Air Fryer Vs Pressure Cooker (What’s The Difference?)

During the past decade, several new kitchen appliances have been introduced to the market, but some have generated more buzz than others, such as the air fryer, which provides a healthier method of consuming fried food.

Our aim today is to compare and contrast the air fryer and pressure cooker in order to determine their dissimilarities and ascertain which one would be most advantageous for you.

While the pressure cooker has been a popular appliance for a long time, the air fryer only gained public attention in recent years.

The primary contrast between the air fryer and the pressure cooker is that the latter depends on creating internal pressure to elevate the boiling point, whereas the former functions like a convection oven by circulating hot air. While the air fryer produces crispy and slightly dehydrated food, the pressure cooker yields juicy and tender dishes. Both appliances are relatively fast, but the pressure cooker is renowned for reducing cooking durations.

It is crucial to comprehend that air fryers and pressure cookers have distinct functions, so they cannot replace each other. Nevertheless, they can be excellent complements to one another.

After conducting online and offline research, I have gathered information about the Air Fryer and Pressure Cooker, and identified the specific scenarios where one may be more advantageous than the other.

If you are considering buying either an air fryer or a pressure cooker, or even replacing one with the other, this guide will provide you with useful information and advice.

What’s The Difference Between An Air Fryer And A Pressure Cooker

In order to comprehend the dissimilarities between air fryers and pressure cookers, it is necessary to examine their individual functioning mechanisms and the advantages associated with each of them.

How Does A Pressure Cooker Work

Pressure cookers are composed of two parts, a container and a lid, which when joined together create an airtight seal, making isolation a crucial aspect of their operation.

Here’s why.

When using a pressure cooker, it is essential to begin with a liquid base, such as water or broth, which will boil and create steam that remains trapped inside the sealed container, leading to an increase in pressure.

Due to the elevated pressure within the airtight vessel, the temperature increases, resulting in a significantly quicker cooking time compared to boiling water on a stove top.

The pressure cooker accelerates the boiling point of any liquid inside due to its sealed container, unlike a ventilated container where steam can escape.

The pressure cooker utilizes internal pressure to force the heated steam deeper into the food, resulting in faster cooking due to lower boiling points.

Unlike the air fryer, the pressure cooker cannot be opened midway to inspect the food as it would release the pressure, making it ineffective.

After the pressure cooker completes its cooking process, it is necessary to release the pressure inside before opening the lid, which can be achieved by using a small valve that opens up an output hole.

The pressure cooker has an output hole that safely releases steam and pressure from the container. It is important to avoid opening the lid immediately as it could be hazardous due to the possibility of the pressure inside causing the lid to blow off, which can be dangerous when combined with hot liquids.

Nowadays, electric pressure cookers are the most convenient and practical option as they have built-in heating solutions, digital displays, and timers. Although having their own heating source may seem insignificant, it is undoubtedly an improvement over manual pressure cookers.

Pressure cookers that are manually operated necessitate the user to heat the container using a stovetop or microwave oven, and if there is a need to adjust the temperature or pressure, the pressure cooker must be taken off from the heat source.

Using a pressure cooker involves placing all the ingredients in the container, powering on the appliance, and allowing it to work its magic, making it an uncomplicated cooking technique.

The Benefits Of Pressure Cookers

  • One session with a pressure cooker can handle larger quantities of food
  • Minimal effort and supervision are needed for the electric pressure cooker
  • Both Air Fryers and Pressure Cookers can rapidly achieve high temperatures.
  • Using a pressure cooker can cut down cooking times by over 50% compared to traditional methods.
  • It is possible to cook various dishes at the same time
  • Pressure cookers come in various sizes, including both large and small options.
  • Using pressure cookers is easy
  • Pressure cookers retain nutrients and eliminate bacteria.

How Does An Air Fryer Work

Air fryers use a fan and heating element to circulate heated air at high speed through the chamber, cooking food whenever it comes into contact with the circulating streams of hot air due to the convection mechanism.

By utilizing rapid air technology, the air fryer can achieve a crispy exterior and retain the moisture of the interior if cooking times are adjusted accordingly. Despite producing comparable flavor and texture to deep frying, this appliance consumes up to 80% less oil.

Are Air Fryers Worth It for Vegans?

Using less oil can reduce the number of calories consumed, which can be beneficial for those looking to lose weight or adopt a healthier lifestyle.

The reason behind the brown surface and taste of food cooked in an air fryer is due to the occurrence of a chemical reaction called the Maillard reaction, which happens between amino acids and carbohydrates during the cooking process.

Due to their smaller size, air fryers require less time to reach the necessary temperatures, which makes them a popular option in today’s fast-paced world.

Air fryers typically come with customizable timers and temperature settings, making the cooking process effortless. All you need to do is put your food in the basket, adjust the time and temperature according to your preference, or use the pre-set options.

With the exception of shaking, stirring, or flipping the food halfway through, the air fryer essentially automates the cooking process.

The Benefits Of Air Fryers

  • Reduced cooking times
  • It is possible to imitate the flavor, consistency, and look of fried food without utilizing oil.
  • An adaptable gadget that has the capability to bake, grill, roast, toast, fry, dehydrate, reheat and perform various other functions.
  • Compared to a traditional oven, the air fryer’s compact size makes it ideal for cramped spaces such as dorm rooms, campers, and small areas.
  • For as low as $50, you can purchase an air fryer, while pricier models usually offer additional features, cooking area, and accessories.
  • Decreases the number of calories in fried food by as much as 80%.

Key Differences Between Air Fryers And Pressure Cookers

  • While air fryers use dry heat to produce a crispy exterior, pressure cookers utilize moist heat to maintain the juiciness and tenderness of the food.
  • When cooking with an air fryer, it is possible to open the appliance to check on, stir or flip the food without any adverse effects. However, opening a pressure cooker while in use can result in the release of pressure.
  • Compared to pressure cookers, air fryers are easier to move around due to their compact size and lightweight design.
  • Compared to pressure cookers, air fryers are generally more compact in size, making them simpler to tidy up.
  • While pressure cookers are capable of preparing soups, air fryers are not suitable for liquid-based dishes.
  • When it comes to cooking methods, air fryers are ideal for foods that are typically deep-fried, pan-fried, oven-baked, or grilled, while pressure cookers are suitable for steaming, boiling, and stovetop cooking.

Can You Air Fry In A Pressure Cooker

Regrettably, it is not possible to air fry using a pressure cooker since the cooking methods of the pressure cooker and air fryer are distinct. The air fryer employs dry heat circulation that creates a crunchy exterior while retaining the moist interior of the food. The crispy texture and appearance of air fried dishes are due to “The Maillard Reaction.”

When using a pressure cooker, the cooking process involves boiling water that produces moist hot steam, which prevents the Maillard reaction from occurring. As a result, the air fryer cannot be replicated by a pressure cooker.

Is An Air Fryer Better Than A Pressure Cooker

Whether the air fryer or pressure cooker is superior depends on your specific needs and usage. While the pressure cooker may excel in certain aspects, the air fryer may outperform it in others. To determine which appliance would be most advantageous for you, a comparison between the two is necessary.

Size & Capacity

Various sizes are available for both the air fryer and pressure cooker. The 1-2 quart air fryers, which have a cooking capacity of 0.94L, can only accommodate 1-2 chicken breasts or enough french fries to satisfy a maximum of two individuals.

Nevertheless, air fryers of considerable size can prepare sufficient food for a large group or family. Air fryers with a capacity of 5.3 quarts or more are spacious enough to cook an entire chicken, and the most extensive air fryer on the market is the colossal 16-quart Big Boss.

Pressure cookers are available in various sizes, starting from 1-quart models to as large as 35-40 quarts, with a range of options in between.

Final thoughts: When it comes to size, pressure cookers are typically larger than air fryers, making them a better option for restaurants. However, both appliances offer ample choices for home users.
