How to Cook Chestnuts in the Microwave

For New Yorkers, roasted chestnuts sold in bags on the streets mean autumn and winter. However, this delicious snack is a seasonal favorite in Native American regions, Europe, and Asia. If you have raw chestnuts you want to pop into your mouth or use in recipes, it’s essential to cook them first to remove the bitterness. 

To cook chestnuts in the microwave often, you have to follow a few easy steps:

  1. Using a knife, score the chestnuts, i.e., make incisions on the rounded side of the chestnut shells in the form of a cross (X). 
  2. Line anything between 5 and 25 chestnuts on a shallow microwavable glass plate.
  3. Microwave the chestnuts on High for 3-4 min, and keep stirring the nuts every minute. 
  4. Cook the nuts for 5 min if your microwave cannot power up beyond 750 W.
  5. Let the chestnuts rest for another 5 min before peeling off the skin. 

You will know that the chestnuts are ready when the skin becomes soft and the nuts slip out of the skin easily upon squeezing them. It’s best to start peeling when the chestnuts are still a little hot. That’s when it is easiest to peel them. Just make sure that they are cool enough for you to handle them after cooking. 

If you have more time, there’s an extra step you can add. After cutting the crosses on shells, place the chestnuts in a bowl and cover them with water. Then, allow them to soak for about 20-30 minutes and drain the water before microwaving them at 750 W. This will make the peel softer and prevent burning.

Other Ways of Cooking Chestnuts

The fastest way to cook chestnuts is by popping them in the microwave and setting them to roast for 3-5 minutes. But what will you do if you do not have a microwave oven in your kitchen? Surely, it doesn’t mean you should not enjoy chestnuts. Instead, you have to use the traditional methods of cooking them.

  •  Cooking Chestnuts in the Oven

Most people who prefer cooking in traditional ovens easily cook their stock of raw coconuts in the oven. There are two ways of doing this. You can either directly bake the nuts by baking them in the oven. Or you can boil the chestnuts in water first and then bake them to cook the chestnuts twice.  

To bake chestnuts in the oven, follow the steps below – 

  1. Using a sharp knife, score the chestnuts.
  2. Preheat the oven to 425 F. 
  3. Line the chestnuts on a baking rack in one layer. 
  4. Bake the chestnuts for about 20-30 min. 
  5. Let the chestnuts rest for 5 min before attempting to peel them.  

Before baking the chestnuts in the oven, you can boil them in the following way – 

  1. Heat water at 250 F for 10-15 min. 
  2. Then, place the scored chestnuts in hot water. 
  3. Cook the chestnuts for about 15-20 min and pull them out.
  • Cooking Chestnuts on the Stovetop

If you do not have a traditional oven at home, either, don’t worry! You can still cook the chestnuts on the stovetop. You can either roast the chestnuts in a shallow pan. Or you can boil them, and the duration of boiling will determine the texture of the nuts. The ultimate result will be melt-in-your-mouth chestnuts.

a) Roasting Chestnuts on the Stovetop:

To roast chestnuts on the stovetop, the following steps will come in handy – 

  1. Set a shallow pan on high heat and put some oil in the pan. 
  2. Toss the scored chestnuts into the pan and stir them for 15 min. 
  3. Add 1/4 cup of water to the pan. Stir for 5 min until the water evaporates.  

b) Boiling Chestnuts on Stovetop:

It is easy to boil chestnuts on the stove. All you have to do is the following – 

  1. For a firm texture, boil the chestnuts in water for 15-20 min. 
  2. To get soft pulp, bring the water to a boil and cook the nuts for 25-30 min.    
  • Cooking Chestnuts in Air Fryer

It’s not just the traditional ways of cooking that will allow you to cook chestnuts. For example, if you have an air fryer at home, it will enable you to cook your chestnuts easily and pop them out of their shells. Doing so will allow you to cook the chestnuts without oil, just like in the traditional oven, and it will take less time.

To cook chestnuts in an air fryer, do the following:

  1. Preheat the air fryer to 400 F.
  2. Put the scored chestnuts in the basket and cook them for 10-15 min.   

So now you know that there are various ways of cooking chestnuts using the oven, air fryer, or stove. You can roast, parboil, or boil chestnuts or combine two methods. The texture will be different every time. No matter which method or medium you choose, you can choose to soak them first for 25-30 minutes. 

How Long to Store Chestnuts 

Once cooked, it’s a good idea to enjoy chestnuts the same day to experience all the freshness of the nuts. However, for the best taste, aroma, and texture, devour them while still hot. If you want to use them in other preparations, you can store your peeled chestnuts for 1-2 weeks. 

It would be best if you stored them in an air-tight container in a cool and dry place. Otherwise, they will go bad quickly. When cooked chestnuts start to go bad, they might develop a visible mold, rendering them unfit for consumption. They may also go hard, which might be fixed by soaking in water before baking or boiling. 

Why Cook Chestnuts Before Eating 

How to Cook Chestnuts in the Microwave

The general norm is to cook them first before munching on them as an autumn or winter snack. But have you ever wondered why you have to do that? You probably already know that roasting or boiling chestnuts improves the taste and texture of the nuts. Cooking also makes it easier to peel off the skin.  

Here’s why you should cook chestnuts before eating them:

  •  Taste

Raw chestnuts can taste bitter. This is because of the presence of tannic acid, which is a form of tannin. In fact, did you know that chestnuts are an essential source of vegetable tannin? This tannic acid in the paper-like skin of chestnuts gives the nuts an unpleasant taste. But it goes away when boiled or roasted.  

  •  Health

The level of tannic acid is extremely high in chestnuts. For most people, this tannin does not render chestnuts unfit for consumption. However, you have to be careful because many people also face stomach irritation and nausea when eating raw chestnuts. It can also damage the liver or kidneys.  

So don’t take the risk of getting stomach problems or other issues by eating raw chestnuts. But most people choose to eat cooked chestnuts as a snack because of the taste factor. Roasting develops a slight sweetness in chestnuts. Plus, cooking improves their texture and makes them soft like sweet potatoes. 

Popular Ways of Having Chestnuts Around the World

Your favorite snack, chestnut, comes from a deciduous tree, and if you have never seen the outer covering of the nut, you’ll be surprised. The outer shell, called the burr, is prickly and inedible. So, even though seeds of some fruits are often categorized as nuts, chestnuts are real nuts, i.e., the actual fruits. 

 It is a popular snack all over the world and is available readily in autumn and winter. Here’s how people have been enjoying chestnuts around the globe since time immemorial – 

  1. Snack: Roasted chestnuts are enjoyed as a street-side snack in Korea, China, and New York City, as well as in Portugal, where it is also eaten around a bonfire on the harvest day.  
  2. Flour: Chestnut flour is a popular ingredient used in making bread, cakes, pancakes, pasta dough, original polenta, and coat for fritters in France, especially in Corsica. 
  3. Potato Substitute: Because of its texture and high starch content, chestnuts substitute potatoes and baked potatoes in Southeast Asia and Mediterranean nations. 
  4. Thickener: Chestnut meal and pulp are popularly used as thickeners in sauces, stews, and soups in different parts of the world, especially Corsica. 
  5. Stuffing/Filling: Chestnuts are often used as a stuffing for fowl, chicken, turnkey, and vegetables, as well as filling for ravioli.
