Will Instant Pot release pressure while cooking?

The Instant Pot is one of the most popular multi-cookers on the market, allowing you to pressure cook, slow cook, sauté, steam, and more. When using the pressure cooking function, the Instant Pot builds up and maintains pressure to cook food quickly at high temperatures. A common question many Instant Pot users have is whether the pot will release pressure on its own while cooking.

What is an Instant Pot?

The Instant Pot is an electric pressure cooker that can speed up cooking times by using pressurized steam to cook food. Models like the Duo and Lux have multiple functions in one appliance, combining a pressure cooker, slow cooker, rice cooker, steamer, sauté pan, yogurt maker, and warmer.

Instant Pots use electric heating elements and sensors to regulate temperature and pressure. When the lid is sealed and the valve closed, the Instant Pot builds up pressure that allows water to boil at temperatures above 212°F, cooking food faster than normal boiling. Typical pressure levels are around 11-12 psi.

How does pressure cooking work?

Pressure cooking works by trapping steam inside the pot, increasing the boiling point of water and quickly cooking food with moist heat. Here’s a quick overview:

– The inner pot is filled with liquid and food is added.

– The lid is sealed and the pressure release valve closed.

– The Instant Pot heats up and generates steam, building pressure within the inner pot.

– Pressure levels typically reach around 11-12 psi, allowing water to boil at around 245°F.

– The high-pressure environment forces steam through the food at high temperatures.

– Food cooks up to 70% faster than conventional cooking.

– When cooking is done, the pressure is released manually or naturally.

This high-pressure environment steams food at hotter than normal temperatures, resulting in fast, flavorful dishes with tender and juicy results.

Will the Instant Pot release pressure on its own while cooking?

The Instant Pot is designed to maintain consistent pressure levels throughout the entire cooking time. It will not release pressure automatically or open on its own when cooking under pressure.

There are a few reasons why the Instant Pot does not release pressure during the cooking process:

Maintaining temperature and pressure is crucial

Releasing pressure mid-cycle would drastically drop the temperature inside the pot, interrupting the cooking process. To properly pressure cook food, constant heat and pressure must be held within the sealed pot.

The Instant Pot uses electric heating elements and sensors to regulate and sustain the optimal pressure level. Dropping pressure randomly would prevent food from cooking through fully and evenly.

Safety mechanisms keep the pot sealed

The Instant Pot has safety features in place to prevent the lid from opening while pressurized. This includes locking the lid in place and electronically controlling the pressure release valve.

These mechanisms ensure pressure and heat are contained in a controlled manner. Accidentally releasing pressure could be dangerous and steam could cause severe burns. Keeping the pot sealed is important for both efficient cooking and safety.

User must manually release pressure

While the Instant Pot holds pressure during cooking, the user must manually release pressure after the cook time ends. This is done using the pressure release valve.

There are two ways to release pressure:

– **Natural release (NR):** Allowing the pot to depressurize gradually over 10-20 minutes.

– **Quick release (QR):** Manually turning the pressure release valve to vent steam until the floating valve drops.

Releasing pressure is necessary to unlock the lid and access the cooked food. This step must be done by the user and won’t happen on its own.

Common scenarios when pressure is released

While the Instant Pot maintains constant pressure during the set cook time, there are a few instances when pressure may be released unexpectedly:

Safety mechanisms trigger

The Instant Pot has safety features that may automatically release excess pressure in rare cases:

– **Over pressure:** Pressure exceeds the preset limit, causing steam release through the valve.

– **Overheating:** Internal temperature gets too high, releasing pressure to avoid burns or damage.

– **Power failure:** Electricity cut off will interrupt heating, dropping pressure.

– **Float valve stuck:** If the float valve gets obstructed, pressure may leak out gradually.

In most cases, these safety releases prevent only a portion of the steam from escaping before the pot re-pressurizes.

User errors

Mistakes when using the Instant Pot can also accidentally release pressure:

– Forgetting to seal the lid and close the valve when starting cooking.

– Turning the pressure release valve the wrong way.

– Pressing the pressure release button on the lid instead of turning the steam release handle.

– Attempting to open the lid before fully depressurizing.

Following the Instant Pot instructions carefully can prevent errors that may improperly vent pressure.

Pressurization problems

In some instances, the Instant Pot may fail to properly pressurize and maintain pressure:

– **Not enough liquid:** Without adequate water/broth, pressure can’t build.

– **Food debris blocking vent:** Solid bits may block the valve from sealing.

– **Damaged sealing ring:** A worn or cracked ring prevents forming a tight seal.

– **Faulty valves/sensors:** Mechanical or electronic issues can prevent pressurization.

Troubleshooting these problems is important to get the Instant Pot to reach and hold the right pressure levels.

How to prevent accidental pressure release

While the Instant Pot is designed to maintain pressure, you can take steps to prevent accidental release:

– Carefully read manufacturer instructions

– Check that sealing ring and valves are clean and undamaged

– Use at least 1 cup liquid for pressure cooking

– Make sure venting valves are clear of debris

– Don’t overfill inner pot

– Seal lid and close pressure release valve before starting

– Don’t attempt to open lid until fully depressurized

– Release pressure properly at end of cooking

– Replace worn sealing ring annually

Following Instant Pot guidelines for use and maintenance will ensure the pot functions as designed. Taking precautions helps avoid user errors that can cause steam to vent unexpectedly.

Releasing pressure properly

When cooking is finished, it’s important to release pressure using the correct method:

Natural release

– Leave the pressure release valve in the sealed position at the end of cooking.

– Allow the pot to come down from pressure naturally over 10-20 minutes.

– The float valve will drop when fully depressurized.

– Press down on the lid and turn to open once pressure is fully released.

Quick release

– Turn the pressure release valve to the venting position.

– Steam will rapidly escape through the valve.

– Keep hands and face clear of the venting steam.

– Turn valve back to sealing position once the float valve drops.

– Press lid and turn to open when fully depressurized.

Releasing pressure improperly can be dangerous, so follow Instant Pot guidelines carefully. Make sure pressure is completely released before attempting to remove the lid.


The Instant Pot is engineered to maintain steady pressure levels throughout the entire cooking time. It will not begin releasing pressure on its own while cooking recipes under pressure.Dropping pressure mid-cycle would lead to improperly cooked food.

While accidents can happen, following the manufacturer’s instructions for use, maintenance, pressurizing, and depressurizing will ensure your Instant Pot seals and maintains pressure properly for the best results. Releasing pressure safely at the end of cooking is essential and must be done manually by the user.
