How to Roast Coffee Beans in an Air Fryer: The Ultimate Guide!

You’ve probably used a coffee roaster for all of your coffee needs in life. But what if I told you that you don’t need a coffee roaster to roast your coffee?

What if I told you that you could actually use an air fryer to produce similar results?

Are you curious? Let’s dive into exactly what the benefits are and how to roast your coffee beans using an air fryer.

This is going to be a comprehensive review and how-to article on everything you need to know about roasting your coffee beans using an air fryer.

Can you roast coffee beans in an air fryer?

You can roast your coffee beans in an air fryer relatively easily. It takes far less time than it would if you were using a traditional oven to roast your beans because the space that is being heated is smaller. You also have a bit more control over the roasting process and can check on your beans from time to time while they roast to ensure you get the color and flavor that you want.

Why home roast your own coffee beans?

There are many reasons to home-roast your own coffee beans.

The first, and most obvious, reason is that it’s convenient. You can roast your beans in an air fryer and have them ready for use in just a few minutes.

Store-bought roasted beans are often stale, but using freshly roasted beans makes all the difference in the flavor of your cup of coffee. In addition, you get to choose the flavors and aromas that you like best.

Coffee only has flavor for a week or so, so it’s important to roast your own beans if you want to enjoy the freshest possible cup of coffee.

Roasting your own beans also gives you full control over the roasting process.

You can adjust the temperature and time to create the perfect roast for your taste preferences.

Pre-roasted coffee beans are more expensive than roasted ones, so roasting your own at home can save you money.

Finally, drinking a cup of Joe that you roasted yourself can be incredibly satisfying. It’s a great way to connect with the ritual of making coffee and enjoy all the flavors and aromas that come with it.

How to roast coffee beans in an air fryer?

There are a few different steps that you need to take to properly roast your coffee beans in the air fryer. Here is the process:

1. Prepare your coffee beans.

The first step is to prepare your beans. If you have beans that are already shelled and ready to be roasted, you are good to go. You want to make sure you have the right beans for your preferred taste and that they are ready to be placed in the air fryer.

2. Preheat the air fryer.

Preheating your air fryer is a must. This will help to get those beans roasting in the first second that they are put in. You want to set your air fryer to the highest heat that it can safely run at. This will help roast the beans properly.

3. Arrange your coffee beans on the air fryer tray.

You then need to place your fresh beans in the air fryer. You want an even, single layer to prevent the beans from roasting unevenly. You want a single layer that is going to allow the beans to roast evenly without needing to stir them. If you have to make a double layer or you have too many beans to make a single layer, you can always open the air fryer and stir your beans a few times during the roasting process.

4. Roast your coffee beans to your preference.

Roast your beans for about 8 to 10 minutes, depending on how roasted you want them to be. For a blonde roast, you would only put them in for about 8 minutes, with a darker roast going for at least 10.

5. Let the beans sit.

Allow your beans to cool fully before you try to store them. You want to ensure that your beans are fully dried before you try to store them anywhere. If you do try to store them when they are still hot, they can produce sweat, which can then lead to condensation in the container, which can lead to mold and to your beans going bad.

6. Store your roasted beans.

Storage of your beans is a must. You want to make sure they are stored in a cool, dry area with an air tight container. The more air tight your container is, the better they are going to last and the longer the flavor is going to last as well. An air tight container also keeps your beans from going stale and from tasting less than delicious.

How long does it take to roast coffee beans in an air fryer?

The time it takes to roast coffee beans in an air fryer varies depending on the batch size. For smaller batches, the process will last about 8 to 10 minutes, while larger batches will take up to 16 minutes. After you have the roast that you prefer (light, medium, or dark), mark how long it took and continue on with as many batches as you need for all of your fresh-ground coffee needs.

Coffee beans require time to de-gas after roasting. This is an important step that must be followed in order to not release as much CO2. Allow your coffee beans to cool for 24 hours after roasting in order to not release as much CO2.

What temperature should you roast coffee beans in an air fryer?

In order to roast coffee beans in an air fryer, you need to set the temperature between 370 degrees and 540 degrees Fahrenheit. Unfortunately, most air fryers will only go as high as 450 degrees Fahrenheit. However, this will likely be enough to roast your coffee beans. This will produce the best results for your coffee beans!

Make sure that you preheat your air fryer for 3 minutes before beginning the roasting process, and then set the machine to its highest, yet safest, setting. Fill your air fryer with fresh coffee beans before starting the roast.

The higher temperatures will create pressure inside of the beans, which will change their structure. Roast for 8 to 10 minutes, stirring a few times throughout, before pulling the basket out. You’ll know they’re done when they’re a light brown color and make some noise when knocked together!

How to tell if the coffee is roasted enough

There are a few ways that you can tell if your beans have been roasted enough. When beans are roasted, they will crack. The first crack is going to be for a very light roast. The second crack will occur after a few more minutes and will show that your beans have roasted to a medium roast. You can often tell if a bean is roasted enough by the smell and color. The darker the bean and the fresher the scent, the better roasted it is. If you over roast a bean, it will start to smell acrid and not like fresh coffee at all.

The crackling sounds

The first crack usually occurs within a minute or two of your roasting. The second crack will follow shortly after, about 30 seconds after the first. This is the bean expanding as the water leaves the bean and it dries out. This is a necessary sound, and though it might be a bit intimidating, there is nothing to worry about.

Is roasting coffee beans in an air fryer toxic?

There is some concern that roasting coffee beans in an air fryer may release chemicals that are toxic to humans. The concentration and exact chemicals released depend on the temperature, duration, type of bean, and grinding process. Some of the chemicals released include alpha-diketones, acetoin, and diacetyl.

It’s important to keep in mind that the risk of roasting coffee beans is not exclusively geared towards air frying. Any type of roasting of coffee beans has the potential to produce such chemicals.

Roasting coffee beans in an air fryer may cause the user to inhale the chemical alpha-diketones. These fumes are known to cause irritation to the eyes, nose, and throat. They can also cause headaches, dizziness, and nausea.

In a study based on a coffee company, it was found that the coffee production facilities package recently roasted coffee in permeable bags, exposing packaging employees to fumes. Roasting coffee beans creates a buildup of chemicals that pose a health risk for packaging employees when they grind them up.

The repeated roasting and grinding of beans during quality control and testing exposes employees to the fumes of flavorings such as diacetyl. Employees may not be aware that they are exposed to these fumes because they are consuming small amounts of coffee in a confined area.

The natural by-product of coffee, acetoin, releases chemicals which sometimes become dispersed in the air when roasted or ground in small quantities.

Until recently, manufacturers believed that exposure to diacetyl would only occur during coffee production. Fermentation processes produce diacetyl naturally, and the FDA suggests this compound is safe for consumption in small amounts. However, recent research shows that inhalation of diacetyl can result in lasting health effects.

Can you roast coffee beans more than once in an air fryer?

What is the second crack you hear when roasting coffee beans in an air fryer?

The second crack is when oils begin to migrate from inside the beans to outside of them. The cells of the cellular matrix fracture at a certain temperature, allowing oils to move outward.

To roast coffee beans, you want to catch them before the first crack of their cellular matrix occurs-which should be audible and visible. Once the first crack occurs, it can come on fast, and there’s only a bit of time before the dark roast takes over.

The second crack you hear when roasting coffee beans in an air fryer is the beginning of a medium roast. It will take anywhere from 12 to 15 minutes to achieve a dark roast if the process doesn’t start with a first crack, but eventually you’ll hear this second one and know that it’s been achieved.

What ingredients can you add to cook coffee in an air fryer?

There is really no way to add flavor in the air fryer as you are roasting your beans. The flavor in flavored coffee comes from syrup that is added to the coffee after it has already been roasted. You can roast your beans in the air fryer and then add a small amount of syrup as you grind your beans for use. You can also add flavored syrup to your brewed coffee to give it more flavor.

Can you air fry coffee beans on a silicone mat?

You can roast your beans on a silicone mat in the air fryer. Since coffee beans do not give off much oil when roasted, it really is not necessary. Another thing to consider is that a silicone mat is going to prevent air from circulating freely, so it may take longer to get your beans to the perfect roast if you do use something under them in the air fryer.

Best air fryer for roasting coffee beans

Either type of air fryer is fine when roasting coffee beans. The real thing you want to keep in mind is how you are roasting. With both basket and oven-style fryers, you want to make sure you have a high enough heat, that the beans are either in a single layer or that you are stirring them, and that you are watching to make sure you do not over roast.
