What is Sous Vide?

Sous vide literally means “under vacuum” in French. When you cook something sous vide, food is placed in a vacuum-sealed bag in a water bath at precise temperatures, often well below the boiling point. Restaurant chefs have used this cooking method for years because it offers exact control of the finished product and leaves very little room for human error. For example, if you cook a steak in a water bath set at 140ºF, there is no way the steak can get hotter than 140ºF and so you end up with a perfectly cooked medium steak, whether you cook that steak for one hour or four hours.

Why Sous Vide at Home?

In addition to delivering perfect results with very little effort, there are other advantages to sous vide cooking. The texture of food is enhanced when cooked gently in a water bath, rather than quickly on a stovetop. Cooking a pork shoulder for 24 hours in a sous vide water bath will give you pork that will just fall apart when shredded, but it won’t be dry or over-cooked. Similarly, a brisket cooked sous vide can be super tender, but still have a little pink left to the meat. It will be tender without being cooked well done.

In addition, sous vide foods cook in a bag alone, in their own juices or with other ingredients that you put in the bag. There is no loss of moisture or flavor and in fact, foods can be infused with the flavors of other ingredients. Cooking halibut in a bag with butter and orange juice results in tender, moist and delicious fish infused with orange flavor.

Sous vide machines keep the water at a very precise low temperature. These machines used to be quite large and were therefore primarily used by restaurants rather than home cooks. These days, however, there are many brands of sous vide circulators that can be purchased at very reasonable prices, making sous vide practical for home use.

If you are thinking that sous vide cooking is complicated and really only suited to professional chefs, I implore you to think again. Sous vide cooking at home is relatively new, but it falls into the same category as slow cookers, pressure cookers and air fryers – it’s another great appliance that can help home cooks get a successful dinner on the table with very little effort.

Equipment Needed

In order to cook sous vide, you will first and foremost need a sous vide circulator. This is the tool that will heat and circulate the water. It’s usually not much bigger than an immersion blender and can be used in any vessel.

A large vessel is the next piece of equipment that you will need. I like to use a stockpot or container that is at least 8 quarts in capacity so there is plenty of room for both the circulator and the food I’m cooking. Whatever you use just needs to be food safe and able to hold water. How big a vessel you can use is limited by the brand of circulator you buy. Check to see what maximum amount of water your circulator can efficiently heat and then you’ll know what size vessel to get. You can find a number of large restaurant style storage containers available for single purchase online.

You’ll also need some zipper-lock bags. I recommend freezer bags with a double zip seal. It is very important that no water enters the bag, so good-quality food safe bags are a must.

A vacuum sealer is certainly nice to have to remove the air from the bags, but it’s not critical. You can remove air from the bags in a number of ways, as you will see in the bag sealing techniques section.

Time and Temperature

Knowing how long to cook foods and at what temperature is a puzzle to anyone new to sous vide cooking. I recommend starting with recipes until you get the hang of the technique. Then, at the back of this book, you’ll find extensive cooking charts with both time and temperature listed for different foods, from meats to vegetables to desserts and dairy products.

Seasoning

Seasoning your foods with salt is very important, but you have the option of seasoning before you cook sous vide or afterwards, once the food comes out of the bag. Salt does affect foods in more ways than just bringing out flavors. It draws out moisture and therefore changes the textures of foods, making it firmer. Sometimes you want that texture change (as with fish) and sometimes you don’t (as in flank steak).

I generally use time as the determining factor for when I season foods. If the food is cooking sous vide for a shorter period of time (under 2 hours), I’ll season before I put the food in the bag. If it is cooking for a longer period of time, I’ll season after the food comes out of the bag.

Finishing

While cooking sous vide will give you perfectly and evenly cooked foods that are tender and moist, it won’t brown at all and can’t create a crust on the exterior of foods. So, to remedy that shortcoming, it’s common to sear foods either before or at the end of sous vide cooking.

Searing food before you put it in the bag will give you some color, but the texture that searing provides will be lost after the food has cooked in its own juices for a little while. The advantage to searing ahead of time is that it can help adhere a seasoning to the food, and it gives you a head start so that if you choose to sear the food at the end of cooking, you already have some color to start with.

Searing at the end of sous vide cooking needs to be done quickly and in a very hot pan so that you don’t lose the benefits of what you’ve just done – you don’t want to over-cook your food at this point. Heat a skillet over high heat for at least a couple of minutes. Add a little oil and try to sear for no longer than a minute per side. You can also use a very hot grill to sear food at the last minute.
