I first made it years ago, after finding it in the one cookbook Colin owned when we were dating. I think it was also the only book he actually owned, and the only reason he owned it was that he's received a Chapters gift card as an apology from his ISP, for all the service problems he'd had. And that's what I think of everytime I make it! Anyways, it's a Jaime Oliver recipe- Roasted Fillet of Beef Rolled in Herbs & Porcini, & Wrapped In Prosciutto- from The Naked Chef Takes Off. It's delicious. It's fool-proof.
Roasted Fillet of Beef Rolled in Herbs & Porcini, & Wrapped In Prosciutto
As far as roasted meat goes, this is extremely fast and simple, yet decadently rich. One of the tricks, whether you buy it in a deli or a supermarket, is to ask them to slice your prosciutto and lay it side by side on a piece of waxed paper. Serves 4.
12-18 slices prosciutto or Parma ham
3 cloves of garlic, peeled
1 good handful of dried porcini, soaked in around 285ml boiling water
3 good sized pats of butter
Juice of 1/2 a lemon
Sea salt and freshly ground black pepper
900g/2lb fillet of beef (preferably from the middle, left whole)
1 good handful of fresh rosemary and thyme, leaves picked and chopped
2 glasses of red wine
Preheat your oven and an appropriately sized roasting pan to 230°C/450°F/gas 8. (If I make it ahead, I skip pre-heating the pan, but make sure to bring the meat and pan to room temperature before roasting).
Make sure there are no gaps in between the laid-out slices of prosciutto. Chop one of the garlic cloves and fry with the soaked porcini in 1 pat of butter for a minute. Then add half of the soaking water (make sure it is grit-free). Simmer slowly and reduce for around 5 minutes before stirring in a squeeze of lemon, the remaining 2 pats of butter and seasoning. Rub your tasty and moist mushrooms over half of the laid-out prosciutto. Season your fillet of beef with salt & pepper, and roll it in the herbs. Place it on the mushroomy end of the prosciutto and slowly roll up the meat. Once the beef is rolled up, pull off the paper and push in the ends of the prosciutto to neaten. Lightly secure with 4 pieces of string (I use Food Loops, which are so handy!).
Place the fillet in the hot roasting tray with a couple of cloves of garlic and cook for 25-30 minutes (rare), 40 minutes (medium), 50 minutes (well-done) or 60 minutes (cremated!). Half-way through, add the wine to the pan. When the meat is done, remove it to a chopping board and leave it to rest for 5 minutes. Pour any juices back into the roasting tray. Simmer the juices on the stovetop, scraping all the goodness from the sides of the pan, and mash up the garlic cloves. Remove from the heat and serve as a light red wine gravy.
Slice the fillet as thick or as thin as you like and serve with some potatoes or some gorgeous greens.
