Gastronomy experts are well aware of the benefits of slow cooking food. Utensils such as the Roner or slow-cookers make this task easier, as they allow for slow and gradual cooking. Thanks to this, juicy and tender dishes with all their flavor are obtained. The traditional slow cooking is back, but improved with new technologies.
The Roner, also called “sous vide” (vacuum, in French), are appliances designed to cook sous-vide and bain-marie foods. Although they are mainly used in restaurants, in recent years they are reaching more and more home kitchens. Their versatility allows you to prepare a wide range of recipes.

Created in 1999 by two great Spanish chefs, the Roner has become one of the most popular kitchen utensils in recent years. With this small appliance it is possible to cook food under vacuum so that it retains all its texture and flavor. There are different types, although the best-selling is the immersion thermocirculator or the Roner clip.
The Roner is a device with multiple advantages. It is easy to use and is able to prepare food almost without our intervention. Sometimes they are mistaken for slow cookers, but they have little to do with them. To use it it is essential to use specific vacuum bags for cooking of this type.

Shopping Guide: Everything you should know about the Roner

Roners are kitchen utensils designed to prepare food slowly, so that it retains all its flavor, aroma and texture. Find out more in this section!
How does a Roner work?
What are the advantages of vacuum cooking done with the Roner?
Below we have prepared a list of the many benefits of sous-vide cooking with a Roner:
- Preserve the flavor of food. When food is vacuum-cooked, it retains all its juice and flavor. Have you ever noticed that the meat shrinks in the pan? This happens because it ‘dries out’, losing its original texture and flavor. Cooking it with a Roner won’t happen.
- Store all nutrients. Foods prepared with a Roner not only do not lose their texture, smell and taste, but also retain their nutritional properties. This is because it is not necessary to reach high temperatures, which affect nutrients more.
- Healthy cooking. Sous-vide cooking will allow you to use much less oil and salt. Vegetables, for example, will retain all of their vitamins and minerals and will be naturally seasoned and tastier.
- They keep for longer. Vacuum-packed meat, fish and vegetables can be stored in the bag in which they were cooked. In addition, they can be frozen for several months, depending on the food.
- Saving of kitchen utensils. With a Roner you only need a water container and a vacuum machine to prepare tasty dishes.
- Reliability. The Roners allow extremely precise control of the temperature and cooking times of food. Thanks to this, the same recipe will always taste the same tasty as long as you keep the same time and the same temperature.
- Time savings. While the Roner prepares food, you can do other activities. There is no need to mix, add ingredients or pay attention to cooking. And if the roner has a wireless connection, you can check it even when you are away from home.
- It’s convenient. Nowadays you can find a good Roner for under € 70. As for vacuum packaging machines, they can cost less than € 40.
How many types of Roner are there?
There are basically three types of Roner. The first type – the domestic one – is a device that keeps the water temperature controlled by a thermostat, while it recirculates the water in the container. The food is thus cooked evenly.
The “sous-vide” ovens, on the other hand, integrate a baking tray and unlike immersion thermocirculators, the food is immersed inside the appliance. Generally, they are easier to use than immersion Roners, but their capacity is lower, they take up more space and are more expensive. They are usually intended for use in restaurants and the like.
The Rocook is the third type of Roner. It is a small induction cooker with two thermometers: one to measure the temperature of the water, or another liquid, and the other to measure the temperature of the food. With this utensil it is not mandatory to cook vacuum packed food.
What accessories do you need to cook with a Roner?
To prepare food with a Roner you will need a suitable container. You can use any pot or saucepan as long as the Roner can be securely attached to the walls. All Roners have two signs: the minimum and maximum water level. The container, therefore, must be deep enough to immerse the Roner between the two levels.
They are usually plastic containers of different capacities, equipped with a lid with a slot to insert the Roner. There are also tools to place the bags inside these containers, so that they are completely submerged and cook properly.
The vacuum packaging machine is the only essential accessory for cooking with the Roner. The best are the electric ones, but there are also sufficiently effective manuals. Either way, you will need food-grade plastic bags or rolls to put the food in. They must be special to the Roner and be free of substances that are harmful to health, such as BPA (bisphenol A).
Which container is most suitable for cooking with the Roner?
When buying a Roner, it is common to use one of the metal pots or pans you have at home. However, these aren’t not ideal. Metal is an excellent conductor of heat, which is why much of it radiates from the container we are using. In addition, this cookware usually does not have a lot of capacity, so after introducing the Roner there is not much room left for food.
They are designed to be used with a Roner and are usually not expensive. Their capacity is much greater than that of a home cooking pot and, in addition, you will be able to observe how the food cooks, as they are transparent. Some have grids and dividers for placing bags.
What kind of upkeep does a Roner require?
Being in contact with hot water and steam, Roners are among the appliances that can be most affected by the impact of these. As the water evaporates, the limescale it contains gradually adheres to the appliance and can cause the turbine to slow down or block. To avoid this we must subject the Roner to the periodic descaling recommended by the manufacturer.
