Steak Diane

What to expect

Taste

Rich, sharp and boozy, in that order. The cream is the volume and the mustard is the structure — a tablespoon of Dijon in a small pan sauce is assertive, and its sharpness is what keeps the cream from being merely heavy. Worcestershire brings a fermented, anchovy-backed savouriness that is doing more than most people notice. The brandy leaves a distinct warm sweetness even after burning, and it is worth knowing that the flame removes far less alcohol than people assume — most of what burns is vapour above the pan, and a good deal stays in the sauce. Mushrooms are earthy and are the only vegetal note. Shallots are sweeter and gentler than onion. And the beef itself is mild: fillet is the most tender cut and among the least flavourful, which is exactly why it gets a sauce like this.

Aroma

Butter browning first. Then mushrooms, which smell of very little until they start to colour and then smell strongly. The brandy going in produces a sharp alcoholic hit that changes character the moment it lights — burnt sugar and warmth. Mustard and Worcestershire are pungent for a moment when they hit the pan. Cream mutes everything and the finished dish smells rich and slightly sweet.

Texture

Very tender meat with a browned crust, in a smooth sauce with soft mushrooms through it. There is almost no textural contrast, which is why chips or a crisp salad matter. Fillet beaten to a centimetre and cooked ninety seconds a side is about as tender as beef gets.

Sound

The dish is loud for fifteen minutes. Butter foaming, then the steaks hitting a hot pan, then the mushrooms squeaking and then quietening as they release water. The brandy going into a hot pan hisses violently. And the flame itself has a low soft roar for a few seconds, which is the sound the whole tableside tradition was built on.

How the flavour moves

Mustard first and sharply. Then cream spreading across the mouth, then the savoury Worcestershire depth. The brandy's warmth arrives late and stays. Beef is present throughout and is not the loudest thing on the plate — which is either the dish's weakness or the reason it exists, depending on your view of fillet steak. The finish is rich, sharp and quite long.

Serve it

Hot, on warm plates, immediately. Cream sauces cool fast and go claggy, and a cold plate ruins the dish in a minute.

Goes with

Chips, or mashed potato, or plain boiled new potatoes. A sharply dressed green salad, which is what the plate actually needs — there is no acid in the sauce beyond the mustard. A red with some structure: a Rhône, a claret, a Barolo. Where it fails is with anything else creamy, and with delicate wine, which the mustard and brandy both overwhelm.

Cook's notes

Difficulty

Easy in execution and quick enough that everything has to be ready before you start. There is nothing difficult in it; there is also no point at which you can stop and think.

Cost

High. Fillet steak is the most expensive thing in the collection and there is no way round it, though the pieces are small.

Equipment

A wide heavy frying pan, cling film and a rolling pin for flattening, and a warm plate. A long match or a lighter if your hob is electric and cannot light the vapour.

When to make it

Anniversaries, birthdays, and any evening that wants an event. Year-round.

Best season

None.

You know it is done when

The steaks should be deep brown on both faces and pink through the middle. The mushrooms are ready when they have given up their liquid and started to colour — they go through a wet stage first and browning only begins after that. The sauce is right when it coats the back of a spoon and a finger drawn through leaves a clean line.

And it feels like

The steak should be springy rather than soft or firm. It will carry on cooking on the warm plate and again when it goes back into the sauce, so take it out slightly under.

Food safety

This is the one recipe here with a real fire risk and it deserves plain language. Take the pan off the heat before adding the brandy — a stream of spirit poured into a flaming pan can ignite back up into the bottle. Never lean over the pan when lighting it. Tilt it away from you. Keep a lid within reach, since dropping a lid on is how you put a pan fire out. Do not do it under an extractor fan running on full or beneath low cupboards. If in any doubt, skip the flame entirely — simply boil the brandy off for thirty seconds, which achieves nearly the same thing.

Where it goes wrong

Adding the brandy to a pan on the heat, which is the dangerous one. Not beating the steaks thin, so ninety seconds a side leaves them raw. Crowding two steaks into a small pan, which steams them. Boiling the cream, which splits it. Under-cooking the mushrooms, so they are still wet and dilute the sauce. And forgetting to add the resting juices from the plate back into the pan, which is a real loss of flavour.

If it does go wrong

Sauce split: it boiled — take it off the heat and whisk in a splash of cold cream, which often brings it back. Sauce thin: reduce it another minute before the steaks go back in. Steaks overcooked: they were too thick, or they went back into the sauce for too long — one turn is all they need. Brandy will not light: the pan was too cool, or the spirit is under about 40 per cent. Warm the brandy in a ladle first, or skip it and boil it off instead. Too sharp: a little more cream. Flat: more Worcestershire.

Making it ahead

Almost nothing, and it is a fifteen-minute dish. The shallots and mushrooms can be chopped ahead, and the steaks can be beaten out and kept covered in the fridge for a few hours.

Keeping it

It does not keep. The steak overcooks on reheating and the sauce splits.

Reheating

No.

Freezing

No.

Leftovers

None expected from a dish for two.

Scaling it

Badly. Four steaks will not fit in one pan without steaming, and the sauce is built in the fond the steaks leave behind, so cooking in batches means the second pair get a better sauce than the first. It is a dish for two.

Substitutions

Sirloin works and is a third of the price — it has more flavour and less tenderness, and beaten thin the difference in tenderness matters much less. Cognac is the classic spirit and any decent brandy does the same job; whisky makes a different and good dish. Crème fraîche instead of double cream gives a sharper sauce and is less traditional. There is no substitute for the Dijon, which is the backbone of the sauce.

Dietary swaps

Not adaptable. Contains milk, mustard and sulphites, all declared. Gluten-free depending on the Worcestershire sauce, which usually contains malt vinegar and therefore barley.

Shopping for it

Steak from a butcher rather than a tray, and ask for it cut thick so you can beat it out. Real Dijon. A brandy you would drink, since a bad one leaves a harsh note the flame does not remove.

Keeping the cost down

Use sirloin or rump instead of fillet, beaten thin. Beaten to a centimetre and cooked in ninety seconds, the textural advantage of fillet largely disappears and the flavour advantage of sirloin remains — this is one of the few places where the cheaper cut is arguably the better choice. That change alone takes about two thirds off the cost of the dish.

Sustainability

Beef is the highest-impact ingredient in this collection and fillet is a small part of a large animal. Using a cheaper cut is better on every axis including this one.

Nutrition

Around 720 calories a serving. Fillet is one of the leanest cuts of beef; the calories are almost entirely the butter and the double cream. It is high in protein, iron and B12.

Worth it?

Worth it, and worth doing with sirloin. The dish is a genuinely good pan sauce and a genuinely good piece of theatre, and it takes twenty-five minutes. The one thing to take seriously is the brandy: pan off the heat, tilt it away from you, lid within reach. Everything else is easy.

Where it comes from

Origin

The name and the sauce are French and nineteenth-century. The dish as it is now made is mid-twentieth-century American restaurant cooking.

Also called

Steak Diane. The ancestor is sauce à la Diane, sometimes filet de chevreuil à la Diane — venison.

Said out loud

As it looks in English. In French, dee-AHN.

What the name means

After Diana, the Roman goddess of the hunt. The original sauce was for game, and the name survived the switch to beef, which is why a dish with no connection to hunting carries a hunting name.

History

Sauce Diane appears in classical French cookery as a game sauce — Escoffier includes a version, built on a peppered poivrade with cream. The tableside beef dish is a later and different thing: it belongs to the era of the trolley and the gueridon, when restaurants competed by finishing dishes in front of the customer, and it sits alongside crêpes Suzette, steak au poivre and bananas Foster as a piece of dining-room theatre. Both the Drake Hotel in New York and the Colony Restaurant have been credited with popularising it in the 1940s and 1950s, and the claims are repeated more often than they are evidenced.

Why it matters

It is the dish that stands for a whole style of restaurant that has largely disappeared — the trolley, the maître d', the flame, the performance. Its decline and its intermittent revivals track the fortunes of that style rather than anything about the food, which was always good.

When it is eaten

Anniversaries and dinners for two. It is a dish for an audience of one or two and it makes no sense cooked for eight.

The traditional way

The flambé, and it is worth being clear about what it does. Burning the alcohol produces a brief very high heat at the surface that caramelises sugars and creates flavour compounds, and it burns off some of the harsh raw-spirit edge. What it does not do is remove most of the alcohol — a fair proportion remains, and studies of flamed dishes have found substantial alcohol left behind. So it is partly chemistry and substantially theatre, and both of those are legitimate.

How it changed

It went from venison to beef, from a French sauce to an Anglo-American one, and from a kitchen dish to a tableside one and back again. Mushrooms are a later addition and are now near-standard.

Regional variations

Australia has an unusually strong attachment to it and it remains a pub and bistro standard there in a way it is not elsewhere. Some versions use sherry rather than brandy, some add lemon juice, and the mustard-to-Worcestershire ratio is where cooks disagree.

How this version differs

It is a fairly standard modern build. Where it is more explicit than most is on the safety of the flambé, which is the one genuinely hazardous step in this collection and is usually written as though it were a flourish.
