The answer to this common question could not be more emphatic: of course yes. And, in fact, it must be clarified that the original recipe is prepared without this ingredient.

In the first moment of cooking, the onions lose much of their water. As a result of this, they become soft and lose volume. Likewise, begins to release its recognizable aromas and flavors.
Then, when there is almost no water left, the temperature increases, and caramelization and, in most cases, the Maillard reaction begins.

- Olive oil (preferably extra virgin): 6 to 7 tablespoons
- Half a cup of water (125 cubic centimeters)
- A pinch of baking soda (optional)
- A level teaspoon of salt
- 4 to 5 large onions
The following utensils will be required throughout the process:
- A large knife
- A large frying pan or wok
- A wooden spoon for stirring
- A sterilized glass container for storing the jam
- A cutting board (preferably wooden, not plastic)
Here’s how to make it
Preparing sugar-free caramelized onions is a simple process. However, it requires full attention at every stage.
1. Choosing the onions
Of course, we must select and buy some nice onions. The bigger and fresher, the better.
It’s important to make sure that they don’t have bruises, damaged parts, or holes. It is important to pay attention to the smell, as the smell can reveal if it’s beginning to decompose.
There are several types of onions: yellow, purple, French onions, and spring onions. For the recipe we are going to prepare, white onions are recommended. This isn’t only because they’re the largest, but, together with the purple ones, they’re the ones that contain more natural sugar.
2. Wash them well
Although we’re going to use the inner layers, it is advisable to wash all the food well. Especially because they grow in the soil and may have come into contact with various chemicals.
3. Peel and cut them
First, cut the onion crosswise, leaving four large portions. The first layer or two, i.e. the outermost layers, are removed or discarded. Then, cut the onions into julienne strips, making sure they aren’t too thin.
4. Heat the oil and the onion
Put the frying pan or wok over a low heat and pour in the olive oil. Once the oil is hot, add the chopped onion.
Make sure that the julienne strips are well spaced out so that they don’t clump together. Then, sprinkle the salt. Keep the flame low throughout the preparation process.
At first, when the onion begins to lose water, it will look transparent. But then, the water evaporates and this is when caramelization begins, where it turns from white to golden brown. Then, the sugars are released, giving the characteristic flavor and aroma of this recipe.
The process takes time, about two and a half hours. Patience is required. There are recipes that don’t take as long. During the first hour, it’s necessary to turn the julienne strips every now and then, using a wooden spoon. In the same way, you must ensure they’re all cooked and browned equally.
And, in the last hour of the process, the attention must be greater, as you can’t let them burn. The golden hue will change to a caramel color, a little darker. The texture will also change, feeling soft. This indicates that the sugar-free caramelized onions recipe is ready.
Drain the excess oil and store them in a sterilized glass container, to be consumed when desired. They can be kept easily for up to a week.
Some tips and recommendations
Apart from the above indications, there are situations to pay attention to when preparing sugar-free caramelized onions, so that the quality of the product is guaranteed. Among the recommendations to be taken into account are the following:
- If you notice that the onion is drying out, a little water can be added.
- A pinch of bicarbonate, added when it’s finishing the caramelization process, helps to preserve it a little more.
- Another optional ingredient that can be added is vinegar: a teaspoon can enhance its flavor, giving it a slightly sweet and sour touch.
- Some people also prefer to add oregano or other spices, such as black pepper, for a more explosive flavor.
- Caramelized onion without sugar reduces its volume quite a bit. So take precautions and always calculate a little more than you think you will need.
- When it’s time to serve, heat it up a bit and it’ll taste as if it were freshly prepared.
