    1. Heat 1 tablespoon oil in a large pan over medium heat. Add onion; cook and stir until softened, about 5 minutes. Add mushrooms and 1 teaspoon garlic; cook and stir until mushrooms are soft, about 5 minutes. Season with salt and black pepper. Transfer onion and mushroom mixture to a small bowl.
    2. Heat remaining 1 tablespoon oil in the same pan. Add remaining 1 teaspoon garlic; cook and stir until fragrant, about 30 seconds. Add spinach; cook and stir until wilted, 3 to 5 minutes. Season with salt and black pepper. Transfer to another bowl.
    3. Preheat oven to 180 degrees C. Line a glass baking dish with baking paper.
    4. Dust work surface with flour. Lay 1 puff pastry sheet out on work surface. Spread onion and mushroom mixture evenly across pastry, leaving a 1cm border. Centre the salmon fillet on top. Sprinkle paprika over salmon and top with wilted spinach. Cover with second puff pastry sheet. Fold over and crimp edges to seal. Brush top with beaten egg. Transfer to baking dish.
    5. Bake in the preheated oven until pastry is golden, 40 to 45 minutes. Remove and let stand for 5 minutes. Slice into 4 portions.
    6. To serve: Whisk mayonnaise, lemon juice, Dijon mustard and dill together in a small bowl. Spoon sauce onto 4 plates and place a piece of salmon en croute on each.


    You can substitute spinach with asparagus spears.

    For me, this needs a major alteration that I tried! Made it once according to directions and flavors were great but it was an OVERWHELMING mouthful of pastry that I had to cook longer in order to cook the pastry through. The next time I made it I used just one pastry sheet and rolled it thin with a rolling pin. Same everything cooked to the lower range of time, just with one sheet of pastry rolled thin. It turned out to be "restaurant quality". With one pastry sheet, this will be added to the rotation.  -  18 Jan 2019  (Review from Allrecipes USA and Canada)


    Made just as directed and it was delicious. The sauce is great and made enough to use with veggies for a dip.  -  14 Aug 2016  (Review from Allrecipes USA and Canada)


    Ooo la la! A little bit of work but a lot of great taste! If you want people to be impressed, serve this. It's not difficult even though there are many steps.  -  08 Jun 2016  (Review from Allrecipes USA and Canada)
