Similar to salmon en croute, a whole fillet is baked in puff pastry with mushrooms and spinach and served with a lemon-mustard mayo. It's a great dish to make if you're expecting company!
You can substitute spinach with asparagus spears.
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 US | 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 US | Canada)
Very tasty, and elegant enough to serve at a dinner party. It really needs the sauce for flavor. The sauce is fabulous. The sauce also happens to be fantastic on eggs, steak, chicken...you name it! And it keeps well in the fridge. - 24 May 2016 (Review from Allrecipes US | Canada)
