How Long to Air Fry Brussels Sprouts

The short answer

For most batches, air fry halved Brussels sprouts at 400°F for 12–16 minutes. Whole sprouts usually need 18–28 minutes at 375°F, depending on their size. The sprouts are ready when the cut sides have crisp, browned edges and the centers are tender when pierced. Air fryer models vary, so begin checking a few minutes early, especially if the basket is small or the sprouts are unusually thin.

Halved versus whole

Halving gives Brussels sprouts more exposed surface area, so they brown faster and develop crisper edges. Place the cut sides facing down when possible for stronger contact with the hot basket. Small whole sprouts can stay intact, but larger ones may brown outside before the center softens; either halve them or add a few minutes. Keep pieces close in size so they finish together.

• Halved: 12–16 minutes at 400°F
• Small whole: 18–24 minutes at 375°F
• Large whole: 22–28 minutes at 375°F

Prep for better browning

Trim the dry stem ends and remove loose outer leaves. Rinse only if needed, then dry the sprouts thoroughly; surface moisture slows browning. Toss with just enough oil to lightly coat, along with salt and any dry seasonings. Too much oil can make the leaves greasy, while too little may leave the edges dry. Preheating is helpful but not essential if your appliance heats quickly.

Air-frying method

Preheat the air fryer to 375–400°F if your model recommends it. Arrange the sprouts in a mostly single layer, leaving room for hot air to circulate. Cook halved sprouts cut-side down for the first portion of the cooking time. Shake the basket or turn the sprouts halfway through, then continue until the edges are crisp and the centers are tender. A crowded basket may require an extra few minutes or a second batch.

• Use 400°F for faster browning on halved sprouts.
• Shake once halfway through cooking.
• Check early; smaller pieces finish sooner.

Finish and serve

Taste the sprouts as soon as they come out. A small squeeze of lemon or a splash of vinegar brightens their roasted flavor; add it after cooking so the sprouts keep their crisp edges. For a sweeter finish, toss with a little balsamic glaze or another prepared glaze just before serving. Add delicate toppings, such as grated cheese, toasted nuts, or fresh herbs, at the end.
