Rice Cooker vs. Pressure Cooker (9 Main Differences)

Rice cookers and pressure cookers are essential kitchen appliances that simplify cooking.

Although they have a lot of similarities, they are very distinct.

Here are the differences between rice cookers and pressure cookers.

1. Method of Cooking

One of the most significant differences between a rice cooker and a pressure cooker is the method of cooking.

A rice cooker is a self-contained unit with a cooking pot placed inside a casing.

There is an electric heating element at the base of the pot, which heats water. The boiling water cooks the rice.

Once the rice is cooked, the sensor shuts down the appliance or switches to the “Keep Warm” mode.

A pressure cooker, however, uses pressure cooking to prepare the food. You can use it to prepare a variety of dishes apart from rice.

The pressure cooker has a lid with a rubber gasket that traps steam.

It works by creating a high-pressure environment that cooks food faster than other cooking methods.

Pressure cookers may also have multiple settings to adjust the pressure level and time of cooking to produce varying results.

2. Cooking Time

Rice cookers and pressure cookers use different cooking methods to cook food. This affects the time required for cooking.

Rice cookers typically take longer than pressure cookers to prepare food. Cooking time varies widely with the model, rice variety and program.

However, pressure cooking is a faster and more efficient way of cooking food.

A recipe may specify only a few minutes at pressure, but total time also includes heating up and safely releasing pressure.

In a rice cooker, there is more evaporation of liquid. However, pressure cooking doesn’t involve as much evaporation.

So you will have to pay more attention to the water levels to prevent overcooking the food.

3. Pressure Levels During Cooking

The rice cooker is a simpler kitchen appliance compared to a pressure cooker. It has limited functionalities and hence only a few settings.

It cooks rice automatically, but you can’t customize much of the process.

Depending on the model, it may have different settings for brown rice, white rice, etc.

Ordinary non-pressure rice cookers cook at atmospheric pressure. Some specialized rice cookers also use pressure, so check which type you own.

A pressure cooker, however, allows you more flexibility and customization choices.

It has a range of pressure and time-setting options to choose from.

Depending on the recipes and the ingredients, you can vary the pressure cooker settings to cook it perfectly.

So you can choose a different setting for rice and another one for vegetables or meat.

4. Versatility

Rice cookers are primarily built for cooking rice. Though they have a few other functionalities, it’s highly limited.

You can cook a few other food grains or other ingredients using the available settings on the rice cooker.

Pressure cookers are more versatile.

You can use them to cook a variety of ingredients including rice, vegetables, beans, meat, and even desserts or pasta.

Since there are more settings for a pressure cooker, you have more cooking options.

5. Checking on The Food Mid-Way

Follow the supervision and lid-opening instructions for the exact model.

Some non-pressure rice cookers permit opening during certain programs. Others do not; pressure rice cookers must remain locked until their approved release process is complete.

This gives you the flexibility to add seasonings or flavoring agents during the cooking process.

But this is not possible for a pressure cooker.

Pressure cookers work by locking the ingredients in a pressure chamber.

So you can’t open the lid without first releasing the built-up pressure.

But doing so will bring the pressure level down and stop the cooking process. So it will have to start building up the pressure yet again to get going.

6. Rice Cookers Allow More Room for Error

The cooking process in a rice cooker is gradual, allowing you more room to correct potential problems.

Make mid-cycle adjustments only if the manual and recipe allow them. Opening a lid can release steam and affect the result.

However, pressure cookers should be handled with more caution. They cook food very quickly and under high pressure.

A pressure cycle can be stopped using the controls, but the lid must remain closed until pressure has been released safely.

There are chances of overcooking the ingredients if you wait for too long or get the measurements wrong.

7. Follow Each Cooker’s Supervision Instructions

Automatic cooking controls do not mean that every cooker can safely be left unattended.

Read the supervision instructions for your exact model and the dish you are preparing.

Rice cookers will automatically shut down or switch to the “keep warm” mode once cooking is over.

Do not use an automatic Keep Warm switch as a reason to leave the house while cooking. For example, Aroma’s ARC-302NG instructions say not to leave it unattended.

Meanwhile, pressure cooker manufacturers advise against leaving the house when the device is on.

You should stick around while the food cooks to check for unintended steam release due to excessive pressure build-up.

8. Capacity and Price

Both rice cookers and pressure cookers are available in a range of sizes and with varying capacities.

However, rice cookers are typically smaller in size than pressure cookers. They also have a smaller control panel due to the limited cooking options available.

With a few exceptions, pressure cookers are generally bulkier than rice cookers. They are large and can hold more ingredients.

Neither category is always more expensive: basic stovetop pressure cookers and premium pressure rice cookers can reverse that comparison.

However, this can also depend on the brand and model.

9. Cleaning and Maintenance

Rice cookers are generally easier to clean and maintain. They have only a few parts that can easily be taken apart.

In some cases, the cooking vessel will also be dishwasher friendly. However, check the manufacturer’s instructions to confirm.

Pressure cookers are generally more difficult to clean and maintain. They have several small parts.

The lid and rubber gasket require special attention during cleaning. Pressure cooker parts may or may not be dishwasher-friendly depending on the brand.

Nonetheless, you will have to exercise more care for properly cleaning them.

The following table summarizes the differences between the two appliances.
