How to get the perfect crunch

To get the perfect crunch on your roast potatoes, there are several methods you can try. Firstly, it is important to note that the type of potato you use can affect the crispiness of your roast potatoes. Starchier potatoes, such as russets or Yukon golds, tend to crisp up more easily due to their floury, low-moisture interior.

Pre-cooking methods

One method to achieve crispiness is to soak the potatoes in an alkaline solution of baking soda and water before cooking. This helps break down the outer layer of the potatoes, creating a starchy slurry that coats the potatoes. As they cook, this slurry will help the exterior develop a crunchy, craggy crust. Alternatively, you can simply soak starchy potatoes in cold water for 10-15 minutes to remove excess starch, which can cause the potatoes to brown too quickly.

Oil

Using oil is essential to achieving the perfect crunch. Make sure to pat the potatoes dry after rinsing or soaking, then add them to a large bowl and toss them with oil. You can use extra virgin olive oil or another oil of your choice. Ensure the potatoes are well-coated by shaking or stirring the bowl.

Seasoning

While not necessary, seasoning your potatoes can add flavour and enhance their crispiness. You can season with salt and pepper, smoked paprika, garlic powder or granules, Italian seasoning, or other herbs such as thyme or rosemary.

Air fryer settings

Place the potatoes in the air fryer basket in a single layer to ensure maximum crispiness. If you are using a tray insert, a shallow tray is best. Set the air fryer to cook at 190°C to 200°C for 20 to 30 minutes. For even cooking and browning, shake the air fryer basket or turn the potatoes every 5 to 10 minutes. If your air fryer has a paddle, you can use it to ruffle the edges of the potatoes slightly.

Post-cooking methods

If your potatoes are not crispy enough, you can try bashing them with the back of a spoon to ruffle the edges. You can also cook them for an additional few minutes until they reach the desired level of crispiness.

With these methods, you can achieve the perfect crunch on your roast potatoes, every time!

The best potatoes for roasting

When it comes to choosing the best potatoes for roasting in an air fryer, there are a few factors to consider. The type of potato, the preparation method, and the desired level of crispiness can all impact the final result.

Firstly, it is essential to select the right type of potato. In the UK, the best options are considered to be Maris Piper, King Edward, and Rooster potatoes. These varieties are known for their fluffy texture and ability to achieve a crispy exterior when roasted. If you're in the US, Yukon Gold potatoes are an excellent choice and are widely available. Red potatoes and russet potatoes are also good options, and some people recommend using new potatoes for a tastier result.

The preparation method for roasting potatoes in an air fryer can vary depending on your preferences. Some people choose to peel their potatoes, while others leave the skin on for a crispier texture. It is generally recommended to cut the potatoes into bite-sized chunks, approximately 3-6 cm in size, to ensure even cooking. Soaking starchy potatoes in cold water for 10-15 minutes before roasting can also help reduce excess starch and improve the crispness.

To achieve the desired level of crispiness, there are a few techniques to consider. Some people recommend parboiling the potatoes before roasting them in the air fryer, as it helps create a deliciously crispy crust. Others suggest simply coating the potatoes in oil, with options such as olive oil, duck fat, or sunflower oil, and seasoning them with salt, pepper, garlic powder, onion powder, or various herbs before placing them directly in the air fryer. Cooking the potatoes in a single layer can also maximise crispiness.

In summary, the best potatoes for roasting in an air fryer are those that will result in a soft, fluffy interior and a crispy exterior. Maris Piper, King Edward, Rooster, and Yukon Gold potatoes are excellent choices, but ultimately, any potato can be used with the right preparation and cooking techniques. Experimenting with different varieties, preparation methods, and seasonings can help you find the perfect roasted potatoes that suit your taste and preferences.

Oil and seasoning

When it comes to oil, extra virgin olive oil is a good choice for roasting potatoes in an air fryer. You can also use regular olive oil, which is healthier than vegetable or canola oil. The amount of oil used is significantly less than traditional roasting methods, but it is still important to ensure that the potatoes are well-coated.

To coat the potatoes, place them in a large bowl and toss them with the oil. You can also add seasonings to this bowl, such as garlic powder, granules or fresh garlic, smoked paprika, Italian seasoning, Cajun seasoning, or simply salt and pepper. You could also try infusing the oil with aromatics such as rosemary or thyme to add extra flavour. If you want to add a squeeze of lemon, it is best to do this just before serving to avoid the potatoes becoming soggy.

After coating the potatoes in oil and seasonings, place them in the air fryer basket or a shallow tray insert and cook according to your recipe. If you are cooking for a longer period or aiming for extra crispy potatoes, you can also add another drizzle of oil partway through the cooking process.

Should you parboil the potatoes first?

Parboiling is an optional step when making roast potatoes in an air fryer. Some recipes recommend parboiling the potatoes before air frying, while others suggest simply cutting, seasoning, and air frying.

Parboiling potatoes before air frying can result in a fluffier interior and crispier crust. Parboiling potatoes in a solution of water and baking soda can help break down the outer layer, creating a starchy slurry that gives the potatoes an extra crunch. This slurry coats the potatoes when they are tossed in a bowl with oil. As the potatoes air fry, the slurry helps the exterior develop a crunchy, craggy crust.

However, parboiling is not necessary to achieve crispy roast potatoes in an air fryer. Air fryers can produce crispy potatoes without the need for parboiling, using significantly less oil than traditional roasting methods. The high temperature of the air fryer can create an ultra-crispy, golden exterior, while the inside remains soft and fluffy.

Whether or not you choose to parboil your potatoes, it is important to dry them thoroughly before adding oil and seasoning. This will help ensure that your potatoes come out crispy and golden.

How long to cook for

The cooking time for roast potatoes in an air fryer varies depending on the recipe and the size of the potatoes. On average, it takes 20 minutes to cook roast potatoes in an air fryer. However, some recipes suggest cooking for 10 minutes, flipping the potatoes, and then cooking for another 10 minutes.

For example, one recipe recommends peeling and chopping the potatoes into bite-sized chunks (about 3-3.5 cm or 1+1/4 to 1+1/3 inches). After rinsing and drying the potatoes, place a shallow tray insert into the air fryer basket, add the potatoes, and drizzle with oil. Shake to coat the potatoes evenly. Cook for 5 minutes at 200°C/400°F, then turn or shake the potatoes and cook for another 5 minutes. Turn or shake the potatoes again, bashing them slightly with the back of a spoon to ruffle the edges. Drizzle with another tablespoon of oil and cook for a final 10 minutes. This recipe suggests cooking the potatoes for a total of 20 minutes until they are crisp and golden.

Another recipe recommends a cooking time of 30 minutes at 190°C, followed by an additional 5-10 minutes if the potatoes are not yet tender or brown enough. This recipe suggests cutting the potatoes into evenly sized pieces, steaming or simmering them for 5 minutes, and then draining and coating them with oil before placing them in the air fryer.

It is worth noting that some recipes suggest parboiling the potatoes before placing them in the air fryer to achieve a crispier texture. However, this is not necessary, and roast potatoes can be cooked directly in the air fryer for a quicker and easier option.

Additionally, the type of potato used can affect the cooking time. Starchier potatoes, such as russets or Idaho potatoes, and Yukon Golds, tend to crisp up more easily and develop fluffy insides. On the other hand, waxy varieties like new potatoes or fingerlings are not ideal for roasting.
