Edible chestnuts will amaze you with their possibilities in modern Czech cuisine.
Edible chestnuts are perhaps more associated with autumn than any other fruit. Their aroma, wafting from street stalls or the oven, can instantly evoke nostalgic memories of chilly evenings, warm scarves, and walks under falling leaves. Although often spoken of as a seasonal delicacy, edible chestnuts have surprisingly rich uses and play a significant role in terms of nutrition and health. What are their effects, how can they be prepared, and why should they find their way into more than just one autumn recipe?
What exactly are edible chestnuts?
Edible chestnuts come from the sweet chestnut tree (Castanea sativa), which grows mainly in the Mediterranean, but also in some areas of Central Europe. Unlike the inedible horse chestnuts that we know from city parks, the fruits of the chestnut tree are nutritious, tasty, and safe to consume. It's no wonder they have been an important part of the diet in areas where grain cultivation was challenging – chestnuts contain enough carbohydrates and fiber to replace bread or potatoes.
What are the health benefits of edible chestnuts?
Edible chestnuts are unusual in that, although they taste sweet, they have a relatively low fat content – compared to walnuts or hazelnuts, for example. They are rich in complex carbohydrates, which release slowly in the body, helping to maintain stable blood sugar levels. They also contain vitamin C, which is exceptional among nuts and seeds, and a significant amount of B vitamins, especially B6, which supports the proper functioning of the nervous system.

Among minerals, they are rich in potassium, magnesium, and copper. Potassium is important for the heart, magnesium helps manage stress, and copper supports immunity. Thanks to their high fiber content, they support digestion and the proper function of the intestines. They are naturally gluten-free, making them perfect for celiacs.
And perhaps most surprisingly – chestnuts are used in traditional Chinese and folk medicine, where their consumption is recommended, for example, in cases of fatigue, arthritis, or a weakened spleen. Some studies suggest that thanks to their composition, they may also have antioxidant effects.
How to prepare edible chestnuts?
The secret to successful preparation lies in one small detail that is often overlooked: chestnuts need to be scored before cooking. Otherwise, they will explode when baking or boiling, making a mess in the oven or pot.
There are two basic ways to prepare edible chestnuts: boiling or baking. Both have their advantages. Boiled chestnuts are softer and are suitable as a base for purées or soups. Baked ones have a more intense flavor and literally smell of autumn.
Steps to prepare baked chestnuts
- Wash and dry the chestnuts.
- Use a sharp knife to score each fruit on the top side in a cross – only the skin, not the flesh.
- Preheat the oven to 200°C.
- Arrange the chestnuts on a baking sheet (preferably lined with baking paper) and bake for 20–25 minutes.
- Peel them while still warm – it's easier than when they're cold.
Baked chestnuts can be eaten as they are, with a little salt or butter. But their use is much broader – they can be added to salads, creamy soups, stuffing, or even desserts.
Recipe for chestnut purée
Looking for a simple and healthy recipe using edible chestnuts? Purée is a great choice. It can be used as a side dish to meat, in vegetable plates, or as a base for a sweet cream.
Ingredients:
- 500 g boiled or baked edible chestnuts (peeled)
- 200 ml plant-based or cow's milk
- a pinch of salt
- optionally: a teaspoon of butter or a drop of vanilla extract if preparing a sweet version
Instructions:
Place the chestnuts in a blender, add the milk and other ingredients. Blend until smooth. Add more liquid as needed. The purée should be creamy and smooth. It will keep in the fridge for several days and can also be frozen.
Edible chestnuts in world cuisines
In Italy, edible chestnuts are a common ingredient. They are prepared in many ways – from simple roasting to more elaborate desserts like marrons glacés, or candied chestnuts. In France, they make the famous purée “crème de marrons," which is served with pancakes or used in cakes. In Japan, they are part of the New Year dish kurikinton, a sweet potato and chestnut dish symbolizing happiness and prosperity.
In our country, we are still mostly limited to consuming roasted chestnuts, but that is slowly changing. With the growing interest in seasonal, novel, and nutritious foods, chestnuts are finding their place in modern Czech cuisine.
A natural and sustainable choice
Edible chestnuts are not only tasty and healthy – they are also an environmentally friendly food. Chestnut trees require almost no pesticides when cultivated, have a long lifespan, and help retain water in the landscape. In some areas of Europe, their cultivation is becoming part of projects to restore extinct orchards and increase biodiversity.
Moreover, if you buy chestnuts from a local grower or collect them in a verified area, you support the local economy and reduce the carbon footprint associated with importing. From a sustainable kitchen perspective, chestnuts are an ideal ingredient – seasonal, nutritious, and with minimal environmental impact.
Chestnut Feast in the Beskids
Every autumn, a small village in the Beskids hosts a festival called "Chestnut Feast." The local bakery offers bread made with ground chestnut flour, local mothers prepare chestnut muffins, and a thick soup with chestnuts and root vegetables is served in the cultural house. The biggest attraction, however, is the workshop for children, where they can not only prepare roasted chestnuts themselves but also decorate them with natural painting. As one of the organizers says: “Chestnuts are a symbol of autumn. The goal is to show people that even simple and traditional foods can be modern and tasty."
And that is the key to their popularization – understanding that chestnuts are not just a festive treat, but a complex food with a rich tradition and modern uses.
The great news is that today, you can buy not only fresh fruits but also chestnut flour, purée, or chestnut paste – ideal for those who want to experiment with new flavors or are looking for alternatives to gluten, sugar, or traditional flour.
So next time you're strolling through a misty autumn forest or just shopping at the market, try giving chestnuts a chance. Not only will they warm your hands, but they might also find a permanent place in your kitchen.
