Process
Timers built in · swap anything · ask as you cook
Trim the stem end of the 500 g Brussels sprouts just enough to remove any dry nub, then cut each one in half lengthwise straight through the stem so the halves stay attached.
Peel away any loose or yellowed outer leaves and discard them, but leave the tight inner leaves intact.
Pat the halved sprouts completely dry with a clean kitchen towel or paper towels; surface moisture is the main cause of steaming instead of crisping.
In a large bowl, toss the dry sprouts with 2 tbsp olive oil, 1 tsp garlic powder, 0.5 tsp smoked paprika, 0.75 tsp fine salt and 0.25 tsp black pepper until every piece is evenly coated.
Preheat the air fryer at 195°C for 3 minutes.
Arrange the sprouts in the air fryer basket in a single layer with the cut sides facing down, working in two batches if needed so the basket is not crowded.
Air fry at 195°C for 12 to 15 minutes, shaking the basket once at the halfway point, until the cut sides are deep golden brown and the loose leaves are dark and crisp.
Transfer to a serving dish, squeeze the juice of half a lemon over the top if using, and finish with a pinch of flaky sea salt. Serve immediately.
Kitchen notes
Kitchen notes
- The single biggest mistake is crowding the basket: piled-up sprouts release steam and turn soft and grey instead of crisp. Fry in two batches if your air fryer basket is smaller than about 20 cm across.
- Dry the sprouts thoroughly after washing. Any water left on the surface steams the sprouts and prevents the Maillard browning that gives the crisp edges.
- Cut-side-down placement matters: the flat cut face makes direct contact with the hot basket and browns first, giving the best texture contrast against the tender interior.
- Air fryers vary in power. Start checking at 11 minutes; the sprouts are done when a knife slides into the core with no resistance and the outer leaves are brittle and dark at the edges.
Substitutions
- smoked paprika→sweet paprika plus a pinch of ground cumin
- olive oil→avocado oil or any neutral high-smoke-point oil
- garlic powder→onion powder
- lemon→a few drops of balsamic vinegar or a squeeze of lime
Storage & reheating
Cool leftovers completely, then store in an airtight container in the fridge for up to 3 days. Reheat in the air fryer at 180°C for 3 to 4 minutes, shaking once, to bring back some crispness; the microwave will make them soft and is not recommended. For longer storage, freeze the cooked sprouts in a single layer on a tray, then transfer to a freezer bag for up to 2 months and reheat directly from frozen at 190°C for 6 to 8 minutes.
FAQ
The questions we get asked most
Why did my air fryer Brussels sprouts turn out soggy instead of crispy?
The usual cause is moisture or crowding. If the sprouts were still wet from washing, or if they were piled on top of each other in the basket, they steamed rather than roasted. Dry them thoroughly, toss with oil, and cook in a single layer, using two batches if necessary.
Should I cut the Brussels sprouts in half or leave them whole?
Halve them lengthwise through the stem. The flat cut face browns beautifully against the hot basket and the inside cooks through in about 12 to 15 minutes. Whole sprouts take closer to 20 minutes and often burn on the outside before the center is tender.
Can I use frozen Brussels sprouts in the air fryer?
Yes, but do not thaw them first. Toss the frozen sprouts with oil and seasonings, air fry at 190°C for 15 to 18 minutes, and shake the basket every 5 minutes. They will be slightly softer than fresh ones because freezing damages the cell walls, but they still brown well.
How do I know when the Brussels sprouts are done?
The cut sides should be deep golden brown and the loose outer leaves should be dark and crisp. Insert a paring knife into the core of the thickest sprout; it should slide in with no resistance. If the cores are still firm, add 2 more minutes and check again.
Can I make these ahead of time for a party?
You can trim and halve the sprouts up to 1 day ahead and keep them in a sealed container in the fridge. Toss with oil and seasonings just before cooking. Cooked sprouts are best served within 30 minutes, but leftovers reheat well in the air fryer at 180°C for 3 to 4 minutes.
Why are my Brussels sprouts bitter?
Older, larger sprouts and overcooked ones taste more bitter. Choose small, tight, bright-green sprouts, trim only the dry stem end, and avoid cooking past the point where the cut sides are golden. A squeeze of lemon or a light drizzle of balsamic at the end also balances any bitterness.
Can I add bacon or other toppings to this recipe?
This recipe is kept meat-free, but you can finish the cooked sprouts with toasted sliced almonds, grated Parmesan, a drizzle of tahini, or a sprinkle of chili flakes. Add any topping after air frying so it does not burn or steam the sprouts.
