A whole fillet is baked in puff pastry with mushrooms and spinach and served with a lemon-mustard mayo.
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)
