What You'll Learn
Choosing the right chestnuts
Check for Quality and Freshness:
Look for chestnuts that are of high quality and fresh. Choose those that are smooth, plump, and shiny. Avoid chestnuts with blemishes, small holes, or signs of rot. Give them a gentle squeeze to ensure they are firm. If the shell makes a crunch sound, they may be past their prime.
Size and Uniformity:
Try to select chestnuts that are of similar size. This will ensure that they cook evenly in the air fryer. Uniformly sized chestnuts will help you avoid a situation where some are overcooked while others are undercooked.
Skin Condition:
Examine the skin of the chestnuts. It should not be dry. A moist and supple skin is a good indicator of freshness.
Avoid Confusion:
Be careful not to confuse regular chestnuts with horse chestnuts (also called buckeyes) or water chestnuts. Horse chestnuts are toxic and not meant for consumption. Water chestnuts will also drastically change the taste and texture of your recipe.
Storage and Preparation:
Store uncooked chestnuts in the refrigerator. They are best used within 1-3 weeks of purchase for optimal freshness and taste. Before cooking, rinse the chestnuts under cold running water and then pat them dry.
By following these tips, you'll be well on your way to choosing the right chestnuts for your air fryer recipe. Remember to inspect each chestnut carefully and trust your senses to select the freshest and most suitable ones for cooking.

Preparing the chestnuts for cooking
Preparing chestnuts for cooking in an air fryer requires a few steps, but it's a quick and easy process overall. Here is a detailed guide:
Firstly, choose the right chestnuts. Opt for sweet chestnuts (Castanea sativa) with super spiky casings, rather than horse chestnuts (Aesculus hippocastanum), which are toxic and not edible. Look for heavy, smooth, and glossy chestnuts without blemishes or mould. Ensure the skin isn't dry, and avoid those with little holes as they may be rotten or infested.
Once you have the right chestnuts, start by rinsing them under cold running water in a colander. Drain them thoroughly. Place the chestnuts on a cutting board, ensuring the flat side is down and the rounded side is facing up. Using a sharp paring knife or chestnut knife, carefully cut horizontally across the rounded side, making a large "X" on the top. Be careful not to cut into the inner skin. This scoring step is crucial as it allows steam to escape during cooking, preventing explosions and making the chestnuts easier to peel.
After scoring, transfer the chestnuts to a bowl and cover them with cold or warm tap water. Let them soak for 10 to 15 minutes, or even up to 30-60 minutes if you prefer. Soaking helps to release the steam and makes peeling easier.
Once soaked, remove the chestnuts from the water and pat them dry with a kitchen towel or paper towel. Your chestnuts are now ready to be placed into the air fryer and cooked according to your preferred recipe!

Firstly, select the right chestnuts. Choose smooth, plump, and shiny chestnuts, avoiding any with blemishes or mould. Ensure they are heavy and free from little holes, as these may indicate the presence of rot or insects. It is important to note that horse chestnuts, or conkers, are not edible and can cause stomach aches, so be sure to forage or purchase sweet chestnuts.
Before cooking, prepare the chestnuts by rinsing them under cold running water and draining them. Place the chestnuts on a cutting board, ensuring the flat side is down and the rounded side is facing up. Using a sharp knife, carefully cut a large "X" on the top of each chestnut, ensuring you do not cut into the inner skin. This scoring allows steam to escape during cooking, preventing explosions and making the chestnuts easier to peel.
Next, preheat your air fryer to between 375-400 degrees Fahrenheit (190-204 degrees Celsius). While the air fryer is preheating, soak the chestnuts in warm to hot water for 10-15 minutes. This step helps to release the skins and makes the chestnuts easier to peel. After soaking, pat the chestnuts dry with a towel.
Now, you are ready to cook the horse chestnuts. Place the chestnuts in the air fryer basket with the scored "X" facing upright. Set the timer for 8 to 12 minutes, depending on the size of the chestnuts. Smaller chestnuts may only need 4 to 6 minutes, while larger ones might require up to 15 minutes or more. Keep a close eye on them to ensure they do not burn or burst.
Once the chestnuts are roasted, remove them from the air fryer and place them in a bowl. Allow them to cool completely, and you will hear a satisfying crackle as they do so. Finally, use your fingers to peel away the shell and skin. If the chestnuts are too hot to handle, you can use kitchen gloves or a tea towel to assist in the peeling process.

Cooking time
The cooking time for horse chestnuts in an air fryer depends on several factors, including the size of the chestnuts, the temperature of the air fryer, and the desired level of doneness. Here is a step-by-step guide to help you determine the ideal cooking time:
Preparing the Chestnuts:
First, select fresh, high-quality chestnuts that are smooth, plump, and shiny, avoiding any with blemishes or mould. Ensure you are using edible sweet chestnuts (Castanea sativa) and not horse chestnuts (Aesculus hippocastanum), which are toxic and not suitable for consumption.
Soaking the Chestnuts:
Some recipes recommend soaking the chestnuts in warm or hot water before air frying. This step is optional, but it can help make the chestnuts easier to peel. If you choose to soak them, place the chestnuts in a bowl and cover them with warm or hot water for 10 to 15 minutes. You can also add a scoring (making an "X" cut) on the rounded side of each chestnut before soaking to further aid in the peeling process.
Preheating the Air Fryer:
Preheat your air fryer to the desired temperature. Different recipes suggest varying temperatures, ranging from 375°F (190°C) to 400°F (204°C). Choose a temperature setting that aligns with your preferred doneness and cooking time.
Air Frying the Chestnuts:
Place the prepared chestnuts in the air fryer basket, ensuring that the scored side (the "X") is facing up. This positioning will allow for even cooking and easier peeling. Set the timer for the initial cooking period, which can range from 5 to 10 minutes for smaller chestnuts and up to 15 minutes or more for larger ones. Keep a close eye on them to avoid burning or bursting.
Checking for Doneness:
After the initial cooking time, carefully open the air fryer and inspect the chestnuts. Look for signs of the shells peeling back and exposed flesh browning. If the chestnuts are not done to your liking, return them to the air fryer in 1-minute intervals until they reach your desired level of doneness.
Cooling and Peeling:
Once the chestnuts are cooked to your preference, remove them from the air fryer and allow them to cool. You will hear them crackle as they cool, indicating that the shells are loosening. When they are cool enough to handle, use your fingers or a kitchen towel to peel away the shells and enjoy your freshly cooked horse chestnuts!

Peeling the chestnuts
Once you have the right chestnuts, it's time to start preparing them for peeling. Use a sharp knife, preferably a small serrated paring knife, to cut a slit or a cross on the top of each chestnut. This process is called scoring and helps to release steam during cooking, preventing the chestnuts from exploding. It also makes the peeling process easier after cooking. Place the chestnuts flat-side down on a cutting board and hold them firmly while scoring. Be careful not to cut through the inner skin of the chestnut.
After scoring, some recipes recommend soaking the chestnuts in hot water for 10 to 15 minutes. This step is optional, as some people find that it doesn't make a difference in the peeling process. However, if you do choose to soak them, pat the chestnuts dry with a towel before placing them in the air fryer.
Now, you're ready to air fry the chestnuts. Preheat your air fryer to between 375 to 400 degrees Fahrenheit (190 to 204 degrees Celsius). Place the scored chestnuts in the air fryer basket with the scored side facing up. This will allow the shell to peel back without sticking to the tray. Air fry for 8 to 12 minutes, depending on the size of the chestnuts. Smaller chestnuts will take less time, around 5 to 6 minutes, while larger ones may need up to 15 minutes or more. Keep an eye on them to ensure they don't burn or burst.
Once the chestnuts are done, remove them from the air fryer and place them in a bowl. Cover the bowl to trap the steam, which will help with the peeling process. Let the chestnuts cool slightly, but peel them while they are still warm, as they will be easier to peel at this stage. Use your fingers to peel off the shell and skin. If they are too hot to handle, you can use kitchen gloves or a tea towel to assist.
