Summary: Place the coffee beans in a frying pan. Set the induction cooker to 350 degrees Fahrenheit. Stir the beans continuously, and roast until the “first crack” sounds. It’s the light roast coffee, and proceed further to get medium to dark roast coffee. You must stop before the second crack for a medium roast.

How long does it take to roast coffee beans?

If you’re looking to roast coffee beans, you’ll need to know a thing or two about the process. Here’s a quick guide on how long to roast coffee beans, so you can get the perfect cup of joe every time. 

The first thing you need to know is that the roasting process can take anywhere from 10 minutes to half an hour.

The longer you roast the beans, the darker and more intense the flavor will be. If you like a lighter coffee, you’ll want to roast the beans for a shorter period of time. The other thing to keep in mind is that the roasting process is not an exact science.

Many variables can affect the final product, including the type of bean, the roasting temperature, and the amount of time the beans are roasted. 

So, it’s important to experiment to find the perfect roast for your taste. If you’re new to roasting coffee beans, starting with a light roast is a good idea.

This will allow you to get a feel for the process and experiment with different roasting times. Once you’ve mastered the light roast, you can move on to darker roasts and experiment with different flavors.

So, how long should you roast coffee beans? It all depends on your preference. Start with a light roast and experiment until you find the perfect flavor for your taste.

Understanding the Different Stages of the Roasting Process

Now that you know you can roast coffee at home, you must understand the roasting process. The roasting process transforms raw coffee beans into the delicious roasted beans that we know and love.

Coffee roasting is a complex process, but it can be summarized into five main stages: drying, browning, first crack, second crack, and degassing.


In the drying stage, the coffee bean turns yellow and loses moisture. Green coffee beans start to warm up as you start the roasting. 

After a few minutes, the green color of the coffee bean begins to fade and become yellowish. Moisture evaporates during this stage, and you can see the water vapor.

First Crack:

After 5-10 minutes (depending on the method), the beans make a cracking sound as they expand, and their internal pressure increases. 

You will hear this sound as the sugars inside the beans begin to caramelize. You will also start to see chuff in the beans. 

This is the fastest roast you can get since the coffee beans are lightly roasted at this point and are thus perfect for making a very light coffee.

Various Status of Roasted Coffee Beans


The next stage is browning, in which coffee beans begin to turn brown and develop their characteristic coffee flavor. At this point, you can get a medium-roasted coffee. This is the most popular in the world. 

Second Crack:

They will reach a second crack stage if you continue roasting the beans. The beans will make a second cracking sound and will begin to smoke. This is when you get a dark-roasted coffee. 

The second crack is a good indicator that the beans are done roasting, and you’ll get a medium-dark roast at this point. A few more minutes will yield an even darker roast. However, beyond that, coffee beans will be burnt.


After the beans have reached their desired roast level, they are removed from the heat source and allowed to cool. Allow 12 hours to pass before grinding or brewing the coffee. 

This allows carbon dioxide (CO2) to escape from the bean. It will be very bitter if you grind or brew the coffee too soon. After degassing, store in an airtight container.

As you can see, a lot goes into roasting coffee beans. But don’t let that intimidate you! Roasting coffee at home is a fun and rewarding experience. Plus, it’s a great way to get fresh, delicious coffee. 

Once you’ve roasted beans on your own, you’ll never return to store-bought coffee again. So why not give it a try?

How to Roast Coffee Beans At Home

Now that you know the basics of roasting coffee, it’s time to learn how to roast coffee at home. All you need is a stovetop, an oven, or a popcorn popper. However, I find it most effective to roast in a pan beside a home coffee roaster. 

So, today I’ll elaborate on how to roast coffee beans at home in a pan. The method I follow for roasting coffee is the fry pan method. This is how I roast my coffee bean whenever I need it. 

Here, I’ll use an induction cooker and a frying pan. However, using any stovetop and skillet will provide the same result. So, let’s go through step-by-step how to roast coffee beans without a roaster.

Step 1: Collect Green Beans & It’s Crucial

The first step is to collect coffee beans. It’s an essential part because roasting coffee is all about consistency. To have a consistent roast and flavor, choose beans that are the same size and color throughout. Coffee beans with uniform size and color will yield consistent roast.

Green Coffee Beans

Also, you should only purchase pre-peeled beans. Coffee beans are little red berries picked and processed into coffee. The green bean is hidden within this shell, which must be peeled away. You want the green beans after it’s peeled.

Step 2: Set Up Your Workplace

The second step is to set up your workplace. Make sure everything you need is within reach so that you can focus on roasting the beans and not worry about fetching things. Also, make sure the ventilation is good as there will be smoke.

Set The Temperature At the Stove

You’ll need the green beans, an induction cooker, a frying pan, and a balloon whisk (to stir the beans). I use an induction cooker because it’s easier to control the temperature and has different temperature settings. And I’ll use a frying pan compatible with the induction cooker.

Step-3: Heat Up The Pan

The third step is to heat up the pan. Place the frying pan on the induction cooker and set it to 350 degrees Fahrenheit. This is the temperature that I find works best. So, I set 900 watts that will generate almost 180 degrees Celcius (Close to 350 degrees Fahrenheit)

As the stovetop and pan may vary for your case, I’ll suggest adjusting the temperature to find the optimum settings. Your main intention should be not to burn the beans. Therefore, you can start with a low set first.

Collect Green Beans for Roasting

Once the pan is heated, add the green beans. You’ll want to keep stirring the beans so that they roast evenly. If you have a lot of beans, you may want to consider roasting in batches so that all the beans are roasted evenly.

Step 4: Roast The Beans

The fourth step is to roast the beans. This is where you’ll want to pay attention as it’s easy to burn the beans. The roast level is a personal preference, and you can experiment to find what you like best.

Light Roast Coffee Beans

As you continue stirring the beans, you’ll notice beans are changing color, turning yellowish from green. After a while, you’ll also hear the sounds of beans popping like popcorn. That’s the ‘first crack,’ and beans are lightly roasted. If you like light roast, you can stop here.

Medium Roast Coffee Beans

For a medium roast to dark roast, continue roasting. Coffee beans will now turn a brownish color and start to smoke. You’ll also hear the ‘second crack,’ which sounds like firecrackers. 

The second crack happens when the beans are medium-dark roast. If you want to stop at a medium-dark roast, take the beans off the heat when you hear the second crack. 

Medium-Dark Roast Coffee Beans

However, if you prefer a medium roast, you must stop before the second crack and when the coffee beans take brownish color.

Step 5: Continue for a dark roast

After the second crack, continue roasting the beans for a minute. The beans will now take on an oily texture and dark brown color. If you want to achieve a dark roast, this is the point where you want to stop. However, be careful not to burn the beans.

Dark Roast Coffee Beans

The beans will now be fragrant, and you’ll notice a strong coffee smell. Remove the pan from the heat when you’ve reached the desired roast level.

Step 6: Let The Beans Cool

The sixth and final step is to let the beans cool. Once you’re done roasting the beans, pour them into a metal colander or baking tray. Stir the beans around so that they cook evenly and quickly.

At this point, remove the chuff from the bean. There are many ways you can do that. The chuff rises to the top as I shake it in the colander and blow it away. Remove as much as you can.

You’ll have to leave the bean out for 12 hours to off-gas carbon-di-oxide once cooled. If you store them immediately after it is cooled, the beans won’t get enough time for degassing, which will cause the beans to deteriorate quicker.

Once the beans are cooled, you can store them in an airtight container. I like to keep mine in a mason jar. And that’s it! You’ve now roasted coffee beans at home.

Wasn’t that easy? Now you can enjoy a cup of freshly roasted coffee. Roasting your own beans also allows you to experiment and find the roast level that you like best.

Can you roast coffee beans in the oven

So, while you can roast coffee beans in the oven, it’s not the best method. The problem with roasting coffee beans in the oven is that getting the perfect roast is difficult, and it’s a slower process. In addition, it can be very smoky.

Please see the video below if you want to know how to roast coffee in the oven.

The Benefits of Roasting Coffee Beans at Home

Now that you know how to roast coffee beans at home, you might be wondering if it’s worth the effort. After all, you can just buy roasted coffee beans at the store. However, there are a few benefits to roasting your own beans.

First, you’ll be able to create a unique flavor. When you roast your own beans, you can experiment with different roasting times and techniques to create a flavor that’s perfect for you.

Second, you’ll be able to control the quality of your coffee. When you buy roasted beans from the store, you don’t always know how long ago they were roasted. This can affect the flavor of your coffee.

However, when you roast your own beans, you can be sure they’re fresh and of the best quality. Finally, roasting your own beans is a fun and rewarding experience. 

It’s a great way to experiment with different flavors and learn more about coffee.

If you’re a coffee lover, roasting beans on your own is definitely worth the effort. Not only will you be able to create a unique flavor, but you’ll also be able to control the quality of your coffee. 

Is it cheaper to roast your own coffee?

When it comes to coffee, there are plenty of ways to save money. One way is to roast your own coffee. But is it cheaper to roast your own coffee?

The answer is yes and no. It all depends on how you roast your coffee and what you use. If you want to save money, you can roast your own coffee.

But it all depends on how you do it. For example, using any of the methods mentioned besides a specialty coffee roaster will be cheaper. But there are some drawbacks to those methods. For one, it can be challenging to control the temperature.

This means that you could end up burning your coffee beans. Another drawback is that it can be difficult to get a consistent roast. This is because it’s complicated to get the same constant heat as a specialty coffee roaster.

So, if you want to save money, you can roast your coffee. But you need to be careful about how you roast it. If you don’t make it right, you could end up burning your coffee beans.

And if you use a specialty coffee roaster, it will be more expensive.

How to roast coffee beans with flavor?

When it comes to coffee, there are two types of beans: Arabica and Robusta. Arabica beans are used in most specialty coffees and are known for their superior flavor. On the other hand, Robusta beans are used in lower-quality coffees and have a more bitter taste.

If you want to roast your own coffee beans and create a unique flavor, Arabica beans are the way to go. The first step is to choose the right beans. If you’re unsure which type of beans to buy, ask your local coffee shop for recommendations.

Once you’ve selected your beans, it’s time to start roasting. You’ll need a coffee roaster, which you can buy online or at a specialty kitchen store. However, you can follow the method I’ve described above. 

Then, add the beans and let them roast for about 20-35 minutes. The beans should turn a dark brown color when they’re done. Once the beans are roasted, let them cool for a few hours before grinding them.

Where to buy green coffee beans for roasting

There are a few different ways to buy green coffee beans for roasting. You can buy them online, from a specialty coffee shop or some grocery stores.
