Brussels sprouts, often misunderstood as a bitter and underappreciated vegetable, have transformed into a culinary delight when roasted to perfection. Their small, tightly packed leaves hold a subtle sweetness that caramelizes beautifully under heat, creating a crispy exterior while maintaining a tender, flavorful interior. Air fryers, with their rapid hot air circulation, have revolutionized the way we prepare vegetables, making them crispier, healthier, and faster than traditional roasting methods. Air frying Brussels sprouts allows you to enjoy this cruciferous vegetable at its best – golden, crispy, and bursting with nutty, savory flavor – without the need for excess oil or long cooking times. In this guide, we’ll explore every aspect of air frying Brussels sprouts, from the perfect temperature and timing to expert tips for achieving that sought-after crispiness.
Temperature is the cornerstone of perfectly air-fried Brussels sprouts. For most air fryers, the ideal temperature range falls between 375°F to 400°F (190°C to 205°C).
Cooking at too low a temperature, such as 350°F (175°C), can result in limp, underwhelming sprouts, while temperatures above 425°F (220°C) increase the risk of burning the delicate outer leaves before the interior is tender. Achieving the balance between caramelization and tenderness is key.

Timing depends on the size of the sprouts, how crispy you want them, and the temperature used. Here’s a general guideline:
It’s important to shake or stir the basket halfway through cooking. This ensures even heat distribution and prevents some sprouts from becoming overly charred while others remain undercooked. Tiny sprouts may cook faster, while halved or thicker sprouts may need an extra 2-3 minutes. Always consider your air fryer model, as some circulate air more efficiently than others.
Perfectly air-fried Brussels sprouts are golden brown on the edges with a tender interior. Indicators of doneness include:
For basic air-fried Brussels sprouts, you’ll need:
Optional flavor enhancers:
Using a temperature outside the recommended range affects both texture and cooking time:
Temperature adjustment can also be used creatively. For example, starting at a lower temperature to soften the sprouts, then finishing at high heat for extra crispiness, is an effective strategy.
Cooking time is tied to temperature, sprout size, and personal preference:
Always check the sprouts visually and taste-test a piece if unsure – air fryers vary widely in efficiency.
Even experienced cooks face hiccups:
Mistakes can often be corrected mid-cook. For example, removing over-browned leaves or lowering the temperature can salvage the batch.
Start by trimming the ends of the Brussels sprouts and removing any yellow or damaged outer leaves. Then, cut them in half to ensure even cooking. Toss the halved sprouts with a small amount of olive oil, salt, pepper, and optional seasonings like garlic powder, paprika, or balsamic vinegar before placing them in the air fryer basket.
For optimal results, preheat your air fryer to 375°F (190°C). This temperature allows the Brussels sprouts to cook evenly, develop a golden-brown exterior, and retain a slightly tender interior. Cooking at a lower temperature may result in softer sprouts, while higher temperatures risk burning the outer leaves.
Cook Brussels sprouts in the air fryer for 15-20 minutes, shaking or stirring the basket halfway through the cooking process. The exact time may vary depending on the size of the sprouts and the air fryer model. Smaller sprouts may cook faster, while larger ones may require an additional 2-3 minutes.
While it is not strictly necessary to use oil, a light coating of oil helps enhance browning and crispiness. You can use olive oil, avocado oil, or any oil with a high smoke point. For an oil-free option, consider spraying a thin layer of water or using a non-stick cooking spray, though the sprouts may be less crispy.
Yes, seasoning is recommended to enhance flavor. Common seasonings include salt, pepper, garlic powder, paprika, or chili flakes. You can also add a drizzle of balsamic vinegar or a sprinkle of Parmesan cheese after cooking for extra flavor. Toss the Brussels sprouts evenly to ensure each piece is coated with seasoning.
To achieve extra crispy Brussels sprouts, ensure they are cut evenly and not overcrowded in the air fryer basket. Shake the basket halfway through cooking to promote even crisping. Using a light coating of oil and cooking at a slightly higher temperature (around 400°F or 200°C) for the last 2-3 minutes can also help create a golden, crunchy exterior.
Yes, leftovers can be reheated in the air fryer to restore crispiness. Preheat the air fryer to 350°F (175°C) and cook the Brussels sprouts for 3-5 minutes, shaking halfway through. Avoid reheating in the microwave if you want to maintain their crisp texture, as microwaving tends to make them soggy.
