Frequently Asked Questions
How long do brussels sprouts take in the air fryer?
+
Halved brussels sprouts take 12–16 minutes at 400°F in the air fryer, shaking the basket once at halfway. Toss with olive oil and salt. Cut side down at the start gets the best caramelization.
How long do I roast brussels sprouts in the oven?
+
Roast halved brussels sprouts at 425°F for 25–35 minutes, flipping once at the 15-minute mark. Spread cut-side-down in a single layer without crowding the pan.
Should I cut brussels sprouts in half?
+
Yes for roasting, air frying, or pan searing — halving exposes a flat face that caramelizes beautifully. Keep them whole for boiling or quick sautés of smaller sprouts.
Can I roast frozen brussels sprouts?
+
Yes. The air fryer handles them best — 18–24 minutes at 400°F, shaking every 6–8 minutes. Frozen sprouts release water, so pat them dry first if you can and give them extra time to let moisture evaporate before they'll brown.
