Steak with Truffle & Peppercorn Sauce

20 min

I’ve wanted to create a modern take on peppercorn sauce to celebrate the fact I’ve been invited once again to be a chef judge at this year’s World Steak Challenge in Dublin. So I came up with a truffle and peppercorn sauce, but don’t worry there are ways to add a delicious truffle flavour without breaking the bank.

Earlier this year when I was at a food show I was given some new truffle products made by a company called Trufo. I used a teaspoon of Truffle Porcini sauce which is actually more like a puree; a puree of vacuum cooked porcini mushrooms, that they then add burgundy truffles too. A 50-gram jar costs a very reasonable 5.99 euros (currently £5.13). I also used a little sprinkle of a product called truffle earth to intensify the truffle flavour in the sauce.

The starting point for me is the plate, I’ve been searching for a dark coloured dinner plate for some time, then I found one I liked on the Habitat site. I tried asking their press department if I could borrow a dinner plate for the shoot, but after several emails and a voicemail to their press department which got no response, I decided to bite the bullet and buy one. Next question is should I slice the steak? Put the sauce on the side? There are lots of versions of peppercorn sauce: which will look best for photography?

The worst steak to use for pepper steak is a fillet steak (filet mignon) because the flavour of the steak is not strong enough to stand up to the peppercorns.
So I would recommend a well-aged sirloin steak (the ageing makes the steak more tender and also improves the flavour). As for size that is a personal thing but I used 10 oz (285 grams) steak that was already trimmed to my specs so it did not need further trimming.


  • Peppercorn sauce (serves 2)
  • 125 ml Beef stock
  • 1 small shallot finely diced
  • 150 ml Double cream
  • 1 Tbspoon Black Peppercorns crushed
  • 2 small chestnut mushrooms (cut in half and thinly sliced)
  • 25 g unsalted butter
  • 1 teaspoon of Truffle Porcini sauce
  • a dusting of truffle earth (optional)


Melt the butter in a small non-stick saucepan and add the finely diced shallots and cook on a medium heat for several minutes and then add the chestnut mushrooms. Turn the heat down and stir until cooked and lightly brown.
Now add the beef stock and allow to simmer for several minutes to “marry” the flavours. Next add the teaspoon of truffle porcini sauce and the 150 ml of double cream and turn the heat to low and allow the sauce to reduce down for a couple of minutes, then reserve.
Blanch the green vegetables you intend to serve with your steak and refresh in cold water, then drain and reserve.
Take a teaspoon of the crushed black peppercorns and stir into your reserved sauce. Take the remaining pepper and coat both sides of your sirloin steaks.
Cooking the Steak
People often mess up cooking steak at home because they don’t get the pan hot enough. If you have your smoke detector close to your kitchen then open a window to prevent your alarm inadvertently going off.
Get a 28 cm Non-stick frying pan hot before you put the steaks in then use a pair of tongs to hold both steaks together like a sandwich with the fat side down.
Cooking the fat first will add some flavour to the pan and give your finished steak a better appearance.
Once the fat is lightly brown then lay the steaks flat in the pan and season with sea salt.
Cook the steaks to your liking turning them just once, allow the steaks to rest on a warm plate for 5 minutes before serving.
Reheat your vegetables while your steaks are resting and pour the warm truffle and peppercorn sauce into two small bowls or ramekins.
Place the ramekins onto warm dinner plates, then sprinkle a little truffle earth onto the top of each sauce.
Suggested vegetables
Purple Sprouting Broccoli
Green Sprouting Broccoli
Sugarsnap peas
Lightly roasted pecan nuts (optional)
Chef’s Tips
If you wish to serve potatoes with the steak then I suggest you keep it simple because of the complex flavours of the sauce and steak, so a baked potato or baby potatoes will do just fine, and without butter or sour cream because you have sauce to dip them into.
Some of you might have noticed that there is no brandy (cognac) in my modern version of peppercorn sauce, this was intentional. Usually, the cognac is there to add depth of flavour, but in my sauce the porcini and truffle add plenty of flavour making the alcohol unnecessary.
