Brussels sprouts are a great vegetable to cook in an air fryer. The air fryer's super-hot circulating air makes the sprouts tender on the inside while the outside turns crispy. Air-fried Brussels sprouts are healthier than deep-fried sprouts, and they are also easier to prepare. You can season them with a variety of sweet and savoury flavours, such as honey, balsamic vinegar, or parmesan. The cooking time is also shorter than other methods, and you can have delicious sprouts ready in under 20 minutes.

How to get the perfect crunch

To get the perfect crunch when cooking Brussels sprouts in an air fryer, there are several steps you can take. Firstly, ensure your sprouts are all of a similar size. This will help them cook evenly, so some don't burn while others are only slightly crispy. You can do this by halving or quartering them. If you want them softer in the centre, soak the sprouts in water for 10 minutes before cooking.

Secondly, toss the sprouts with a high-quality oil. Avocado oil is recommended, but olive oil will also work well. You can also add other seasonings at this stage, such as salt, pepper, garlic, or garlic powder. You want to ensure each sprout is coated evenly, so don't be afraid to use a little more oil if needed.

Thirdly, arrange the sprouts in a single layer in the air fryer basket. This will allow the hot air to circulate and ensure even cooking and crisping. Set the temperature to 375°F (190°C) and cook for 10-12 minutes, shaking the basket halfway through. If you want them darker and crispier, you can cook them for a further 2-4 minutes.

Finally, you can finish your sprouts with a variety of toppings. A buttery glaze or balsamic glaze will add a classic touch, while a drizzle of honey and your favourite hot spice will give them a spicy kick. If you want to add a cheesy twist, sprinkle some Parmesan over the sprouts during the last few minutes of cooking.

Oil types and how much to use

Oil is an essential component when cooking Brussels sprouts in an air fryer, as it helps to achieve the desired crispy texture. While it is possible to cook Brussels sprouts in an air fryer without oil, the addition of oil improves the texture and overall taste. The amount of oil used can vary depending on personal preference and the desired level of crispness. However, it is important to note that air frying already requires significantly less oil than traditional oven cooking.

When selecting an oil type, it is recommended to choose a neutral-flavoured oil, such as avocado oil or olive oil. Avocado oil is known for its ability to enhance crispness and is a favourite among cooks. If you don't have avocado oil, olive oil can be used as a substitute or as the primary oil choice. Additionally, grape seed oil is another option for a neutral-flavoured oil that can help achieve the desired crispness.

To ensure even cooking and browning, it is crucial to coat each sprout evenly with oil. This can be done by tossing the sprouts with oil in a bowl before placing them in the air fryer. If needed, don't be afraid to use a little extra oil to achieve the desired level of crispness.

For those who prefer a completely oil-free option, there is a simple tweak. Instead of using oil, you can substitute it with maple syrup, which will give your Brussels sprouts a tender inside and a crispy outside.

Soaking and seasoning

Soaking the Brussels sprouts in water for about 10 minutes is a good way to ensure they are cooked through and tender. It also helps to lessen some of the bitterness and slow down the speed at which the sprouts brown, reducing the risk of burning. It is important to dry them thoroughly after soaking to promote ideal crispiness.

When it comes to seasoning, a simple combination of olive oil, salt, and black pepper can be used. For added depth, garlic powder, slivers of garlic, or minced shallots can be added—they caramelize beautifully, bringing savoury notes. To spice things up, add red pepper flakes, crushed red pepper, or smoked paprika.

For a sweet and tangy twist, drizzle balsamic vinegar, pomegranate molasses, honey, or maple syrup. For a savoury touch, finish with grated Parmesan cheese or lemon zest.

Cooking time and temperature

The ideal temperature for cooking Brussels sprouts in an air fryer is around 375°F (190°C). Not all air fryers require preheating, but for the crispiest sprouts, it is best to start with a hot air fryer.

Brussels sprouts should be cooked for 10-15 minutes, depending on the desired texture. For sprouts that are crispy on the outside and tender on the inside, it is recommended to soak the sprouts in water for 10 minutes before cooking. This softens them, so they require less time in the air fryer. Sprouts that are not soaked can be cooked for 10-12 minutes, while those that have been soaked should only be cooked for 5-8 minutes. It is important to shake the basket several times throughout cooking to keep the air circulating and ensure even cooking.

Cooking times can vary depending on the type of air fryer, the size of the sprouts, and personal preference for texture. For sprouts that are crispy on the outside and tender on the inside, it is important to keep a close eye on them to avoid overcooking. If the sprouts are still tough after air frying, the temperature may be too high, as all brands cook differently.

To add flavor, sprouts can be tossed with olive oil, salt, pepper, and garlic before or after cooking. For a buttery glaze, sprouts can be finished with a drizzle of honey and a sprinkle of cayenne pepper or red pepper flakes.

Avoiding sogginess

To avoid sogginess, it is important to ensure that the Brussels sprouts are not overcrowded in the air fryer basket, as this will prevent proper air circulation and lead to uneven cooking. It is recommended to arrange the sprouts in a single layer, which may require cooking in batches.

Another key factor is the cooking temperature. A temperature of 375°F (190°C) is generally recommended for air frying Brussels sprouts, as it allows them to cook through without burning. It is important to preheat the air fryer to this temperature before adding the sprouts.

To achieve the desired tenderness without sogginess, it is suggested to soak the Brussels sprouts in water for about 10 minutes before cooking. This technique softens their centers, ensuring they are tender while also preventing sogginess. After soaking, it is crucial to dry the sprouts thoroughly before placing them in the air fryer.

Additionally, trimming the ends of the sprouts and halving or quartering larger ones is essential. This helps to promote even cooking and a consistent texture. It is also recommended to remove any discolored or wilted outer leaves to ensure the best flavor and texture.

Finally, shaking the air fryer basket several times throughout the cooking process is crucial. This keeps the air circulating and ensures that the sprouts crisp evenly. Depending on the desired level of crispiness, the cooking time can be adjusted, typically ranging from 10 to 15 minutes at the recommended temperature.
