Air fryer Brussels sprouts cook quickly and come out caramelized and crisp on the edges. This guide covers fresh and frozen cook times, plus seasoning tips for flavor and crunch.
Roast at 375 °F for 12–18 minutes, depending on size and desired level of char:
| Size | Time | Notes |
| Small (halved) | 12 min | Tender with slight crisp |
| Medium (halved) | 15 min | Brown edges but soft inside |
| Large (halved) | 18 min | Deeper char, crispy outer leaves |
Pro Tips:
• Toss in oil, salt, and pepper.
• Shake basket halfway for even roasting.
• Finish with lemon juice or balsamic glaze for brightness.
Common Missteps:
• Not trimming stems results in uneven cooking.
• Overcrowding causes steaming, not roasting.
• Using too low a temperature leads to limp sprouts.
Summary:
Basically, at 375 °F, you’ll get perfect Brussels sprouts in 12–18 minutes—adjust timing based on size.
Want to reheat leftovers? Use the air fryer at 350°F for 3–5 minutes to bring roasted Brussels sprouts back to life with a crispy finish.
Bonus Tip:
Add bacon bits or parmesan in the last 2 minutes for extra flavor.
