How Long to Air Fry Brussels Sprouts for Perfect Crispiness Every Time

How Long Should You Air Fry Brussels Sprouts?

Brussels sprouts are a beloved vegetable known for their rich nutritional profile and unique taste. When prepared properly, they can be crispy, tender, and full of flavor. Air frying Brussels sprouts has gained immense popularity due to its ability to cook the vegetable quickly while retaining its crunch and minimizing the use of oil. But the question remains: How long should you air fry Brussels sprouts? Let’s explore the perfect air frying technique and timing to ensure your Brussels sprouts turn out just right every time.

Why Brussels Sprouts?

Brussels sprouts are a nutritious vegetable that belong to the cruciferous family, which also includes broccoli, kale, and cabbage. These mini cabbages are packed with fiber, vitamins, and antioxidants, making them an excellent addition to any healthy diet. Air frying Brussels sprouts can enhance their flavor without sacrificing their health benefits, as this cooking method requires little to no oil.

Additionally, air frying Brussels sprouts is considered one of the healthiest ways to prepare them. Unlike deep-frying, which adds excessive fats, air frying uses hot air to achieve that crispy exterior without overloading your dish with oil. It’s also a faster cooking method compared to oven roasting, allowing you to enjoy your veggies in less time.

What is the Right Temperature for Air Frying Brussels Sprouts?

When it comes to air frying Brussels sprouts, temperature plays a crucial role in achieving the perfect texture. The general recommendation is to air fry at 375°F to 400°F (190°C to 200°C) for best results. Cooking at this temperature ensures that your Brussels sprouts get that golden-brown, crispy exterior while remaining soft and tender inside.

The right air fryer temperature is key to ensuring the Brussels sprouts don’t dry out or burn. Air fryers vary by brand, but most of them will perform well within this temperature range. If you like your Brussels sprouts extra crispy, you can increase the temperature slightly or extend the cooking time, but be mindful to avoid burning.

It’s important to preheat your air fryer before you start cooking to ensure consistent results.

How Long Should You Air Fry Brussels Sprouts?

The key to crispy Brussels sprouts lies not just in the temperature but also in the timing. In general, you should air fry Brussels sprouts for 15–20 minutes, depending on their size and your desired level of crispiness.

Here’s a breakdown of factors that can affect cooking time:

  • Size of the Brussels sprouts: Larger Brussels sprouts will take longer to cook than smaller ones. If your Brussels sprouts are large, you may want to slice them in half or quarters to ensure even cooking.
  • Air fryer model: Different air fryers can have slightly different heat distributions. Some might require less time, while others might need a bit more.
  • Desired crispiness: If you prefer your Brussels sprouts with a crispy exterior, you may need to extend the cooking time slightly. Just remember to shake or toss the sprouts halfway through to ensure even browning.

Preparing Brussels Sprouts for Air Frying

Proper preparation is key to getting the best results when air frying Brussels sprouts. Here’s a step-by-step guide on how to prep them:

  • Trim the Brussels sprouts: Start by cutting off the hard, woody stem at the bottom of each sprout. Then, remove any discolored or wilted leaves.
  • Cut them for even cooking: To ensure even cooking, it’s a good idea to cut the Brussels sprouts in half or quarters, especially if they’re on the larger side. This helps them cook more quickly and evenly.
  • Season them: Lightly coat your Brussels sprouts with olive oil or another cooking oil. Season with salt, pepper, and any other seasonings you prefer. Popular seasoning options include garlic powder, onion powder, smoked paprika, or balsamic vinegar.
  • Optional: For extra flavor, you can marinate your Brussels sprouts before air frying them. This can be done with a simple vinaigrette or a soy sauce-based marinade.

Some people recommend using parchment paper or an air fryer basket liner to avoid sticking. However, this isn’t necessary as long as your Brussels sprouts are properly coated with oil.

Air Frying Brussels Sprouts: Step-by-Step Process

Follow these steps to get perfectly cooked Brussels sprouts in the air fryer:

  1. Preheat your air fryer: Before cooking, preheat your air fryer to 375°F (190°C). This ensures the hot air circulates effectively and crisps up the Brussels sprouts.
  2. Place the Brussels sprouts in the air fryer basket: Arrange the Brussels sprouts in a single layer in the basket. Avoid overcrowding them, as this can lead to uneven cooking.
  3. Cook for 15–20 minutes: Air fry the Brussels sprouts for 15–20 minutes, depending on their size and how crispy you want them. Shake the basket halfway through the cooking time to ensure even browning.
  4. Check for doneness: After the cooking time is up, check the Brussels sprouts. They should be golden brown with crispy edges. If they’re not as crispy as you’d like, you can air fry them for an additional 3–5 minutes.

Air frying Brussels sprouts is a quick and easy process that gives you crispy results in under 30 minutes.

Common Mistakes to Avoid While Air Frying Brussels Sprouts

While air frying Brussels sprouts is easy, there are some common mistakes that can prevent you from achieving the best results. Avoid these pitfalls:

  • Overcrowding the basket: It’s important not to overcrowd the Brussels sprouts in the air fryer basket. Overcrowding can result in uneven cooking and prevent them from getting crispy.
  • Not shaking the basket: Shaking or stirring the Brussels sprouts halfway through the cooking time is essential for even browning.
  • Overcooking or undercooking: Keep an eye on your Brussels sprouts. If you leave them in too long, they can become dry and burnt. If they’re undercooked, they won’t have the desired crispiness.
  • Using too much oil: While a light coating of oil helps the Brussels sprouts crisp up, using too much oil can make them soggy.

Variations: Flavoring Brussels Sprouts

Brussels sprouts are incredibly versatile and can be seasoned in various ways. Here are a few flavor combinations to try in your air fryer:

  • Balsamic glaze: After air frying, drizzle balsamic vinegar and a touch of honey for a sweet-and-sour finish.
  • Garlic and parmesan: Toss your cooked Brussels sprouts in grated parmesan cheese and minced garlic for a savory option.
  • Spicy: Add a pinch of cayenne pepper or chili flakes for some heat. You can even toss in a dash of hot sauce before air frying.
  • Maple syrup: For a sweet flavor, drizzle a little maple syrup over your Brussels sprouts during the last few minutes of cooking.

You can also pair Brussels sprouts with other vegetables or proteins in the air fryer, such as bacon, mushrooms, or even chicken breast.

FAQs about Air Frying Brussels Sprouts

How do you know when Brussels sprouts are done in an air fryer?

Brussels sprouts are done when they’re golden brown and crispy on the outside while still being tender on the inside. A quick way to check is to cut one in half. If the inside is soft and the outer layer is crispy, they are ready to eat. The crispy exterior is a sign that the high heat of the air fryer has worked its magic, caramelizing the sprouts and making them flavorful. If you prefer them extra crispy, you can increase the cooking time by a couple of minutes, but be cautious not to overcook them.

Can you air fry frozen Brussels sprouts?

Yes, frozen Brussels sprouts can absolutely be air-fried! The process is similar to fresh ones, although the cooking time may need to be adjusted. Frozen Brussels sprouts tend to release moisture as they cook, so you may want to cook them at a slightly lower temperature to allow the moisture to evaporate and crisp up. To ensure they’re flavorful, add a bit more seasoning and oil, as the freezing process can sometimes dull the taste of the sprouts.

Do you need to preheat the air fryer for Brussels sprouts?

Preheating your air fryer is highly recommended. It ensures that the Brussels sprouts cook evenly and start crisping right away. Preheating helps the air fryer maintain a consistent temperature, which is essential for achieving that perfect crispy exterior. If you skip this step, you may find that the sprouts cook unevenly or don’t crisp up as well as you’d like.

Can you make Brussels sprouts crispy without oil?

While oil definitely helps achieve the crispy texture we love, it is possible to make Brussels sprouts crispy without it. Simply use a small amount of cooking spray or opt for a non-stick air fryer basket to reduce the need for extra fats. For those on a low-fat diet, this method works well while still ensuring that your Brussels sprouts don’t become soggy.

How do you keep Brussels sprouts from getting soggy?

To avoid soggy Brussels sprouts, it’s important to avoid overcrowding the air fryer basket. When the sprouts are packed too tightly, they don’t have enough room for the hot air to circulate around them, which leads to uneven cooking. Make sure to coat your Brussels sprouts lightly with oil or spray them with cooking spray to help with crisping. Additionally, shaking the basket halfway through cooking ensures even air circulation, which is key to preventing sogginess.

What are some good seasoning ideas for air frying Brussels sprouts?

When it comes to seasoning, the options are endless! You can keep it simple with salt and pepper or get creative with a variety of flavors:

  • Garlic and onion powder for a savory taste
  • Smoked paprika for a smoky kick
  • Balsamic vinegar for a tangy, sweet glaze
  • Parmesan cheese for a rich, umami finish
  • Honey or maple syrup for a sweet touch that contrasts beautifully with the Brussels sprouts’ natural bitterness
  • Chili flakes or cayenne pepper for a spicy kick

Feel free to experiment with different combinations based on your preferences, and don’t forget to toss the Brussels sprouts well to ensure they’re evenly coated with the seasoning.


By following the steps and tips outlined above, you’ll consistently achieve perfectly crispy Brussels sprouts every time you use your air fryer. Whether you like them savory with garlic and parmesan, sweet with a drizzle of honey, or spicy with a dash of cayenne pepper, air frying gives you the flexibility to customize your flavors. The best part? It’s a quick and healthy cooking method that ensures the Brussels sprouts remain tender on the inside while getting that delicious, crispy exterior. Unlike traditional frying, air frying doesn’t require excessive amounts of oil, making it a healthier alternative without sacrificing flavor or texture.
