Pressure cookers have revolutionized the way we cook, allowing us to prepare a wide range of dishes quickly and efficiently. One of the key features of pressure cookers is the natural release mechanism, which plays a crucial role in ensuring the safety and quality of the cooked food. In this article, we will delve into the world of natural release pressure cookers, exploring how they work, their benefits, and how to use them effectively.
What is Natural Release in Pressure Cookers?
Natural release, also known as NR, is a process that occurs when the pressure cooker is allowed to release its pressure naturally, without the use of a quick release valve. This process involves the gradual decrease of pressure inside the cooker, allowing the food to cool down slowly and safely. Natural release is an essential step in pressure cooking, as it helps to prevent the food from becoming overcooked or mushy.
How Does Natural Release Work?
When you cook food in a pressure cooker, the pressure inside the cooker increases rapidly, causing the food to cook quickly. However, when the cooking time is up, the pressure cooker needs to be depressurized to allow the food to be safely removed. This is where natural release comes in. The natural release process involves the following steps:
- The pressure cooker is turned off, and the heat source is removed.
- The pressure cooker is allowed to sit for a period of time, usually between 10-30 minutes, depending on the type of food being cooked.
- During this time, the pressure inside the cooker gradually decreases, allowing the food to cool down slowly.
- As the pressure decreases, the lid of the pressure cooker begins to loosen, indicating that the natural release process is complete.

What is Natural Release in Pressure Cookers?
Natural release in pressure cookers refers to the process of allowing the pressure inside the cooker to decrease naturally after cooking, without using the quick-release valve. This method is also known as “passive release” or “slow release.” It’s an essential technique to master when using a pressure cooker, as it helps prevent overcooking and ensures that the food is cooked evenly.
When you use the natural release method, the pressure inside the cooker decreases gradually, allowing the food to cool down slowly. This helps to prevent the formation of foam and splashing, which can occur when the quick-release valve is used. Natural release is particularly useful when cooking delicate foods, such as fish or eggs, as it helps to prevent overcooking and retain their texture.
How Does Natural Release Work in Pressure Cookers?
Natural release works by allowing the pressure inside the cooker to decrease naturally through a process called “heat dissipation.” When the cooking time is up, the heat source is turned off, and the cooker is allowed to cool down. As the cooker cools, the pressure inside decreases, and the valve opens, releasing the steam slowly. This process can take anywhere from 10 to 30 minutes, depending on the type of cooker and the amount of food being cooked.
During the natural release process, the cooker’s valve will start to release steam slowly, and you may hear a gentle hissing sound. This is a sign that the pressure is decreasing, and the cooker is releasing the steam naturally. It’s essential to wait until the valve has stopped releasing steam and the pressure has dropped to zero before opening the cooker.
What are the Benefits of Using Natural Release in Pressure Cookers?
Using natural release in pressure cookers has several benefits. One of the main advantages is that it helps to prevent overcooking, which can occur when the quick-release valve is used. Natural release also helps to retain the texture and flavor of the food, particularly when cooking delicate foods. Additionally, natural release is a safer method, as it prevents the formation of foam and splashing, which can occur when the quick-release valve is used.
Another benefit of natural release is that it helps to reduce the noise level when cooking with a pressure cooker. When the quick-release valve is used, it can create a loud noise, which can be disturbing. Natural release, on the other hand, is a quiet and peaceful process, making it ideal for cooking in a home environment.
How Long Does Natural Release Take in Pressure Cookers?
The time it takes for natural release to occur in pressure cookers can vary depending on the type of cooker and the amount of food being cooked. Generally, natural release can take anywhere from 10 to 30 minutes. However, some cookers may take longer, especially if they are larger or have a more complex valve system.
