolutely! I recommend using black kale, also known as cavolo nero, for its robust flavor and texture that perfectly complements the salmon. If you can’t find it, regular curly kale works, but be sure to finely chop it to avoid chewy bits.
How should I store leftover Salmon en Croute?
Once prepared, store any leftover Salmon en Croute in an airtight container in the fridge for up to 3 days. To reheat, pop it back in the oven at 180°C/350°F for about 10-15 minutes to restore its crispy texture.
Can I freeze Salmon en Croute?
Yes! You can freeze unbaked Salmon en Croute for up to 2 months. Wrap the pastry tightly in plastic wrap and foil to avoid freezer burn. To bake, remove from the freezer and let it thaw overnight in the fridge. Bake at 200°C/400°F for about 25 minutes until golden brown.
What should I do if my puff pastry is not rising properly?
If your puff pastry isn’t puffing up as it should, check the following: ensure your oven is preheated to the correct temperature, and that your pastry is chilled before baking. Also, remember to cut slits for ventilation; this allows steam to escape, helping that lovely puffed effect!
Is this recipe suitable for people with allergies?
If there are allergies present, make sure to substitute the mascarpone or cream cheese for a dairy-free alternative, and ensure that the puff pastry you use is free of allergens. Always double-check ingredient labels to be certain!
How do I know when the Salmon en Croute is fully cooked?
Look for a beautifully golden-brown color on the puff pastry, and make sure the internal temperature of the salmon reaches 145°F (63°C). If you’re unsure, you can use a food thermometer for the best results.
