You definitely want to roast the beans the smart way possible. If you prefer to utilize an oven, that’s also a good idea since that is readily available and offers an affordable method as well. Below is a valuable step-by-step guide for hassle-free oven roasting that you can use.

Step 1: Prepare all the necessary stuff

Basically, there are certain things you should prepare before you start roasting the beans. These include the following:

  • An oven in good working condition with high-temperature capacity up to 500 degrees Fahrenheit
  • A spatula
  • Coffee beans (the green ones)
  • A colander (the metal one)
  • A tray (the perforated kind)
  • A pair of mittens (good quality ones that are perfect for the oven).

Step 2: Examine the oven well


First of all, you must see to it that the oven is suitable for roasting beans. Its window must allow easy viewing while the beans are being roasted. The light must be functioning well so that you can view what’s inside the oven more conveniently. Check its ventilation very carefully as smoke is inevitable while roasting.

Step 3: Begin the process of roasting

The process begins by preheating the oven to as high as 500 degrees Fahrenheit. This is especially recommended for electric ovens. Take note, however, that lower than 500 degrees Fahrenheit is enough for gas ovens.

Step 4: Arrange the beans

You will have to make use of a tray that has perforations as this is the type of tray that goes well with roasting beans. The holes of the tray must not be bigger than the beans as the tray should be able to hold the beans in place. After cleaning and drying the tray, you are now ready to place the beans in the tray. Place the beans in such a way that they don’t pile up and that there is only a single layer of beans in the tray. The beans should be placed next to each other with as little space as possible between them.

Step 5: Make the area well-ventilated as much as possible

Yes. You have to always keep in mind that smoke is part of roasting beans, especially when oven is used. That is why you have to prepare before the smoke spreads all over the interior of your home. You can do this by making sure your space is well-ventilated. If possible, the windows, especially in the kitchen area, should be kept open the whole time so that the smoke can easily get out. Your fans can come in handy as well. Keep them turned on while the beans are being roasted.

Step 6: Put the tray inside your oven

As soon as the oven is set for roasting, you can right away put the tray with the beans in it inside your oven. The middle shelf inside the oven is the best section for roasting, so be sure to use this one. You can rest assured that the temperature doesn’t change and stays the same, especially in this section. So, you cannot put two or more trays at the same time since only the middle shelf can be used as the right section for roasting. If there are more trays to be done, you will have to repeat the step-by-step procedure for each tray.

However, there is one thing that you should remember when using a tray. There is a tendency for some beans to roast more rapidly compared with other beans, especially the ones that are placed near the edges. So, simply remove the tray from the oven, get rid of the burnt contents and stir the contents with the use of a spatula. After which, you should put the tray again inside the oven. Doing this once is enough, but if you had to do it again, you could try only up to the second time.

Step 7: Wait between five to seven minutes

Start counting from the moment you put the tray inside the middle shelf. It should take between five to seven minutes to get light roast beans. You will know since you will be able to hear the initial crack during this time. During the initial crack, you will hear that the beans keep popping for a while. After that, it will stop before you get to hear the next crack. When roasting, there is a change in color. It is best to observe as the green color turns to a lighter shade of brown.

Step 8: Watch out for the next crack

The next crack should sound different from the initial crack. During this time, instead of popping, crackling is another sound that you will get to hear. Once you hear that, you might want to stop roasting as soon as possible, otherwise the beans get over-roasted and will only end up in the trash. On average, it should take approximately ten minutes to finish roasting. However, if you normally prefer a bit darker shade of brown without getting the beans burnt, you may continue roasting a little more, but it should not take more than 1 minute to be safe.

Step 9: Pour the contents of the tray into the colander

After the tray has been removed from the oven, pour the beans into the colander this time so that the temperature of the beans drops eventually. For the beans to cool faster, place the colander in an airy space.

Step 10: Allocate time for degassing

It should take at least a half day before you can use the roast beans and enjoy your homemade coffee as the roast beans need some degassing time, which can take from a half day to two days.

At last, now that you know how to fix a mug of homemade coffee, you don’t have to drive to a coffee shop just to satisfy your craving. You can easily savor your own coffee in your kitchen, dining room, living room or even in your own room!
