Brussels Sprouts in the Air Fryer: Time and Temperature
Quick Answer
To cook Brussels sprouts in an air fryer:
- Temperature: 375-400°F (190-200°C)
- Time: 12-15 minutes fresh, 15-18 minutes frozen
- Shake: halfway through cooking
- Cut: halved for a crispier result
The exact time depends on the size of the sprouts and whether you leave them whole or cut them in half.

Why the Air Fryer Is Perfect for Brussels Sprouts
Brussels sprouts are one of the vegetables that improve the most when cooked in an air fryer compared to the oven or boiling:
- Crispy outer leaves: high-speed hot air browns the loose outer leaves, achieving that toasted edge that’s harder to get in the oven.
- Tender inside without overcooking: the shorter cooking time helps avoid the mushy texture and bitter taste that often comes from overboiling.
- Much faster than the oven: no need for the usual 25-30 minutes in the oven — the air fryer usually gets it done in 12-15 minutes.
- Less oil: a light drizzle is enough to get a good sear.
How to Cook Brussels Sprouts in the Air Fryer Step by Step
1. Prepare the Brussels Sprouts
Rinse the sprouts and remove any damaged or yellowing outer leaves. Trim the base with a small knife.
2. Cut Them in Half
Slice each sprout in half lengthwise. This step matters: the cut surface is what browns and crisps up, while leaving them whole gives a more even but less crispy result.
3. Season
Place the sprouts in a bowl, add a drizzle of olive oil, salt, pepper, and any seasonings you like (garlic powder, paprika). Toss well so they’re evenly coated.
4. Preheat the Air Fryer
Preheat to 400°F (200°C) for 2-3 minutes.
5. Place the Sprouts in the Basket
Arrange them cut-side down, in a single layer, without overcrowding. If you have a large amount, it’s better to cook in two batches.
6. Cook and Shake Halfway Through
Cook for 12-15 minutes, shaking the basket or flipping the sprouts halfway through so they brown evenly on both sides.
7. Check for Doneness
They should be golden and slightly crispy on the outside, and tender when pierced with a fork on the inside. If they need more time, add 2-3 extra minutes.

Cooking Time by Type
| Type | Temperature | Approximate time |
|---|---|---|
| Fresh, halved | 400°F (200°C) | 12-15 minutes |
| Fresh, whole | 375°F (190°C) | 16-20 minutes |
| Frozen | 400°F (200°C) | 15-18 minutes |
Can You Cook Frozen Brussels Sprouts Directly?
Yes, no need to thaw them first. Add them straight to the basket with a few extra minutes compared to fresh, and keep in mind they’ll release a bit more water during the first few minutes of cooking — that’s normal.
Ways to Add More Flavor to Your Brussels Sprouts
- With bacon: add small pieces of raw bacon to the basket along with the sprouts — it’ll cook at the same time and add extra flavor and fat that helps with browning.
- With balsamic glaze: drizzle a bit of reduced balsamic vinegar right before serving for a popular sweet-and-tangy contrast.
- With parmesan: sprinkle grated parmesan in the last 2-3 minutes of cooking so it melts slightly without burning.
- With honey mustard: toss with a bit of honey and mustard before cooking for a sweet-savory twist.
Common Mistakes When Cooking Brussels Sprouts in the Air Fryer
- Not cutting them in half: leaving them whole every time gives a less crispy result, since there’s less surface area in direct contact with the hot air.
- Overcrowding the basket: if they’re piled up, they steam instead of browning, turning out soft instead of crispy.
- Not shaking halfway through: increases the risk of uneven browning.
- Using very large sprouts without adjusting time: bigger sprouts need a bit more time than small ones — check for doneness before assuming they’re done if they’re on the larger side.
Frequently Asked Questions About Air Fryer Brussels Sprouts
How long do Brussels sprouts take in the air fryer?
Between 12 and 15 minutes at 400°F (200°C) if halved, or 16-20 minutes if left whole. Frozen sprouts need 15-18 minutes.
Is it better to halve them or leave them whole?
Halved sprouts turn out crispier, since the cut surface browns directly with the hot air. Whole sprouts give a more even but less crispy result.
Can you cook frozen Brussels sprouts without thawing?
Yes, you can cook them straight from frozen, adding a few extra minutes compared to fresh.
Why do my Brussels sprouts turn out bitter?
Bitterness is usually due to overcooking or sprouts that weren’t very fresh to begin with. Air frying, being a shorter cooking method than boiling, tends to give a less bitter result than other methods.
Do I need a lot of oil for air fryer Brussels sprouts?
No, a light drizzle is enough. The goal is to coat them evenly, not soak them.
Can I add bacon to the same basket?
Yes, it’s a very popular combination. Add small pieces of raw bacon along with the sprouts from the start, since they cook in similar timeframes.
How do I know when Brussels sprouts are done?
The outer leaves should be golden and slightly crispy, and they should be tender when pierced with a fork on the inside.
