6 Differences Between Pressure Cooker and Slow Cooker

6 Differences Between Pressure Cooker and Slow Cooker

Perhaps you have a pressure cooker and a slow cooker in your home. It is simple to point out visible differences that distinguish the two cooking appliances. A physical examination reveals surface differences between the two cooking appliances. But a physical examination is not sufficient to comprehensively highlight the differences between pressure cookers and slow cookers. Their functions are almost intertwined. For example, both can cooked varied foods. Below is a list of essential determinants that differentiate pressure cookers and slow cookers.

Mode of Functioning​

Slow cookers slowly cook food under low temperatures using steam. Steam together with gentle heating boost the cooking functions of slow cookers. Food cooked with the best slow cooker has enough time to simmer as it is cooked almost the whole day.

Pressure cookers cook food under a high pressure atmosphere by using highly heated steam. A lid is used to tightly seal the pressure cooker leading to sufficient pressure accumulation. The pressure is responsible for properly cooked food.

Cooking Time​

Slow cookers consume many hours in cooking food because they use very low levels of energy. The process takes a minimum of 6 hours. Food has to be prepared in advance so that it is ready by dinnertime.

The best pressure cookers cook food very fast due to the high levels of pressure. They are suitable cooking devices when food needs to be prepared quickly. Prior food preparation is unwarranted because food does not take long to cook.

Energy Consumption​

Slow cookers take long hours to cook food under low temperature conditions. Hence use very little energy.

Pressure cookers dependent on high pressure to cook food. For high pressure levels to be reached, a lot of energy is needed.


Slow cookers are largely easy to maintain. They have lesser features than pressure cookers which guarantees convenient cleaning.

Cleaning pressure cookers has to be done in a careful way. Pressure cookers have many features-pressure regulators, a locking lid, and a pot- which need to be handled with great care to avoid damage.

Monitoring Capability​

Slow cookers provide ease of monitoring food. Lids can be detached to monitor cooking progress from time to time. Extra ingredients can be added while monitoring the food.

In pressure cooking, it is difficult to monitor cooking progress. The lid cannot be detached until cooking has stopped. Adding extra ingredient forces a person to first stop the cooking process and wait for pressure to be released.

Varieties of Food Cooked​

Pressure cookers can cook more varieties of food than a slow cooker. Other than soup, stew, meat and vegetables which are common in both types of cookers, a pressure cooker can cook other foods such as rice and grains which a slow cooker cannot.​

As explained above, there are key differences that make pressure cookers and slow cookers stand out. This does not mean that either cooking device is superior to the other. The cooking device favored is dictated by the personal preferences and tastes of users. Users have the freedom to select any of the cooking device depending on what they want to cook, how much time they want to spend and the preferred cooking method.
