Air fryers are a quick, efficient, and accessible way to achieve the perfect roast without the need for specialised equipment. In this article, we will explore the ins and outs of roasting green coffee beans in an air fryer, including the benefits, step-by-step process, and useful tips for achieving your desired roast level. So, get ready to transform those green coffee beans into aromatic, freshly roasted coffee with a rich flavour profile.

Roasting green coffee beans in an air fryer

Step 1: Prepare the Green Coffee Beans

Green coffee beans are raw, unroasted beans that appear green in color. They can be purchased online or from specialty stores. Before roasting, ensure you have high-quality, fresh green coffee beans.

Step 2: Preheat the Air Fryer

Preheat your air fryer to 375 degrees Fahrenheit. This ensures an even heat distribution and allows the beans to start roasting immediately when added to the basket. Most air fryers take about five minutes to preheat.

Step 3: Prepare the Beans for Roasting

Measure 50 grams or about half a cup of green coffee beans. Spread the beans in a single layer in the air fryer basket, ensuring they are not overcrowded. This allows for even roasting and prevents burning.

Step 4: Start Roasting

Set the air fryer temperature to 400 degrees Fahrenheit for roasting. The roasting time will vary depending on your desired roast level, whether light, medium, or dark. For light roasts, roast for 5 to 7 minutes, while darker roasts may take 12 to 15 minutes.

Step 5: Shake the Basket Regularly

During the roasting process, shake the air fryer basket every 90 seconds to ensure even roasting and prevent burning. This is crucial as it keeps the beans from staying in constant contact with the hot metal basket, which can cause charring.

Step 6: Listen for the First Crack

As the beans roast, listen for a cracking sound, known as the first crack. This indicates the beginning of the roasting process. For a lighter roast, stop the roasting process shortly after the first crack, when the beans reach a golden brown color.

Step 7: Adjust for Medium or Dark Roasts

If you prefer a medium roast, continue roasting until the beans turn a medium or dark brown color. For a deep, dark roast, roast the beans until they are black. Remember that air frying can remove the oil from the beans, causing them to go bad quickly, so darker roasts can be tricky to achieve.

Step 8: Remove and Cool the Beans

Once the desired roast level is achieved, remove the beans from the air fryer and let them cool. Spread the beans in a single layer and allow them to sit uncovered for at least 24 hours to release any gases before grinding.

Step 9: Store the Roasted Beans

Finally, store your freshly roasted beans in an airtight container. For optimal freshness, use the beans within two weeks of roasting.

Tips for Success:

• Always preheat your air fryer for consistent and efficient roasting.
• Don't overcrowd the air fryer basket as beans expand during roasting.
• Pay attention to the color, aroma, and cracking sounds of the beans to determine the desired roast level.
• Experiment with different roast levels and timings to find your perfect roast.
• Use a wooden spoon or spatula to shake the beans and avoid damaging the non-stick coating.
• If you plan to roast coffee beans regularly, consider investing in a dedicated coffee roaster for better control and accuracy.

Air fryer settings for roasting coffee beans

Air fryers are a great alternative to traditional roasting methods, which can be time-consuming and require specialist equipment. Roasting coffee beans in an air fryer is a quick, easy, and efficient way to achieve the perfect roast at home. Here are some tips and settings to help you get the best results.

Preheat Your Air Fryer

Before you begin roasting, it's important to preheat your air fryer to ensure consistent and efficient roasting. Set your air fryer to 375°F (190°C). This will ensure that the beans start roasting immediately when added to the basket and help achieve an even roast.

Prepare the Coffee Beans

Measure 50g of coffee beans, which is approximately half a cup. Spread the beans in a single layer on a sheet of parchment paper or directly in the air fryer basket. Ensure the beans are evenly spaced out, not overcrowded, as they will expand during roasting.

Roasting Time and Temperature

Once your air fryer is preheated, place the coffee beans inside and set the temperature to 400°F. Roast the beans for 5-10 minutes, depending on your desired roast level. For a light roast, remove the beans from the air fryer when they reach a golden brown colour. For a medium roast, let them roast until they are a medium to dark brown. For a dark roast, continue until they are almost black.

Stirring and Shaking

To ensure even roasting and prevent burning, it's important to stir or shake the air fryer basket regularly. Shake the basket every 90 seconds or stir every 2 minutes. You can use a wooden spoon or spatula to avoid damaging the non-stick coating.

Listening for the Cracks

As the beans roast, listen for the cracks. The first crack indicates the beginning of the roasting process and occurs within the first 5 minutes. For a lighter roast, stop roasting shortly after the first crack. The second crack will happen one to two minutes later. If you want a darker roast, let the beans roast until the second crack.

Cooling and Storing

Once the beans are roasted to your desired level, remove them from the air fryer and let them cool before grinding and brewing. Store the roasted beans in an airtight container for 1-2 days to allow them to degas, and then use them within 2 weeks for optimal freshness.

Experiment and Find Your Perfect Roast

Each air fryer is different, and roasting times may vary, so it's important to experiment and find what works best for you. You can also try different types of coffee beans, such as Arabica or Robusta, and adjust roasting times and temperatures to create different flavour profiles.

Air fryer vs. other roasting methods

Air fryers have gained popularity as an alternative to traditional roasting methods, especially for small batches. They are a convenient, quick, and easy way to roast coffee beans at home. But how do they compare to other roasting methods?

Air Fryer vs. Oven

The most obvious difference between an air fryer and a conventional oven is size. An air fryer is a compact countertop appliance that usually cooks one dish at a time, while an oven is a full-sized appliance capable of handling multiple dishes or larger portions. Additionally, an air fryer rapidly circulates heated air to cook and crisp up food, whereas a conventional oven uses still air. Some modern ovens do offer air fry capabilities, allowing you to air fry larger amounts of food, which can be useful when serving a crowd.

Air Fryer vs. Convection Oven

An air fryer can be considered a miniature version of a convection oven, as both use a fan to circulate heated air. However, a convection oven has a larger capacity, and air frying optimizes the cooking environment for crispy fried results. If you're preparing multiple dishes or larger batches, a convection oven might be a better option.

Air Fryer vs. Toaster Oven

Toaster ovens typically offer a wider range of functions such as broiling, roasting, and baking, in addition to air frying. They are similar in size to air fryers but provide more versatility in terms of cooking techniques.

Air Fryer vs. Deep Fryer

Deep frying involves submerging food in hot oil or fat, whereas air frying achieves a similar crispy texture by using hot, moving air instead of oil. Air frying is generally considered a healthier alternative to deep frying due to the minimal use of oil.

Air Fryer vs. Microwave

Microwaves use electromagnetism to cook food, while air fryers circulate dry heat to remove moisture from the exterior of foods. Some modern microwaves offer air fry settings, but for optimal results, an appliance specifically designed for air frying is recommended.

Air Fryer vs. Slow Cooker

A slow cooker uses a large pot with a lid to cook food at low temperatures, requiring some amount of liquid. In contrast, an air fryer relies on a dry environment and rapidly circulates hot air to cook food.

Air Fryer vs. Pressure Cooker

An air fryer can fry, bake, and roast using little to no oil, while a pressure cooker is designed for boiling, steaming, and braising. Pressure cookers create pressure by converting liquid to steam that cannot escape. Air frying cannot be done in a pressure cooker due to the lack of an airtight seal, and pressure cooking cannot be done in an air fryer as it cannot build sufficient pressure.

In summary, air fryers offer a convenient, energy-efficient, and versatile option for roasting small batches of coffee beans or other foods. However, they may not provide the same level of control and accuracy as specialized roasting equipment, and the use of an air fryer intended for regular cooking may compromise the flavour of the roast due to aroma transfer.

Pros and cons of roasting coffee beans in an air fryer

Roasting coffee beans in an air fryer has its pros and cons.

Pros

• They are also highly energy-efficient, which is ideal given the current global energy situation.
• With an air fryer, you have complete control over the level of roast you give the beans.

Cons

• Air frying gives roasters less control over roast parameters. While they can follow rough timing estimates or use sight/sound to gauge the roast profile, these methods are not scientifically accurate.
• Air fryers require constant monitoring as beans can burn quickly.
• Air fryers tend to work best for light or medium roasts. While dark roasts are possible, it can be tricky as air frying can remove the oil from within the beans, causing them to go bad quickly.
• An air fryer that is regularly used to cook food may compromise the flavour of the roast coffee due to aroma and flavour permeation.
• Air fryers may not provide enough movement for the beans, resulting in uneven roasting.
• Air fryers may also have inadequate ventilation to handle the smoke produced during roasting.
• The chaff produced during roasting can be a fire hazard if not properly managed.
• Re-roasting already roasted beans in an air fryer will likely result in poor-quality coffee.

Air fryer maintenance and safety

Air fryers are a great, energy-efficient way to cook food. However, as with all appliances, they should be handled with care. Here are some tips for maintaining and safely operating your air fryer:

• Always unplug your air fryer when it's not in use to prevent it from being switched on accidentally.
• Internal and external components of the air fryer get extremely hot during cooking. Protect yourself by using oven gloves when handling the appliance, and protect your work surfaces by placing hot baskets and lids onto a trivet or heat-safe board/mat.
• Never place your air fryer on a tea towel or other soft, flammable surface, as this is a fire hazard.
• Avoid cooking in a non-ventilated area or under over-counter cupboards. Pull the air fryer away from the wall and open windows if you don't have an extraction fan.
• Ensure you leave space around the air fryer for ventilation. Use the 'hand-span rule' to ensure there is at least 5 inches or the average hand length around the device.
• Do not let the air fryer's hot air ventilation openings blow into electrical outlets.
• Regularly check your air fryer for any odd smells, such as burning plastic, which may indicate a fault. If you notice any strange smells, stop using the appliance.
• Some air fryers use 'soft-touch single-sided membrane switches' to control the device. Over time, these can perish and cause the machine to switch on without the user's knowledge. If you notice any sunken or damaged switches or buttons, unplug the device and do not use it.
• Always clean your air fryer according to the manufacturer's instructions. Use only the correct cleaning products, and avoid abrasive products and steel mesh scrubbing pads, especially on tempered glass surfaces.
• Ensure that loose food particles, excess grease, and oil are removed after each use, and that the air fryer is clean before using it again.
• Be careful not to drop or stress components of the air fryer when cleaning, as this could cause wiring harnesses, heating elements, and other internal features to become dislodged, leading to potential overheating.
• If you are roasting coffee beans in your air fryer, be aware that they need nearly constant motion to ensure even roasting. Shake the basket regularly, especially during the first 5 minutes of roasting.
• If you are roasting coffee beans, be aware that they expand during the process, so do not overcrowd your air fryer basket. Place the beans in a single layer to ensure even roasting.
• For optimal freshness, store roasted coffee beans in an airtight container for 1-2 days to allow them to degas, then use them within 2 weeks.
