What Are Chestnuts?
Chestnuts are trees and shrubs in the genus Casanea, in the beech family of Fagaceae. In In English, people use the name of this plant to describe the deliciously edible nuts they produce.
The Chestnut Blight:
In 1904, the fungus Cryphonectria parasitica was first introduced to the United States through the integration and cultivation of the Japanese chestnut tree for commercial use. Unfortunately, the American chestnut tree lacked resilience against the invasive fungus carried in the Japanese chestnut trees. By the 1940s, the fungus whipped out almost all of the mature American chestnut trees.
This part of American (and European) tree history is known as the chestnut blight.
Chestnuts in South Korea:
In Korea, people refer to the chestnut plant as ‘bamnamu’ (반나무). The term is made of two words ‘bam’ (밤) meaning ‘chestnut,’ and ‘namu’ (나무) meaning ‘tree’. They refer to the edible nuts as ‘bam’ (밤).
During the winter, street vendors sell hot, freshly roasted chestnuts in markets and on street corners. They prepare them using a stirring machine that cooks the constantly churning chestnuts over a fire. Then, they pop them in a paper bag before handing the perfectly roasted chestnuts over. When I lived in South Korea, this was one of my favorite treats. I always search for a vendor when I travel home to Korea during the winter to visit our family.
Roasted Chestnuts Ingredient List:
Below, I list the ingredients used to make this very basic recipe:
- Chestnuts
- Water
I recommend serving roasted chestnuts hot with two dipping ingredients:
- Coarse-Grain Salt
- Softened Butter
Roasted Chestnut Tips & Tricks:
Here, I list some helpful tips & tricks to help you roast these chestnuts. If you have any questions, comment below or email me at [email protected]! I hope these tips help!
- First, always wash your chestnuts. While you do not eat the shells, they have gone through many hands during preparation, transportation, and stocking of the produce. It is always better to wash your food in your kitchen!
- Then, soak your chestnuts in water for at least 30 minutes. This softens the shells which comes in handy when you are scoring them. Further, it helps the process of steaming the chestnuts.
- Scoring the outside of the shell is important for safety. Slice an X through each shell of your chestnut. As much as possible, try not to pierce the meat of your chestnut. This keeps your chestnuts from popping or exploding in the oven or on the stove.
- If you are unsure that the chestnuts are done, try peeling one and eating it. If it still has a crunchy texture, it is not done. These chestnuts should be soft.
- Serve your chestnuts hot! Let your chestnuts cool slightly in a wrapped towel. Once cooled enough to touch, peel your chestnuts while still warm.
How to Roast Chestnuts in the Oven?
- Preheat your oven to 400°F. Place the scored chestnuts on a tray. The X should face upward.
- For larger chestnuts, roast for approximately 15-25 minutes. For smaller chestnuts, roast for 10-15 minutes.
Roasting chestnuts is not an exact science–it may take more or less time depending on your oven and nuts. So, please remember to keep an eye on these as they cook! Do not rely on the timer and run around doing other activities.
If you wait until the shells are charcoal brown or black, you have overcooked your chestnuts!
How to Roast Chestnuts on the Stove?
- Heat your pan on medium heat. Once hot, place your chestnuts on the pan. Once again, the sliced side should face upward.
- As you roast your chestnuts, shake your pan occasionally to move the chestnuts around. You will know that your chestnuts are cooked when the shell peels backward, and your kitchen smells nutty.
Note that the stovetop process takes longer than the oven method.
Roasted Chestnuts Frequently Asked Questions:
Now that we learned about some tips & tricks, I want to answer some questions you may have about this recipe! If I do not answer your question, feel free to leave a comment in the section below or email me at [email protected].
What Do Roasted Chestnuts Taste Like?
The meat of roasted chestnuts tastes a bit sweet. In many ways, roasted chestnuts resemble a Korean or Japanese sweet potato more than a nut in flavor. When roasted, the nuts gain a soft, chewy, and tender texture. They retain heat for an extended period–making them a perfect winter treat!
What Should You Eat With Roasted Chestnuts?
As I stated above, I recommend serving coarse-grain salt and softened butter with roasted chestnuts. Both taste delicious spread over the top.
I also enjoy roasted chestnuts completely plain!
Does This Recipe Contain Major Allergens? (Gluten, Soy, Etc.)
Before listing all of the major allergens, I want to state that all of my recipes are naturally gluten-free. On this blog, I only use and recommend gluten-free ingredients and brands. That being said, I list gluten as a potential allergen when necessary– this is because many Korean ingredients (such as soy sauce, gochujang, and doenjang) contain gluten unless you specifically buy gluten-free versions. Not only is this true for gluten, but it is true for other major allergens as well. As such, I always list allergy substitutions in the next section of my post.
This recipe does not contain 8 of the 9 major allergens. It does not contain:
- Peanuts
- Milk (Dairy)
- Wheat (Gluten)
- Soybean
- Fish
- Crustacean Shellfish
- Eggs
- Sesame
- Tree Nuts
This recipe does contain 1 of the 9 major allergens. It can contain:
- Tree Nuts
Allergy Substitutions or Omissions:
For those with a tree nut allergy:
Unfortunately, the single ingredient for this recipe is chestnuts. Therefore, it contains tree nuts. If you have a tree nut allergy, you cannot learn how to roast chestnuts.
Is This Recipe Vegetarian or Vegan?
Excitingly, this recipe only contains chestnuts. Therefore, it is naturally vegetarian and vegan!
How Do I Store Leftover Roasted Chestnuts?
To store leftover chestnuts, place them in an airtight container and store them in the refrigerator. You can then reheat them quickly in the oven before eating!
Where Can I Buy the Chestnuts for This Recipe?
Excitingly, you can buy all the chestnuts during the winter at many grocery stores (such as Whole Foods).
If you cannot find them in your typical grocery store, try shopping at your local Korean or Asian market (such as H-Mart). During the winter, these markets often carry chestnuts.

Directions
- Oven Roasting
- Preheat your oven to 400°F.

- Place your scoured chestnuts in a single layer on your baking sheet. The X should face upward.
- Roast your chestnuts for 15-30 minutes, checking your oven and nuts often. Chestnuts are done when your kitchen strongly smells nutty and the scoured sections of the shells curl back.
- Remove your chestnuts from the oven and place them into a towel to slightly cool. Once cool enough to touch, but still warm, peel back and eat.
- Serve chestnuts with optional salt and/or butter.
