Quick answer: A sous chef (from the French for “under-chef”) is the second-in-command of a professional kitchen. The role sits directly below the head chef and above the chefs de partie, and runs the kitchen day to day: the pass during service, the rota, ordering, the food safety records, and the rest of the cooking team.
“Sous” turns up on kitchen rotas, job adverts, and agency booking sheets as the rank everyone assumes you already understand. It is the seat Chefs Bay is asked to cover the moment a head chef calls in sick or hands in their notice, because a kitchen can lose almost any other role for a shift and still serve, but it cannot lose the person running the pass. This guide sets out what a sous chef actually is, where the role sits, what the job involves on a real shift, what it pays in 2026, and the route into it.
What does sous chef mean?
Sous chef is French. “Sous” means “under” and “chef” comes from the word for “chief” or “head”, so the full title, sous-chef de cuisine, translates as “under-chef of the kitchen”. In plain terms the sous chef is the head chef’s deputy: the second-in-command who runs the kitchen day to day and takes it over outright when the head chef is off.
The English word has been in use since at least the late nineteenth century, with Merriam-Webster dating its first appearance to 1892. The job has carried roughly the same meaning ever since, because it comes from the brigade de cuisine, the kitchen staffing system Auguste Escoffier set out in the early twentieth century and still the default structure in UK hotels, restaurants, and large contract kitchens.
Several titles describe the same rank. “Second chef” and “deputy chef” are the common English versions. Larger kitchens split the role by seniority: a junior sous chef is the first step into kitchen management, a senior sous chef carries the heavier administrative load and runs the kitchen in the head chef’s absence, and an executive sous chef sits at the top of that band in big hotel brigades. The prefix changes the scope. The core job, running the kitchen under the head chef, does not.
Where a sous chef sits in the kitchen brigade
The brigade is a ladder, and the sous chef sits one rung below the head chef and one above the chef de partie. The order runs commis chef, demi chef de partie, chef de partie, sous chef, head chef, with an executive chef above the head chef in larger operations.
Whether the sous is “second” or “third” in command depends on the kitchen. In a pub or single-site restaurant with one head chef at the top, the sous chef is second-in-command, full stop. In a hotel that runs an executive chef over a head chef, the sous sits third. Both are right; they describe different sized kitchens, which is why job adverts and dictionaries seem to disagree.
Once a kitchen is big enough, the sous role itself splits into tiers:
| Tier | Where it sits | What they run |
|---|---|---|
| Junior sous chef | Above senior CDP, below sous | The pass on quieter services; daily prep lists; coaching the CDPs while training for full sous |
| Sous chef | Directly below head chef | The line and the team day to day; the pass at service |
| Senior sous chef | Top of the sous band | The whole kitchen in the head chef’s absence: rota, gross profit, compliance |
| Executive sous chef | Largest hotel brigades | A full kitchen reporting up to an executive chef across multiple outlets |
For the full brigade, and where commis, demi, and chef de partie fit below the sous, our chef de partie guide covers the rest of the ladder.
What a sous chef does day to day
Strip out the textbook language and a sous chef’s day is logistics, compliance, and people management wrapped around a service.
The core of the job at service is running the pass. The pass is the line between the kitchen and the dining room, and the sous chef stands at it: reading the tickets, calling dishes to each section, checking every plate for temperature and accuracy, and controlling the timing so a table’s food leaves together. Get the pass wrong and service backs up, food goes cold, and the complaints start. Holding it calmly through a full Saturday is the skill the rank is really hired for.
Around service sits the rest of it. The sous sets the prep lists the chefs de partie work to, runs the line check before doors open, places the daily orders, and keeps portion and waste control tight because that protects the kitchen’s gross profit. They build the rota, manage the junior chefs through the shift, and train the commis and CDPs. And they own the food safety paperwork: HACCP logs, temperature records, and, since Natasha’s Law, the allergen matrix that tells every chef exactly what is in each dish. In care home and school kitchens that paperwork is inspected, so it is a genuine part of the job rather than an afterthought.
What the day actually looks like depends on the size of the kitchen. In a 40-cover gastropub the sous is on the tools: cooking the hardest section, covering the head chef’s day off, doing the ordering, and locking up at the end. In a 200-cover hotel the volume makes that impossible, so the sous steps off the stove at service and works the pass full time, timing six sections and a room full of waiters. Plenty of small, single-service kitchens run with no sous at all, the head chef holding the pass alone. The title is the same; the shift is not.
Sous chef vs head chef vs chef de partie
The ranks blur from outside the kitchen, so here is the practical split by what each one owns.
A head chef owns the menu and the numbers. They design the dishes, cost them, set the gross profit target, choose the suppliers, and hire and fire. The work is as much office as stove, and the accountability for whether the kitchen makes money is theirs.
A sous chef owns the execution. They turn the head chef’s menu and standards into a service that runs, day after day: the pass, the prep, the orders, the compliance, the team on shift. A sous can run all of that for days or weeks while the head chef is away, which is exactly why interim sous cover works during a head chef recruitment. What a sous does not carry is the long-term ownership, so a booking that genuinely needs menu development and costing should be priced at head chef level, not sous.
A chef de partie owns one section. They prep and cook their station, whether that is sauce, fish, grill, larder, or pastry, and answer for its output, but their responsibility stops at the edge of that section. The sous sets the standard they work to and checks it before service. For the detail on that rank, our chef de partie guide covers it, and venues booking section cover through an agency are always asked to name the station, not just the role.
What a sous chef earns in 2026
Two numbers matter here, and they are different: what a sous chef is paid, and what an agency sous chef costs a venue.
Permanent pay first. The UK average for a sous chef sits around £34,000 a year, with Indeed UK reporting £33,919 across 18,600 salaries in June 2026, rising to roughly £37,500 in London. Job-board averages spread widely, from the high £20,000s to the high £30,000s, because they fold old contracts in with current vacancies, so treat any single figure as a starting point rather than a quote.
Agency sous chefs are paid by the hour, through PAYE, at roughly £17 to £24 an hour in 2026, with London and premium event work at the top of the band. That hourly rate runs above the permanent equivalent because agency shifts carry no guaranteed hours.
That is the short version, kept short on purpose. The full salary tables by role and region, and the employer on-costs that turn a salary into a true cost to employ, are in our 2026 UK chef salary guide. If you are a venue working out what agency cover costs rather than what the chef takes home, that is a separate calculation set out in the UK chef hire rate benchmark 2026, and the day-rate detail by role is in our temp chef rates guide.
The career path: commis to sous to head
Nobody starts as a sous chef. The standard route runs commis chef, then chef de partie, then sous, and UK kitchens generally want three to five years on the line before they hand someone the rank. The full route from commis can take closer to seven years. The reason is simple: a sous has to be able to step onto any section and rescue it, and you cannot supervise a sauce station you have never run yourself.
Qualifications help but rarely decide it. The relevant ones are the City and Guilds NVQ Diplomas in Professional Cookery at Levels 2 and 3, or a chef apprenticeship, and the Level 3 diploma names sous chef as a target outcome. In practice most kitchens promote on demonstrated ability over a certificate, and an experienced CDP will beat a fresh graduate for the seat. The one hard requirement is a food safety certificate, usually Level 2 and increasingly Level 3 for the chef supervising the kitchen.
From sous, the next step is head chef. A strong sous who can already run the kitchen unsupervised, hold the gross profit, and lead the team is most of the way there. What remains is the menu and the commercial ownership.
When a kitchen needs a sous chef
There is no cover count that triggers it, whatever the job boards imply. The real test is whether one person can hold the kitchen alone.
A small kitchen running one service a day off a short menu can work with a head chef and a couple of chefs de partie; adding a sous would put labour cost on without adding output. The case for a sous appears when the kitchen runs multiple sections at once, two services a day, or seven days a week. At that point the head chef cannot be on the pass for every service and still take a legal day off, and a kitchen with no deputy has a single point of failure: the day the head chef is ill, nobody can run it. The sous is the cover that keeps the operation going.
Booking sous chef cover, or looking for sous work?
If you run a kitchen and you are short a sous, the reason is usually one of a few. Sickness is the single biggest trigger and the most sudden. Maternity and paternity cover drives the longest bookings, often six to twelve months. Holiday cover tends to be booked four to eight weeks ahead. And when a head chef leaves, the permanent sous is often promoted to act up, which opens the sous seat for an interim while the recruitment runs.
Whichever it is, our sous chef hire page sets out response times, rates, and how interim, holiday, and temp-to-perm cover work, including the two-hour response commitment for central London, Manchester, and Liverpool postcodes. A relief booking that needs full menu ownership is a head chef booking, and we will say so on the call rather than send a sous into a gap they cannot fill.
If you are a chef, agency sous work is a fast way to see how different kitchens run and to build toward head chef. Our sous chef jobs page shows what the shifts pay, and you can register as a chef in a few minutes; most candidates are approved within 48 hours of sending their documents. Sous cover comes up across hotels and restaurants, contract catering sites, care homes, and schools, often with steadier hours than à la carte service.
Frequently asked questions
What does sous chef mean?
Sous chef is French for “under-chef”, short for sous-chef de cuisine, “under-chef of the kitchen”. It is the second-in-command of a professional kitchen, the rank directly below the head chef and above the chefs de partie. The sous runs the kitchen day to day and takes full charge when the head chef is away.
Is a sous chef higher than a chef de partie?
Yes. A sous chef is one rank above a chef de partie. A CDP runs a single section of the line; the sous runs the whole line and the chefs de partie on it, sets their prep lists, checks their sections before service, and takes the pass. A strong CDP is usually two to three years from stepping up to sous.
What is the difference between a sous chef and a head chef?
The head chef owns the menu, the costing, the suppliers, and the hiring; the sous chef runs the daily execution and deputises. A sous can hold service, ordering, and compliance for days or weeks, which is why interim sous cover works while a head chef is recruited. Menu development and long-term commercial ownership stay at head chef level.
Is a sous chef second-in-command?
In a kitchen with a single head chef at the top, yes, the sous chef is second-in-command. In a larger operation that runs an executive chef above the head chef, the sous sits third. The rank is the same; the number just reflects how many tiers sit above it.
How long does it take to become a sous chef?
Most UK kitchens expect three to five years on the line before promoting to sous, and the full route from commis can take closer to seven years. There is no mandatory qualification for the rank, though a food safety certificate is required to work as a chef. Kitchens promote when a chef can run any section and lead a service unsupervised.
What is a junior sous chef?
A junior sous chef is the first step into kitchen management, sitting between senior chef de partie and full sous chef. They run the pass on quieter services, manage prep lists, and coach the chefs de partie while learning to take the kitchen on. Larger hotel brigades use the rank; smaller kitchens promote straight from CDP to sous.
Do you need qualifications to be a sous chef?
Not by law. The useful qualifications are the City and Guilds NVQ Diplomas in Professional Cookery at Levels 2 and 3, or a chef apprenticeship, but most kitchens promote on demonstrated experience rather than certificates. The one hard requirement is a food safety certificate, usually Level 2 and often Level 3 for the chef supervising the kitchen.
