Sous Vide Vs. Slow Cooker: Everything You Need To Know

You can make your cooking process easy and deliver great-tasting food by implementing some new cooking methods. Let’s delve into the ‘sous vide’ vs. slow cooker debate.

Sous vide and slow cookers are lovely cooking methods, especially if you’re busy and can’t spend too much time in the kitchen. Sous vide or slow cookers can be a great addition to your kitchen appliances and make your cooking experiences simple and precise.

But we would like to know the differences between these two great cooking appliances. Are there any significant differences between slow cookers and sous vide, and what are their similarities?

This insightful article will look at everything you need to know about sous vide and slow cooker, and we will also recommend some of our best picks for these two cookers. So, let’s discuss sous vide vs. slow cookers and get to know which wins the battle.

Sous Vide: Overview

When we talk about the sous vide cooking technique, it is a process that involves utilizing precise temperature control, and this helps deliver consistent restaurant-quality results.

You can use this unique cooking appliance (water oven) as a sous vide, or you can get a device that will be placed into a water container (immersion circulator).

With an immersion circulator, water is heated to a particular temperature and simultaneously circulates heat. Then the food to be cooked is placed in a tight sealable plastic bag inside the water bath. So, this way, the food will be cooked gently and evenly for an extended period in the sous vide circulator.

Then with the help of the video cookers, you get an exact or desired temperature setting. This means the water bath never exceeds the temperature setting, making it impossible for your food to be overcooked.

The sealed bag where the food is placed allows the moisture to be retained in the food tissues. Therefore, your food will be cooked without losing flavor, nutrients, or aroma.

Top-notch restaurants have used this cooking technique for years to prepare food to a precise level of doneness. This cooking process has become popular and available in our homes, thanks to an easy-to-use kitchen tool.

Slow Cooker: Overview

The name ‘slow cooker’ means they do precisely what their name tells. This slow cooker (also referred to as a crockpot) is a countertop cooking tool that simmers your food, and it is similar to a stovetop pot. This cooking appliance is usually made of stainless steel, porcelain, or ceramic surrounded by an electric heating element.

This design of this instant cooking pot doesn’t allow for evaporation, so food is in an enclosed environment. Now, this enclosed surrounding is sealed with a lid, and constant low temperature enables the food inside to heat rapidly. So, the food remains hot for a long cooking time.

The heat retention of this slow cooker is pretty compelling, making it ideal to be used on tougher cuts of meat that requires moist slow cooking in a low heat environment to tenderize.

Additionally, this cooking equipment is a good idea for making stew, soups, and sauces, which need to simmer for some time.

Sous Vide vs. Slow Cooker: Similarities

Before we look into sous vide vs. slow cooker, let’s quickly dive into their similarities.

Long Cooking Time

Both sous vide, and slow cooking methods utilize recipes that call for a cooking time of 6 or more hours. So, if you’re the busy one that can’t spend a lot of time in the kitchen, you can simply start cooking your food in the morning and have it ready for dinner.

Tenderizes Tough Cuts of Meat

You can use both sous vide and slow cooking techniques to tenderize tougher cuts of meat, thanks to the long period of lower temperature both cooking methods utilize.

Collagen is present in the meat tissue that gets softened into gelatin, and moisture and juiciness are added to the food. So, the meat is heated and gets soft, making the cut of meat tender and flavorful.

Heat & Energy Efficiency

Both slow cooker and sous vide won’t take much energy compared to a stovetop. Also, your food is cooked without heating up your kitchen space.

Sous Vide vs. Slow Cooker: Differences

The significant differences between sous vide vs. slow cooker have been stated below.

Temperature Accuracy & Precision 

Usually, slow cookers have only ‘high, low, warm’ temperature settings, and there isn’t a precise temperature setting.

Sous vide immersion calculator, on the other hand, is a thermostat and can help set the temperature to a precise setting and accuracy. This allows water circulation within 1 to 2 degrees of the desired temperature. Therefore, the precision of sous vide cookers enables us to cook our food to our preference.

Nutrient Loss

When it comes to nutrient loss in food, a slow cooker does not preserve food nutrients (in vegetables, for example), and this is because of the process of slowly cooking food for an extended time. So, minerals, vitamins, and micronutrients in vegetables are lost.

As the cooking process prolongs in the slow cooker, the internal enzymes degrade trace nutrients in the vegetables, making vegetables less nutritious.

On the other hand, the Sous vide method is an excellent cooking technique that retains nutrients even in vegetables. This is thanks to the food being cooked within resealable bags. So, the food won’t be exposed to excessive heat or immersed in water.

Furthermore, the sous vide container cooker allows you to cook your food enough to pasteurize it, eliminating bacteria without overcooking your food. Also, the texture, flavor, color, and nutrients of your food are always retained when you’re cooking with sous vide.

Overcooking Risk

Slow cookers have a lid that allows heat retention, and evaporation is minimal. However, it is still possible to overcook your food in a slow cooker, and if you leave the food for a long time, it can burn or dry out.

But when it comes to sous vide cookers, the desired temperature is never exceeded. Therefore, your food can’t be overcooked (unless you pick the wrong temperature).

When you leave your food in a sous vide unattended for a long time, the water can evaporate and stop heating the food. However, your food can’t burn, dry out, or get overdone.

Main Differences: Overview

Apart from the differences we’ve listed above, the most significant difference in sous vide vs. slow cooker should be the resulting meal you get at the end of the day.

  • Slow cookers are famous for their one-pot meals, which allow you to have your food hot and ready to eat. They are perfect for stews, chili, roasts, and other dishes that combine seasonings and ingredients and simmer them all together for a long time.
  • Then sous vide water bath will give you that perfectly cooked meat or fish, vegetables, eggs, and so on. These food are sealed in their individual vacuum bags, and then after cooking, they can be arranged into a meal.
