Mushroom Julienne

What to expect

Taste

Deeply savoury and rich — mushrooms cooked down to concentrate their own flavour before anything else joins them, wrapped in a sauce that's both creamy from the bechamel and gently tangy from the smetana, with melted Gruyere adding a final salty, nutty layer on top. The onion, cooked soft with no colour, contributes sweetness rather than sharpness.

Aroma

Deeply savoury, cooked mushroom first — earthy and slightly meaty — then the warm, milky smell of the bechamel and the sharper, toasted note of the browned cheese once it comes from under the grill.

Texture

Thick and creamy, coating a spoon rather than running off it, with the julienned mushrooms still offering a little bite against the smooth sauce around them — the browned cheese top adds a contrasting, slightly crisp layer over the soft interior.

Sound

A quiet bubble at the edges of the dish as it comes out of the oven, and the specific sizzle of cheese browning under a hot grill.

How the flavour moves

The browned cheese arrives first on the spoon, salty and slightly nutty, giving way to the rich, tangy sauce underneath, with the mushrooms' deep savoury flavour the last thing to register as the main body of the mouthful.

Serve it

Served properly hot, and genuinely dangerously so straight from the grill — the rest period is functional rather than a suggestion.

Goes with

Bread on the side for mopping the sauce once the mushrooms are gone, and a green salad or pickled vegetables to cut through the richness of the dish as a whole.

Cook's notes

Difficulty

Easy, with one point of real technique: getting the mushroom pan back to fully dry before any sauce goes near it.

Cost

Cheap to moderate — mushrooms, a modest bechamel, smetana and a hard cheese for the top.

Equipment

A wide frying pan, four small ovenproof dishes or ramekins (traditionally a kokotnitsa, a small metal dish with a long handle), and a grill.

When to make it

As a starter for a dinner party or celebration, or scaled up as a light main course with bread and salad.

Best season

None — mushrooms are available year-round.

You know it is done when

The mushroom pan should look properly dry and be sizzling in fat rather than simmering in liquid before any sauce is added; the finished dishes should be bubbling at the edges with the cheese browned in patches on top.

And it feels like

The sauce should hold its shape on a spoon rather than running, and the mushrooms should still have some bite left rather than having cooked down to nothing.

Food safety

Nothing beyond ordinary hygiene; the dishes come out of the oven and grill genuinely very hot and need a real rest before eating.

Where it goes wrong

• Adding the sauce before the mushroom pan is properly dry, which leaves a thin, separated, greyish result under the grill.
• Slicing rather than cutting the mushrooms into matchsticks, which loses the bite the julienne cut is specifically there to preserve.
• Boiling the soured cream once it's been added, which splits it into curds and whey with no way back.
• Serving straight from the grill without the short rest, when the sauce is genuinely too hot to eat safely.

If it does go wrong

Thin, separated sauce: the mushrooms weren't cooked fully dry before the sauce went in. Split, grainy texture: the soured cream was returned to direct heat after being stirred in. Bland result: under-seasoned at the mushroom stage, before the rich sauce masks it.

Making it ahead

The mushroom-and-sauce mixture can be made ahead and refrigerated, then divided into dishes, topped with cheese and baked fresh closer to serving.

Keeping it

A day or two refrigerated, though the texture of the sauce is at its best freshly grilled.

Reheating

A low oven to warm through gently; a grill alone will brown the top again but not necessarily heat the middle.

Freezing

Not ideal — the bechamel-and-cream sauce doesn't freeze and thaw cleanly.

Leftovers

Best eaten within a day or two rather than kept longer, given the dairy-heavy sauce.

Scaling it

Scales easily by making more individual dishes; there's no real advantage to combining it into one large dish, since the point is a portion each.

Substitutions

Older Soviet restaurant recipes used soured cream thickened with a little flour rather than a full bechamel, giving a sharper, thinner sauce than the richer version here; either is legitimate depending on how heavy a dish is wanted. Any good melting hard cheese can stand in for Gruyere.

Dietary swaps

Vegetarian as written. Contains milk throughout, from the butter, bechamel and smetana as well as the cheese, so a dairy-free version would need substantial reworking of the sauce rather than a simple swap. Naturally gluten-free apart from any flour in the bechamel, which could be made with a gluten-free flour blend.

Shopping for it

A good melting hard cheese with real flavour — Gruyere or a similar alpine-style cheese — makes a noticeable difference to the browned top.

Keeping the cost down

Ordinary button or chestnut mushrooms keep this cheap; the cheese and cream are where any real cost lies.

Sustainability

A modest, low-waste dish using inexpensive, widely available mushrooms as its main ingredient.

Nutrition

A rich, dairy-heavy starter rather than a light one, given the combination of butter, bechamel, smetana and cheese.

Worth it?

A genuinely satisfying, quick-to-assemble starter, and a small lesson in how a single word can mean two completely different things once it crosses a language.

Where it comes from

Origin

Russia, during the period when professional kitchens there worked substantially in French culinary vocabulary.

Also called

Zhulyen (жюльен), a Russian transliteration of the French julienne.

Said out loud

zhoo-lee-YEN, following the French pronunciation of the borrowed word.

What the name means

In French, julienne names only a knife cut — thin matchstick strips. In Russian the word was carried over as the name of this specific finished dish rather than the cut alone, which is a genuine divergence in meaning between the two languages rather than a mistranslation in the usual sense.

History

French-trained chefs and French culinary fashion were highly influential in Imperial Russian restaurant kitchens, which is the route by which a French knife-cutting term ended up naming a Russian baked dish. No individual chef or specific origin date is documented for zhulyen in its current form.

Why it matters

A standard restaurant starter across Russia and the former Soviet states, and also a common New Year and celebration dish cooked at home — four portions scale easily into a light main course with bread and a salad alongside.

When it is eaten

Restaurant starters and New Year's celebrations especially, though it appears as an everyday dish too.

The traditional way

Mushrooms cut into fine matchsticks and cooked until fully dry, combined with a cream-based sauce, and baked and grilled in individual dishes rather than one shared one.

How it changed

Older Soviet-era versions more often used soured cream thickened lightly with flour rather than a full French-style bechamel, giving a sharper, thinner sauce than many modern versions; the fuller bechamel-based version is a later, richer evolution.

Regional variations

A chicken version, zhulyen s kuritsey, using poached chicken alongside or instead of mushroom, is at least as widely made as the plain mushroom version.

How this version differs

This recipe uses a proper warm bechamel finished with smetana off the heat, rather than the thinner, flour-thickened soured cream of older Soviet versions.

Sources and credit

No individual chef or restaurant can be credibly credited with inventing zhulyen; it belongs to a broader period of French-influenced Russian restaurant cooking rather than to any one named figure.
