Common Pressure Cooker Mistakes

(Updated: Feb. 20, 2026, 8:56 a.m.)

Today’s electric pressure cookers like the Instant Pot have made cooking weeknight dinners faster and more convenient than ever. For some beginners, this kitchen tool can feel confusing or even intimidating. 

Pressure cooking depends on a combination of precise levels of liquid, a sealed environment, and controlled steam release. Whether it’s burnt food or undercooked beans, most pressure cooking problems actually come down to simple mistakes that can be easily fixed. 

Understanding these errors can help you build confidence and create quick, healthy weeknight meals. Below are a few of the most common pressure cooker mistakes and how they can be avoided.

Mistake 1: Not Adding Enough Liquid


Requires ½ cup to 1 cup depending on the size of your pressure cooker. Always refer to the manufacturer’s directions. If you do not have enough liquid, there won’t be enough steam for even cooking. Not adding enough liquid can also lead to the cooker either burning your food or the cooker itself turning off before cooking is complete. 

Mistake 2: Forgetting to Close the Pressure Valve


Electric pressure cookers have a pressure valve that must be turned in order to seal or release pressure. If you start your pressure cooker and notice that it’s taking a very long time to reach the required pressure, check to make sure the pressure valve is closed or turned to “seal.” 

Mistake 3: Confusion of Pressure Release Methods


A common mistake is not using the correct pressure release method once the cook time is complete. Electric pressure cookers come with two options for releasing steam - quick release and natural release. Both are very different and lead to different results. For example, using natural release for a delicate dish like vegetables could cause them to be overcooked and mushy.

Quick Release vs Natural Release Methods:


Quick Releaserequires you to turn the pressure valve to quickly release the steam and lower the pressure rapidly. It usually takes 5 minutes or less.

Recipes for quick release include vegetables, eggs, and fish. 


Natural Releasemeans that you will let the pressure release on its own. This allows the cooker to release pressure more slowly. It can take as little as 10 minutes to 25 minutes or longer depending on what you are cooking.

Recipes best for natural release include meats, beans, rice, stews, and soups. 


Mistake 4: Pressure Canning in a Pressure Cooker


It is not recommended to pressure can inside of a pressure cooker. Pressure canning recipes require a specific amount of pressure for a specific amount of time in order to destroy pathogens and spores that can withstand very high temperatures. Even though some pressure cookers may be able to reach up to 15 pounds of pressure, it may not be maintained for the appropriate amount of time required to destroy these pathogens for a safe product.
