If you're looking for a new kitchen appliance to simplify cooking, you might be considering an Instant Pot (pressure cooker) or an air fryer. Both appliances can cook a whole meal in less than an hour and are healthier alternatives to more traditional cooking methods. However, they have many differences, and it can be tricky to decide which one is best for your needs.
| Characteristics | Values |
|---|---|
| Safety | Pressure cookers have safety measures to prevent burns, but scalding steam can be released when opening the pot. Air fryers can get hot to the touch and increase the likelihood of burns. |
| Cooking method | Pressure cookers use steam to cook food faster. Air fryers use hot air circulation to cook food. |
| Liquid required | Pressure cookers require at least a cup of water or broth. Air fryers use a small amount of oil. |
| Food produced | Pressure cookers produce softer foods. Air fryers produce crispy foods. |
| Time | Pressure cookers can reduce cooking time by up to two-thirds. Air fryers preheat in under five minutes. |
| Versatility | Pressure cookers can perform multiple functions, such as slow cooking, rice cooking, and yogurt-making. Air fryers have a single function but can be used for various tasks, including baking and toasting. |
| Price | Pressure cookers are generally more expensive than air fryers. |
| Checking food during cooking | Pressure cookers require releasing steam before opening the lid. Air fryers allow you to check food at any time. |

How they work
Air fryers and pressure cookers are both versatile appliances that can cook a whole meal in under an hour. They are also healthier alternatives to traditional cooking methods like deep frying. However, they are very different in how they cook food.
An air fryer is a small convection oven that uses hot air to cook food. It works by circulating hot air around the food at high speeds. The heating element is at the top of the cooking chamber, and hot air blows around the food constantly. A fan circulates the hot air for even cooking, which results in the Maillard effect, browning the food. This mimics deep frying as the food is surrounded by heat at all times, but it uses up to 80% less oil than traditional deep fryers.
A pressure cooker works by raising the internal pressure of the pot to speed up cooking times. This is done by using water or broth and sealing it in an airtight pot. As the liquid is heated, it boils and converts to steam. Because the steam can't escape, the pressure within the pot builds. The trapped pressure reduces the cooking time because the water reaches its boiling point quicker and at a higher temperature. The heated steam is forced deeper into the food, cooking it faster. After cooking, the pressure is released so that the pot can be opened safely.

Safety considerations
While both pressure cookers and air fryers are generally safe to use, there are some safety considerations to keep in mind for each appliance.
Pressure Cookers
Modern pressure cookers have multiple safety mechanisms in place to prevent accidents. These include spring-loaded valves that respond to internal pressure variations and release steam only when a specific safety threshold is exceeded. Additionally, most pressure cookers have a safety release in the form of a small hole in the rim of the lid. If the pressure becomes too high, the gasket pops out of this hole, releasing steam and preventing an explosion.
To ensure safe use of a pressure cooker, it is important to follow the safety advice in the manual and regularly inspect the cooker to ensure all seals are clean and in good repair. It is also crucial to be mindful of the maximum fill line, especially when cooking foods that expand, such as dried beans.
Air Fryers
When using an air fryer, it is important to follow basic food safety practices, such as washing hands and sanitizing surfaces before and after food preparation. To prevent cross-contamination, it is crucial to keep raw meats, poultry, and seafood separate from cooked foods and to use separate cutting boards for raw meat and produce.
Additionally, it is important not to overfill the air frying basket, as this can lead to uneven cooking and undercooking. Always follow the manufacturer's cooking instructions and ensure that food reaches a safe minimum internal temperature by using a food thermometer. For example, whole cuts of beef, pork, veal, and lamb are considered safe at 145 degrees Fahrenheit with a 3-minute rest time.
It is also worth noting that air fryers may start to smoke when cooking fatty foods like bacon or burgers. To prevent this, you can add a thin layer of water to the drawer beneath the basket.

Cost and value
Pressure cookers, also known as Instant Pots, are multi-use appliances that can replace several kitchen appliances, making them ideal for small kitchens. They can perform a variety of functions, including pressure cooking, slow cooking, rice cooking, sautéing, steaming, boiling eggs, and making yogurt. On the other hand, air fryers have fewer functions and are primarily used for convection cooking or frying. They are a healthier alternative to deep frying, as they require little to no oil, but they may not be as versatile for those looking to cook a wide range of dishes.
When it comes to convenience, air fryers have a shorter preheat time, usually under five minutes, while pressure cookers can take up to 20 minutes to build pressure. Additionally, air fryers allow you to check on the food during cooking without interrupting the process, whereas pressure cookers require you to release the steam and rebuild pressure if you want to inspect your food. This can add time to the cooking process.
It's worth noting that the cost and value of each appliance depend on your specific needs and preferences. If you're looking for a versatile appliance that can cook a variety of dishes, a pressure cooker might be a better investment. On the other hand, if you're primarily interested in frying or crisping foods with minimal oil, an air fryer could be a good choice. Ultimately, the decision should be based on your cooking requirements and the level of convenience you desire.

What foods they are best for
Air fryers are great for cooking crispy foods such as French fries, sweet potato fries, chicken, and other "beige foods". They can also be used for baking and toasting, and some models come with accessories like pizza pans, grilling trays, and cake barrels. If you're looking to cook foods that are traditionally deep-fried, an air fryer is a healthier alternative as it uses little-to-no oil.
Pressure cookers, on the other hand, are ideal for cooking meals that require a liquid element, such as stews, soups, and curries. They are also great for cooking rice, yogurt, and even boiling eggs. Pressure cookers are best for foods that need long, slow cooking, such as pulled pork. They are also a good option for one-pot meals and batch cooking, as they can cook a large amount of food quickly and efficiently.
Both appliances have their advantages when it comes to cooking specific types of food, so it really depends on your personal preferences and the types of dishes you typically prepare. If you want to cook crispy foods with minimal oil, an air fryer is a good choice. If you prefer to cook meals with a liquid base or want to prepare large quantities of food at once, a pressure cooker might be a better option.
