Air Fryer Vs. Pressure Cooker: Which One Is Better for YOU?

In today’s fast-paced world, where time is often a luxury, kitchen gadgets like air fryers and pressure cookers have become indispensable. They promise to reduce cooking times significantly, offer healthier meal options, and simplify the cooking process. While both appliances aim to make cooking more convenient, they do so in vastly different ways. The air fryer uses rapid air technology to crisp and brown foods without the need for excessive oil, appealing to health-conscious individuals. On the other hand, the pressure cooker uses high pressure to cook food quickly, retaining flavors and nutrients efficiently. Deciding between the two depends on various factors, including cooking preferences, dietary restrictions, and lifestyle needs.

How Does an Air Fryer Work?

An air fryer is essentially a compact, countertop convection oven that circulates hot air around food to cook it. This appliance features a heating element and a fan, generating a rapid flow of hot air together. The air circulates around the food placed in a basket, cooking it evenly and creating a crispy outer layer. This method mimics the results of deep-frying but uses significantly less oil, making it a healthier alternative. The efficiency of the air fryer lies in its ability to cook food quickly, evenly, and with minimal preheating time, making it an excellent option for busy individuals looking to prepare meals in a jiffy.

Pros and Cons of Air Fryers


  • Healthier Meals: Air fryers use less oil, offering a healthier alternative to traditional deep-frying, reducing the overall calorie and fat content of meals.
  • Convenience: Air fryers heat up quickly and cook food faster than conventional ovens. They’re also easy to use, with simple temperature and time settings.
  • Versatility: These appliances are not just for frying; they can also grill, roast, and bake, offering a wide range of cooking options.
  • Easy Cleanup: Most air fryers come with non-stick baskets and are dishwasher safe, making cleanup a breeze.


  • Limited Capacity: Air fryers are generally smaller than pressure cookers, making them less suitable for larger families or meal prep.
  • Uneven Cooking: Depending on the model and how food is arranged, air fryers can sometimes cook food unevenly, requiring occasional shaking or flipping.
  • Taste and Texture Differences: While air fryers can mimic the texture of deep-fried foods, some differences in taste and texture are inevitable due to the reduced oil usage.
  • Cost: High-quality air fryers can be expensive, making them a significant investment for some households.

How Does a Pressure Cooker Work?

A pressure cooker is a sealed pot with a lot of steam inside, building up high pressure, which helps cook food faster. When you heat the pot, the liquid inside forms steam, which raises the pressure in the pot. This high pressure has two major effects. First, it increases the boiling point of the water or liquid in the pot, which can reach up to 121°C (250°F), much higher than the normal boiling point of water. Second, the high pressure forces moisture into the food, which can make it cook faster and also helps certain foods, like tough cuts of meat, become tender more quickly than they would with traditional cooking methods.

The science behind pressure cooking is based on the principles of physics. The sealed environment of the pressure cooker increases the atmospheric pressure inside relative to the outside. Water or any liquid under pressure boils at a higher temperature because the increased pressure raises the boiling point. Consequently, the higher temperature cooks food faster.

Pros and Cons of Pressure Cooking


  1. Speed: Pressure cooking is much faster than conventional cooking methods.
  2. Energy Efficiency: It uses less energy since it cooks faster and uses a single pot.
  3. Nutritional Benefits: Cooking under pressure retains more nutrients than boiling because fewer nutrients are lost to the cooking water.
  4. Versatility: It can be used for a wide range of dishes, including soups, stews, and even desserts.
  5. Flavor: The fast cooking and sealed environment can enhance flavors and tenderize meats more effectively.


  1. Learning Curve: Getting used to the settings and how they affect cooking times can take some time.
  2. Maintenance: Seals and valves need regular checking and replacing.
  3. Initial Cost: High-quality pressure cookers can be an investment.
  4. Overcooking Risk: It’s easy to overcook items if the pressure cooker is left unattended.
  5. Safety Concerns: While modern pressure cookers are much safer, there is still a risk of explosion if they are improperly used or maintained.

Main Differences Between a Pressure Cooker and an Air Fryer

The primary difference between a pressure cooker and an air fryer lies in their cooking methods and the results they deliver. A pressure cooker uses steam pressure to cook food quickly, preserving nutrients and flavors while reducing cooking time significantly. It’s ideal for cooking tough cuts of meat, beans, stews, and soups. The sealed environment increases the boiling point of water, which speeds up the cooking process. Pressure cookers can be either stovetop models or electric.

On the other hand, an air fryer cooks by circulating hot air around the food, creating a crispy outer layer while keeping the inside moist. It mimics the results of deep-frying but with significantly less oil, making it a healthier option for those looking to reduce fat intake. Air fryers are excellent for cooking frozen foods, vegetables, and even baking small goods. They are exclusively electric and come in various sizes.

The choice between these two appliances depends on your cooking preferences. A pressure cooker might be more suitable if you prioritize speed and versatility for a wide range of dishes, including soups and stews. Conversely, an air fryer could be the better option if you’re aiming for healthier, crispy food with less oil.

Can You Use a Pressure Cooker as an Air Fryer?

While both appliances are versatile, using a pressure cooker as an air fryer is not straightforward. Traditional pressure cookers are designed for wet cooking methods and cannot replicate the air frying process’s dry, circulating heat. However, some modern electric pressure cookers come with built-in air frying capabilities or as an additional attachment.

These multi-cookers can switch between pressure cooking and air frying, offering the best of both worlds. If you own a traditional pressure cooker, though, you’ll need a separate air fryer to achieve the crispy texture that air frying provides.

Frequently Asked Questions

Is pressure cooking healthy?

  • Yes, pressure cooking is healthy. It retains more nutrients compared to boiling and even steaming because of the reduced cooking time and less liquid required.
