Sous vide cooking gives you a high level of control over temperature and cooking. This is particularly useful in a professional kitchen. You can prepare dishes precisely and easily achieve consistent results. With sous vide, you can prepare meat, fish, vegetables and more in sealed packaging. The food cooks slowly in water at a constant temperature. This ensures even cooking and helps you plan your mise en place more efficiently.
In this guide, you’ll learn how sous vide works, what equipment you need and what to look for when choosing a sous vide machine.
What is sous vide cooking?
Sous vide literally means ‘under vacuum’. With this cooking technique, you place ingredients in a suitable vacuum bag. You then cook them in a water bath at a precisely controlled temperature.
The main advantage is the level of control you have over the cooking process. The food never becomes hotter than the water around it. This allows you to control the desired level of cooking very precisely.
Sous vide is suitable for many different ingredients, including beef, pork, chicken, fish and a variety of vegetables. This technique is also practical when preparing larger quantities. For restaurants, catering businesses and other professional kitchens, sous vide makes it easier to achieve consistent results.
How does a sous vide machine work?
A sous vide machine heats water to a set temperature. It then keeps the water at this temperature as consistently as possible. Many sous vide systems also circulate the water, helping to maintain an even temperature throughout the water bath.
The process usually consists of four steps:
- prepare and season the ingredient
- place the food in a suitable vacuum bag
- set the required time and temperature
- leave the food to cook evenly
After cooking, you can briefly grill or sear meat, for example. This adds colour and creates a browned exterior.
What equipment do you need for sous vide cooking?
For sous vide cooking, you need a precisely heated water bath. You also need suitable packaging.
The main items you need are:
- a sous vide stick or complete sous vide machine
- a suitable water container
- food-safe vacuum bags
- a vacuum packing machine or vacuum sealer for professional use
Sous vide stick
You place in a suitable water container. The stick heats the water and keeps the temperature stable.
A stick is particularly useful if you:
- want the flexibility to use different containers
- have limited storage space
- want to use sous vide at different workstations
Sous vide machine
has its own water container. The heating system and temperature controls are integrated into the machine.
This can be a practical choice if you:
- regularly cook sous vide
- have a permanent workstation
- want a complete system that is quick to set up
Vacuum packing machine or vacuum sealer
Good vacuum packing is important for professional use. A or removes air from the packaging.
This offers several advantages:
- portions are easy to prepare in advance
- food is securely sealed
- you can work more efficiently with larger quantities
- your mise en place stays organised
Sous vide stick or sous vide machine: which should you choose?
There is no single best sous vide machine for every kitchen. The right choice depends on how you work. Do you only use sous vide occasionally and want to stay flexible? A sous vide stick can be a good choice. Do you work with sous vide every day? A complete machine with a fixed water container may be more practical.
When choosing your equipment, consider:
- capacity
- power
- temperature range
- accuracy
- ease of use
- cleaning
- available workspace
- how often you will use it
What can you cook sous vide?
Sous vide is suitable for many different foods. Our chef lists some of the most common options below:
Meat
Steak, lamb and pork can be cooked very evenly. You can accurately control the desired core temperature. After cooking in the water bath, briefly sear the meat for extra colour and flavour.
Fish
Fish often requires careful temperature control. Sous vide helps you cook it evenly without exposing it to unnecessarily high temperatures.
Poultry
You can also prepare chicken, turkey and duck sous vide. This can be useful when you want to prepare several portions in advance.
Vegetables
Many vegetables are suitable for sous vide cooking. The controlled cooking process gives you more control over their texture and flavour.
For professional kitchens, sous vide can be particularly useful for:
- mise en place
- batch cooking
- catering
- buffets
- preparing for busy service periods
What are the advantages of sous vide?
One of the main advantages is consistent quality. If you use the same temperature, cooking time and quantity, it is easier to achieve the same result every time.
Other advantages include:
- less moisture loss during cooking
- more control over the desired result
- more efficient preparation
- less attention required during cooking
- the ability to prepare several portions at the same time
Sous vide can also make kitchen planning easier. You can spread preparation tasks more evenly throughout the day, giving your team more time for other jobs during busy service periods.
What are the disadvantages of sous vide cooking?
Sous vide cooking may not suit every kitchen, and there are a few points to consider:
- longer cooking times
- additional equipment
- an extra vacuum packing step
- no crispy exterior without finishing the food afterwards
- careful temperature control and food safety are essential
However, a longer cooking time does not have to be a problem. You can use this time for other tasks. With good planning, sous vide can therefore add significant value to your mise en place.
What is the difference between sous vide and a slow cooker?
A slow cooker is not the same as sous vide. The main differences are:
- with sous vide, the food is placed in sealed packaging
- with a slow cooker, the food is placed directly in pan
- sous vide focuses on precise temperature control
- a slow cooker is mainly designed for cooking food slowly
A slow cooker is therefore not automatically a suitable replacement for a sous vide machine.
Can you cook sous vide in a saucepan or conventional oven?
You can use a standard saucepan as a water container. However, you still need a sous vide stick to control the temperature. Without accurate temperature control, it is difficult to keep the water at the same temperature for a long period.
works differently from a sous vide water bath. It therefore usually does not offer the same level of control around the packaged food.
For daily professional use, dedicated sous vide equipment offers several advantages:
- temperature control
- reliability
- consistent results
- ease of use
Can you cook sous vide without a machine?
In theory, you can try to keep a water bath at the correct temperature yourself. In practice, this requires a lot of monitoring. A difference of just a few degrees can affect the result.
Manual temperature control may be possible for occasional use. For professional applications, a sous vide stick or machine is more practical.
This gives you:
- more stable temperatures
- less manual monitoring
- more consistent results
- a more efficient workflow
Can you cook sous vide without a vacuum packing machine?
There are ways to remove air manually from a suitable bag. This can work for some simple applications.
For a professional kitchen, a vacuum packing machine offers more advantages:
- faster packaging
- consistent results
- neatly portioned food
- securely sealed packaging
- more efficient preparation of larger quantities
Can you cook sous vide without a plastic vacuum bag?
Sous vide requires packaging that seals the ingredient properly and is suitable for heating. Not every bag or type of packaging can be used for this purpose.
Always check whether the material is suitable for:
- food contact
- the selected temperature
- the cooking time
- the vacuum packing method you use
Is sous vide cooking healthy?
Sous vide can fit well into a balanced approach to food preparation. Many dishes require very little additional fat. The ingredients remain sealed during cooking, which keeps moisture and flavour inside the packaging.
For safe professional use, always pay attention to:
- the correct cooking temperature
- sufficient cooking time
- hygienic working practices
- quick and correct cooling
- correct storage
