What is sous vide cooking?
Sous vide is a French cooking technique where food is vacuum-sealed and slow-cooked in low-temperature water. The term "sous vide" means "under vacuum" in French. This method, which was developed by French chefs in the 1970s, ensures food cooks evenly in its own juices, preserving moisture and tenderness.
To cook sous vide, the food is sealed in an airtight plastic pouch using a vacuum sealer, or alternatively, a heavy-duty freezer bag can be used. A circulator heats the water to a precise, low temperature and keeps it consistent throughout the cooking process, which can last from one hour to a full day. While meat dishes like steak and ribs are especially popular, chefs advise against using the sous vide technique for flaky fish or boneless poultry.

How does sous vide cooking work?
Sous vide is a French cooking technique where food is vacuum-sealed in airtight pouches, then slowly cooked in a water bath at a low temperature. This method ensures the food cooks evenly, retaining moisture and tenderness within its own juices.
Developed by French chefs in the 1970s, sous vide gained popularity in the United States thanks to chefs like Thomas Keller and Daniel Boulud. The process involves using a vacuum sealer for food-grade plastic pouches and a circulator to maintain consistent water temperature. Cooking times can vary from one hour to a whole day, depending on the food.
Sous vide is well-suited for meats like steak and ribs, as well as seafood like salmon and shrimp and also vegetables and beans. It is important to chill food and sear meats before cooking to eliminate bacteria.

What equipment do you need for sous vide cooking?
To cook sous vide, you'll need a few key pieces of equipment. The essentials are a vacuum sealer to seal food in airtight plastic pouches (heavy-duty freezer bags can be substituted) and an immersion circulator to maintain a precise, consistent water temperature. The circulator heats and moves the water to ensure even cooking, which can last from one hour to a whole day. Some circulators even come with apps to calculate the best cooking time and temperature for different foods.

Why do people use sous vide instead of traditional cooking methods?
People use sous vide cooking, a French technique where food is vacuum-sealed and cooked slowly in water at a low temperature, for several reasons. The method ensures food cooks consistently, retaining moisture and tenderness within its own juices.
Sous vide allows precise control over cooking time and temperature, leading to replicable results. This is particularly useful in professional kitchens where consistency is key. While some equipment is expensive, more affordable options are available for home cooks. Popular food choices for sous vide include steaks, ribs, and seafood, which benefit from the technique's ability to prevent overcooking and retain juiciness.

What are some foods that can be prepared using sous vide?
Sous vide is a French cooking technique where food is vacuum-sealed and cooked slowly in low-temperature water, which ensures consistent cooking and retains moisture and tenderness.
Many foods can be cooked using the sous vide method. Meat dishes like steak and ribs, which retain their juiciness, are especially popular. Seafood, such as salmon and shrimp, which can easily be overcooked using other methods, also benefit from sous vide. Cruciferous vegetables and beans are also well-suited for sous vide cooking. However, flaky fish is not recommended because it can fall apart, and boneless poultry may become rubbery.

How does sous vide affect the taste and texture of food?
Sous vide is a French cooking technique where food is vacuum-sealed and slowly cooked in low-temperature water, which helps maintain moisture and tenderness. The process ensures consistent cooking, allowing chefs to find the best temperature and time for a dish, achieving replicable results.
Meat dishes like steak and ribs retain their juiciness, while seafood like salmon and shrimp avoid overcooking. However, flaky fish may fall apart, and boneless poultry can become rubbery. Searing meat before cooking can address the grey tone that meat can take on during the low-heat immersion method and kill surface bacteria.

sous vide, French cooking technique in which food is vacuum-sealed and then slowly cooked in water heated to a low temperature. When properly done, the food cooks consistently, in its juices, maintaining moisture and tenderness.
Sous vide, meaning “under vacuum” in French, is a technique developed by French chefs in the 1970s. It was introduced to the United States by American chef Thomas Keller, a devotee of French cooking and owner of the French Laundry restaurant in California’s Napa Valley, and French chef Daniel Boulud, who was then working in New York City. In his 2008 book Under Pressure: Cooking Sous Vide, Keller praises the technique as a guarantor of consistency, a highly desired goal in any professional kitchen. With sous vide cooking, the chef or home cook can learn through experimentation the best temperature and time for any given dish, obtaining identical and replicable results.
Much of the equipment involved in cooking sous vide food in large quantity is aimed at the professional market and is expensive, although less costly equipment for home chefs is available. At the heart of the sous vide system is a vacuum sealer, with which the food to be cooked is placed inside a food-grade airtight plastic pouch and then sealed. (Home chefs may substitute a heavy-duty resealable freezer bag.) The other essential element is a circulator that attaches to the interior side of a pot and heats water to a low temperature, below simmering, then moves it constantly so that the temperature is consistent throughout the cooking process. That process may last for as little as an hour or as long as a day, depending on what is being cooked; some circulators are accompanied by computer applications that can calculate the optimal cooking time and temperature for any given food.

Many foods lend themselves to sous vide cooking. Especially popular are meat dishes such as steak and ribs, which retain their juiciness within the pouch. Seafood dishes such as salmon and shrimp, which can be easily overcooked in a pan or on a grill, do the same, as do cruciferous vegetables and beans. Chefs recommend that flaky fish not be subjected to sous vide cooking, since it can easily fall apart, while boneless poultry acquires a rubbery feel when cooked at low temperature. Meat dishes such as steak can take on a grey tone when being cooked by the low-heat immersion method, but they can be made to look more appealing by finishing them over flame.
The sous vide technique was in use in Europe for some years before it was authorized by U.S. health authorities, with scientists being concerned that food was being cooked at a low enough temperature that bacteria could flourish. This potential hazard is alleviated if the food is properly sealed, but even so, chefs recommend that before it is cooked the food in question be chilled below the danger zone (39 °F [3.8 °C]) in order to destroy any bacteria. Another safety measure is to sear meat before placing it in the pouch, killing any surface bacteria.
