Yet another reason to love the air fryer: air-fried Brussels sprouts. Super crispy on the outside and tender but not mushy on the inside, they are similar to roasted Brussels sprouts at their best. And the ingredient list? Brussels sprouts, olive oil, salt, and pepper. Plus Parmesan and the optional addition of lemon zest — that’s it!

The advantages of using the air-fryer are speed (just 15 minutes!) and not having to preheat the oven. This amazing little kitchen appliance is perfect for green beans, baked potatoes, salmon, and even bacon! And during holiday dinners (or any time when oven real estate is in high demand), being able to get a dish cooked without the oven or stove, and in a hands-free way, is a big plus. That leaves you more room in your oven for roasting a turkey or browning the marshmallows on your sweet potato casserole.

Air Fryer Brussels Sprouts Ingredients

The air fryer Brussels sprouts recipe relies on a few common ingredients.

Fresh Brussels sprouts, cheese, and lemon on marble surface.
  • Brussels sprouts – Try to pick Brussels sprouts with a consistent size. If your Brussels sprouts are very small, you might leave them whole; otherwise, cut them in half.
  • Olive oil – Helps the sprouts get beautifully brown and crispy on the edges as they cook.
  • Salt and pepper – You may want to season with additional salt and pepper at the end as well.
  • Parmesan – Sprinkle the Parmesan over the Brussels sprouts while they are still hot so that the cheese melts into them.
  • Lemon zest – Another optional add-in that adds a nice spark to the dish.

How to Cook Brussels Sprouts in the Air Fryer

  1. Prepare the Brussels sprouts: Trim and halve the Brussels sprouts. Place them in a large bowl, add the olive oil, salt, and pepper, and toss to coat.

  1. Cook: Set the air fryer to 375 degrees. Transfer the sprouts to the air fryer in a single layer (you can crowd them a bit more than you see in the photos; they will still crisp up nicely). Cook, shaking or tossing halfway through, until well-browned and crispy on the outside, tender on the inside, about 15 minutes.

Tips

  • As soon as the Brussels sprouts are cooked, you will want to transfer them to a bowl, and while hot, sprinkle over the Parmesan and toss. The heat from the vegetables allows the cheese to melt a bit and coats the Brussels sprouts nicely.
  • Try to keep the Brussels sprouts in a single layer, but they can be touching. This way, they will caramelize on the outside while cooking.
  • Shake the Brussels sprouts in the air fryer basket or tray midway through baking to ensure even cooking and browning.
  • Use finely grated Parmesan so it melts easily into the warm Brussels sprouts.

FAQs

How long do you cook Brussels sprouts in the air fryer?

Cooking time will vary depending on the size of the Brussels, and luckily, you can open the air fryer, test one of the Brussels, and keep going if you want them cooked further. I would say about 15 minutes at 375 degrees is perfect for medium-sized Brussels sprouts. Remember that they will continue to soften a bit after they come out of the air fryer, so stop the cooking just as you get to the level of tenderness that you like.

Why aren’t my Brussels sprouts crispy?

Your Brussels sprouts may not be crispy because of the temperature you’re cooking at, or because of the cooking method. In the oven, I roast Brussels sprouts at 400 degrees for 30 to 35 minutes. This ensures the sprouts are tender on the inside and brown and crispy on the outside.

For an even crispier result, I like to cook them in an air fryer. The air circulation guarantees crispiness in even less time: I air fry them at 375 degrees for 15 minutes. Make sure they are in a single layer, and shake them midway through the cooking time to ensure crispiness. The crispiest Brussels sprout possible is probably deep-fried, but this is way too much of a hassle to do at home, so the air fryer is your best bet.

Can you cook Brussels sprouts in the air fryer?

Yes, you can cook Brussels sprouts in the air fryer! It is actually one of the best ways to cook them. When compared to oven roasting, air frying is quicker and results in crispier Brussels sprouts. Just season and coat the sprouts with oil, and spread them out in a single layer in your air fryer. Fifteen minutes later, you will have beautifully crispy and tender Brussels sprouts ready to go!
