How to Air Fry Brussels Sprouts

Trim the stem end flat and remove any yellow or damaged outer leaves. Halve each sprout through the stem — this creates a flat cut surface that caramelizes beautifully against the basket grate. For very large sprouts, quarter them. Dry the halved sprouts completely — any residual moisture from washing will steam the sprouts rather than roast them. Toss in a bowl with 1–2 teaspoons of oil (enough to coat without pooling at the bottom of the bowl), salt, and freshly cracked black pepper. Optional: a small squeeze of balsamic vinegar tossed in before cooking adds sweetness and depth.

Preheat the air fryer to 380–390°F for 2–3 minutes. Place sprouts flat-cut side down in the basket — the flat surface conducts heat from the basket grate and caramelizes to a golden-brown. Arrange in a single layer with space between pieces; overcrowding is the most common reason Brussels sprouts come out pale and soft. Cook for 8 minutes, then shake or use tongs to flip sprouts flat-cut side up. Cook for another 4–8 minutes. The outer leaves will crisp and darken significantly — dark edges are desirable and indicate flavor development, not burning.

The most popular Brussels sprout variations: balsamic glazed (toss with balsamic vinegar before cooking); parmesan (scatter grated parmesan over sprouts in the last 2 minutes); bacon Brussels sprouts (add air-fried bacon pieces after cooking and toss together); honey sriracha (mix 1 tsp honey and 1 tsp sriracha, toss after cooking); Asian-style (toss after cooking in soy sauce, sesame oil, and sesame seeds). All additions with sugar or dairy should be added in the last 1–3 minutes or after cooking to prevent burning.

The three causes of soft Brussels sprouts: (1) Overcrowding — the most common cause; steam builds up between pieces and they poach instead of roast. Never fill more than 60–70% of the basket. (2) Too much moisture — dry the sprouts thoroughly after washing. (3) Temperature too low — below 375°F, Brussels sprouts do not reach the caramelization threshold before they are fully cooked through. Stick to 380–400°F. A fourth less-common cause: very fresh, very dense sprouts from the refrigerator take slightly longer to soften than room-temperature ones — add 2 minutes if cooking cold sprouts straight from the fridge.

How long do you air fry Brussels sprouts?

Halved Brussels sprouts take 12–16 minutes at 380°F (195°C), shaken or flipped at 8 minutes. Small sprouts: 12–13 minutes. Large sprouts: 15–16 minutes. Toss in 1–2 tsp oil, salt, and a pinch of pepper before cooking. For extra crispiness on the outer leaves, cook to 16 minutes. For a tender-crisp texture, pull at 12–13 minutes. Overcrowding is the main cause of soft Brussels sprouts — spread in a single layer with the flat cut side down for maximum caramelization.

How do you get Brussels sprouts crispy in an air fryer?

Five steps for crispy Brussels sprouts: (1) Trim and halve them so you have a flat surface for direct contact browning. (2) Dry them completely — excess moisture steams instead of crisps. (3) Toss in oil (1 tsp per cup of sprouts) — no oil means no browning. (4) Single layer in the basket, flat-side down, with space between pieces. (5) Cook at 380–400°F for 14–16 minutes. The outer leaves will become dark and crispy — this is desirable. Sprinkle with salt immediately after cooking while still hot.
