Did you know that toasting coffee at home is not only possible but also very easy? Roasting coffee at home is a forgotten practice – to say the least, it was in the past was widespread in our country and allowed every family to get their coffee roasted from green coffee beans to excellent homemade espresso.

Not many people know that even today it is still possible to roast coffee at home using the simple appliances we have in our kitchen, first of all, the common oven with which we cook some of our favorite dishes. Let’s see together how.

Why roast your coffee at home?

Before getting to the bottom of the available coffee roasting methods, it is good to answer one of the most common questions: given the availability on the market of excellent roasted coffee, why should I roast my coffee at home? The answer is simple and reminds a bit of what we talked about in the last article about the differences between ground coffee or coffee beans: the answer to the question, the freshness, and aroma.

Yes, because when you roast your coffee at home you can ensure that every cup of espresso you prepare is fresh and personalized to your taste. However, it is often a job to be left to coffee professionals, unless you have a lot of time and desire to study because roasting coffee is a process that takes time and experience.

How to roast coffee at home with the oven

When you see it step by step, homemade coffee roasting is an unexpectedly easy method, more than you might think.


The first step is to choose the machinery with which to toast your green coffee beans. The fastest method is the one that sees the use of a common homemade oven because you can find it in every kitchen, but there are others that, for example, involve the use of a popcorn machine or even specific machinery such as a coffee toaster.

The second step for homemade coffee roasting is undoubtedly to get green coffee beans: although the trend of homemade coffee roasting is very widespread especially in the Nordic countries and in the Anglo-Saxon world, different solutions allow you to buy your beans online in larger or smaller quantities also in our country.

Now that we have decided to use our home oven to roast our coffee and we have ordered the green beans, only two tools are missing: get a perforated baking pan, like those in which pizza is prepared, and a sieve to help your beans during cooling.

Now you have everything. It’s time to start the actual process. 

Here’s how to roast coffee beans in the oven, step by step:

  • Set the oven temperature to maximum.
  • Place a good amount of green coffee beans on our perforated baking tray, making sure they remain on one layer anyway, so that the heat envelops them completely.
  • When the oven has reached the maximum temperature (this is usually indicated by the indicator light going off) insert the tray with the beans in the middle of it.
  • Observe the beans: after about 5 minutes you will notice how the coffee begins to open, sometimes with a small crack-like sound, and to change color: the color will become darker and darker as the roasting process proceeds. With experience, you will learn to recognize the roasting level and color of your favorite coffee.
  • When the coffee beans have reached the desired color, it is time to take them out of the oven. It is recommended that the roasting process never lasts longer than 20 minutes.
  • Pour the coffee beans into a sieve for cooling.
  • Your home-roasted coffee is now ready to be ground and enjoyed.

Roasting coffee at home in a frying pan

It is the simplest and most basic method, and also one of the oldest. In some countries, it is still used, such as Ethiopia, and is a good way to start. All the equipment you need is already at home: a large metal pan, a long handle ladle, a strainer, a large tray or fountain, and a spray with a diffuser. In addition to the kitchen fire, of course.


It is as simple as filling the pan with a good layer of green coffee beans, without going over, and heating them over medium heat without stopping stirring until you get the desired degree of roasting. Then you have to quickly remove them to the strainer, spray them with a tap of fine cold water, and then spread them on the tray.

The kitchen must be well ventilated or with the smoke extractor working, and let the grains cool down completely in another room, better next to an open window. You can also use a working fan in front of the beans.

Roasting coffee at home with a popcorn machine

If you like popcorn you are in luck, now you have another excuse to get a home machine. This system is a little more technical and fast and requires the use of a long handle wooden spoon, a fine-mesh strainer, and a metal one with a foot or a metal pot.

The green coffee beans are poured directly into the machine-like popcorn, placing the large strainer or pot under the nozzle. Depending on the machine we will use about 75-85 g of coffee beans. During the first minute you have to stir, then residues will start coming out of the husks. This is a quick process, which can take between 4 and 8 minutes.

The roasting process with these devices is very fast, usually 4/7 minutes for a light roast, 7/8 minutes for a darker roasted coffee.


The amount of coffee you can roast is about 75/85 gr of green coffee, it depends a lot on the roasting tank of the roaster, and considering a weight loss during the roasting of about 20% we will have 60/70 gr of roasted coffee.

One very important thing before continuing with the reading of this post, and maybe start thinking about buying a Popcorn machine we would like to warn you that if you use it to roast coffee the warranty the machine expires immediately, and if you do it at your own risk! 

Cooling the coffee

A container that we use to collect the films that will come out during the roasting process from the popcorn chute.

An oven glove to grab the machine at the end of roasting and discharge the beans into the strainer.

Notice: If you roast coffee with a PopCorn machine you do it “at your own risk” however we recommend some measures that minimize the risk of fire ( often happened due to negligence of the “roaster”).


Do not leave the “roaster” unattended during the roasting process, keep always an eye on the reactions of the coffee.


Roast coffee outdoors whenever possible.

If a fire starts inside the machine, unplug it and turn it off with a small fire extinguisher or bucket of water.
